Sydney looking back

Posted in Biographical with tags , , , , on March 5, 2024 by telescoper

I am a bit jet-lagged, and don’t have the energy for anything too strenuous, so I thought I’d post a couple of reflections of my time in Sydney. Actually I wrote this piece yesterday but was so tired I forgot to post it!

The first thing I should say is that Sydney is a very fine city. I really enjoyed my time there. Although I had four weeks there are still many things I didn’t get to do. Had I been on holiday for a month I might have seen more, but I was actually working a lot of the time. Perhaps I’ll go back when I’ve retired! It was a last-minute decision to go, actually. I only decided in January to make the trip. Had I had more time to plan things I would have been more organized.

One issue with Sydney is that it is very expensive. That goes for food and drink as well as accommodation. I might have found a cheaper place to stay had I looked earlier, of course, but everyone there told me it was always difficult to find rental properties. A while ago I read a story about how and why many young Irish people are moving to Australia. Sydney is even more expensive than Dublin to live in, and there’s just as much difficulty in finding somewhere to rent. On the other hand, in Australia there is a lot more sunshine than in Ireland!

Sydney is also very cosmopolitan and culturally diverse. The most obvious sign of this is the huge range of different cuisines. I rented an apartment with a kitchen rather than a hotel room because I was there for so long that I thought I would do a significant amount of cooking. As it turned out, though, there were many relatively inexpensive eateries nearby, some of them very good indeed, so I didn’t cook all that much.

A Cockatoo or Three

Another thing that struck me at first was the huge difference in flora and fauna, especially the birds. I’ve mentioned some of them before but I should say something about the cockatoos. These are far more numerous than I’d imagined and are rather gregarious, often swooping around in large flocks. They are cute but somewhat deranged creatures, often very noisy and sometimes downright destructive. You don’t want to let one into your house. They are naturally inquisitive and use their strong beaks and dextrous claws to dismantle things. Like all indigenous birds, cockatoos are protected by law. I rather think they are aware of this immunity as they are very cheeky. Strange as they are, I got used to their squawking and screeching. I miss them a bit already.

Anyway, I’m now pretty much recovered from the jet lag – just in time for another flight. It’s going to be a busy ten days or so before I return to Barcelona. A student of mine has their viva examination next week. Although at Maynooth University the supervisor doesn’t attend these examinations, I feel I should be on hand to buy champagne and offer congratulations. And talking of congratulations, I just found out this morning that, after a number of postdoctoral positions, a former PhD student of mine has joined the staff at a UK university. I’m very happy about that – what special delight you feel when you hear one of your former PhD students has got a permanent job!

Homeward Bound

The Blue Mountains

Here I am in Abu Dhabi airport, about 2/3 of the way home from Sydney, with just enough time for a quick post. We took off about 4pm Sydney time and I had a window seat with a good view of take-off and parts of Australia, including the famous Blue Mountains just to the West of Sydney, but it soon got dark. My flight leaves Abu Dhabi at 2.20am local time and arrives in Dublin at 6.30am local time, so most of this will be in darkness too!

Anyway, farewell Sydney! I’ve enjoyed being in you!

Update: After some minor excitement caused by my having a nosebleed on the plane, I made it back to Dublin in one piece and on time, though there was a long delay on the bus from the Airport owing to an ‘incident’ on the M1 near the airport, so I was about an hour later than expected getting home. I won’t be here for long before I jet off again, but I do need a little time to rest.

Weather Conditions

This is my last full day in Sydney and – by sheer coincidence – it happens to be Sydney Gay & Lesbian Mardi Gras! I will probably go out later to watch some of the fun, although it seems it’s very likely to rain on the Parade; it’s very overcast this morning, although the temperature is still 24°C.

Talking of the weather, I noticed on social media that yesterday it snowed in Maynooth (and elsewhere in Ireland). The contrast with what I’ve been experiencing in Sydney will be rather extreme:

I was a bit concerned that the snow might cause problems with my return flight and/or onward transport, but I’m told that it was soon washed away by rain.

I’ll only be making a brief stop in Maynooth before travelling to (different) warmer climes, of which more in due course.

