Me and my work

I am searching for groups of really distant galaxies.

The galaxies (collections of stars) I am looking for are over 10^22 m away, that’s a 1 with 22 zeroes after it or 15 million times the size of our galaxy and our galaxy is 150 million million times the size of a football pitch! So finding these galaxies is no easy task, but the advantage to looking this far away is that we are also looking back in time – in fact 12 billion years back. As the speed of light is fixed, it takes time for the light from these galaxies to travel to us and so when we finally see the light it’s the light from billions of years ago. Confused? Think about a man running with a message from London to Bristol. When he gets to Bristol the message will be old, it’ll tell us about what happened when he left London a day ago. It’s the same idea, the light is ‘old’ when it gets to us and carries important information about what happened all that time ago.

So to summarise, my work is searching for clusters (or groups) of these very distant galaxies to try and work out how galaxies formed in the first place.

My Typical Day

Come about 8.30am, faff on the internet for 5-10mins, write some code for a few hours, coffee, more work, lunch, more work including reading some papers and perhaps a chance to quiz my supervisor. Leave about 5pm.

Coffee time is an important time, not only do the group get together for some caffeine  and a chat (and cake on Fridays) but you can ask everyone about the problems your having and see if anyone can help. I have a weekly meeting with my supervisor (basically my boss) on Mondays. We also have a weekly seminar where an external speaker will come and talk and his/her work for an hour.

What I'd do with the money

I would donate the money to HiSPARC – a project I am involved with to install cosmic ray detectors on the roofs of schools for use by students like you.

Cosmic rays are energetic particles (mainly protons and electrons) from space which bombard our atmosphere all the time. When they hit molecules in our atmosphere they create secondary showers of particles that rain down on us. They most likely come from far outside our solar system but even today their origin is not 100% certain.

HiSPARC was originally started in the Netherlands but has recently been introduced in the UK by one of the lecturers here in Bristol. It allows students to build cosmic ray detectors themselves and then look at the data, from their detector and the whole network of detectors, to try and find out about these mysterious cosmic rays. You can see some of the data being taken here: http://data.hisparc.nl/show/stations_by_country/

If you’d like to be involved get your teacher to email Jaap Velthuis at Bristol University, but you might need to vote for me too – the materials for the detectors don’t come cheap!

 

My Interview

How would you describe yourself in 3 words?

Curious about everything

Who is your favourite singer or band?

Muse,

What's your favourite food?

Pizza

What is the most fun thing you've done?

The Sodbury Slog – a very muddy 10mile running race in November. Google it.

What did you want to be after you left school?

Scientist or plumber

Were you ever in trouble in at school?

Not much.

What was your favourite subject at school?

Maths and Science. I had the two best teachers in the school teach me Maths and Physics, and I’m not just saying that because I like Maths and Physics.

What's the best thing you've done as a scientist?

Gone to use telescopes in Chile and Hawaii (see pictures below).

What or who inspired you to become a scientist?

Teachers a little but mainly I do science because I enjoy it and always have.

If you weren't a scientist, what would you be?

Bored

If you had 3 wishes for yourself what would they be? - be honest!

Tell us a joke.

Other stuff

myimage1 Some of the 13 telescopes on the top of Mauni Kea in Hawaii. The telescope I was using this Easter (the JCMT) is just to the left of this image and the two round domes are the Keck telescopes. You can just see the island of Maui in the background.

myimage2 The VLT (or Very Large Telescopes – us scientists are imaginative!) in Chile, which I used 18 months ago. In each of the 4 big huts is a telescope with a mirror 8m in diameter.
