Trouble at Astronomy Ireland

Posted in Biographical, The Universe and Stuff with tags , , on November 5, 2025 by telescoper

I couldn’t resist passing on an unsettling news item about Astronomy Ireland, an Irish Astronomy Club described on its website in the following terms:

Astronomy Ireland is a non profit organisation and the largest national astronomy club in the world relative to population.

The news item concerned revolves around founder and chairperson David Moore (left), who has been held personally liable for multiple employment rights breaches against a former manager, Sonya Martin, at Astronomy Ireland who said she was forced to quit due to a “toxic” work environment and alleged “serious financial irregularities”.

The astronomy club and four members of its management committee, including David Moore, have been ordered to pay nearly €11,000 to the ex-employee, Sonya Martin, after she complained of constructive dismissal to the Workplace Relations Commission (WRC).

Among the allegations reported were that Mr Moore was keeping funds meant for Astronomy Ireland:

David was taking the money and pocketing it as his own income, as opposed to it going back into the society,” Ms Martin said. “The attitude changed towards myself and Ms Doyle after that,” Ms Martin said.

No doubt the money was just “resting in his account”. I mentioned this story to colleagues in the Department and none was surprised, and many (unlike myself) had known about this case for some time. I’ll keep some of the comments to myself, but one said that they gave a lecture (for free, as we academics usually do) to Astronomy Ireland which was filmed without consent. David Moore then sold DVDs of the talk. Where the profits from this went, I have no idea.

These financial shenanigans are dodgy enough but there are some truly bizarre sections of the news report. Here is one:

As the hearings continued into 2025, Mr Moore made repeated objections to being attached personally to the claim, and told Mr Dolan he had not received hearing notifications.

“Emails are unreliable,” he said. When Ms Martin’s solicitor, Mr O’Connell said the notification was sent by post too, Mr Moore said: “The post is unreliable.”

Even stranger, if not directly relevant to the case of Mr Moore, is this:

During the June 2024 hearing, Ms Martin gave evidence that Astronomy Ireland’s office landlord approached her complaining about having to clean up after the junior administrator, Mr G, who was later dismissed.

“The final straw for the landlord was that he had to clean ejaculate from the bathroom after Mr G was in there,” Ms Martin added.

Ewww…

In the interest of full disclosure, I gave a talk to Astronomy Ireland in December 2019. I don’t remember if it was filmed nor whether DVDs were sold, but given what I know now I don’t think I’ll be accepting any more speaking invitations from that organisation.

Update: it seems DVDs of my talk were made and were on sale but are no longer available. They must have sold out.

Virtually in Chile

Today has been a very busy day. I had a one-hour lecture on Partial Differential Equations from 11-12 this morning and a two-hour lecture on Ordinary Differential Equations from 2-4 this afternoon. In between those instead of having a lunch break, I was virtually in Chile giving a talk via Teams about the Open Journal of Astrophysics at LISA 10. That is not LISA as in the Laser Interferometric Space Antenna, but LISA as in Library and Information Services in Astronomy. I was invited to attend this in person, and would have gone, had it not clashed with teaching, as I have never set foot in Chile nor anywhere else in South America.

The talk went well and I had a number of questions and comments.

I got up early this morning to publish a paper taking our total so far to 399. By an unfortunate coincidence there was some problem with the integration between Crossref and our Scholastica platform so the publication didn’t go through properly. When I returned after my afternoon lectures, however, I found that whatever the problem was, it had sorted itself out; the paper is here.

The last talk I gave of this kind was May 2025, and the slides for that talk indicate that OJAp had published 293 papers so we have published over 100 papers in the 6 months since then. Unless there is another glitch tomorrow I expect we’ll reach 400 in the morning.

