Description
The phenomenon of cosmological gravitational particle production (CGPP) occurs during and after inflation as quantum fields “feel” the cosmological expansion are excited out of their ground state. CGPP is a compelling and minimal explanation for the origin of dark matter, which might only interact gravitationally, as well as other cosmological relics. In this talk, I’ll discuss some recent developments in the study of dark matter from CGPP. This includes: interference fringes in the dark matter energy spectrum, a recent study of CGPP for massive spin-2 particles, and observational probes.
