Decisive evidence for a global cosmic-ray feature in gamma-ray data
Fernando Valenciano, Pedro De la Torre Luque, Daniele Gaggero +1
We analyze 17 years of Fermi-LAT data to study the diffuse -ray emission along the Galactic plane and its connection to cosmic-ray (CR) propagation. Accounting for correlated in…

The Impact of Star Formation Histories on the Inner Dark Matter Density Slopes of Galaxies
Jorge Sarrato-Alós, James Bullock, Arianna Di Cintio +3
Aims. We aim to investigate the connection between star formation histories (SFHs) and the inner dark matter density profiles of simulated galaxies. In particular, we test whether…

Cored galaxies in cuspy dark matter halos
Fernando Valenciano, Jorge Martin Camalich, Arianna Di Cintio +4
We investigate constraints on the inner stellar density profile from photometric data of dwarf spheroidal and ultra-faint dwarf galaxies. Our aim is to clarify under what condition…