Denario

Posted in The Universe and Stuff with tags , , , on November 3, 2025 by telescoper

I’ve been alerted (by one of the authors) to a paper in the computer science/artificial intelligence section on arXiv, called The Denario project: Deep knowledge AI agents for scientific discovery by Francisco Villaescusa-Navarro et al. The abstract follows:

We present Denario, an AI multi-agent system designed to serve as a scientific research assistant. Denario can perform many different tasks, such as generating ideas, checking the literature, developing research plans, writing and executing code, making plots, and drafting and reviewing a scientific paper. The system has a modular architecture, allowing it to handle specific tasks, such as generating an idea, or carrying out end-to-end scientific analysis using Cmbagent as a deep-research backend. In this work, we describe in detail Denario and its modules, and illustrate its capabilities by presenting multiple AI-generated papers generated by it in many different scientific disciplines such as astrophysics, biology, biophysics, biomedical informatics, chemistry, material science, mathematical physics, medicine, neuroscience and planetary science. Denario also excels at combining ideas from different disciplines, and we illustrate this by showing a paper that applies methods from quantum physics and machine learning to astrophysical data. We report the evaluations performed on these papers by domain experts, who provided both numerical scores and review-like feedback. We then highlight the strengths, weaknesses, and limitations of the current system. Finally, we discuss the ethical implications of AI-driven research and reflect on how such technology relates to the philosophy of science. We publicly release the code at this https URL. A Denario demo can also be run directly on the web at this https URL, and the full app will be deployed on the cloud.

arXiv:2510.26887

Here’s a random picture from the paper:

I haven’t had time to read the paper yet – it’s 270 pages long – but I’m sure it will provoke strong reactions both in favour and against the idea of an AI research assistant. Comments are welcome through the box below.

P.S. The name Denario appears to be derived from the Latin “denarius”, a coin roughly equivalent to a day’s pay for a skilled worker in the days of the Roman Empire. More amusingly, “denarius” is the origin of the Polari word “dinarly”, meaning “money”. If I get time I must generate a Polari version of this manuscript.

Weekly Update from the Open Journal of Astrophysics – 01/11/2025

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , , , on November 1, 2025 by telescoper

It’s time once again for the usual Saturday update of the week’s new papers at the Open Journal of Astrophysics (although a bit later in the day than usual). Since the last update we have published another two papers, which brings the number in Volume 8 (2025) up to 163, and the total so far published by OJAp up to 398.

The first paper this week is “Instability and vertical eccentricity variation in global hydrodynamic disk simulations” by Janosz W Dewberry (U. Mass. Amherst, USA), Henrik N. Latter and Gordon I. Ogilvie (U. Cambridge, UK) and Sebastien Fromang (U. Paris Saclay, France). This article was published in the folder Solar and Stellar Astrophysics on Tuesday 28th October 2025; it discusses the instabilities and eccentricity variations generated in numerical hydrodynamic simulations of accretion disks.

The second (and last) paper of the week is “Fast X-ray Transient Detection with AXIS: application to Magnetar Giant Flares” by Michela Negro (Louisiana State University, USA) and 8 others based in the USA and Canada. This one was also published on Tuesday 28th October, but in the folder High-Energy Astrophysical Phenomena. It presents a feasibility study of detecting Magnetar Giant Flares with the Advanced X-ray Imaging Satellite (AXIS). The overlay is here:

It being a relatively slow week we didn’t reach the 400 mark as I thought we might, but we will probably get there next week. After 10 months of the year 2025, in which we have published 163 papers, a rough projection for the 2025 total is 195. We do have some extra papers up our sleeve, however, so we might well reach 200 for the year. We will find out soon enough!

Oíche Shamhna shona daoibh go léir!

So we have arrived at October 31st, Hallowe’en or, in pagan terms, Samhain. This, a cross-quarter day – roughly halfway between the Autumnal Equinox and the Winter Solstice – represents the start of winter (“the dark half of the year“) in the Celtic calendar. Technically, Samhain is tomorrow, 1st November, but the Celtic practice of reckoning days from sunset to sunset makes this a moot point.

