I’ve just got time between meetings to mention that a clutch of brand new papers has emerged from the DESI (Dark Energy Spectroscopic Instrument) Collaboration. There is a press release discussing the results from the Lawrence Berkeley Laboratory here and one from the ICCUB in Barcelona here; several members of the group I visited there during sabbatical are working on DESI. Congratulations to them.

I haven’t had time to read them yet, but a quick skim suggests that the results are consistent with the standard cosmological model.

The latest batch contains three Key Publications:

together with the companion supporting papers:

The links lead to the arXiv version of these papers. These articles can also be found, along with previously released publications by the DESI Collaboration, here.

Anyone who has read the latest papers is welcome to comment through the box below!

In Praise of the Public Thesis Defence

Posted in Barcelona, Education, The Universe and Stuff with tags , , , , , on April 12, 2024 by telescoper

The ICCUB is quite large, which means that there are quite a few talks to go to, including seminars and colloquia but also thesis defences, such as one I attended this morning. The format for these events is a talk by the candidate in the presence of a panel of experts, who ask questions at the end, but the whole thing is open to the general public. After the panel questions there is an opportunity for questions from the audience, but only from those who have a doctorate. I was tempted, but didn’t put my hand up.

Anyway, this morning’s talk was well attended and of very high quality and, as usual, the whole event lasted getting on for two hours. It’s a very different experience from the form of viva voce examinations used for PhDs in the UK and Ireland.

I like to attend these public thesis defences because they’re a very good way of finding out about the research going on in areas away from my own specialism. In physics the people who are really working at the coal face are the PhD students so one often learns more about the details from such talks than from colloquia from senior folk, which are usually cover a wider area but at a more superficial level.

Another nice thing is that there is a little gathering afterwards (on the right) with a selection of food and drink available to celebrate the candidate’s success. In fact it was a double celebration as the candidate was offered a postdoctoral research position just two days ago. I abstained from the champagne as alcohol at lunchtime usually sends me to sleep in the afternoon, and I have a lot to do in the rest of today.

Physical Differences

Posted in Barcelona, Biographical, Education with tags , , on September 26, 2023 by telescoper

Today was my first day in the ICCUB…

I spent quite a lot of this morning trying to get my internet connections to work and trying to sort out an office key, not with 100% success. I am currently in the office of a member of staff who happens to be away today instead of the office I was allocated, and my email address here is not yet activated – probably because I did something wrong in the registration process. I’m hopeful that these minor issues will be resolved tomorrow. Even Eduroam acted up for a while before finally letting me connect. Such is life.

Anyway, my first impression on arriving in the building was of a huge difference in scale in Physics activity here at the University of Barcelona (UB) as compared to Maynooth (and indeed the UK Physics departments I have worked in). That’s not just the size of the building, which the Faculty of Physics shares with the Faculty of Chemistry. Physics and Chemistry also share a building in Maynooth, in fact, so the sharing was not in itself a surprise. The Science Building in Maynooth is very small, however, and it was a bit of a shock seeing how much space there is here compared with Maynooth, and also finding out how easy it is to get lost among the 7 floors. The sense of space is very refreshing, actually, as cramped accommodation is a constant reminder of financial and other constraints.

That’s not the only difference, though. There is enough activity in Physics in the University of Barcelona for it to be an entire Faculty. The UB Faculty of Physics contains Departments, covering the following areas: Electronic & Biomedical Engineering; Quantum Physics & Astrophysics; Condensed Matter Physics, and Applied Physics. It is also home to ICCUB, an interdisciplinary research institute that sits outside the Department structure and some of whose staff are paid from external agencies rather than the University itself.

In Maynooth there is a Faculty of Science and Engineering that covers all disciplines represented in the list above, and more besides. It would amuse my colleagues back in Ireland to see that Electronic Engineering is considered a small subset of Physics in Barcelona, whereas in Maynooth it is a free-standing department which is larger than Physics.

P.S. I just thought I’d mention another difference: that it is very warm here (26° C) so I may need to stop for a beer on the way home…
