On Blow-Ins

Posted in Biographical, Maynooth with tags , , on May 25, 2026 by telescoper
ox-eye daisies

At the start of the spring gardening season I decided to leave a bed that I had cleared unplanted to see what would grow there of its own accord. I expected standard weeds like dandelions, and did get a few of those, but more recently I have a considerable number of Ox-eye Daisies (Leucanthemum vulgare). The flowers look very like those of regular daisies (of which I also have a few on the front lawn) but the plants are much bigger: I estimate they’re about 80cm tall. Anyway, I find the white and yellow very striking against the green foliage behind so I’m very happy to see these wild flowers thriving.

These must have blown in as seeds, along with the numerous other wild flowers I have in the garden. That reminds me that the term “blow-in” is used colloquially in Ireland to denote someone who has just moved into a town or village where they have no deep familial roots. I’ve been called a “blow-in” many times, not always in a friendly way.

This reminds me of  an article I saw in the Irish Times soon after arriving here about British immigrants in Ireland. Being one such myself I find a lot of it rings true. You can read the article here (I don’t think it’s behind a paywall). I think it’s well worth a look.

I found quite a few things in it resonate quite strongly with my experiences since I arrived here a couple of years ago. Top of these was the realization of just how ignorant I was about Irish history, thanks to the almost total neglect of this topic in British schools. Lack of education inevitably leads to lack of understanding and more often than not leads to prejudice and one finds a lot of that in the attitude of British people, even senior figures (many of them “educated” at Oxford) who are supposed to know better.

I was also struck by the “Not Really Irish” tag, which I think about rather a lot. It’s not really just a question of whether or not you have Irish citizenship or an Irish passport, it’s about the extent to which you belong. I spent over fifty years living in England and Wales so I’m missing a huge amount of cultural background pertaining to Ireland. I won’t ever be able to catch up all that so I don’t suppose I’ll ever feel `really Irish’. Of course people speak English here, but I’m very conscious that I have a funny accent. I suppose that means I’ll always feel like a stranger in Ireland. If there is predominant attitude towards the British over here, however, in my experience it is one of sympathy rather than hostility.

Anyway, since I am a metaphorical blow-in I suppose it’s only fair that I have so many literal ones in my garden!

Not in Barcelona…

Posted in Barcelona, Biographical, Maynooth with tags , , , on May 25, 2026 by telescoper

So much has happened since that it’s hard to believe that just two years ago I was enjoying a sabbatical in Barcelona. I was delighted when it was announced that this year’s Euclid Consortium Meeting would be held there, but when I saw the dates (25th to 29th May) I was worried that the meeting might clash with examining duties. When the examination timetable was published a couple of months ago, that possibility became a reality and I realized that I couldn’t attend. In fact I have an examination to deal with tomorrow, and will be grading the scripts for the rest of the week ahead of the Bank Holiday weekend.

It’s a shame I can’t make the EC meeting because this will be the last one before the first main release of data, DR1, which is scheduled to take place on October 21st this year. I’ve been following progress in the science working group on galaxy clustering via weekly Zoom conferences, but it would have been nice to see what has been going on in the other groups as well as catching up with colleagues in person as opposed to online.

The second data release, DR2 will not happen until March 2029, by which time I will have retired. In fact there will be at most two Euclid Consortium meetings that I can attend – in 2027 and 2028 – and the second of those may be after my retirement. The final data release, DR3, will happen in October 2031.

It’s worth also mentioning that there will be another Quick Release of data, this one from the Euclid Galactic Bulge Survey, on June 24 this year. There will be quite a lot of press activity around that, but I’m not involved in it.

Here is the complete timeline for reference:

I’d like to take this opportunity to wish everyone involved in the Euclid Consortium Meeting an enjoyable and productive time in Barcelona as well as a fun stay in what is truly an amazing city. I’ll be enjoying the beautiful weather in Maynooth (25°C and sunny) while all the participants are slaving over hot cosmology.

On My Knees

Posted in Biographical, Education, Maynooth with tags , , , , on May 22, 2026 by telescoper

It has taken a bit longer that I expected to get this far but I have now completed the grading of one of my modules. It wasn’t the written examination that took all the time, but the marking of the computational physics projects. This is always a slow job but for some reason it took even longer this year. Anyway, all components of the assessment for that module are now done and dusted and everything uploaded.

