We Discovered an FUor

December 20, 2018

We discovered a very rare kind of star – in fact there are only 25 stars of its type known to exist. The fact that we found it is amazing, but the way we found it was even more interesting. We caught it red handed during an FUor outburst – a period of intense flaring...

Beginning with BibTeX – Making Referencing in LaTex as Easy as Pi

August 14, 2016

[mathjax] It’s no secret that physicists love using LaTeX to write papers. This has many practical advantages, such as the ability to completely unlink your content from the formatting, very flexible layout tools and a veritable smorgasbord of packages to do everything from change the colour of your text to allow you to programmatically create plots...

Rainbow in a Box

June 23, 2015

Yesterday, I helped out at the physics department with a visit for a local sixth form. The basic idea was that in the morning the groups of students got a tour around the building and then in the afternoon they would get involved in a load of experiments. I was assigned the job of looking after...

Radiative Transfer in Planetary Atmospheres: An Overview

January 1, 2015

A little while ago I got carried away on a little post which discussed a really cool little bit of physics called radiative transfer. As I said then, radiative transfer is a technique that you can use to study how energy, in the form of electromagnetic radiation, moves through material. In that post, which you can...

Dust in the Ointment

October 18, 2014

It’s nice every now and then to have a slight reminder why your work is valuable. At the moment I’m part of a research team, working in the astrophysics department at the University of Exeter,  that are studying dust. I know exactly what you’re thinking, how interesting can dust be? The truth is that interstellar...

The Basics of Radiative Transfer

April 28, 2014

It’s deep in exam season for me at the moment, which means that if you try talking to me, chances are that I’ll have my head in a book. I talked a while back about solving radiative transfer problems with Monte Carlo methods, but I never actually went very far into how radiative transfer works....

Gambling with Statistics – Monte Carlo Methods

July 20, 2013

Hey all! In my recent work I’ve been using numerical simulations involving radiative transfer, which basically  means transferring energy via radiation such as light; in the form of photon packets. The way these simulations are run is via a method known quite widely in the physics world called ‘Monte Carlo Methods’. It took me a...
