Exploring the Cosmos at Maynooth

Posted in Maynooth, The Universe and Stuff with tags , , on September 21, 2023 by telescoper

Regular readers of this blog – both of them – may remember that last year there was an event at Maynooth University entitled Exploring the Cosmos which was very well attended, with over 400 people showing up. That event was held during Space Week 2022 and it was such a success that it’s being repeated during this year’s Space Week.

I gave a talk at last year’s event but won’t be there this year as I’ll be away on sabbatical. Some of the other speakers are different too. The fact that the line-up has changes is good because it means that people who came last year will get a different set of presentations.

On the 5th of October, at 6.30pm, in the TSI Building Maynooth University will host an all-ages event to explore the vastness of space. Using stunning visualisations Maynooth University Astrophysicists will examine star and planet formation, peer back in time with our physicists trying to image the very edges of our visible universe, and take a journey into the unknown as we trace the origin and evolution of black holes.

Programme:

18.30 Welcome

18.35: John Regan: “Black Holes in Our Universe”

Black Holes are among the most exotic objects in our Universe. In this talk John will discuss the basics of black hole formation, how we can detect them today and the future of black hole hunting using gravitational wave observatories that Maynooth University is a part of. John will also discuss some of the strange effects you might encounter near a black hole – like time slowing down!

18.55: Aoibhinn Gallagher: “The Dark Universe”

There is so much in our universe which is unknown to us, most of it in fact. What is dark matter, what is dark energy? We will go on a journey during this talk through the history of our universe and the history of cosmology (the study of the universe) itself to try and arrive at answers to these questions. Also I will talk about the real life science happening at Maynooth university on these very topics.

19.15: Tea & Coffee Break

19.45: Neil Trappe: “Seeing the Invisible Universe – Terahertz Astronomy”

When you look outside at the clear night sky you will see many thousands of stars overheard. The Moon, stars, planets, comets and galaxies can all be observed if you know where to look just using your eyes, binoculars or a telescope.

Astronomers spend many hours looking at the night sky with large automated telescopes from many exotic places around the world to add to our knowledge of the Universe and understand difficult questions like how did the Sun and our Solar System form, how are stars born and how do they die, is there life elsewhere in the Universe, and indeed how did the Universe come into existence at all?

In Maynooth University a team of researchers develop telescopes to see the Universe with different kinds of light, specifically far infrared or “terahertz” light. Why do we do this – we see the Universe differently and can learn lots more information ‘seeing’ with terahertz radiation that is invisible to our eyes.

20.05: Patrick Kavanagh: “The First Year of the James Webb Space Telescope”

The James Webb Space Telescope has made unexpected and groundbreaking discoveries almost routine in its first year. It has produced captivating images of our own Solar System, measured the content of atmospheres around other stars, viewed the stellar birth and death in amazing detail, revealed the skeletal structure of galaxies, and peered deep in to the cosmic past in search of the first stars and galaxies. In this talk Dr. Kavanagh will give an overview of Webb and present some of the highlights of the first year of this revolutionary telescope.

20.30: Finish

It should be a fun evening. If you’re around please come along. This event is free to attend but you need to register, which you can do here. Please feel free to share this with friends and colleagues.

Welcome (and Goodbye) Week

Posted in Biographical, Education, Maynooth on September 18, 2023 by telescoper

So Welcome Week has started in Maynooth, although I’m keeping a low profile ahead of my departure to foreign climes and haven’t seen any of the new students, who I’m assured definitely exist. I will be on campus tomorrow though as I have various things to do in my office before handing over the keys until next year. I think pint or two may well be drunk at some point this week to celebrate my departure too.

Although I’m not involved in Welcome Week activities, this week is nevertheless going to be extremely busy, and not just because of preparations for my trip to Barcelona. After a short hiatus in December, Euclid developments are well and truly back and I’ve got a stack of telecons to deal with. I had three today, and that’s just the start. I won’t get away from those while on sabbatical, of course, but at least I don’t have to organize them around teaching and other departmental activities.

I was chatting with my PhD student online this afternoon and it struck me that this will be the first time since 2020 that the Autumn Semester will start properly at Maynooth and students will get a full twelve weeks of in-person teaching with a study week. For the three previous years, teaching started late for new students because of a knock-on effect of the Leaving Certificate results being delayed by Covid-19 reasons. That meant that there was a truncated orientation process and term was a week shorter, i.e. 11 weeks instead of 12. I have been teaching first year physics students during that period, and it was quite a headache figuring out how to tweak things to make everything fit without rushing too much. Now all that is behind us, and a more relaxed start of term is possible, but it’s my successor in the role of first-year lecturer who will reap the benefit.

