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...

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...

STFC Summer School 2015

September 2, 2015

And so it has become time for my first trip as (nearly) a postgraduate. Several train journeys, and a lot of paper reading, later I ended up in the beautiful city of Cardiff for the STFC Summer School in Astronomy. This is essentially a conference for new STFC funded postgraduates in astronomy and space science to come...

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...

The Fluid Mechanics of Planetary Atmospheres

February 16, 2015

In my last post I went over a really powerful bit of physics called fluid mechanics, which describes the flow of fluid through a system. The main equation in this framework is the momentum equation; the Navier-Stokes equation.This equation is nye on impossible to solve analytically in it’s full grotesque glory, so in the last post I discussed some of...

Some Fluid Mechanics Basics

January 23, 2015

At the moment I’m intently studying fluid mechanics for an exam on planetary science. As you may have guessed, the fluid mechanics in question is for modelling planetary atmospheres, but the mathematics is universally applicable. I’ve wanted to learn fluid mechanics for many years so I thought I’d just go through some of the basics...

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...
