A small website
This is the personal website of fergus: a place to put all the things I used to share on public social media. Here you'll find some of my research things, some music, art, a little writing, and various other, possibly interesting, probably useless things.

Physics software things:
At the end of this page is the index for my infrequently updated blog. Other things on this site include:
Elsewhere on the web:
- Sourcehut ~fjebaker, for personal projects.
- Codeberg fjebaker, miscellaneous.
- On gemini:// under gemlog.cosroe.com, though not as often as I would like to be.
- Mastodon @fergus@cosroe.com.
- Then reluctantly GitHub @fjebaker, mainly for work.

About
(he/him)
I'm an astrophysics post-doc at Durham University in the group of Adam Ingram, where my focus is on reverberation lags around accreting black holes. In my spare time, I'm an open source and privacy advocate, and like to tinker with things that flip bits or make sounds.
I previously completed my PhD in astrophysics at the University of Bristol, under the supervision of Andy Young. My thesis is on modelling general relativistic effects in spectral processes related to the black hole X-ray corona.
My opinions are my own.

Older blog posts can be found on fjebaker.github.io/blog. They will at some point be made available here, but I am using my own mathematics rendering system that I need to transcribe the LaTeX to. There will be a blog post about that in the future too.