Teaching term starts later in Maynooth than in many other Irish universities. This year lectures commence on 25th September, a week today, by which time I’ll be in Barcelona. This has its advantages, but the disadvantage is that teaching is supposed to carry on until Friday December 22nd, just three days before Christmas…

Physics as Fun

Posted in Biographical, Education, Maynooth on September 13, 2023 by telescoper

To add to all the excitement I’ve just had a visit from a representative of ESB Networks who installed a new “smart” meter at my house in Maynooth. That process involved cutting off the electricity for about 15 minutes, which was long enough to set off my burglar alarm. Now that’s sorted, I have to go round resetting the clocks. All of that after I wasted half an hour this morning watching my laptop do compulsory Windows updates which involved two restarts.

Anyway, despite the distractions I’ve been working busily at home and getting ready for my departure abroad. This is the first year for a while that I haven’t been involved in Welcome Week or the Student Orientation process, which are ongoing. I have, however, looked at the online registrations so far and confirmed that there will indeed be some students in Theoretical Physics for the forthcoming academic year.

Yesterday I saw this cartoon by Gary Larson so thought I’d share it here.

It reminded me of this picture I have in the past shown at Open Days

I think there are many people out there who think physics, especially theoretical physics, isn’t something to be enjoyed. I think it is, or at least that it can be. I also think the best way to succeed at physics is by enjoying it, and I hope the new and returning students at Maynooth enjoy their theoretical physics over the next year while I am slaving away on sabbatical in Barcelona…

From Einstein to Euclid: the Gallery

Posted in Biographical, Maynooth, The Universe and Stuff with tags , , on September 11, 2023 by telescoper

Last week I posted a photograph taken during my public lecture at Maynooth University. I thought I’d compound your collective misery by putting up more. I’m not sharing any pics of the audience because we didn’t ask them for permission, so you’re basically stuck with pictures of me (and one of Joost Slingerland, our Head of Department, in the first one).

Thanks to Dale for taking the pictures!

DolanFest

Posted in Maynooth, The Universe and Stuff with tags , , , on September 9, 2023 by telescoper

This morning found me in Renehan Hall in St Patrick’s House in Maynooth for ‘DonalFest’, a meeting to mark the retirement of former colleague (now Emeritus) Professor Brian P. Dolan, who retired a couple of years ago in the midst of the pandemic, which delayed his leaving do.

Today’s meeting involved a number of talks given by Brian’s past and present collaborators in the splendid surroundings of the old college (and, I might add, in glorious weather). Unfortunately I had to leave before the end in order to attend to some logistical matters to do with my impending departure on sabbatical, but I’m sure the rest of it was as enjoyable as the bit I was able to be at.

All of which gives me an excuse to plug again this textbook (left), based on the lecture notes Brian used to teach a final-year undergraduate course in General Relativity to Mathematical Physics students here in Maynooth.

The book’s description reads:

Einstein’s general theory of relativity can be a notoriously difficult subject for students approaching it for the first time, with arcane mathematical concepts such as connection coefficients and tensors adorned with a forest of indices. This book is an elementary introduction to Einstein’s theory and the physics of curved space-times that avoids these complications as much as possible. Its first half describes the physics of black holes, gravitational waves and the expanding Universe, without using tensors. Only in the second half are Einstein’s field equations derived and used to explain the dynamical evolution of the early Universe and the creation of the first elements. Each chapter concludes with problem sets and technical mathematical details are given in the appendices. This short text is intended for undergraduate physics students who have taken courses in special relativity and advanced mechanics.

You can order the book and/or recommend a copy to your library here.

Anyway, let me end with some personal wishes to Brian for a long and happy retirement!

ITP 2023

Posted in Biographical, Education, Maynooth, The Universe and Stuff on September 6, 2023 by telescoper

So here we are then, first day of the 2023 Irish Theoretical Physics meeting here in Maynooth. It’s a busy schedule for the three days, followed by a little meeting on Saturday to mark the retirement of Brian Dolan

It’s been a busy day for reasons other than the ITP2023 and I’ve left it a bit late to write my talk for this evening’s public lecture so I’d better get on with that this afternoon.

Updates to follow.

The Centre for Astrophysics and Space Science at Maynooth (CASM)

Posted in Maynooth, The Universe and Stuff with tags , , on September 5, 2023 by telescoper

As part of effort to bring about closer interactions between members of the Departments of Theoretical Physics and Experimental Physics at MaynoothUniversity, we have formed a Centre for Astrophysics and Space Science which now has its own web pages.

The members of CASM have been meeting regularly together for coffee on Tuesdays for over a year, during which time more people have joined the Centre.

Today being a nice day we decided to make a team photograph showing staff, postgrads, and postdocs split roughly evenly between the two Departments. There’s also an undergraduate who has been working with us through the summer and helped to set up the web pages.

The People of CASM

Not everyone was able to be there this morning, but it’s lovely to see the group as big as this. I think it will be even bigger when I get back from my sabbatical next year…

September Heatwave

Posted in Biographical, Maynooth with tags on September 4, 2023 by telescoper

What a lovely day to be on sabbatical! It seems that the weather is set fair for a few more days too, which is nice. You don’t often see a satellite image with not a cloud in the sky over Ireland.

