Research interests: Neutrino Cosmology, CMB physics, Boltzmann codes, Dark Matter

Biography:

I got my PhD from Aarhus University in 2012 and did my first postdoc at the EPFL in Switzerland before joining the ICG in 2014. I am interested in a broad range of subjects ranging from the production of sterile neutrinos in the early Universe to CMB physics and cosmological constraints on decaying Dark matter.

Research in cosmology today requires numerical tools, and part of my time has been spent on developing those. I am the main author of the code LASAGNA which solves the Quantum Kinetic Equations relevant for sterile neutrino production, and I am a co-author of the Boltzmann code CLASS (https://github.com/lesgourg/class_public) which among other things compute the theoretical expectation for the CMB power spectra as well as the linear matter power spectrum. Recently I have started working on a few projects involving the second-order CMB code SONG as well.

  • The Intrinsic Matter Bispectrum on 15th Aug 2016 2:00:pm Upcoming large scale structure surveys will map the structure of the Universe on very large scales where General Relativistic (GR) e”ects become important. In order to extract information from these surveys, we must have a fast and accurate analytic model. This is well known on small scales where the precision of Newtonian N-body codes is...
