Visit of Laura Bernard
Laura Bernard visited us in the beginning of April 2025. Thank you for the visit and seminar Laura!
Cosmology
Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.
For our latest developments/activities in this area, please see the listing below.

Temperature evolution in the Early Universe and Freeze-in at stronger coupling
Speaker
Catarina Cosme (University of Coimbra)
Event date
Venue
Hybrid: Sala Sousa Pinto and Zoom
Event type
In this talk, I will discuss the freeze-in dark matter production mechanism at low reheating temperatures. The process is Boltzmann-suppressed if the dark matter mass is above the reheating temperature, and, in this case, the coupling to the thermal bath has to be significant to account for the observed dark matter relic density.
