The howling Universe
Before I moved from IFT to IPhT, I filmed a video all about what standard sirens are and why they’re useful for cosmology. The video is now on Youtube, in English with Spanish subtitles. Take a look!

Implicit none
The first programming language I ever learned was Fortran. And before you ask, no, I’m not seventy years old. It just so happened that during my undergraduate degree, I took two courses on numerical methods for physics which were taught in Fortran, and for good reason: Fortran is still one of the best languages to […]

My first N months as a postdoc (where 0 < N < 12)
How long have I been a postdoc? It’s a little difficult to quantify. I finished my PhD thesis in December 2020, and submitted it in January 2021. I passed my viva in February 2021. I spent a few months climbing the walls waiting for my Spanish visa, and trying to do research at the same […]

The road (back) to Madrid
On Friday last week I signed my contract and started my job as a postdoctoral researcher at the IFT in Madrid. It feels extremely good to type that. I have also been waiting a very long time to write this post. I was offered this job on the 12th of April 2020 — when the […]

Using a Jupyter notebook to make presentation slides
TL;DR: Open a blank Jupyter notebook. Add a cell and convert it to Markdown (either esc + m) or by using the drop down menu at the top of the notebook. Add your text, equation or image to the cell (images can be added via the edit menu, though some HTML tags may be needed […]

Running, paper revisions, talk writing
I started this morning in unusually energetic fashion, by going for a run before starting work. It was a bit chilly but the sky was clear blue and the sun was shining. The birds were singing and the blackthorn blossom has topped the newly green trees and hedges with a creamy white glaze. The daffodils […]

Philosophy and cosmology
I’ve decided it’s time to improve the consistency of my writing and practice makes perfect, as they say. So, starting from today, I’m going to a write a blog post every day for thirty days (excluding weekends and holidays). By my calculation, this means the last post in the thirty day sequence will come on […]

My PhD viva
In this post, I’ll discuss how I prepared for my PhD viva exam in cosmology, what the viva itself was like and what happened next. I submitted my PhD thesis on the 4th of January 2021 (which also happened to be my birthday) and had my viva exam on the 3rd of February. This is […]

Writing my PhD thesis
How do you write a PhD thesis? This question sounds like the start of the old joke: “How do you eat an elephant? One piece at a time”. A PhD thesis is a document which must explain, summarise and defend three or more years of research in your chosen field, often running to 40,000 words […]

Thesis off-cuts: the reproducibility crisis in cosmology
As we frequently hear1, we’re now in the precision era of cosmology. What this really means is that we’re in the era of measuring things really well, and we’re getting really good at measuring things because we keep building ever more enormous and powerful telescopes. I remember attending the STFC Introductory Summer School on Astronomy […]