To add to the fun and games, last week I did the biannual trip to Naas for my anti-arthritis injections. I’ve been doing this regularly for some years now and it has become routine. When I first started I was told that there was a risk of one or both knees swelling up, but that has never happened. Until last week, that is. My right knee decided to swell up alarmingly. Although this was not really painful, I was forced to stay at home to rest and periodically apply a bag of ice. That worked well enough that I could go to last Friday’s concert (with the aid of a walking-stick) but it wasn’t until Sunday that I was properly recovered.

The alarm having passed I am now starting to feel the benefit of the jabs. I am planning sometime soon to walk from Maynooth to Dublin along the Royal Canal, that being the last leg of the National Famine Way. I want to be sure I can manage the 27km walk before attempting to do the full walk later in the summer. The weather is set fair for a few days so I might give it a go next week, assuming I manage to finish all my examining duties promptly. It’s the season finale at the National Concert Hall next Friday – followed by a long weekend break when I will be travelling a little, so I might try to do it on Thursday.

My next examination is not until Tuesday morning so, after several days of being shut away doing corrections, I can now spend a few days until the scripts are ready to collect doing numerous things that I’ve let slip while I’ve been busy. For one thing I have an inbox full of unanswered emails to attend to.

But for now I’m quite tired and in the mood only to vegetate.

Nottingham University Management Messages

Posted in Biographical, Education, Science Politics with tags , , on May 19, 2026 by telescoper

Last week I posted about the dire situation at Nottingham University and particularly in the School of Physics & Astronomy there. I since learned that I didn’t get the nunbers quite right: it appears that there are 71 staff in the School and 56 received notices that their jobs are at risk. There are 23 Professors in the School and 20 have received letters. The intention is that about 20 jobs will be lost across all academic and technical staff.

The open letter and petition here has already garnered over 2000 signatures, but more can’t do any harm.

I’ve heard also that staff at Notitngham are about to start a Marking and Assessment Boycott in response to the plans. This seems entirely reasonable to me and I would support further industrial action too. There is more about the situation in Physics World here.

I mentioned in my previous post that

Not all those in receipt of an “at risk” letter will actually be made redundant, but the intention is clearly to scare people into leaving in order to save on redundancy payments.

No doubt some positions will be saved by retirements and voluntary severance, but cuts on the scale being planned will be difficult to achieve without a significant number of compulsory redundancies. The messaging from the University Management is not subtle.

I have no idea what the management “plan” is at Nottingham, but I suspect it goes something like this, from the current Private Eye:

The effect of all this on staff morale will be devastating, but there will also be a practical effect. The more mobile, especially those with portable individual research grants, and those not tied to laboratories, will already be looking to move elsewhere. That will no doubt include some of Nottingham’s best researchers. It won’t be easy to move elsewhere in the UK, however, as the higher education system is collapsing. Other universities will no doubt follow a similar path,

Unfortunately, the recent goings-on at the Science and Technology Facilities Council will almost certainly be taken as a cue to shed posts in PPAN areas (Particle Physics, Astronomy and Nuclear Physics), as grants in these areas are to be drastically reduced. This is a clear signal that STFC wants the PPAN community to shrink. As far as I can see, Nottingham University currently employs about eleven Academic Staff in Astronomy and a similar number in Particle Cosmology.

On a personal note, in the interest of full disclosure, I joined Nottingham University as Professor of Astrophysics in January 1999. Neither of these groups existed then and the School of Physics (as it was) was struggling in the doldrums. The incorporation of Astronomy led to the name being changed to the School of Physics & Astronomy, led to a boost in undergraduate recruitment and improved research assessment outcome. The Particle Cosmology group came a bit later. The University’s original plan for Astronomy was just one Professor and two lecturers! I pushed particularly hard for this when I was there. I left Nottingham in 2007 and watched from the outside as both groups prospered over the years, due not only to teaching and research but also to an effective outreach campaign centered around Sixty Symbols. I feel very sad to see their future so drastically threatened.

While I am on the subject of messages, the Vice-Chancellor of Nottingham University, Jane Norman, has recently announced publicly that she thinks the University might go bust by 2031 without these cuts. Now, if you were a prospective Nottingham University student, how would you respond to a statement that the University you are thinking of applying to could run out of money in five years? The VC can’t possibly imagine that recruitment will remain buoyant in this situation, can she? Her blundering attempt to justify the planned cuts brings the prospect of a death spiral at Nottingham closer.

As James Binney put it in his comment on the open letter:

If these redundancies go ahead, the best physics faculty will leave Nottingham, outstanding candidates will no longer accept offers from Nottingham and the quality of the student body will rapidly decline. It takes generations to create a world-class department, but one can be destroyed in less than a decade.

