Light Dark Matter: A Common Solution to the Lithium and Problems
Jailson Alcaniz, Nicolás Bernal, Antonio Masiero +1
Currently, the standard cosmological model faces some tensions and discrepancies between observations at early and late cosmological time. One of them concerns the well-known …
Self-interacting dark matter without prejudice
Nicolás Bernal, Xiaoyong Chu, Suchita Kulkarni +1
The existence of dark matter particles that carry phenomenologically relevant self-interaction cross sections mediated by light dark sector states is considered to be severely cons…
Ultraviolet Freeze-in and Non-Standard Cosmologies
Nicolás Bernal, Fatemeh Elahi, Carlos Maldonado +1
A notable feature of UV freeze-in is that the relic density is strongly dependent on the highest temperatures of the thermal bath, and a common assumption is that the relevant 'hig…
Reconstructing Non-standard Cosmologies with Dark Matter
Paola Arias, Nicolás Bernal, Alan Herrera +1
Once dark matter has been discovered and its particle physics properties have been determined, a crucial question rises concerning how it was produced in the early Universe. If its…
Primordial Gravitational Waves in Nonstandard Cosmologies
Nicolás Bernal, Fazlollah Hajkarim
Assuming that inflation is followed by a phase where the energy density of the Universe is dominated by a component with a general equation of state, we evaluate the spectrum of pr…