It’s cute that the Met Éireann weather map gives a red temperature warning when it’s just 23 °C.

Mind you, it has felt very warm today. So much so that I had a short nap this afternoon. I think of this as training for what I hope will be the regular siesta…

The Higher Education Market

Posted in Education, Maynooth with tags , , , on September 3, 2023 by telescoper
Iontas Lecture Theatre, Maynooth University

Last week I was talking to a current undergraduate student who has been working in the Department of Theoretical Physics over the summer. After a while the conversation turned to the possibilities for postgraduate education. I’ve had that sort of discussion many times over the years with many different students, but the curious thing is that I always find it quite difficult because I’m torn between competing motivations.

On the one hand, there is the wish to have the best undergraduates stay on for further study in the Department. That of course helps our research, but it is also good for our finances as postgraduate students bring income. I think we offer good opportunities at both Masters and Doctoral levels, so it’s not too difficult to point these out to students in a way that at least some find persuasive.

On the other hand, there is the fact that I am an academic not a salesman and I feel that it is my responsibility to give honest guidance. The fact is that a good undergraduate degree from the National University of Ireland will open a lot of doors elsewhere, and these should be considered. At Masters level in particular, there are excellent courses available in the EU which have the advantage of not charging fees at the level they are charged in Ireland. Add to that the cost of living and accommodation crises. It’s no surprise that many of our graduates seize opportunities to go to postgraduate study in Germany, Denmark or The Netherlands (to name just a few). I have no problem with explaining the advantages of options outside my own Department and no doubt some students find these points persuasive too.

There’s a wider context for this type of dichotomy, namely the progressive marketisation of higher education. When it comes to recruiting undergraduate students we academics are increasingly required to act as reps for the University, hawking our wares at Open Days, Recruitment Fairs, and a variety of online events. I’m reasonably happy to participate in these when asked to do so, but I always take the approach of describing what we do in our Department rather than trying to do down what happens elsewhere. I’m an academic not a salesman. And I work in a public university, not a private business. I see my job as giving advice in as objective a way as possible. If I feel that our courses would not be the right choice for a student, I’ll explain why. In the end, of course, the decision is up to the student, but I feel obliged to give them enough information to make an informed choice.

A couple of years ago, the (then) new President of Maynooth University walked up to the Theoretical Physics stand at a Maynooth Open Day when I was on duty. The first thing she said was “Sell your course to me”. I described what we had on offer, but I don’t think what I said impressed her at all. We can only hope to succeed in recruiting students who have some interest in science. An Open Day is a bit late to cultivate that: interest has to be nurtured from an early age.

Another problem I find, speaking as a physicist (though this is probably also true for people in many other disciplines), is that we see physicists in other institutions as colleagues rather than business rivals. This is particularly true for those of us working in large consortia that spread over many departments (and indeed many countries). I therefore see myself as a physicist who happens to work at Maynooth University rather than as an employee of Maynooth University who happens to do physics. It’s not that I am disloyal to my employer, it’s just that I have a greater loyalty to a larger community.

I do understand that the reality of the funding system here means that we have to be able to recruit students in order to pay our way, but I feel that the way to achieve that is by establishing a strong reputation in our core academic mission of teaching and research rather than through marketing gimmicks, corporate branding, or other forms of commercial flummery. No amount of propaganda will disguise a higher education institution that neglects those things that higher education is about.

The Sabbatical Starts Here…

Posted in Biographical, Maynooth with tags , on September 1, 2023 by telescoper

Today is 1st September 2023, which means that it is the first day of my year-long sabbatical. No teaching and no admin until 31st August 2024! I moved the last of my personal things out of the office yesterday and put an auto-reply on my email. I did plan to take today off to celebrate but I had some things to do relating to the Open Journal of Astrophysics so I spent the morning doing them. If the rain holds off I might do a spot of gardening later on.

A sabbatical isn’t a holiday of course, and will have plenty to do over the next year, much of it clearing a backlog of things I should have done well before now but failed because of workload issues. I make no apology for taking the first day off, however.

Next week will be quite busy. I will be attending a meeting in Maynooth next week and giving a public talk, which gives me the chance to post a reminder that it’s not too late to register for either/both:

Another thing I did last night was to deactivate my own personal Twitter account as well as the one for the Open Journal of Astrophysics. Twitter is both unpleasant and useless these days and I can’t be doing with it anymore. I had been on it for 14 years and had accumulated over 7,000 followers. Those that want to carry on following me on social media will find me on BlueSky or Mastodon. The same goes for those who followed the Open Journal of Astrophysics on Twitter.

Anyway, in a fortnight or so I should be heading off to distant lands. I’m greatly looking forward to getting away and being able to concentrate on things to do with research for a change. I’m looking forward to the temporary change of location, not least because a warmer climate might help with my arthritis…
