Exploring the Cosmos at Maynooth

Posted in Maynooth, The Universe and Stuff with tags , , on October 4, 2023 by telescoper

Being away on sabbatical I almost forgot to post a reminder of the event I blogged about a few weeks ago at Maynooth University entitled Exploring the Cosmos. I’m told this has attracted a huge amount of interest, but the room for the event is very large and there may well be some space left.

Best wishes to everyone taking part and I hope it goes well!

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.

Barcelona Bound!

Posted in Barcelona, Biographical, Maynooth, Rugby with tags , , on September 24, 2023 by telescoper

At long last I’m ready to go. In fact I’m in the lounge at Dublin Airport Terminal 2 with plenty of time before my flight to Barcelona to sample the freebies in the Aer Lingus Business Class lounge. I spent most of the morning packing and sorting things last-minute things out. As always on such occasions I’m certain that I’ve forgotten something but I’m sure I’ll survive.

On the way through the airport I had a chat with a very friendly chap at the Fast Track security channel, about last night’s epic rugby match between South Africa and Ireland. I was fairly confident beforehand that South Africa would prove too strong for Ireland, and that’s the way it looked for the first 15 minutes, but that turned out not to be the case at the end. It’s true that the Springboks had chances to win, missing four kicks, but if you don’t take your chances at this level you can’t complain that you don’t win as a result.

The second half wasn’t pretty to watch but was in its own way very compelling. Ireland looked to have nicked it at 13-8 with a few minutes to go, but they conceded a penalty that led to a line-out close to their own try line. The resulting South African maul gathered ominously and threatened to roll forward, but stern Irish defence somehow held it up and, with the clock past 80 minutes the move faltered. With the Springboks having failed to “use it” it was inevitable that they would “lose it”. The resulting scrum was awarded to Ireland but there was no time to take it and the game was over.

It was a tense affair between two excellent teams and, although it was a low-scoring game, a marvellous piece of sporting theatre (if not for faint hearts). Watching that match was quite a way to spend my last night in Ireland for a while…

Back to the present, it’s a grey afternoon in Dublin with squally showers blowing in. With lectures starting in Maynooth tomorrow, the nights drawing in, and rainy weather on the way, I can’t say I’m sorry to be departing!

Update: my light was on time and I got safely to the hotel in which I’ll be staying until I get a longer-term arrangement sorted out. It’s a nice place and my room is spacious and comfortable. I took a couple of pictures on the flight, the first showing an interesting sunset over the clouds south of Ireland and the second a clear view down over Barcelona as we made our approach.

I was in Row 1 so got out quickly when we landed and the airport wasn’t busy so the only delay was waiting for my checked luggage to arrive. I usually travel only with cabin baggage, but I’m staying a bit too long for that this time!

P.S. Miraculously, I don’t think I have forgotten anything important!

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.

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…