Samhain is pronounced something like “sowin”, with the “sow” as in a female pig. The h after the m denotes lenition of the consonant (which in older forms of Irish would have been denoted by a dot on top of the m) so, when followed by a broad vowel the m is pronounced like the English “w”; when followed by a slender vowel or none “mh” is pronounced “v” or in other words like the German “w” (which makes it easier to remember). The phrase Oíche Shamhna (the Eve of Samhain) is used for Hallowe’en; it contains the genitive form of Samhain.

Unfortunately I’m still struggling a bit with the after-effects of yesterday’s jab so have neither the time nor the energy for a long post today so instead, before I go for another nap, I’ll just share a a replica (from the National Museum) of an authentically carved turnip as was traditional in old times. I think it’s infinitely scarier than any of those namby-pamby pumpkins.

This one is even scarier!

Fifth Covid Booster

Posted in Biographical, Covid-19 with tags , , on October 30, 2025 by telescoper

Just for the record, today I had my 5th Covid-19 vaccination booster. As an Old, I get prompted by the HSE to get free Covid-19 boosters and winter ‘flu jabs so I booked an appointment at a local pharmacist as I did last year. In fact I went into work this morning to say farewell to newly-doctored Aoibhinn Gallagher, and walked to the pharmacy afterwards. I didn’t have to wait long and the vaccination itself only took a matter of minutes.

That makes seven Covid-19 jabs altogether for me: the initial vaccination was in two stages, and I have since had five boosters. All but one of these have been Pfizer; the other was Moderna.

On previous occasions of this type I’ve usually managed to arrange an afternoon free afterwards in case of any adverse reactions. That was easy this time because it is Study Week at Maynooth University so there are no lectures. I did feel a bit tired after the jab, and had a short nap this afternoon. I also seem to have developed a runny nose, which may or may not be a reaction to the injection, but I don’t think it’s very serious.

Update: 24 hours on, I’m still feeling the after-effects. Hopefully, I’ll be better by the weekend.

After Conferring

Yesterday I attended a conferring ceremony at Maynooth which was a very special occasion because it involved the formal award of the PhD degree to Aoibhinn Gallagher whom I supervised. Two other research students from the Department of Physics got their PhDs yesterday too; Matthew Birney and Hannah O’Brennan. Matthew (ESO Garching) and Aoibhinn (Bielefeld) both now have postdoctoral positions in Germany, incidentally.

These events are not actually called Graduation Ceremonies here in Ireland but Conferring Ceremonies. I was impressed that the local suppliers of academic dress, Phelan Conan were able to supply the correct 1989 vintage DPhil gown from Sussex University as opposed to the less interesting modern one. I would have worn it for the picture above, but by the time we found Hannah to take the photo I had already returned it to the supplier. Here are two more with myself in the gown and mortarboard:

You can see a picture of me wearing the same sort of gown in Brighton back in 1989, when I was a skinny young queen, here. I’ll add more pictures from yesterday if and when I get them.

As well as the PhDs we also saw the entire class of our MSc in Theoretical Physics and Mathematics get their degrees. I haven’t got any photographs of them, but will add any that I find. Here is a photograph of them outside the TSI building, courtesy of Jonivar Skullerud.

After the ceremony, those who got their degrees went for dinner with their respective parents, siblings and others who had come to attend the ceremony. We did meet up later on, however, in a local pub for a drink or several. In among all that I didn’t have time to write a post, bringing to an end a blogging streak of 109 days.

Graduation ceremonies are funny things. With all their costumes and weird traditions, they even seem a bit absurd. On the other hand, even in these modern times, we live with all kinds of rituals and I don’t see why we shouldn’t celebrate academic achievement in this way.

I like graduation ceremonies, actually. As each person walks across to be presented with their scroll you realize that every one of them has a unique story to tell and a whole universe of possibilities in front of them. How their lives will unfold no-one can tell, but it’s a privilege to be there for one important milestone on their journey, even those from other departments with whom you have had no contact at all.

