Chirp – An App for Monitoring Gravitational Wave Alerts

November 1, 2019

I’m absolutely delighted to announce that a spare-time project I have been involved with for the best part of a year has finally been released. Enter Chirp – an app to help you monitor gravitational wave alerts. The app is being officially released to coincide with the start of O3b, the second part of the...

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...

Web Development for Physicists

February 17, 2018

I’m fortunate enough to be sitting at the intersection of two disparate fields which are rapidly hurtling towards each other. More than ever, it’s becoming important to publicise you and your research, whether you’re in academia or in the private sector. Sooner or later, this is likely going to mean you’re going to requiring some...

Outreach

October 23, 2017

YouTube I have produced outreach videos for the Physics at Exeter YouTube channel. To see some of the videos I have worked on, please see this page. Chirp Chirp is a app for the web, iOS and Android that can be used to keep track of gravitational wave alerts. It was developed as a collaboration...

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...

Once Again, With More Soul

March 22, 2016

In my free time of late, I’ve been busy beavering away on my latest website. This one has taken a few weeks to perfect and hone but this is the brand new website for my band Soul Traders. This has been coming for a little while, and when you see the old site you’ll understand why. It’s...

Using Wintersmith to Make Awesome Static Websites

December 3, 2015

For the last month or so, I’ve been deeply investing my spare time into writing a website for a conference, the UK Exoplanet Community Meeting 2016, or UKEXOM 2016 for short. Early on we decided that the best way to host it would probably be to use Amazon’s pretty nifty S3 service. This comes with...

My Research

May 26, 2015

My research interests span a wide variety of topics. My masters research focussed on studies of extinction and interstellar dust. Throughout my PhD, my work focussed on observational studies of the evolution of stellar clusters, low-mass stars and characterisation of exoplanet host stars. These studies have made extensive use of cutting edge observational data from...

Modeling Atmospheres with the Unified Model

February 24, 2015

In my last couple of posts I’ve been going through some of the basic principles of fluid mechanics. From some of the basic approximations that make the equation possible to analytically solve in this post, to some more specialised theory in the context of planetary systems in this post. In these posts we’ve been slowly...

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...

Mini Javascript Hackathon – Tix Clock

July 31, 2013

I’ve spent a lot of time recently writing C++, Python and Shell Script. These languages are great, but I fancied taking a break from them to go back to my old stomping ground. Earlier today I remembered about the existence of a cool little, almost completely useless, piece of geek tech known as the Tix...

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...
