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.
Zeus Sales Moreira successfully defended his Ph.D. thesis on March 31st 2025, which was advised by C. Herdeiro. The committee was composed by Profs. Darío Nunez, Eugen Radu, Alberto Saa and Gonzalmo Olmo and unanimously praised the excellent work of the candidate. Congratulations Zeus and all the best for the future!
The NewFunFiCO mid term meeting took place online on March 20 bringing together many consortium members, to share their experiences with the REA.
Two positions for a Researcher (with Ph.D.) are open within the project Towards Precision Tests of Ultralight Dark Matter with Gravitational Imaging Waves. Application deadline: March 13, 2025. More info in Euraxess.
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.
A meeting of the NewFunFiCO network will take place in Valencia, from 20-22 May 2025. More information can be found here.
