High energy astrophysics and early Universe
BBN Nucleosynthesis
The research team “Cosmology and High Energy Astrophysics” (COSMOH) is involved in the study of astrophysical sources of high energy radiation, especially gamma-ray bursts and quasars, and the use of these bright objects as tracers of the distant Universe.
Our theoretical activities follow two main directions:
– Modelling astrophysical sources of high-energy radiation.
– Cosmology: big-bang nucleosynthesis (BBN) and the cosmic evolution of baryons.
Our observational activities are various :
–Search and study of sources at high redshift.
– Spectroscopy of distant sources to study gas along the line of sight.
