A day in the life: Conference

In April 2011 the Jodcast team attended the National Astronomy Meeting in Llandudno. This video follows Jen as she shows you a day in the life of an astronomer at a conference. You can find the full interview with Dr Haley Gomez in the May 2011 Extra show and an interview with the plenary speaker, Professor Gianfranco Bertone, in the June 2011 show.

Transcript

Jen (): Hello I'm Jen and in this video I'm going to give you an insight into a day in the life of an astronomer at a conference.

Jen (): Today we're at the National Astronomy Meeting 2011 here in Llandudno in North Wales. The National Astronomy Meeting is the biggest meeting of astronomers in the UK. There will be about 500 people here, it's a 4 day conference with lots of sessions and we're going to go inside and check it out.

Jen (): Because there are so many astronomers here with different research interests, the majority of the National Astronomy Meeting is split into what are called parallel sessions, so they cover everything from solar physics to cosmology, future instruments and everything like that. Today, this morning, we're going into the explosive transients, AGN and black holes session which is the one that I'm going to be talking in later today.

Jen (): So it's the first coffee break of the conference but unfortunately instead of going downstairs and having a drink and socialising with people, I'm stuck up here in the room where I'm going to be giving a talk in the next session.

Jen (): So AGN, you've got a central black hole surrounded by an accretion disk, obscuring dust torus, clouds of gas create a broad line region and a narrow line region and you've got these two radio jets emitted from the poles. So blazars are the AGN where one of those radio jets is directed towards us at a very small angle to the line of sight...

Jen (): So I'm here today with Dr Haley Gomez from Cardiff University, welcome to the Jodcast. So you study dust in galaxies, can you tell us what's so special about dust in the universe?

Dr Haley Gomez (): Well if you take dust as the building blocks of life, we're basically talking about solid particles in space. It could be carbon, it could be diamonds, it could be glassy materials, it could be anything like that. And it comes from stars, stars slightly more massive than our Sun and it gets chucked out of these stars and it pollutes the stuff inbetween stars and galaxies and we want to know how that gets formed and how that goes into planets, how it goes into us, I mean we're basically a lump of dust, so where we come from...

Jen (): Now because there are so many different areas of astrophysics that are being discussed here at the National Astronomy Meeting and all these sessions are running in parallel so there are several sessions going on at one time discussing different physics, it can be quite hard to actually get an overview of what's being discussed. So the organisers put on what are called plenary lectures where they invite an expert in each field that has a session and everyone's invited to come along so there can be up to 500, 600 people in these lectures and you get an overview of the science that's being discussed. So let's go and listen to one of those now.

Professor Gianfranco Bertone (): ...the existence of a new scheme in physics and the existence of new particles, so a new level of physics with a new hierachy of particles. In the language of supersymmetry, for instance, for each particle in the standard model there will be a supersymmetric partner...

Jen (): So we've made it to afternoon coffee. Unfortunately I missed coffee this morning due to stressing over my talk, but coffee at conferences is a really great way to meet with people and network with other people who might be at different institutes so you don't normally get to see them. At the National Astronomy Meeting it's a bit different because some companies and telescopes also have stands here. So behind me you can probably see the ALMA stand. There's also LOFAR, eMerlin, Herschel and Planck and some of the publishers are here with astronomy textbooks for sale. At coffee as well in here we've got the poster boards, so quite a few people if they don't get a talk, especially students, will present a poster instead with their research and then over coffee will have the opportunity to tell people about what they're doing.

Jen (): So it's the end of a very long day here at the National Astronomy Meeting, there's been lots of good talks, lots of interesting science but now it's off to the pub for a well deserved drink. Hope you've enjoyed the video and we'll see you next time.

    It's taken us a while but we've finally put together a video following me while I was at the National Astronomy Meeting in April :-D

    Great Video even my 12yr old Daughter kept looking over to see what was going on :)

    Ha! Just noticed you can see my arm drinking conference coffee in one of the scenes! :D WIN

    Hello,

    ah, I miss going to conferences. Too bad my current job description does not include conferences. But next week I will attend a small two day conference ;).

    Regards

    nice little short, I could view it on my phone.
    more please :-)

    Great vid.

    Curiosity got the better of me and I had to look up what a Blazar is - "A type of Pulsar with no spectral lines" - not sure I'm any the wiser. I'm sure someone's probably joked that a Blazar is a Pulsar with a jacket on (sorry about that).

    Coincidentally, I was listening to another astronomy podcast who were interviewing - and here's a name that you might of heard of - Evan Keane of the Max Planck Institute. He was talking about how a paper by Martin Rees from 1979 describes the likely emission you'd see from a collapsing or colliding black hole(s) and how it is has similar characteristics to a Pulsar. You can start to see how Blazars, Pulsars, Black holes, AGNs etc are all linked together.

    The Jodcast has a great website. I was going through the archive to find the video of the eMerlin road trip but couldn't find it. Is it still in production or has it passed me by?

    @MarkC

    Blazars are a type of Active Galactic Nuclei, not a type of pulsar. There's some info on the Universe Today website http://www.universetoday.com/30594/blazars/ (I would write more but I'm about to get on a train!). I keep meaning to do a blog post about them so maybe I'll do that on the train :-D

    Not sure if you're joking about knowing Evan? He's part of the Jodcast! He's been on a few shows this year, starting with interviewing Dara O Briain in the January Extra.

    Finally, the eMerin video is still in post production, Tim is making some final minor edits and I really really really (!) hope it will be done soon :-D

  • Comment by Jodatheoak on Aug 15 2011:

    Did you know that Dara has magical powers and if you rub shoulders with him you start to form a celebrity aura... ;-)

    It's all in the stars.

  • Comment by MarkC on Aug 15 2011:

    Oops, sorry Jen, thanks for the link. I was getting my pulsars and quasars mixed up - I even looked it up!

    I was joking about Evan. It was when they introduced him as from the Max Planck Institute and he went on to say that he spends time looking through large datasets from Jodrell Bank searching for Pulsars (and this timne I do mean Pulsars) that I thought - 'oh how fickle alliances are'. Being serious for a minute though - it was good to hear him speak again.

    Good morning,

    # Finally, the eMerin video is still in post production, Tim is making some final minor edits and I really really really (!) hope it will be done soon :-D

    that's what we all hope ;). Thanks for your work.

    PS: I just looked up how I can go to Machester by train. It takes 10 hours. Hmmm ;).

  • Comment by MarkC on Aug 16 2011:

    I see where the word Blazar comes from: BL Lac + quasar = Blazar; then I had to go look up what a BL Lac was.

    If they don't have any spectral lines in their spectrum, can you still figure out their red-shift and work out their distance?

    Presumably if the relativistic jets (which I think is like a group movement of particles going faster than individually?) are pointing towards us then it gives a big radio signal and is easier to spot. If the jets are produced by a large magnetic field, which in turn is produced by a super-massive black hole, then it'll have an excretion disk and will capture lots of other objects. Does this mean you can see it in lots of wavelengths?
