Back to the Office

Posted in Barcelona, Biographical, Maynooth, The Universe and Stuff on June 30, 2025 by telescoper

After a week away in Cork, I’m back in the office at Maynooth University. I have quite a lot of things to do before my next trip away which will be next week.

On Friday (27th) Maynooth students got their examination results. For this year’s finalists that means they also received news of their final degree classification. I’ve seen quite a few celebratory messages flying around on social media so let me add my own congratulations here: Congratulations!

We’ve had an outstanding group of students in Theoretical Physics this year and that is reflected in some excellent degree results. Well done to them all, and best wishes for the further studies on which many of them are about to embark.

Tomorrow (Tuesday 1st July), we have a consultation day during which students can ask about their examinations and request advice on next steps, including repeat examinations in August, the papers for which have to be readied for printing in the next two weeks.

Campus is quiet at this time of year, as most of the undergraduate students have left for the summer (or permanently for the graduands). A few will remain to do summer projects. The postgraduates are still around, of course. I have a Masters student doing their project this summer, from which I hope a paper will emerge, and a PhD student doing post-viva corrections to her thesis. I’ve also got a couple of other papers to finish.

I’m hearing a lot about sweltering temperatures across Europe. Fortunately it is more temperate here in Ireland, with maximum of 23 degrees forecast in Maynooth. All of this reminds me that it was a year ago today that I returned from a spell in Barcelona on sabbatical. As it happens, I met my hosts Licia and Raul at EAS last week. It seems things are going well at ICCUB. I would have stayed longer there, but my laptop had died which left me unable to work effectively. I’m looking forward to visiting there again next year for the 2026 Euclid Consortium meeting (if I can find the time).

An AI Guide to Europe

To assist those readers who might be planning conference trips or vacations in Europe I thought I’d share this helpful map (which I found here) that was generated by one of those famously accurate AI apps. There may be a few small errors, but I’m sure they are insignificant:

Apart from everything else, this explains why I found Barcelona much warmer than I had expected when I was there last year…

The Spanish Power Outage

Posted in Barcelona, Biographical, Euclid with tags , , on April 28, 2025 by telescoper

The first I knew about today’s massive failure of electricy grids across the Iberian peninsula was at 4 o’clock this afternoon, when I tuned in to a regular Euclid telecon and found that the expected speaker wasn’t able to give their presentation because there was no power in Spain. I was subsequently shocked to discover the scale of the outage, the cause of which remains unknown (at least to me). I’ve often thought that Ireland’s power grid was a bit unstable but I’ve never known the whole country to be shut down!

It all reminded me of the 2003 power blackout in the North-Eastern USA and Canada.

There has been speculation about an “unusual atmospheric phenomenon” being the cause, but that seems somewhat implausible. Indeed, nothing I’ve read so far about the cause of this event makes much sense.

This time last year I was in Barcelona, and today’s events got me thinking what it would have been like to be there without any power. The apartment I was living in was all-electric so there would have been little I could do – no light, no cooking, no air conditioning, no internet, no TV, no radio. I was on the top floor and the lift was powered by electricity so I would have had to use the stairs to get in or out. It would have been an interesting experience to see the city in total darkness from my balcony.

Had I been in the Department of Physics when the power went off I probably would have had to walk home, as the Metro would not have been running and with all the traffic lights off the roads would be even more chaotic than usual. That would have meant a walk of an hour or so, which would have been annoying, but feasible. Come to think of it, people actually on the Metro when the failure happened would have been stuck in a tunnel which must have been very unpleasant.

Anyway I hope all my friends and colleagues in Spain are not too badly inconvenienced and that this very weird event doesn’t lead to any serious issues. I understand the power supply to hospitals is secure, which is a relief. I must admit though I am very curious to learn the cause of this catastrophic failure. Was it human error? Deliberate sabotage? Or was it really an “unusual atmospheric phenomenon”? No doubt there will be a full investigation and we’ll find out in due course.

