An Evening of Weird Matter at MU!

Posted in Maynooth, Talks and Reviews, The Universe and Stuff with tags , on August 28, 2023 by telescoper

With just over a week to go, I thought I’d post a reminder that Maynooth University is hosting a theoretical physics meeting early next month, from September 6th to 8th; for details see here. It has been decided that there will be a couple of public evening lectures as a double-header on the first night of the conference. One of the speakers is me. Technically I’ll be on sabbatical from September 1st but I’ve delayed my travels to allow me to ive this talk. Anyway, the advert is here:

You can join us for this “evening of science celebrating the weird and wonderful ways that matter can manifest in our universe” by getting a ticket at Eventbrite below.

Tickets are free but you do need to register in advance!

Not a Bank Holiday Monday

Posted in Biographical, Maynooth on August 28, 2023 by telescoper

So here I am, back at my desk in my office at Maynooth University. Today is a Bank Holiday in parts of the United Kingdom but not here in Ireland: we had our August Bank Holiday on the first Monday of the month rather than the last. I could say that today is a normal working day, but it’s not really because it’s been a bit busier than usual. After a few days away last week, I’ve had quite a lot to catch up, including preparing two new publications at the Open Journal of Astrophysics. I also have a Euclid telecon this afternoon, though I’m not sure how many UK participants will be there given the fact that today is a public holiday.

My sabbatical officially starts on 1st September 2023 and I’m looking forward to putting my “out-of-office” message on and (selectively) ignoring emails for a year. Although a sabbatical isn’t a holiday, I plan to take Friday September 1st off after having a few drinks on Thursday evening.

Before that I have to remove the last of my personal things from this office as it will be needed for someone else. That will give me the excuse for a big clear out of things I no longer need. This process will temporarily reduce the entropy of the room, although it will increase elsewhere I will not violate the 2nd Law of Thermodynamics.

I decided some time ago that at the end of August, I would delete my account on the platform formerly known as Twitter. Those of you that want to continue following me on social media can do so via any or all of the the following:

Euclid Update

Posted in Euclid, The Universe and Stuff with tags , , , , on August 27, 2023 by telescoper

Time for a quick update on the European Space Agency’s Euclid mission. For full details about what follows you can see here. Everything I mention here is already in the public domain, so I am not disclosing any secrets!

The last update I posted mentioned that Euclid had moved into what is called the Performance Verification phase of its mission. That has now been put on hold in order to troubleshoot an intermittent problem with the Fine Guidance Sensor (FGS) which helps to maintain correct pointing of the telescope. This issue can probably be fixed by software updates, but these will have to be tested, hence the pause. This is rather irksome, but the instrument teams are confident they can find a solution soon.

Anyway, while we’re waiting, here is a video from Launch Pad Astronomy explaining about the mission. It was actually released about six days ago but I didn’t have time to post it until now. About 15 minutes long, it’s a big longer than previous official Euclid videos I’ve posted, but I think it’s very informative:

Oh, I almost forgot to mention that I’ll be talking a little bit about Euclid among other things at this event on 6th September.

The Returning and The Leaving

Posted in Biographical, Education, mathematics, Maynooth, Politics with tags , , on August 26, 2023 by telescoper

I got back to Maynooth last night after a pleasantly uneventful train journey. Just for the record both outward and return trips were perfectly on schedule. In fact it has been a very pleasant couple of days. Congratulations to the organizers for running the meeting so well and to all the speakers for delivering such an interesting programme. Next year’s INAM will be in Galway. I’m looking forward to it already!

Anyway, now I’m back I should mentioned that the 2023 Leaving Certificate results were released to students yesterday; the first round of CAO offers will go out on Wednesday 30th. Soon after that we will find out how many students we’ll have next year. Student enrolment begins on 11th September; Orientation Week for new students starts on Monday 18th September; and lectures start the following Monday (25th). I am on sabbatical for a year from next Friday (1st September) so I won’t be teaching the new students, but I know they’ll be in capable hands.

There’s a lot of discussion – much of it poorly informed – in the media about grade inflation in the Leaving Certificate (e.g. here). This happens every year (as it does with A-levels in the UK), and its very sad that people use this occasion to publicly disparage the accomplishments of students. The students can only take the examinations that are put in front of them. Any problems with the system are not their fault at all.

This year the problem stems from a decision by Minister for Education Norma Foley to impose a condition that overall grades this year would not be lower than last year. This has led to the deployment of scaling which has resulted in an uplift of around 8%. The Higher Mathematics Leaving Certificate results also benefitted from an alteration of the marking scheme because one of the papers was deemed to be too hard. Despite this, the number of students receiving the top grade of H1 fell this year from 18% to under 11%. One might argue that this disadvantages students applying to courses that actually require mathematics compared to those that don’t.

There seems to be a widespread misunderstanding that the CAO points required for a course is somehow a measure of the level of difficulty of that course. In most cases this is not the case: having a high points threshold is basically just a way of controlling the number of students allowed in. I find the connection that has been made between grade inflation and drop-out rates extremely unconvincing. High drop-out rates in recent years are probably dominated by the pandemic, housing crisis and cost of living increases, leading to many students struggling to study effectively.

During the pandemic years, grades were inflated by including coursework rather than examinations, a change enforced because of public health restrictions. The main argument for deliberate grade inflation this year was to prevent this year’s LC students being disadvantaged with respect to last year’s. It doesn’t seem to have occurred to the Government that the same argument could be used next year, and indeed forever. Fairly typically for a politician, kicking the can down the road for the next government to deal with seems to be strategy.

