General Science at Maynooth

Posted in Education, Maynooth with tags , , , , , , , on May 27, 2024 by telescoper

Following on – sort of – from yesterday’s post – here is a little promotional video about the ‘Omnibus’ Bachelor of Science undergraduate course (codename MH201). I have blogged about this course before (e.g. here) but this gives me an opportunity to repeat the salient points.

Currently, most students doing Science subjects here in Maynooth enter on the General Science programme a four-year Omnibus BSc course that involves doing four subjects in the first year, but becoming increasingly specialized thereafter. That’s not unlike the Natural Sciences course I did at Cambridge, except that students at Maynooth can do both Mathematical Physics and Experimental Physics in the first year as separate choices. I’d recommend anyone who wants to do Physics in the long run to do both of these, as they do complement each other. Other possibilities include Chemistry, Computer Science, Biology, etc.

In Year 1 students do four subjects (one of which has to be Mathematics). That is narrowed down to three in Year 2 and two in Year 3. In their final year, students can stick with two subjects for a Joint Honours (Double Major) degree, or specialise in one, for Single Honours.

I like this programme very much because it does not force the students to choose a specialism before they have had a taste of the subject, and that it is flexible enough to accommodate Joint Honours qualifications in, e.g., Theoretical Physics and Mathematics. It also allows us to enrol students onto Physics degrees who have not done Physics or Applied Mathematics as part of the Leaving Certificate.

Anyway, this video features Oisín Davey, who took Mathematical Physics, Experimental Physics, Chemistry and Mathematics in his first year. As a matter of fact I taught him in Year 1 (Mechanics & Special Relativity) and Year 2 (Vector Calculus and Fourier Series) but, despite that, as he explains, he has decided to persist with Mathematical Physics. He will be in the final year next academic year, after he returns from his summer in CERN, and I’ll be back from sabbatical.

Maynooth University Library Cat Update

Posted in Maynooth with tags on May 25, 2024 by telescoper

I thought I’d share this image of Maynooth University Library Cat, complete with daisy bonnet. He doesn’t look entirely gruntled with his new headgear, and I’m not sure how long it stayed on his bonce, but it’s nice to see him in fine fettle, though he’s getting a few more grey hairs. Aren’t we all?

Euclid Paper Day!

Posted in Barcelona, Euclid, Maynooth, The Universe and Stuff with tags , , , , , , , , on May 24, 2024 by telescoper

This morning’s arXiv update brought the expected deluge of preprints from Euclid. You can find details of all fifteen of the new articles here. Ten of them relate to the Early Release Observations of which five were announced yesterday and five last November. These are essentially byproducts of the testing and calibration phase of the Euclid mission rather than the main cosmological survey. ESA is making a series of short videos about these results which I will share on here from time to time.

Of more direct relevance to cosmologists such as myself are the following five reference papers:

The overview paper, led by Yannick Mellier (Euclid Consortium Lead), giving a general description of the mission capabilities and science goals, will be the main reference paper and just about every active member of the Euclid Consortium is on the author list (including myself). That’s over a thousand people, not quite at the level of the Large Hadron Collider but getting there. I do think we need to find a better way of giving credit to work in large collaborations than through authorship, but until someone comes up with a workable scheme, and people responsible for hiring researchers adopt it, we’re stuck with what we’ve got. At least I can say that I’ve read that paper (which is 94 pages long, including the author list)

Papers II-IV are technical articles relating to Euclid’s instruments and their calibration, which will also be important references for the survey part of the Euclid mission. Paper V is about the Flagship simulations and the mock catalogues produced therefrom; I discussed these a while ago here. It is led by Francisco Castander of Institut de Ciencies de l’Espai, who organized the meeting I attended recently here in Barcelona.

These papers now now be peer-reviewed and, assuming they are accepted, published in a special issue of Astronomy & Astrophysics (A&A).

New Results from Euclid

Posted in Euclid, Maynooth, The Universe and Stuff with tags , , , , on May 23, 2024 by telescoper

As it was foretold, exciting new results from the European Space Agency’s Euclid mission have now been released.

You can read more about these images here.