Western Sydney

Posted in Biographical, Open Access with tags , , , , , , on February 26, 2024 by telescoper

Today I made a journey by train to Kingswood, a suburb of Sydney which is the location of one of the campuses of Western Sydney University (WSU). The journey of about 50 km takes about an hour on the stopping train (T1) from Sydney Central Station. I was intrigued that the final destination for the train I got was Emu Plains; I had visions of vast herds of Emus gathered there, but I had to get off the stop before the terminus so never saw them. There’s about a 20-minute walk to the campus from Kingswood Station. It was quite warm so I was grateful when one of my hosts offered me a lift back to Kingswood Station at the end of my visit.

The reason for my visit was set another seminar about Open Access Publishing in Astrophysics. Here are the slides:

Although I’ve given a talk based on more-or-less the same slides recently, it always comes out slightly different. There was a bigger audience than I expected in the room, supplemented by even more on Zoom. The topic of Open Access Publishing does seem to be pretty hot these days in Australia and there was quite a lively discussion. I have a feeling we might have a manuscript or two submitted from WSU before too long.

Kingswood is a far less affluent area than where I am staying in Ultimo, and WSU is an institution that’s very different from the University of Sydney itself, but it was good to see another side of the city, geographically as well as socially. Thank you to everyone who attended and, especially, to Luke Barnes for inviting me and for lunch and coffee!

On the train back into Sydney I noticed that trains going in the opposite direction where crammed full, with (mostly) teenage girls heading to Olympic Park for a Taylor Swift concert. My train, heading into Sydney was fairly empty by contrast and the journey back pleasant enough.

A Manly Excursion

Posted in Architecture, Biographical with tags , , , , , on February 25, 2024 by telescoper

I realized this morning, with a shock, that I only have one more week in Sydney so I decided to cross off another of my things to do by taking the ferry (F1) from Circular Quay to Manly, so I could have a view of the Pacific Ocean. The most fun was on the way back, when a yacht race was under way in Sydney Harbour. Lots of small boats had come out to get a good view, many of them right in the ferry path. An officer of the Harbour Police on a jet ski was buzzing around politely inviting the offenders to get out of the way. At one point a quite large boat came right across our bow and the captain of the ferry had to sound the alarm. No harm was done, but that clown could have caused a serious accident.

Anyway, there are lots of Manly things in Manly: a Manly Wharf, Manly Beach, a Manly Bank, Manly Pharmacy and, as you can see in one picture, Manly Paradise; there’s even, as pointed out to me by Richard Easther, Manly Astrophysics. I only stayed long enough to have a Manly beer and some Manly Fish & Chips before heading back to Circular Quay.

Here are some snaps.

Anyway, here are a few little videos from my instagram page:

The Hottest Day

Posted in Biographical with tags , , , on February 23, 2024 by telescoper

Today has been the hottest day of my visit to Sydney (so far). It was already 30°C by 11am, and got warmer as the day went on, reaching 35°C by 3pm, reaching a peak of almost 37°C by 4 o’clock. I was struggling a bit by then, and decided to go back to my air-conditioned apartment for a rest. I got there just before the lovely rain came; no thunder or lightning today though.

I was prepared for the high temperatures here, but at this time of year it is very humid which I find much more difficult to deal with. The hottest place I have ever been in was Aswan in Egypt, where it was 48°C in the shade, but it was very dry and I didn’t find it all that troublesome. I was careful to drink plenty of water, as I could feel myself evaporating, but other than that it wasn’t all that bad. Years ago I went to New Orleans where the temperature was barely 30°C but the humidity so oppressive I could barely function at all, even at night.

Anyway, out of curiosity, I googled the highest temperature ever recorded in Sydney, which turns out to have been recorded at Penrith with a high of 48.9 °C (120 °F) on 4 January 2020. Yikes! Coincidentally, I am going to Penrith on Monday to give a talk at Western Sydney University. The forecast for there and then is a mere 28°C…

SN1987A, Past and Present

Posted in Biographical, The Universe and Stuff with tags , , , , , , on February 23, 2024 by telescoper

There’s a new paper in Science featuring observations using the MIRI and NIRSpec instruments on JWST of Supernova SN1987A in the Large Magellanic Cloud. I couldn’t resist doing a short post about this result, partly because the paper features Maynooth colleague Paddy Kavanagh, and partly because I’m old enough to remember when this supernova was detected, in 1987. In fact I was doing my PhD at the time. When I started lecturing a few years later I used to use it as an example of a Type II (core-collapse) supernova. At first I would say “you will remember SN1987A” then, as the years passed, I realized that students would have been quite young in 1987 so I changed this to “some of you will remember SN1987A”. Still later, I realized that none of my students had even been born in 1987 so I forgot about the remembering bit and just talked about SN1987A. As of 2024, nobody under the age of 37 was born in 1987. Tempus has a distinct tendency to Fugit.