Jobs Under Threat at Nottingham University

Posted in Biographical, Education with tags , , on May 14, 2026 by telescoper

I saw this picture on a LinkedIn post from a former member of staff in Physics at Nottingham University:

It shows a notieboard in the foyer of the Physics Building, which houses the School of Physics & Astronomy. Earlier this week members of staff received letters informing them that their jobs are “at risk of redundancy”. As an act of solidarity the staff members concerned showed posted their letters publicly. I don’t know the names of the people who have received these letters – and if I did I wouldn’t share them here – but there are 17 letters.

UPDATE: I have since heard that 56 members of academic staff in the School – out of a total of 71 – have received these letters. The University wants to reduce the staff numbers in Physics & Astronomy by about a third.

I also know that the undergraduate course in Mathematical Physics, taught jointly with the School of Mathematics, has been suspended and will not admit any students. I taught on this course for many years when I was at Nottingham University (from 1999 to 2007).

The threat of redundancy is not specific to Physics. It seems almost 2,700 individuals across the University have received such notices and the University is attempting to cut 600 positions. Not all those in receipt of an “at risk” letter will actually be made redundant, but the intention is clearly to scare people into leaving in order to save on redundancy payments.

More details can be found here.

There is a petition against these job cuts here which I encourage you to sign.

The background to this disaster is explained here. In summary, the University’s current financial meltdown is caused by the actions of the former Vice-Chancellor of the University of Nottingham, Prof. Shearer West,, who presided over the hare-brained decision to purchase a large new campus. None of the “at risk” staff is at fault., but they will have to bear the burden of management ineptitude. You would think that the people responsible for this fiasco would be held to account and pay at least some of the price for their incompetence. But no. Prof. Shearer West left her post in 2024 to take up the position of Vice-Chancelor at the University of Leeds on a salary of more than £330K, leaving others to clean up the mess.

I fear more such news is coming. The UK Higher Education sector is shrinking rapidly. Nottingham University won’t be the last, and I doubt the contagion will be restricted to the UK either…

Lectures’ End

Posted in Biographical, Education, Maynooth, The Universe and Stuff with tags , , on May 8, 2026 by telescoper

At last we’ve made it to the end of term. This morning I delivered my last particle physics lecture. Given that it is the last day of the semester I was half-expecting no students would turn up, but in the end I had about 60% attendance. At the end of my lecture there was even a smattering of applause, which I interpreted as meaning that the students were happy that I’d finished.

I thought I would end this module with some topics that I didn’t have time to cover in any detail, but thought the students should know at least something about. These loose ends included:

  • Renormalization
  • Grand Unified Theories (GUTS)
  • Supersymmetry (SUSY)
  • Particle candidates for Dark Matter
  • Baryogenesis

I only had time for a superficial treatment of these topics, but felt the class should at least hear the words. There are some very good unanswered research questions under those headings, which I think is an appropriate way to end a final-year module, given that at least some of the class are intending to carry on to further study in physics.

This afternoon we had a colloquium by our PhD student John Ibrahim on the subject of the “Quark‑Gluon Vertex and Confinement of Quarks”. It was a nice talk but it struck me how big the gap was between what I’d been teaching at undergraduate level and the standard that a PhD student has to reach.

Today was also the deadline for Computational Physics projects. I’ll be grading them next week. Even then the term won’t quite be over – there is the small matter of exam marking to be done – but at least I’ve got no more formal teaching to do until September.

Last night on the way home I decided to buy a nice bottle of white wine and put it in the fridge so I could drink it in celebration of the end of term when I get home, with a nice fish supper.

Last Chance Lab

Posted in Biographical, Education, Maynooth with tags , , on May 7, 2026 by telescoper

Today is the penultimate day of teaching in the Spring Semester at Maynooth University and I’m here in the Computer Lab for the last time. This afternoon’s session is just a drop-in consultation session for Computational Physics students doing their projects and although it has been busier than previous weeks it has not exactly been a hive of activity. The deadline for project submissions is tomorrow afternoon, so I was expecting a bit of a rush at this session, which is the last of its type, and also at my office hour this morning. I did have one student attend this morning, and a couple of others this afternoon, but other than for them it has been quiet.

On the other hand, over a day before the deadline, three students have already submitted their project reports and code. I’m impressed with that, but also a little surprised. I’ve come to expect just-in-time delivery for such things.

