Back from the Dead!

Posted in Barcelona, Biographical with tags , , on June 21, 2024 by telescoper

As I reported a couple of days ago, my laptop (which is about 6 years old) failed to restart when I got back to Barcelona from Rome.

I couldn’t attempt a reply until I got a key from IT Services in Maynooth. The 48 digits duly arrived yesterday.  I tried a number of times to repair the disk but it kept failing. Last night I left a disk scan running when I went to bed, as it advised that several hours would be needed. When I got up this morning I found it had failed again.

I decided to try one more time, started the recovery process again and went out shopping. It was still running when I got back. I had all but given up at this point and had stopped paying attention to the screen. When I finally went to check again I saw to my amazement that it had restarted as far as the Windows login.

I logged in with fingers crossed. It took an eternity to start up and is still running very slowly. It’s probably quite ill, perhaps more undead than alive, but at least I could retrieve my files onto the hard disk I brought with me.

I have to travel to Valencia next week to give a talk and was wondering how I would manage without having access to my slides let alone a laptop to present them from…

Anyway, I’m nervous about what might happen if I have to restart again, so I’ll leave it on while I celebrate with a glass or several of wine. The Resurrection of the Laptop may well prove to be temporary but I’ll make the most of it while it lasts…

The Summer Solstice 2024

Posted in Barcelona with tags , , on June 20, 2024 by telescoper

With all the excitement I almost forgot that Summer Solstice in the Northern hemisphere takes place later today, Thursday 20th June 2024, at 21.51 Irish Time (20.51 UTC) or 22.51 local time here in Barcelona.

Among other things, this means that today is the longest day of the year around these parts. Sunrise in Barcelona this morning was 06:17 and sunset at 21:28.  The length of the day – the interval between sunrise and sunset – today is 15:10:13. Compare this with Dublin (sunrise 04:56, sunset 21:56, and day length 17:00:12).

This Sunday (23rd June)  sees the Feast Day of St John (Sant Joan),  which is celebrated in Barcelona with fireworks and bonfires, and people partying all night long on the beach. Monday is a holiday, presumably to allow people to recover. I am, of course, far too old, for that sort of thing.

Chaos in Rome and Barcelona

Posted in Barcelona, Euclid, Mental Health with tags , , , , , , on June 19, 2024 by telescoper

What I thought would be a straightforward trip back from Rome to Barcelona turned into nothing of the sort.

I arrived at Roma Termini station and got on a train for Fiumicino Airport. The train didn’t move, however, and eventually we passengers were told that we should get off and take a bus or a taxi because of “a problem on the line” which would take an indefinite time to fix.

I went to see if I could get a bus, but the queue was predictably enormous. Same story for taxis. After waiting over an hour I had all but given up hope of catching my flight when suddenly it was announced that the track problem was fixed and I got back on the train. It reached the airport in good time and I passed a very long queue of people waiting to travel in the opposite direction; trains into Roma Termini from Fiumicino had also been cancelled:

I still thought I would miss the flight, but I thought that once in the airport I could perhaps book another. Helped by the fact that I had already checked in online and only had hand luggage, however, I made it through security and to the gate just  in time to board.

So, all seemed well. I’ve travelled enough in Italy to have learnt how to cope with a fair amount of chaos.

I got back to Barcelona – which is somewhat cooler than Rome – just about on time and took the Aerobus as usual. Unfortunately, I had forgotten that today was the day that roads in the area around my flat were closed for a Formula 1 “Road Show”. The bus stopped at the edge of the sealed off area and passengers – many heavily laden with luggage – were left to make their way through the dense crowds. Whoever decided it was a good idea to block some of the busiest roads in Barcelona during the evening rush hour has a lot of questions to answer. The crush around Plaza de Catalunya was absurd and potentially dangerous, and not only for people like me who find such situations very difficult.

When I eventually got to my flat, I saw a protest against this stupid event had let to standoff in the street with some sinister-looking cops.

At home, and after a relaxing shower, I thought the day’s tribulations were over until I switched on my laptop and found it wouldn’t start:

Automatic Repair didn’t work so I logged a ticket with Maynooth IT Services. If they can’t fix it, it looks like I’ll be unable to work until I get a new machine…

…and blogging using my phone like this!

The Mystery Object

Posted in Euclid with tags , , , , on June 18, 2024 by telescoper

Among the various items of Euclid Merch in the goody bag given to attendees at the annual Euclid Consortium Meeting in Rome are a nice bag, a cap, a notebook, and a mystery object:

Can anyone suggest what this item does?

(Wrong answers preferred.)

Sono arrivato a Roma

Crossing the Italian Coast

This morning, I took a short (~ 90 minute) flight from the pleasantly warm (23°C) Barcelona to the swelteringly hot (31°C) city of Rome. It’s actually forecast to be 39°C on Thursday and 40°C on Friday. Fortunately, I’m not staying that long!