Together with the five images released last November that makes a total of ten Early Release Observations from the pre-survey phase of Euclid. It’s not all about the pictures, however. Today also saw the release of ten scientific papers to go with these images, as well as five reference papers for the main survey. You can find them all, with accompanying information here. They will be announced on arXiv tomorrow.

You might also be interested to read my Euclid piece on RTÉ Brainstorm which has just appeared. This is not just about the new images, but gives an update on what Euclid has been up to since launch, and what we can expect in the future. There’s also a version adapted for Maynooth University PR purposes here. It includes this quote:

Today’s release of new data and technical papers from Euclid is exciting in itself but also marks the start, after months of painstaking calibration and testing of the instruments, of Euclid’s main cosmological survey. We are on the threshold of a new era in cosmology. Maynooth is the only University in Ireland to be involved in this mission and it is very exciting to be at the forefront of such an important scientific development.

I’m also quoted in a piece in the Irish Times. You’ll probably find the article blocked by a paywall but my bit is:

Gearing up for Thursday’s Euclid News

Posted in Euclid, Maynooth, The Universe and Stuff with tags , , , , , , , on May 21, 2024 by telescoper

It’s a hectic time ahead of a Big Event on Thursday 23rd May, which will include the publication of five new Early Release Observations (EROs). I’m not at liberty to say what they are until after 12 noon (CEST) on Thursday except that they’re very pretty. You can watch the live stream here:

Including the five released on November 7th 2023 that will bring the total to ten. All the ERO pictures will be available on the ESA archive here.

Thursday will also see the release of ten scientific papers related to the EROs; they will appear on arXiv on Friday 24th May. These will be the first science results from the Euclid mission.

But that’s not all! Thursday will also see the publication of five papers from the Euclid Consortium (of which I am the sole member based in Ireland). These will be the principal technical reference papers aimed at the astronomical community about the Euclid mission, covering the instruments, cosmology and other astronomy science possibilities, as well as the cosmological simulations used to assist the analysis of the mission. One of these, the main overview paper for the mission, has over a thousand authors (one of whom is your truly).

Thursday’s announcements are likely to significant level of press interest. That’s not only due to the European Space Agency’s own social media feeds and the like, but also local activities in Ireland. For example, there’s this from Science Foundation Ireland using this, from the Little Book of Irish Research:

I have also written a piece for RTÉ Brainstorm, as a kind of update on the one I wrote last year on the occasion of the launch; this will go live after the embargo is lifted on Thursday.

The Week(s) Ahead

Posted in Barcelona, Biographical, Euclid, Maynooth with tags , , , , on May 20, 2024 by telescoper

Today is a public holiday in Spain, as it is in much of Europe (including France, Germany, The Netherlands and Denmark). The occasion for the day off is Pentecost (or Whitsuntide as it is known in the UK) which, if I understand correctly, is when the Holy Spirit went down on the Apostles. Actually Pentecost (Whit Sunday) was yesterday, exactly 7 weeks after Easter Sunday, which was quite early this year which is why Pentecost Monday (20th May) is earlier than the fixed Bank Holidays used to mark it in the UK (the last Monday in May, 27th, next Monday) and Ireland (the first Monday of June, 3rd, in two weeks’ time). Could I perhaps take all three off?

Today’s holiday notwithstanding, this is going to be a busy week. On Wednesday and Thursday there is to be an event at the European Space Agency coincident with which, on Thursday 23rd May, there will be a significant press event relating to Euclid. I’m not at liberty to say any more at this point, as everything is strictly embargoed until 12 noon CEST on that day, but I have been writing a piece for RTÉ Brainstorm to come out as soon as the embargo is lifted. Hopefully the Communications team at Maynooth University will get involved in the press activity. Watch this space.

Remarkably for me, I filed the RTÉ Brainstorm piece ahead of the deadline but it’s no time to rest on my laurels because I have another paper to finish this week by a different deadline.

And next week will be busy too. I have to make a short trip to not-Barcelona to do a PhD examination in Newcastle upon Tyne and give a lecture in Oxford, where (so I’m told) there is a University of some sort. Then I have to pass through Maynooth to vote in the Local and European Elections before returning to Barcelona. Having another two Whit Monday holidays is looking like a good plan…

Examination Time in Maynooth

Posted in Barcelona, Education, Maynooth, The Universe and Stuff with tags , , on May 17, 2024 by telescoper

Today ( Friday 17th May) is the first day of the Summer Examination Period in Maynooth. Although I’m not there right now I thought I’d take the opportunity to wish all students the best for their examinations:

You shouldn’t really be relying on luck of course, so here are some tips for the examination period (especially for physics students, but applicable elsewhere).

