Building the Light Pollution Matrix

February 9, 2024

Earlier this week, I had the privilege of recording an episode of a Restoring Darkness podcast with Michael Colligan and Mark Baker. The topics of our conversation ranged from light pollution activism, the role of the lighting industry in solving light pollution, and how we at the Environment and Sustainability Institute and Departments of Physics...

Chirp has a New Home

October 7, 2023

At the end of 2019, I posted about a little app that my colleagues and the University of Birmingham and I had been working on called Chirp — a web and iOS app for keeping track of the latest gravitational wave alerts. The COVID-19 pandemic shut down LIGO, and Chirp, but now it’s coming back...

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...

About Me

August 12, 2018

I am a Research Fellow at the University of Exeter, currently applying my training in astrophysics to help better understand, and hopefully begin to solve, the pressing ecological crisis caused by artificial light at night (ALAN). I lead the development of our Monte Carlo Radiative Transfer model, whose outputs we correlate with measurements of animal...

XRT-C Dish Mounting Video is Finally Here!

February 8, 2018

This one has been a long time coming. The XRT-C project has likely seemed a little bit quiet of late, but never fear, as there’s always stuff going on in the background, even if it is only me. Ever since the build day in April 2016, I’ve been working on a video of the day...

Bodmin Moor – International Dark Sky Landscape

August 26, 2017

Some time ago, in mid-November last year the XRT-C project, the student radio telescope project based at Caradon observatory in Cornwall, as well as Space Exe, the student society at the University of Exeter that maintains and runs the former, were called upon to play a small part in something truly special; to support an...

What I’ve Been Listening To – December 2016

January 17, 2017

Apologies for the tardiness of the post. I’ve been meaning to get it out for a couple of weeks, but unfortunately I’m pretty apt at procrastination. It’s certainly been a hell of year. What with the various questionable bits of politics, scandals, gates of all varieties and now the first year where the antarctic sea...

What I’ve Been Listening To – November 2016

December 3, 2016

There’s no mistaking it. 2016 is beginning to draw to an oh so welcoming close, not so much with a bang, but more of a turgid death rattle. The nights have drawn in to mid afternoon and the weather is as unpredictable as ever. It’s on evenings like this it’s nice to cuddle up by...

Boldly Going for 50 Years

September 8, 2016

It’s very much not an overstatement to say that I adore Star Trek. Today is a very special for someone who claims this level of adoration for the franchise as it is exactly 50 years old today. Back on September 8th 1966 the first ever episode of Star Trek, The Man Trap, hit the screens...

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...

What I’ve Been Listening To – July 2016

August 1, 2016

Welcome to another great instalment of my regular monthly revelry in auditory excellence. This month’s list is unabashedly short and single minded in its focus. Basically, this will probably go down in history as the ‘Sam finds Christine and the Queens month’. So, with this in mind let’s get going on our helpings for July....

Redesigning XRT-C

July 17, 2016

As some who read this may know I’m involved, well currently the project lead, on the Exeter Radio Telescope at Caradon (XRT-C) project. The idea behind this project is great; to build a professional grade, 4.5m radio telescope in the Cornish country side that can be used by students across the UK. Up until now,...
