Standard sirens, Cobaya and Beethoven’s 9th: Madrid week two

As of tomorrow, I'll have been in Madrid for two weeks! Time really does fly. The weather is still freezing and there's fresh snow on the hills behind campus (as you can hopefully see in the header image, which I took on my commute this morning). This week I made a proper start on the …

Studying abroad in Madrid: the first week

Hello! If you're reading my website for the first time, I'm a third year PhD student from the University of Portsmouth, working on testing and constraining models of interacting dark energy. If you want to know more about my research, you can click here for an overview and here for some more in-depth information. However, …

Constraints on the interacting vacuum — geodesic CDM scenario

At the very end of February, I published my first paper. In this post, I want to provide a brief, non-technical overview of what we* were doing in this work and the results we found. The manuscript is currently under review at MNRAS but you can view the preprint here: http://www.arxiv.org/abs/1902.10694. The aim of this …

Surviving burn out and the post-paper blues

I published my first paper at the end of February. I won't beat about the bush: writing this paper was exhausting. I'd had unrealistic expectations for how quickly I'd get publishable results, and consequently every delay to our draft felt like a disaster. At first we were going to be ready by July (2018). Then …

A collaborative week in Leiden

I spent the past week at the Lorentz Institute, the theoretical cosmology part of the physics community at Leiden University. My collaborators there are fellow members of CANTATA, an EU COST-Action that is mainly focused on creating and testing alternative theories of gravity, and I was awarded my second STSM (short-term scientific mission) by CANTATA …

Slow progress– but progress nonetheless

This week I'm in the Netherlands, visiting colleagues at the Lorentz Institute at Leiden University. Leiden is a beautiful place-- a scaled-down, tourist-free version of Amsterdam-- and the institute is nice too. It's the oldest theoretical physics institute in the Netherlands and has played host to many greats of the field, including Ehrenfest, Fermi and …