Yesterday I did my last particle physics tutorial of the year and followed that immediately afterwards I attended a long session of final-year project talks, from 3pm to just after 6pm. It is obvious that some students find these presentations a bit of an ordeal but it is important to learn how to present your work so such things are part of the rite of passage. It is good for staff to get an overview of the all projects being done in the Department too.

In previous years the final project presentations for students in the Departments of Theoretical Physics and Experimental Physics were done separately, the former having a somewhat smaller audience than the latter. The two previous Departments having merged into a single Department of Physics, this time round we had all the talks together (though spread over two days, yesterday and the Wednesday before). I think the combined sessions worked quite well and we will probably do it this way next year.

After the session of talks there was a small drinks party in the foyer of the Science Building. That was a nice occasion, and it struck me that it would have been the last time this group of students would all meet together until their graduation. Tomorrow I do my last particle physics lecture and it will be the last time I see quite a few of the students in that class until graduation too. They’ve been a nice group to work with, very engaged and easy to interact with. It is a great pleasure to be teaching students who are eager to learn . That’s the aspect of academic life I’ll miss the most when I retire.

Back to May(nooth)

Not May Blossom (actually Common Pearlbrush)

So here I am, back home in Maynooth after a long weekend away in Not Maynooth. The weather forecast for Maynooth was typically dreadful for a Bank Holiday weekend but I have to say I can’t sign see much sign of the heavy rain that was predicted.

On the way back I checked the cricket scores and discovered that Glamorgan won their County Championship game against Hampshire by an innings and 69 runs. That’s worth marking on this blog because it is their first win in Division One since 2005. Historic. Their first three games this season ended in a defeat and two draws, so it was 4th time lucky. Well played to them!

Anyway the last four days of teaching term beckon, including a 9am lecture tomorrow morning, so I had better leave it at that and try to get into a work frame of mind.

Thoughts on 1st May

Posted in Biographical, Education, Maynooth with tags , , , on May 1, 2026 by telescoper

Today, 1st May, Beltane (Bealtaine in Irish), is an old Celtic festival that marks the mid-point between the Spring Equinox and the Summer Solstice. It’s one of the so-called Cross-Quarter Days that lie exactly halfway between the equinoxes and solstices. These ancient festivals have been moved so that they take place earlier in the modern calendar than the astronomical events that represent their origin: the halfway point between the Spring Equinox and Summer Solstice is actually next week. Anyway, “May Day”, Lá Bealtaine in Irish, is today – the name Bealtaine applies to the whole month of May.

In Ireland the Bank Holiday associated with Bealtaine is on Monday 4th May, so another long weekend beckons.

Workwise, after today we will have completed the penultimate teaching week of Semester 2 so after Monday’s Bank Holiday we will have just four official days of teaching left, before a Study Week and the start of examinations. Yesterday I correctedthe last of my Computational Physics class tests so I am up to date with the continuous assessment and feedback of both my modules. I now have a week before the Computational Physics projects are submitted, and another week before the exam period starts.On Wednesday last we had project presentations for about half of the final year class; the other half do their things next Wednesday.

Now, I have a particle physics lecture to give – the antepenultimate one of the semester – after which I’ll be launching myself into the long weekend.

Lá Bealtaine shona daoibh go leir!

A DESI Milestone

Posted in The Universe and Stuff, Biographical with tags , , , , , on April 29, 2026 by telescoper

Yesterday the Open Journal of Astrophysics published a paper by Porredon et al which will feature in the usual Saturday round-up. That paper, which is based on the First Data Release from the Dark Energy Spectroscopic Instrument (DESI) reminded me that I should mention that DESI recently reached an amazing milestone – it has now mapped the positions and redshifts of 47 million galaxies and quasars! There is a full press-release about this achievement here.

Here’s a little video showing how the survey works:

There are more videos and other graphics in the press release.

Here’s a nice picture showing a thin slice through the full survey that reveals the characteristic “cosmic web” of the large-scale structure of the Universe in all its glory:

This progress is great, but it really makes me feel old. Forty years ago, in 1986, I had just started my PhD. The state-of-the-art galaxy redshift survey slice then is shown in this plot, from de Lapparent et al 1986 (ApJLett 302, L1), one of the first papers I read as a research student (I got it in 1985 as a preprint), which contains just 1,100 galaxies:

It is worth mentioning that although DESI has now covered its original target area, it will continue until 2028. You can never have too many galaxy redshifts!