  1. Try to get a good night’s sleep before the examination and arrive in plenty of time before the start. Spending all night cramming is unlikely to help you do well.
  2. Prepare well in advance so you’re relaxed when the time comes.
  3. Read the entire paper before starting to answer any questions. In particular, make sure you are aware of any supplementary information, formulae, etc, given in the rubric or at the end.
  4. Start off by tackling the question you are most confident about answering, even if it’s not Question 1. This will help settle any nerves. You’re under no obligation to answer the questions in the order they are asked.
  5. Don’t rush! Students often lose marks by making careless errors. In particular, check all your numerical results on your calculator at least twice
  6. Please remember the units!
  7. Don’t panic! You’re not expected to answer everything perfectly. A first-class mark is anything over 70%, so don’t worry if there are bits you can’t do. If you get stuck on a part of a question, don’t waste too much time on it (especially if it’s just a few marks). Just leave it and move on. You can always come back to it later if you have time.

Meanwhile, in Barcelona, Monday is a public holiday (Pentecost) so I am faced with the prospect of having to endure a long weekend break. Such is life…

Night of the Aurora

Posted in Biographical, Maynooth, The Universe and Stuff with tags , , , , , on May 11, 2024 by telescoper

My social media feeds have been buzzing all day with images of last night’s display of the Aurora Borealis (and Australis) resulting from a large solar storm. I saw some great pictures from Ireland, including many from Maynooth and environs. I really liked this one taken from one of the ships of the Irish Naval Service:

I also saw pictures of the Aurora Borealis from the UK (even as far South as the Midlands), USA and as far South in Europe as Marseilles, not to mention New Zealand (Aurora Australis).

It’s not that unusual for the Northern Lights to be visible from Ireland, but it is extremely rare to see them from Catalonia. They were visible last night from Sabadell, just a few km North of Barcelona, though not as far as I know in Barcelona itself. I didn’t see anything, but I was otherwise engaged. The Observatory at Montsec Astronomical Park recorded the strongest level of Auroral activity for 150 years.

All this reminds me that many moons ago, I once stood directly under an auroral display, in Tromsø (Norway), and I can tell you ever the word “awesome” applied to anything, this was it. The curious thing is that I had the definite feeling that there was a booming and whooshing sound to go with the light show. I wasn’t the only one there who thought they could hear it as well as see it. And I wasn’t drunk either. Well, not very.

Whenever I asked anyone about the sound my questions were dismissed on the grounds that there is no physical mechanism that could produce sound waves at audible frequencies of sufficient power to reach ground level from the altitude at which the light is generated. It must have been psychological, as if the brain wants to add a backing track when it sees something as spectacular as this. However, read at least one researcher is not so sure…

Maynooth University Library Cat Video Update

Posted in Biographical, Maynooth with tags , on May 10, 2024 by telescoper

For those of you who can’t get enough Maynooth University Library Cat action, I thought I’d share this instagram post that features a short documentary film made by some students about said feline:

The video is also available on Youtube:

Incidentally, Fiona Morley (who you see interviewed in the video) is Head of Digital Programmes and Information Systems at Maynooth University and, with her team, has given huge support to the Open Journal of Astrophysics.

This reminds me that today is the last day of teaching at Maynooth. There will be a short break until examinations begin a week today. This means that, although my sabbatical continues until the end of August, I won’t be missing any more lectures from today. I won’t be marking examinations either, but it is a reminder that it’s not that long until I have to resume such duties.

Maynooth University Library Cat Update

Posted in Maynooth with tags , on May 2, 2024 by telescoper

Quite a few people have asked for an update about Maynooth University Library Cat. I’m not actually in Maynooth right now so can’t pass on first-hand knowledge, but I am informed that said feline is doing fine and yesterday a colleague sent me this picture.

To be honest he looks a bit peeved* that his dish is empty. It is entirely possible, however, that he had been fed several times already before that picture was taken…

*In Irish, the word “peeve” is pronounced “piamh”
