A Trip on the Thames

Posted in Uncategorized with tags , on March 22, 2019 by telescoper

Last night as part of the social programme of this conference the participants went on a boat trip along the Thames from Westminster Pier to Canary Wharf and back. It was a very enjoyable trip during which I got to talk to a lot of old friends as well as mingling with the many early career researchers at this meeting. I can’t help thinking, though, that graduate students seem to be getting younger..

Meanwhile, back in Burlington House, astronomers have found observational evidence of modifications to Newton’s gravity..

The Most Ancient Heavens

Posted in Art, Biographical, Poetry, The Universe and Stuff with tags , , , , , , , , on March 21, 2019 by telescoper

So here I am, in that London, getting ready for the start of a two-day conference at the Royal Astronomical Society on cosmology, large-scale structure, and weak gravitational lensing, to celebrate the work of Professor Alan Heavens, on (or near) the occasion of his 60th birthday. Yes, it is a great name for an astronomer.

I was honoured to be invited to give a talk at this meeting, though my immediate reaction when I was told about was `But he can’t be sixty! He’s only a few years older than me…oh.’ I gather I’m supposed to say something funny after the conference dinner tomorrow night too.

Courtesy of alphabetical order it looks like I’m top of the bill!

Anyway, I’ve known Alan since I was a research student, i.e. over thirty years, and we’re co-authors on 13 papers (all of them since 2011). I’m looking forward to the HeavensFest not only for the scientific programme (which looks excellent) but also for the purpose of celebrating an old friend and colleague.

Just to clear up a couple of artistic points.

First, the title of the meeting, The Most Ancient Heavens, is taken from Ode to Duty by William Wordsworth.

Second, the image on the conference programme shown above is a pastiche of The Creation of Alan Adam which is part of the ceiling of the Sistine Chapel painted by Michelangelo di Lodovico Buonarroti Simoni, known to his friends as Michelangelo. Apparently he worked flat out painting this enormous fresco. It was agony but the ecstasy kept him going. I’ve often wondered (a) who did the floor of the Sistine Chapel and (b) how could Michelangelo create such great art when it was so clearly extremely cold? Anyway, I think that is a picture of Alan at high redshift on the far right, next to the man with beard who at least had the good sense to wear a nightie to spare his embarrassment.

Anyway, that’s all for now. I must be going. Time for a stroll down to Piccadilly.

Update: you can find a bunch of pictures of this conference here.

New Publication at the Open Journal of Astrophysics!

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , on March 20, 2019 by telescoper

It’s nice to be able to announce that the Open Journal of Astrophysics has just published another paper. Here it is!

It’s by Darsh Kodwani, David Alonso and Pedro Ferreira from a combination of Oxford University and Cardiff University.

You can find the accepted version on the arXiv here. This version was accepted after modifications requested by the referee and editor.

This is another one for the `Cosmology and Nongalactic Astrophysics’ folder. We would be happy to get more submissions from other areas of astrophysics. Hint! Hint!

P.S. A few people have asked why the Open Journal of Astrophysics is not listed in the Directory of Open Access Journals. The answer to that is simple: to qualify for listing a journal must publish a minimum of five papers in a year. Since OJA underwent a failure long hiatus after publishing its first batch of papers we don’t yet qualify. However, so far in 2019 we have published four papers and have several others in the pipeline. We will reach the qualifying level soon and when we do I will put in the application!

A Grand Slam Weekend

Posted in Biographical, Cardiff, Rugby with tags , , , on March 19, 2019 by telescoper

Well, here I am sitting in Cardiff Airport yet again waiting for a flight back to Dublin so I reckon it’s time to break my self-imposed blogging silence.

I had an enjoyable little break, the highlight of which was the rugby on Saturday between Wales and Ireland. I actually managed to get a ticket for the game, though I am not at liberty to divulge how I got it. I was a long way back from the pitch, practically in the rafters of the Principality Stadium, but the view wasn’t bad. Sadly, I forgot to charge my phone up overnight before the match and by the time I made it to my seat the battery had died, so I have no pictures of the event to share.

I had expected Wales to win, but hadn’t expected such a one-side match. After scoring after just over a minute, Wales controlled the game. Instead of the intense atmosphere I’d been anticipating, the mood in the crowd was more like that you might find at a cricket match while the home side is steadily accumulating runs against ineffective bowling. When the Ireland fightback hadn’t materialized by the fourth quarter of the game, the celebrations started and the singing grew louder in the steadily falling rain. At least Ireland got a consolation try at the end, but if truth be told they didn’t really turn up for the match.

