Thibaut Louis
I am a CNRS researcher, working in Laboratoire de Physique des 2 Infinis Irene Joliot Curie. My research is in cosmology, studying the origins and evolution of the Universe. My major projects are the Atacama Cosmology Telescope and the Simons Observatory. These experiments aim at measuring the temperature and polarisation of the cosmic microwave background, the thermal afterglow of the Big Bang.
I got my PHD from Oxford University under the supervision of Joanna Dunkley. I also spent two years as a post-doc at Institut Astrophysique de Paris working in the group of Joseph Silk. On this page you can find a (slightly outdated) CV, and some of my works. You can contact me by sending an email to thibaut.louis (at) cnrs (dot) fr.

A list of my publications can be found on arXiv or Google Scholar.
Codes
All the codes I have written are in the public domain, some of them can be accessed on my Github, others on the Simons Observatory Github.
Students
Phd students: Adrien La Posta, I also acted as cosupervisor for Rupert Allison and Sylvain Vanneste.
Master students: Adam Soussana and Magdy Morshed
Lectures notes
I'm teaching "Statistical methods for Cosmology" at the Euclid Summer school (french) (notes), and Cosmology of the Dark Universe (part1, part2, TD, videos )
Press (French)
I was involved with the preparation of the press release of the 2020 ACTPol results (French version). In particular, we have presented a new measurement of the age of the Universe. I was also interviewed about it in Science et Avenir and in "Le reportage du jour" de la methode scientifique (france culture). I was also involved in the preparation of the press release for the 2023 AdvACT results, with the most precise map of CMB lensing
Youtube
I gave a talk at IAP on the H0 tension that was recorded (YouTube).
Here is also a trailer I have made for PSplay (YouTube), an interactive power spectrum code developped for the Simons Observatory (with Xavier Garrido and Sigurd Naess), the code is available on Github.
