I thought I’d share a couple of little clips I took on my visit to the Fundació Joan Miró last week, one is a few of and from the rooftop, which is dotted with various sculptures, and the other is a fascinating mercury fountain created by Alexander Calder. And don’t worry, it’s enclosed in a glass case!

Posted in Biographical, Euclid, Harassment Bullying etc with tags ECDC, Equality and Diversity, Euclid, Euclid Consortium, Euclid Consortium Diversity Committee on July 2, 2024 by telescoperIt was officially announced at last year’s Euclid Consortium Meeting in Copenhagen that I had been appointed to the role of Chair of the Euclid Consortium Diversity Committee (ECDC). Following the tradition, a similar announcement was made at the Rome meeting this year that from 1st July there would be a new Chair in the form of Helmut Dannerbauer, who is based at the Instituto de Astrofísicas de Canarias on Tenerife. There are still a few loose ends to tie up, not helped by my computer problems, but I’m gradually winding up my activity on the ECDC and handing things over to Helmut.
As I pointed out in my post last year, I was in the final year of my stint on the ECDC when I was made Chair so it was always envisaged that I would serve for only one year. I only agreed to do it, in fact, because I had my sabbatical coming up. I definitely wouldn’t have been able to do the job alongside a full teaching and other workload and didn’t even consider continuing after my sabbatical was over.
Instead of trying to describe the role and activities of the ECDC generally, I will direct you to the information given on the brand new Euclid Consortium website which is a one-stop shop for everything to do with Euclid. You can find specific information about Equity, Diversity and Conduct there and/or on the ECDC’s own public website here from which I’ve taken a screengrab of the nice banner:
Just for information, the Euclid Consortium has about 2600 members so it really is a very large organization. It is also very international, with many people working in countries they were not born in and whose language is not their first. It is the aim of the ECDC to encourage a positive and inclusive environment within it for the benefit of everyone in it. The diversity in Euclid has many dimensions, including gender, nationality, ethnicity, and career stage as well as type of work; Euclid comprises specialists in instrumentation, software engineering, observational astronomy and theory to name but a few. The aim of the ECDC is to try to make sure everyone can work together in an inclusive environment.
It has been good to see over the few years some policies have been implemented to allow a greater diversity among leadership roles in the Euclid Consortium, especially by having a planned programme of rotating chairs and coordinators. I think this and other inititiatives are making a difference.
Euclid was launched a year ago yesterday, and the past twelve months have involved a huge amount of hard work by everyone concerned and not a little tension in some parts. The stress will continue as we head towards DR1, the first main Data Release, in 2026. The Euclid Consortium has a Code of Conduct to remind members to behave professionally towards their fellow workers at all times.
I’d like to wish all the new members of the ECDC, and those continuing, all the best in the future. I’d also like to extend personal thanks to those members who are leaving this year, especially Marc, Florence and Chiara. We have had regular telecons virtually every fortnight for the last year and I’ve enjoyed everyone’s contribution to the discussions.
Two More Euclid ERO videos
Posted in Euclid, Football with tags ESA, Euclid, Euclid Early Release Observations, Gravitational Lensing, Perseus Cluster on July 1, 2024 by telescoperI’ve been a bit busy catching up on things since my departure from Barcelona with the result that I almost forgot to post anything today. Fortunately there are two more Euclid Early Release Observations I can share to fill the gap. They’re about 4 minutes apiece, so there’ll be plenty time to watch them while waiting for the VAR operators to make an offside decision during the next European Championship match…
The first is entitled Measuring Luminosity Function for the Perseus Cluster of Galaxies using Euclid ERO data:
The article describing this work can be found on arXiv here; it perhaps makes up for the missing article in the title of the video.
The second one is this, about gravitational lensing and the search for high-redshift galaxies:
The paper for this one can be found on arXiv here.
Como si fuera esta noche la última vez
Posted in Barcelona, LGBTQ+ with tags Barcelona, La Rambla, Pride on June 29, 2024 by telescoperThis afternoon, it being my last full day here, I decided to make a farewell tour of Barcelona. I shall miss this place, as the streets have become quite familiar. Two things I won’t miss are the crowds of tourists in some quarters and the heat – it was 28° C at 6pm.
Anyway, my walk included a last ramble up La Rambla from the old harbour towards my flat. I thought it looked unusually quiet when I started, but then realized there was a big crowd at the top end (where it joins Plaça de Catalunya). Pride month in Barcelona started yesterday (28th June, LGBT Pride Day, the anniversary of the start of the Stonewall Riots) and goes on for about a month. This demonstration was a kind of counter to the “official” Barcelona Pride events, a protest against excessive commercialization, pinkwashing, homophobic and transphobic violence, among other things. Pride is, and should be, a protest.
