The Euclid spacecraft launched over a week ago so so here’s a short video explaining its trajectory and what it will do over the next weeks and months.
Euclid Update

Posted in Biographical, Covid-19 with tags Covid-19, National Astronomy Meeting, SARS-COV-2 on July 9, 2023 by telescoperPublic Service Announcement!
Last week’s UK National Astronomy Meeting in Cardiff was the biggest ever, and it was noticeable that very few people (less than 5%) were wearing face coverings at any point. It’s not surprising therefore that there have been reports of people testing positive for Covid-19. I don’t know how many cases have developed overall, but two people with whom I was in reasonably close contact during the conference have tested positive so, although I have no symptoms, I decided to test myself as a precaution.
Doing a test was more difficult than I thought as antigen test kits are in short supply in Maynooth these days. I tried two supermarkets and a pharmacist to no avail, and then someone in the pharmacist said she’d seen them in Aldi so I bought some there.
The result was negative:
I’ll do another one tomorrow morning just in case.
If you happened to be at NAM I’d encourage you also to get a test. If you have done one already and tested positive I’d encourage you to contact the Local Organizing Committee, who are monitoring the situation, either by email (contact details here) or via the anonymous reporting form here.
Branding Physics
Posted in Maynooth with tags Artificial Intelligence, theoretical physics on July 9, 2023 by telescoper
How do you like the AI-generated image for new corporate branding of the Department of Theoretical Physics at Maynooth University?
I quite like it, as it accurately portrays the friendly and welcoming atmosphere of the Department, but it’s a bit misleading because the sinister-looking men in the picture are wearing ties.
Back to Maynooth
Posted in Biographical, Cardiff, GAA, Maynooth with tags astronomy, Cardiff Airport, Chart, Maynooth on July 8, 2023 by telescoperI made it back to Maynooth from Cardiff last night after a relatively uneventful journey, although sitting next to a hen party on a RyanAir flight en route to Dublin wasn’t exactly the most peaceful experience and I was quite tired when I got home.
Among the many things that have changed over the last few years is how much quieter Cardiff Airport is. When I arrived there at about 6pm yesterday there were only two flights on the departure screen. One of them (a KLM flight to Amsterdam) was then cancelled, so all the intending passengers had to leave the departure lounge and collect their checked luggage. My flight was on time, however, and was very full.
In a previous pre-pandemic existence I spent half my time in Cardiff and half in Maynooth so had to cross the Irish Sea twice a week. The airline I used in those days, FlyBe, went bust just before the pandemic. RyanAir has taken the Cardiff-Dublin route, deploying a Boeing which is much bigger than the Embraer used by FlyBe, but there is only one flight a day. The other routes previously operated by FlyBe from Cardiff (e.g. to Edinburgh) no longer exist. Bristol is relatively easy to get to from Cardiff so I suppose people go that way nowadays if they have to fly.
A consequence of the small number of flights from Cardiff Airport is that the shuttle bus to Cardiff City Centre no longer runs. That was the method I used to get to and from the airport in my previous existence when I had to cross the Irish Sea twice a week. That no longer being available, I travelled to the airport by train and bus transfer. It’s a lot less convenient than the old bus, and a bit more expensive, but went off without any hitches.
Anyway, it’s nice to be home. I plan to spend the day chilling and watching the hurling semi-final between Limerick and Galway. UPDATE: Defending Champions Limerick beat Galway by 2-24 to 1-18 and thus get to the final yet again. The other semi-final, between Clare and Kilkenny, is tomorrow.
P.S. I forgot to mention that the good folk of Cardiff gave me a mug advertising CHART – Cardiff Hub for Astrophysics Research and Technology – which is new since my day.
NAM Ending
Posted in Biographical, Cardiff on July 7, 2023 by telescoperSo here I am, getting ready to check out of my hotel and head off to the last day of the UK National Astronomy Meeting 2023.

I had to miss out on yesterday afternoon’s sessions to deal with some personal matters, all thankfully resolved, though that had the bonus of having to take a walk through Bute Park and get some lovely fresh air. I managed to sort out the things I needed to do, but it took longer than I thought it would for various reasons. Anyway, there is still the best part of a day to go, and my flight back to Dublin is not until this evening, so I’ll be attending most of the day’s session.
Since I did my talk on Wednesday I’ve been a free agent and while I have been at the meeting I have been moving from session. It’s been good to catch up with what’s going on across the field. I went to sessions on infrared astronomy and gravitational waves as well as a number on cosmology (including one on the UK contribution to Euclid).
I think the meeting has been excellent and I congratulate the organizers and all the contributors for putting on such a great programme. It’s great to see Cardiff at the forefront of so many great things going on UK Astronomy.
P.S. This may have been the biggest NAM ever..

Brainstorm Flash
Posted in Biographical, Euclid, Maynooth, The Universe and Stuff on July 6, 2023 by telescoperThe media activity surrounding the launch of Euclid on Saturday continues. Yesterday a piece by yours truly appeared on RTÉ Brainstorm with the title All you need to know about Euclid’s six year space mission. It subsequently got picked up by the main RTÉ News website on their News Lens panel, although it’s in second place after a story about a hot-dog eating competition:

P.S. There is also piece in siliconrepublic based on an interview with me here.
Opening the National Astronomy Meeting
Posted in Cardiff, Politics, The Universe and Stuff with tags Cardiff, Centre for Student Life, Mark Drakeford, National Astronomy Meeting 2023 on July 3, 2023 by telescoperMy first impressions of Cardiff after arriving yesterday is that a lot of things have changed. That sadly includes the fact that a number of my favourite places in the city centre have closed. On the other hand, some thing have improved. The Centre for Student Life, for example, is completely new since my days here and is a definite improvement on the previous dingy premises. It also just happens to be where the plenary sessions of the 2023 National Astronomy Meeting are being held:


The first plenary session of the week was opened by the First Minister of Wales, Mark Drakeford, who gave very a nice speech, in which he spoke very knowledgeably of the inspirational nature of astronomy as well as the history of the subject in Wales. It was a very impressive start to the week!
The Vice-chancellor of Cardiff University, Colin Riordan, was also there.
To Cardiff
Posted in Biographical, Cardiff, The Universe and Stuff on July 2, 2023 by telescoper
So I’m here in sunny Cardiff for the UK National Astronomy Meeting which is taking place here from tomorrow 3rd July until Friday 7th July. I’m here all week!
On my way here this morning, in Dublin Airport, I picked up a copy of the Sunday Times Ireland edition to find this:

It’s not a bad piece except I’m uncomfortable about being in the same subheading as Elon Musk! More amusingly still, my piece is next to a story about how your sex life needn’t stop when you reach 50. I wish someone had told me that 10 years ago!
