Measuring line-of-sight shear with Einstein rings
Today I released a paper written in collaboration with Pierre Fleury, Julien Larena and Matteo Martinelli on how we can measure line-of-sight shear from Einstein rings. But what is line-of-sight shear, and why are we interested in measuring it in the first place? To answer these questions, let’s review the phenomenon of strong gravitational lensing.…

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!

From Madrid to the Cotswolds by train
I can’t pretend to enjoy flying. It’s noisy, stressful and horrendously bad for the environment. On my last journey to Madrid, I took the ferry from Portsmouth to Santander and the train on from there. The ferry crossing itself took about thirty hours spread over two nights (with an evening departure and an early morning…

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…

Visa application
I am starting to regret this resolution of writing a blog post every day for thirty days. I’ve already missed a few days so the thirty will no longer be consecutive and perhaps my days are not as interesting as I anticipated. I suppose that’s mainly because this week has been a week of admin…