New Publication at the Open Journal of Astrophysics
Posted in OJAp Papers, Open Access, The Universe and Stuff with tags arXiv:2402.13912v2, Cosmology and NonGalactic Astrophysics, Gravitational Lensing, mass reconstruction, Minkowski Functionals, The Open Journal of Astrophysics on June 29, 2024 by telescoperIt’s a rainy Saturday morning here in Barcelona, and here’s the last update from the Open Journal of Astrophysics before I depart these shores. In fact there is only one paper to report this week, being the 52nd paper in Volume 7 (2024) and the 167th altogether. It was published on June 24th 2024. With six months of the year now over, I predict we will have published about 52×12/6=104 papers by the end of the year.
The title is “Comparing Mass Mapping Reconstruction Methods with Minkowski Functionals” and it is in the folder marked Cosmology and NonGalactic Astrophysics. The authors are: Nisha Grewal (U. Edinburgh, UK), Joe Zuntz (U. Edinburgh, UK) and Tilman Tröster (ETH Zurich, Switzerland); the paper is about quantifying the accuracy, precision and efficiency of lensing reconstruction methods using topological characteristics known as Minkowski Fuctionals.
Here is the overlay of the paper containing the abstract:
You can click on the image of the overlay to make it larger should you wish to do so. You can also find the officially accepted version of the paper on the arXiv here.
P.S. Since I only had the one paper to publicize this week I took a few minutes to add the overlays to last week’s post, which I couldn’t do at the time because of computer problems.
Fundació Joan Miró
Posted in Art, Barcelona with tags Fundació Joan Miró, Joan Miró, Parc de Montjuïc on June 28, 2024 by telescoper
My time in Barcelona is rapidly drawing to a close so I thought I’d spend the morning visiting the Fundació Joan Miró, which is situated in the Parc de Montjuïc with excellent views of the City. Quite apart from the strange and wonderful collection of things inside, it’s just a beautiful space to wander around; there’s a sense of light and space which is very refreshing. It took no longer than 30 minutes to reach it from my apartment, via the Metro L3 and the funicular railway from Parallel which takes you within 5 minutes’ walk of the building.
As well as the permanent collection of works by Joan Miró, there are pieces that influenced his development as an artist, such as the 14th Century altarpiece shown above: in his early years, Miró experimented with the very flat perspective often deployed in mediaeval art. The exhibition includes a large range of materials, including sailcloth and wool as well as the more usual oil and canvas; there’s also a mercury fountain. There is also a temporary exhibition by Vietnamese sculptor Tuan Andrew Nguyen whose creations include dynamic shapes evoking explosions made from fragments of unexploded bombs found in his homeland in the aftermath of the Vietnam war.
Recent Citations in Astrophysics
Posted in Open Access with tags A&A, ApJ, Astronomy and Astrophysics, Astrophysical Journal, citations, Monthly Notices of the Royal Astronomical Society, OJAp, The Open Journal of Astrophysics on June 27, 2024 by telescoperWhen I was on the train yesterday I thought I’d pass the time by looking up some numbers to answer a question someone asked me after my seminar in Valencia. I thought the results were Quite Interesting so I thought I would share them here. Just for fun I worked out the average number of citations so far for all papers published in 2023 in the “leading” astrophysics journals:
| Journal | Mean citations per paper | Median citations per paper |
| ApJ | 6.2 | 3 |
| MNRAS | 6.9 | 4 |
| A&A | 7.7 | 4 |
| OJAp | 8.4 | 5 |
I suspect these numbers don’t turn out the way most people would have imagined! I don’t think you should infer too much from these figures because the window for citations is very narrow, but they do demonstrate that there’s no evidence that papers in the Open Journal of Astrophysics attract any less attention than those in more mainstream journals.
A Time Out in Cosmology
Posted in Biographical, LGBTQ+, Talks and Reviews, The Universe and Stuff with tags Oxford University, Pride on June 26, 2024 by telescoperRegular readers of this blog – both of them – may recall that earlier this month I gave the inaugural Pride Lecture in the Physics Department at Oxford University. That lecture was given in person but also streamed via Zoom. This is just an update to let you know that a recording of that stream is now available here should you wish to view it:
From Valencia
Posted in Biographical, Books, Talks and Reviews, Open Access on June 26, 2024 by telescoper
Here I am, on the train from Valencia back to Barcelona. I’ve been to Valencia many times but the last time was so long ago that I don’t remember when it was exactly. I only had time for a short walk about this morning before getting a lift to the University campus, which is a bit out of town. I gave my talk as planned, had a nice lunch, and was personally driven back to the railway station, and am now on my way back to Barcelona.
I’ll probably doze off on the way, so I’ll just take this opportunity to thank Vicent Martínez for inviting me (including last night’s dinner) and everyone for their hospitality and nice questions after my talk!
Update: I got back to Barcelona about 15 minutes late, which wasn’t a big deal, although it’s a notably slower route than the Madrid-Barcelona line I travelled on a couple of months ago.
