That was the Science Week that was..

So, as advertised, this morning I gave a talk mainly to school students as part of Science Week Ireland on the subject of the cosmic web. This was a similar talk to the one I gave at DIAS a couple of weeks ago.


There was a slight confusion about rooms but we did eventually get everyone into the right lecture theatre and weren’t too late getting started. The audience was about 140, so the room was very full and most of them didn’t fall asleep. I had a nice chat afterwards with a group of them and they seemed to have enjoyed it. Anyway, in case anyone is interested here are my slides. Most of them are recycled from previous versions of this talk.

Following this morning’s exertions we had lovely seminar after lunch by Wyn Evans of Cambridge about the stellar dynamics of the Milky Way and the wonders of Gaia and soon will be going to dinner.

The Cosmic Web in Maynooth

Next week (10th to 17th November) in Ireland is Science Week and this will be celebrated by a number of events here in Maynooth, among which is a talk by yours truly on 15th November:

Here is a short description:

How can we map the distribution of galaxies over thousands of millions of light years? What does the Universe look like on these scales? How did get to look like that? And how do we know?This talk will explain how astronomers and cosmologists have come together over the past couple of decades to make huge surveys of the Universe, revealing the existence of a complex but beautiful `Cosmic Web’ with vast chains of galaxies strung out around immense dark voids. These observational breakthroughs have been mirrored by advances in theory and computer simulation that allow us to understand how this amazing structure was born 14 billion years ago in the Big Bang and has been growing and evolving ever since. Free and open to TY, 5th and 6th year students, this talk will be of particular interest in those interested astronomy, space, physics and the Universe itself!

It is on in the morning to make it possible for school students to attend and the talk is adapted to this audience, so it won’t be the same as the one I gave in Dublin last week. The timing seems to have worked because the lecture theatre has over 200 seats in it but is already almost full. There are still a few places available so if you’re in the area you can book here.



The Cosmic Web at DIAS

Yesterday evening found me at the Dublin Institute for Advanced Studies, complete with scary Hallowe’en beard, to give a talk.

It was a nice friendly audience and we had a lot of interesting discussions afterwards. As usual on such occasions I’ve put up the slides in case anyone wants to see them:

After the talk I headed back to Maynooth. It was a very rainy night, but at least some of the fireworks were going off despite the potential for damp squibs.