2024 in Retrospect

Posted in Barcelona, Biographical, Cardiff, Maynooth with tags , , , , , on December 31, 2024 by telescoper
What we call the beginning is often the end
And to make an end is to make a beginning.
The end is where we start from.

T. S. Eliot, from Little Gidding, the last of the Four Quartets.

I wasn’t really planning on posting a retrospective of the year 2024, but the rain is pouring down outside so I’ve decided to use up a bit of time before going out in the hope that the rain stops.

The past year has been very busy with significant life events. One particular highlight has to be a wonderful once-in-a-lifetime trip to Sydney in February. I don’t know if I’ll ever get the chance to visit Australia again, but if I do I’ll take it! Shortly after returning from that trip I went back to Barcelona until the summer, leaving briefly for visits to Rome (Euclid Consortium Meeting), Valencia (Department Colloquium), Newcastle (to do a PhD examination) and Oxford (to give the inaugural Pride talk at the Department of Physics).

Unfortunately, at that point my laptop gave up the ghost so I had to come back to Maynooth a little earlier than planned to salvage what was on it and get a new one. And so ended my sabbatical. I’d like to take the opportunity again to thank everyone at the Universities of Barcelona and Sydney for making me feel so welcome and, of course, to Maynooth for granting me a full-year sabbatical in the first place.

As well as giving me some time for my own research, the year saw significant progress with the Open Journal of Astrophysics, both in terms of numbers of papers published (120 in 2024) but also some much-needed work on automation and an increase in the size of the Editorial Board. It’s hard to predict what will happen in 2025, but I’m glad that a significant number of members of the astrophysics community seem to be regarding OJAp as a viable avenue for communicating their results.

I will also mention – for those that care – that the Open Journal of Astrophysics is now listed in Scopus, but all the numbers they have published about the journal are inaccurate. I have spent months trying to get them to correct the figures but, although they have admitted errors, they have failed to do so. My next step will be to take legal action against Scopus (which is based in The Netherlands) under the Dutch Civil Code.

The big event workwise at Maynooth was the merger of the Departments of Theoretical Physics and Experimental Physics into a single Department of Physics. So far this has been largely paper exercise. What will result from it in the long term remains to be seen. I was given two new modules to teach last Semester and have another new one next Semester (as well as one I’ve done before). Although this made for a heavy workload, it wasn’t as bad as what happened after the only other sabbatical I’ve had in my career. I got a one Semester sabbatical when I was at Nottingham, but the Department simply moved my first-semester teaching to the second semester in addition to what had already been allocated for the second, so I had a double teaching load when I got back!

There has been a significant change in my personal circumstances too. During 2024 I finally completed the sale of my former home in Pontcanna, Cardiff. I had intended to do this years ago, but the pandemic and subsequent workload issues made it difficult to travel and sort this matter out. In the meantime bought my house in Maynooth with a mortage so I owned two properties, one of which was empty for much of the time. After much stopping and starting, and being badly let down by more than one prospective buyer, the Cardiff house is now sold. I now feel much less delocalised. I also felt very rich when the proceeds hit my bank account, but only briefly. I used a big chunk to pay off my mortgage and put the rest into fixed-term investments for retirement.

Anyway, writing about Sydney reminded me that there are parts of the world in which it is 2025 already, so let me end with a “Happy New Year” and a few interesting numerological facts about the number 2025:

P.S. It’s still raining.

P.P.S. Athbhliain faoi shéan agus faoi mhaise daoibh! 

New Results from DESI

I’ve just got time between meetings to mention that a clutch of brand new papers has emerged from the DESI (Dark Energy Spectroscopic Instrument) Collaboration. There is a press release discussing the results from the Lawrence Berkeley Laboratory here and one from the ICCUB in Barcelona here; several members of the group I visited there during sabbatical are working on DESI. Congratulations to them.

I haven’t had time to read them yet, but a quick skim suggests that the results are consistent with the standard cosmological model.

The latest batch contains three Key Publications:

together with the companion supporting papers:

The links lead to the arXiv version of these papers. These articles can also be found, along with previously released publications by the DESI Collaboration, here.