I always find these ceremonies bittersweet occasions, though. There’s joy and celebration, of course, but these are tempered by the realization that many of the young people whom you’ve seen around long enough to grow accustomed to their faces, will disappear into the big wide world, in some cases never to be seen again. Although everyone is rightly proud of the achievement – either their own in the case of the graduands or that of others in the case of the guests – there’s also a bit of sadness to go with the goodbyes. It always seems that as a lecturer you are only just getting to know students by the time they graduate, but that’s enough to miss them when they go.

Anyway, all this is a roundabout way of saying congratulations once more to everyone who graduated yesterday, including Matthew, Hannah and Aoibhinn, and I wish you all the very best for the future!

On the Evidence for Supersymmetry from CMS…

Posted in The Universe and Stuff with tags , , , , on October 27, 2025 by telescoper

Every now and again I look at the latest particle physics literature on arXiv to see what’s going on. The other day I saw a preprint there which gives a review of the latest results on supersymmetry from the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider at CERN. I should explain that, in experimental particle physics, “compact” means “fucking enormous”.

Anyway, the abstract of the paper reads:

The Run 2 data-taking period of the CERN Large Hadron Collider during years 2015-2018 provided about 140 fb-1 of proton-proton collisions at 13 TeV, offering an unprecedented opportunity to explore supersymmetry (SUSY) across a wide range of experimental signatures. CMS responded with a broad and diverse search program, carrying out dozens of analyses that probed a multitude of final states and systematically explored different regions of the SUSY parameter space. No significant deviations from standard model predictions were observed, and the results were used for constraining the SUSY landscape. In this review, I provide a comprehensive account of the CMS Run 2 SUSY program, covering its strategy, targeted models, and analysis methods. I then present the full set of searches and conclude with their combined impact through simplified model and phenomenological MSSM interpretations.

arXiv:2510.17971

Here is one of the pretty pictures from the review. This one shows the constraints on the masses of any supersymmetric counterparts of the electroweak gauge bosons.

To summarize the evidence for supersymmetry from CMS, there is none, nil, nought, nada, zero, zilch, zip, sweet Fanny Adams, bugger-all and diddly-squat. I hope this clarifies the situation.

It’s That Time Again

It’s Sunday 26th October 2025 and in the early hours of this morning the clocks went back, bidding goodbye to Summer Time. You can tell I’m an oldie because I have quite a lot of time-keeping devices around the house that need to be set by hand. My computer updates itself, of course, but I’m not sure if WordPress does. I’ll find out when I publish this post!

I’ve written before about the silly business of moving the clocks backwards and forwards (e.g. here) so I won’t repeat it all again. I will mention, however, that some time ago, before the Covid-19 Pandemic, the European Parliament approved a directive that would abolish `Daylight Saving Time’.  Unfortunately that plan was ‘paused’ although Spain is apparently going to try to get it going again.  I’ve long felt that the annual ritual of putting the clocks forward in the Spring and back again in the Autumn was a waste of time effort, so I’ll be glad if and when this silly practice is terminated. It would be far better in my view to stick with a single Mean Time throughout the year. I’m disappointed that this hasn’t already happened.

Anyway, talking of time, we have now completed five weeks of teaching in Semester 1 at Maynooth University. Tomorrow (Monday 27th October) is the October Bank Holiday and next week is Study Week so there are no lectures or tutorials. We do, however, have conferring (graduation) ceremonies including one that involves my recently-completed PhD student. Looking at my diary I notice also that I also have an appointment for my flu jab and Covid-19 booster, another sign that I’m an old codger.

Normally Study Break comes halfway through the 12-week teaching term but this year it splits 5-7. It did so last year too, actually. I am not unhappy to have an earlier break as I’m very tired, but I am conscious that this is going to make for a longer run-in to the Christmas holiday. We are supposed to teach up until Friday 19th December, but I don’t have any lectures on that day.

I’m not sure how much studying the students do during Study Week, but it’s not a holiday for academic staff even though there is no undergraduate teaching. Among other things we have examinations to write for the January examination period, which must be checked and printed well in advance. The deadline for these is November 3rd, so I have all week but I am planning to spend next weekend elsewhere so I need to get them done beforehand.