As a final thought, I find myself wondering what will happen to admissions at Maynooth this year. Will the decision by The Management to scrap the promised Student Centre have a big effect? And what about the further reputational harm caused by the recent furore over the Governing Authority? I suppose we’ll find out next week!

Open Access Publishing in Astrophysics

Posted in OJAp Papers, Open Access on August 25, 2023 by telescoper

I’ve got a short talk this afternoon here at INAM about Open Access Publishing in Astrophysics so I thought I’d share the slides here. Among other things, the talk contains some updates about the Open Journal of Astrophysics.

The month of August has been rather quiet in terms of publishing at the OJAp no doubt because authors and referees have been taking vacations. When I managed to reconnect to the internet last night, though, I saw that revised versions of two manuscripts have been accepted so, depending on when the final versions hit the arXiv, I expect to publish a couple of papers early next week. That will take us to 98…

Update: mine was the last talk of the meeting and I overran a bit but I think it was reasonably well received despite that. Now I’m on a train waiting to go home.

The 2023 Irish National Astronomy Meeting

Posted in Biographical, History, mathematics with tags , , , , on August 24, 2023 by telescoper

It’s been a busy day at the Irish National Astronomy Meeting, culminating with a fascinating public lecture by journalist Seán Mac an tSíthigh – bonus marks for getting the pronunciation right – and a very enjoyable shindig involving pizza and beer. There was a strong Maynooth contribution today, with excellent talks by students Noah, Saoirse, Joe & Hannah and postdocs Lewis & John. My contribution was limited to chairing a session, though I will be giving a talk tomorrow.

The only problem today was that I couldn’t get eduroam to work on the UCC campus so have only just managed to connect after getting back to my hotel, so am a bit late posting this. Anyway, here are some snaps I took on the way this morning, on the campus including a bust of George Boole.

ps. I’m sure to blog again about the public talk, but that will have to wait until I get home at the weekend.

Go Corcaigh!

So here I am, on an intercity train to Cork from Dublin Heuston Station, en route to the 2023 Irish National Astronomy Meeting (INAM 2023).

I’ve never been to Cork before, so I’ve been looking forward to this trip. I’ve never even been in Heuston Station before, actually. A terminus that serves the West and South, it is rather like a smaller version of London Paddington. At any rate, it’s rather nicer than Connolly in that it is more spacious and has a far better selection of places to get something to eat and/or drink.

I got to Heuston on the 115 bus from Maynooth. It’s the first time I’ve been on that bus too. I’m sure to be using that service much more in the future as it’s very convenient. It’s also very quick – just 25 minutes – and the bus I got was brand new. It was full of kids when I got on, but they all got off at Liffey Valley.

Anyway, it’s not a long journey and the train, though full, is very comfortable, so I think I’ll chill and read my book and refrain from updating until we get to our destination.

UPDATE: I arrived in Cork on time and found my hotel without difficulty. It’s sunnier and warmer here than Maynooth was this morning, so I think I’ll take a walk before finding a bite to eat.

My hotel is not as awful as its name might suggest:

Maynooth University Library Cat Update

A few people have asked me about Maynooth University Library Cat (or Séamus as some people call him). I paid said feline a visit just yesterday, actually, but I could see he was busy, so I didn’t disturb him.

Deliverance at Maynooth

Just time for a quick update about the saga of Maynooth University’s Governing Authority. Today the current Governing Authority met in an emergency session. An email went around to all staff just after 7pm this afternoon from its Chair. The message begins:

Following a meeting of the Maynooth University Governing Authority (GA) today, I am writing to let you know that GA has changed its decision on the formation of the next GA to a process by which all five of the internal members will be elected by MU staff.

Thank you to Maynooth IFUT for mobilizing the academic community in Maynooth so well. And thank you to everyone who signed the petition. It just shows what can happen when you get organized. To be honest, I didn’t think GA would back down, and feared instead a full-scale industrial dispute might be looming. Fortunately, GA has seen sense and we have been spared that. However, the famous words of Churchill

We must be very careful not to assign to this deliverance the attributes of a victory.

The University can now move forward, at least until the next crisis…

Two Views of the Ring Nebula

Posted in Cardiff, Maynooth, The Universe and Stuff with tags , , , , , , , , , on August 22, 2023 by telescoper

It’s very nice to have an opportunity, courtesy of JWST, to congratulate astronomers from my current institution (Maynooth, Ireland) and my previous one (Cardiff, UK) – as well as many others – or their involvement in stunning new observations of the Ring Nebula (aka M57 and NGC 6720), a planetary nebula. There is a full story on the Maynooth University website here detailing the involvement of Dr Patrick Kavanagh in the processing of the images and another on the Cardiff University website here about Dr Roger Wesson, who led the programme. Not surprisingly there has been a lot of news coverage about these wonderful images obtained with the NIRCam and MIRI instruments on JWST here in Ireland and in Wales and elsewhere.

A particular excuse for reproducing the pictures here is to try out the fancy “image comparison” tool on WordPress, which allows the reader – that’s you – to slide one picture over the other. Have a go!

This groovy visual shows two images side by side of the Ring Nebula. The image on the left shows the NIRCam view and the image on the right shows the MIRI image. The left image shows the planetary nebula as a distorted doughnut with a rainbow of colours with a blue/green inner cavity and clear filamentary structure in the inner region. The right image shows the nebula with a red/orange central cavity with a ring structure that transitions from colours of yellow to purple/blue. Picture credits ESA/Webb, NASA, CSA, M. Barlow, N. Cox, R. Wesson

The full paper describing these observations can be found on the arXiv here.