Farewell to Barcelona

Posted in Barcelona, Maynooth with tags , , , on June 30, 2024 by telescoper

Two things threatened to complicate my return from Barcelona today.

The first was industrial action by Aer Lingus pilots, which started last week. When the list of cancellations caused by the first stage of this ( a work to rule) was announced, I checked to see which flights were affected and found the Barcelona-Dublin route wasn’t among them.

The other matter was Taylor Swift’s residence of three concerts in her ‘Eras” Tour in Dublin this  weekend, making flights very busy (and more expensive than usual).

Taylor Swift was performing in Sydney when I was there earlier this year and in   the UK when I was there earlier this month. I think she’s following me around. I’m sure she only wants me for my money…

Anyway, owing to the combination of these circumstances, and the probability of escalation of the industrial dispute, I decided not to take a chance on Aer Lingus but instead to opt for an early morning flight with Ryanair. Although I had to get up at 4am (3am Irish Time) to get the plane back to Dublin, all went according to plan. The Barcelona airport bus, incidentally, runs all night.

My own personal ‘Eras’ Tour (i.e. sabbatical) is not over until the end of August, but I’ll be spending the rest of it somewhere a bit cooler and with less hustle and bustle. But first I have to get my laptop sorted…

It just remains for me to thank publicly the staff and students of the ICCUB,  especially Raul and Licia, for making me so welcome in Barcelona for the past 9 months (off and on).

Now I think a little siesta is called for…

Como si fuera esta noche la última vez

Posted in Barcelona, LGBTQ+ with tags , , on June 29, 2024 by telescoper

This afternoon, it being my last full day here, I decided to make a farewell tour of Barcelona. I shall miss this place, as the streets have become quite familiar. Two things I won’t miss are the crowds of tourists in some quarters and the heat – it was 28° C at 6pm.

Anyway, my walk included a last ramble up La Rambla from the old harbour towards my flat. I thought it looked unusually quiet when I started, but then realized there was a big crowd at the top end (where it joins Plaça de Catalunya). Pride month in Barcelona started yesterday (28th June, LGBT Pride Day, the anniversary of the start of the Stonewall Riots) and goes on for about a month. This demonstration was a kind of counter to the “official” Barcelona Pride events, a protest against excessive commercialization, pinkwashing, homophobic and transphobic violence, among other things. Pride is, and should be, a protest.

Fundació Joan Miró 

Posted in Art, Barcelona with tags , , on June 28, 2024 by telescoper

My time in Barcelona is rapidly drawing to a close so I thought I’d spend the morning visiting the Fundació Joan Miró, which is situated in the Parc de Montjuïc with excellent views of the City. Quite apart from the strange and wonderful collection of things inside, it’s just a beautiful space to wander around; there’s a sense of light and space which is very refreshing. It took no longer than 30 minutes to reach it from my apartment, via the Metro L3 and the funicular railway from Parallel which takes you within 5 minutes’ walk of the building.

As well as the permanent collection of works by Joan Miró, there are pieces that influenced his development as an artist, such as the 14th Century altarpiece shown above: in his early years, Miró experimented with the very flat perspective often deployed in mediaeval art. The exhibition includes a large range of materials, including sailcloth and wool as well as the more usual oil and canvas; there’s also a mercury fountain. There is also a temporary exhibition by Vietnamese sculptor Tuan Andrew Nguyen whose creations include dynamic shapes evoking explosions made from fragments of unexploded bombs found in his homeland in the aftermath of the Vietnam war.

To Valencia!

Posted in Barcelona, Open Access, Uncategorized on June 25, 2024 by telescoper

Ailing* laptop notwithstanding, I’ll shortly be taking the train to Valencia where I’ll be giving a talk tomorrow. The trip is about 350km each way and takes about 2 hours and 50 minutes. That’s a bit slower than the very fast train to Madrid but it looks like it’s all along the coast, so hopefully it will be quite enjoyable.

*I managed to get it to boot up into Windows, but it is running so extremely that I can’t do much on it. I have no idea what the issue is.