In 1987 I was in Sussex and I remember Roger Tayler getting very excited about the detection of anti-neutrinos from SN1987A at the Kamioka Observatory in Japan. There weren’t many – 12 altogether – but he wanted to do a statistical analysis of the arrival times to see if there was any evidence that might indicate the neutrinos had mass. Being rather “old-school”, he did a Monte Carlo experiment involving drawing numbers written on bits of paper out of a cardboard box. After a brief chat I suggested I could do a much better job using a random-number generator on a computer so I wrote a bit of code and did the computation. The results showed no evidence for neutrino mass.

Anyway, this type of supernova should produce a neutron star or black hole sitting inside a ring-shaped remnant. The ring has been well studied, but in 37 years of observation the central object has not been detected. The results in the latest paper (by Fransson et al.) involve a spectroscopic study of the emission lines of ionized argon from the SN1987a remnant at sufficiently high spectral resolution to map the velocity structure. The results suggest that ionizing radiation from a neutron star is illuminating gas from the inner parts of the remnant.

Open Access Talk at UNSW

Posted in Biographical, Open Access, The Universe and Stuff with tags , , , on February 21, 2024 by telescoper

After an exciting start to the day involving a fire alarm and consequent evacuation of my hotel, I today ventured into the suburbs of Sydney via the Light Rail system (i.e. the tram) to the University of New South Wales. The tram ride took about 20 minutes from Central and, incidentally, took me right past the Sydney Cricket Ground. Anyway, the UNSW campus at Kensington is very impressive:

After a few gremlins with the WIFI connection, the talk I gave was a longer version of the one I did at the University of Sydney on Monday. In discussions with the Astrophysics group at UNSW, I found they were particularly unhappy about the decision of Monthly Notices of the Royal Astronomical Society to charge a high level of APC (Article Processing Artificial Profit Charge) so is looking at alternative journals that aren’t so exploitative. A journal has no right to call itself “open access” if it excludes researchers on grounds of cost. The problem with the Open Journal of Astrophysics in this case is that they need their publications to be in “high impact journals” for research assessment purposes, and OJAp doesn’t have an “official” journal impact factor yet. The fascination of bureaucrats with the obviously flawed journal impact factor disturbs me greatly but I hope we will have one soon so we may be able to help them out before too long.

Anyway, here are the slides from today’s talk:

A Sunny Afternoon in the Botanic Gardens

Posted in Biographical with tags , , , on February 17, 2024 by telescoper

I took a stroll this afternoon in Sydney’s splendid Royal Botanic Garden. It was quite warm, so I soon had to retreat into a bar for some light refreshment, but not before I took a few snaps. The last one, incidentally, is of a wedding ceremony…

Two of the pictures show examples of Australian birds that are common in Sydney. The Australian White Ibis – called “Bin Chickens” because of their scavenging habits – look rather elegant from a distance but close up look rather manky. The smaller bird on the arm of the bench is a Noisy Miner. These are aggressively territorial, rather like the Eurasian Robin familiar to folk in the Northern hemisphere. They are also rather noisy. The other common native bird I see frequently is the Cockatoo. I’ll do a separate post about these very peculiar creatures when I get some decent pictures.

Asbestos in the Park

Posted in Biographical, LGBTQ+ with tags , , , on February 15, 2024 by telescoper

Time, I think, a bit of local news. There’s an ongoing asbestos crisis not only in Sydney but across all New South Wales. It seems that the mulch that has been used in many public parks, school grounds and even a hospital garden is contaminated with asbestos. One affected site is Victoria Park, which I walk through from my flat to the University. At least the park is still open, so you can walk on the paths and sit on the lawns, but all areas with mulch are fenced off:

As it happens, Victoria Park was to be used for one of the events planned for Sydney Mardi Gras, which starts today*, but that particular event has been cancelled though many others are unaffected.

The contaminated mulch at all the sites affected was supplied by the same company, Greenlife Resource Recovery. I hope they have to foot the bill for clearing it all up!

*It is, of course, a complete coincidence that this LGBT festival coincides with my stay in Sydney…