The occasion for this trip is the annual Euclid Consortium Meeting, which is being held at the Università degli Studi di Roma “La Sapienza“. The main sessions are in the splendid Aula Maxima thereof, with its imposing mural:

I’m giving a talk there in the first plenary session  tomorrow…

Update: here’s me giving my plenary talk:

Bogus Scopus

Posted in Open Access with tags , , , , on June 17, 2024 by telescoper

Just to show that I’m not alone in having severe doubts about the reliability and integrity of Scopus here is an article from Retraction Watch that points out that three of the top ten philosophy journals (according to that database) are fake. Among the facts that could easily have been checked by a competent agency is this:

The same editorial board serves for three journals, with 10 members who are dead. 

The article concludes:

Rankings based on Scopus frequently serve universities and funding bodies as indicators of the quality of research, including in philosophy. They play a crucial role in decisions regarding academic awards, hiring, and promotion, and thus may influence the publication strategies of researchers… Our findings show that research institutions should refrain from the automatic use of such rankings. 

Quite. Any institute that has signed up to the San Francisco Declaration on Research Assessment should not be basing any decisions on Scopus anyway, but I don’t think that goes far enough. Scopus is a corrupting influence. It is high time for universities and other agencies to stop paying their subscriptions and ditch it entirely.

Bloomsday Barcelona

Posted in Barcelona, LGBTQ+, Literature with tags , , , , , , on June 16, 2024 by telescoper

So it’s June 16th which means it is Bloomsday. I looked around for ways to celebrate this day in Barcelona and found that there is a Irish bar on La Rambla called Bloomsday. When I went there, though, I was disappointed to find it not only closed, but apparently abandoned:

Barcelona gets a mention – just one – in James Joyce’s Ulysses:

Noon slumbers. Kevin Egan rolls gunpowder cigarettes through fingers smeared with printer’s ink, sipping his green fairy as Patrice his white. About us gobblers fork spiced beans down their gullets. Un demi sétier! A jet of coffee steam from the burnished caldron. She serves me at his beck. Il est irlandais. Hollandais? Non fromage. Deux irlandais, nous, Irlande, vous savez ah, oui! She thought you wanted a cheese hollandais. Your postprandial, do you know that word? Postprandial. There was a fellow I knew once in Barcelona, queer fellow, used to call it his postprandial. Well: slainte! 

I can confirm that there is no shortage of queer fellows here, but I’ll have to have my lunch before I can have a postprandial but slainte! to you too.

The Mooche – Steve Lacy

Posted in Jazz with tags , , , , , on June 15, 2024 by telescoper

Duke Ellington’s tune The Mooche, composed in 1928, belongs to an era that spawned many other atmospheric classics such as Luis Russell’s Call of the Freaks and Don Redman’s Chant of the Weed. Fifty years later the menacing undertone of The Mooche was seized upon by saxophonist Steve Lacy and turned into an unforgettably raw version on his 1978 album Points (which I bought on vinyl when it first came out) in which he duets on soprano with Steve Potts, delivering the haunting minor-key theme with a sound like knives being sharpened.

Two New Publications at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , , , , , on June 15, 2024 by telescoper

It’s Saturday morning in Barcelona, and time to post another update relating to the  Open Journal of Astrophysics.  Since the last update we have published two more papers, taking  the count in Volume 7 (2024) up to 47 and the total published by OJAp up to 162. We actually accepted four papers last week, but so far only two final versions have appeared on the arXiv.

The first paper of the most recent pair – published on  Friday 14th June – is “Spectroscopic Confirmation of an Ultra-Massive Galaxy in a Protocluster at z 4.9″ . The author list has a strong University of California flavour: Stephanie M. Urbano Stawinski (UC Irvine), M. C. Cooper (UC Irvine), Ben Forrest (UC Davis) , Adam Muzzin (York University, Canada), Danilo Marchesini (Tufts University), Gillian Wilson (UC Merced), Percy Gomez (Keck Observatories, USA), Ian McConachie (UC Riverside), Z. Cemile Marsan (York University, Canada), Marianna Annuziatella (Centro de Astrobiología CSIC-INTA, Spain) and Wenjun Chang (UC Riverside).

This paper presents an investigation of a cluster system involving a massive galaxy using Keck spectroscopy with determination of its redshift and star formation properties. The results pose a challenge for theorists. The paper is in the folder marked Astrophysics of Galaxies.

Here is a screen grab of the overlay which includes the abstract:

The second paper, also published on Friday 14th June and has the title “Boil-off of red supergiants: mass loss and type II-P supernovae” by Jim Fuller (Caltech) and  Daichi Tsuna (Caltech, USA and University of Tokyo, Japan). This one, which is in the folder marked Solar and Stellar Astrophysics, discusses A new model for stellar mass loss which predicts that low-mass red supergiants lose less mass than commonly assumed, while high-mass red supergiants lose more.

Here is a screen grab of the overlay which includes the abstract:

That concludes this week’s update. Will we reach 50 for 20204 next week? Tune in next Saturday to find out!

The Scream with Paper Clips

Posted in Art with tags , , on June 14, 2024 by telescoper

I was not inconsiderably amused by the above homage to The Scream by Edvard Munch which I see as a powerful artistic response to pointless corporate bureaucracy. It was created by Adam Hillman, an artist who specializes in making interesting designs and collages from everyday objects. You can read more about, and see more examples of, his work here.
