White dwarfs as Advanced Physics laboratories: the axion case

White dwarfs as Advanced Physics laboratories: the axion case

White dwarfs as Advanced Physics laboratories: the axion case The shape of the luminosity function of white dwarfs (WDLF) is sensitive to the characteristic cooling time and, therefore, it can be used to test the existence of additional sources or sinks of energy such...

Induced gravitational waves in general backgrounds

Induced gravitational waves in general backgrounds Gravitational waves are unavoidably generated at second order in cosmological perturbation theory. In some cases, such induced gravitational waves might be observable by future space-based gravitational waves...
Black Hole in Globular Clusters

Black Hole in Globular Clusters

Black Hole in Globular Clusters Globular clusters (GCs) are the outcome of the earliest phases of star and galaxy formation in the Universe. Their high densities foster the formation and hardening of binary black holes (BHs) that can merge via gravitational wave...