I got absolutely drenched walking back to the Cardiff residence, but it was worth it for the privilege of seeing a Grand Slam unfold live. I only caught the second half of the final match of this year’s Six Nations, the Calcutta Cup match between Scotland and England, on the radio. This seems to have been the most exciting of the tournament, ending in a 38-38 draw after England had been 31-0 up! Greatest comeback since Lazarus!

But all credit again to Wales for their Grand Slam, a great achievement by any standards. It’s revenge what happened ten years ago, when I was in Cardiff (though not in the ground) for a Grand Slam decider between Wales and Ireland, a frantic and exciting match which Ireland won. Not so much excitement this time, but a far happier crowd of Welsh supporters!

So that’s the St Patrick’s Bank Holiday Weekend over with and I’m now heading back to Ireland. This week, or what’s left of it, is `Study Week’ which means there are no lectures. We have finished six weeks of teaching this term at Maynooth, and there are six more after Study Week but there is another week off looming for Easter. As it happens, I’m attending a small conference in London on Thursday and Friday (of which more soon) so I’m just back in the office tomorrow before flying off again for two days in the capital of Poundland.

Interlude

Well, it’s St Patrick’s Day on Sunday (17th March), the day before which is a certain rugby match between Wales and Ireland in Cardiff, and the day after which is a Bank Holiday in Ireland. I’m therefore taking a short break to enjoy the long weekend. Normal service will be resumed as soon as possible, but in the meantime there will be a short intermission.

Semper Cavete Quod Idibus Martiis

Today is the Ides of March so I thought I’d keep up the little tradition I’ve established of posting this  priceless bit of British cultural history relevant to such a fateful day.

This is from the First Folio Edition of Carry On Cleo, and stars the sublime Kenneth Williams as Julius Caesar delivering one of the funniest lines in the whole Carry On series. The joke may be nearly as old as me, but it’s still a cracker…

They – by R.S. Thomas

Posted in Poetry with tags , , on March 14, 2019 by telescoper

The new explorers don’t go
anywhere and what they discover
we can’t see. But they change our lives.

They interpret absence
as presence, measuring it by the movement
of its neighbours. Their world is

an immense place: deep down is as distant
as far out, but is arrived at
in no time. These are the new

linguists, exchanging acrosss closed
borders the currency of their symbols.
Have I been too long on my knees

worrying over the obscurity
of a message? These have their way, too,
other than a prayer of breaking that abstruse code.

by R.S. Thomas (1913-2000)

It’s nice to be able to announce that the Open Journal of Astrophysics has just published another paper. Here it is!

It’s by Pauline Barmby of the University of Western Ontario. You can find the accepted version on the arXiv here.

I think this paper is a good demonstration of the broad remit of the Open Journal of Astrophysics: our only rule is that if it’s suitable for the astro-ph section of the arXiv then we will consider if for publication. Rather than being a hardcore research paper, this is comprehensive and pedagogical review of observational techniques, instrumentation and data analysis in astronomy for use by researchers and educators in other disciplines, which we feel is a very useful addition to the literature

My thanks to the Editor and referees for dealing with this one so efficiently! We even have a Twitter testimonial from the author:

We have more publications in the pipeline but would be more than happy to receive more…!
I hope soon to get to the point where we have so many papers I can’t write a blog post about every one!

Theresa May: Friend of Hedge Funds

Posted in Uncategorized on March 12, 2019 by telescoper

Compare and contrast the following behaviour of the Pound Sterling versus the Euro last night

And this morning

Of course the Pound’s rise yesterday was based on speculation that the Prime Minister Theresa May’s trip to Strasbourg would lead to changes to the Withdrawal Agreement between the UK and EU that would make it acceptable to the House of Commons (by which I mean to the pro-Brexit faction of the Conservative Party). The subsequent fall this morning is explained by the fact that she achieved nothing of substance and the Withdrawal Agreement is unchanged.

It seems to me that there are two possible explanations for yesterday’s elaborately choreographed charade. Only a fool would think that Mrs May succeeded in negotiating a concession from the EU, but one thing she can be sure of is that the House of Commons (and particularly the Conservative Party) has plenty of fools in it. The PM might have thought this absurd piece of flummery was worth a shot and convincing Tory buffoons who haven’t read the Withdrawal Agreement anyway. It might even* work!

On the other hand, regardless of what happens in this evening’s `Meaningful Vote’, one thing is clear. Some currency traders will have made an awful lot of money by short-selling the pound. Theresa May’s Strasbourg pantomime will undoubtedly have made her very popular among the Hedge Fund Managers who in any case are the main financial beneficiaries of Brexit…

*It worked with some, but not enough to stop the deal being lost by 149 votes.
