The Energy Cascade from Warm Dark Matter Decays
M. Valdés, A. Ferrara
We use a set of Monte Carlo simulations to follow the cascade produced by a primary electron of energy E_in in the intergalactic medium. We choose E_in=3-10 keV as expected from th…

Constraining DM through 21 cm observations
M. Valdes, A. Ferrara, M. Mapelli +1
Beyond reionization epoch cosmic hydrogen is neutral and can be directly observed through its 21 cm line signal. If dark matter (DM) decays or annihilates the corresponding energy…

Radio views of cosmic reionization
M. Valdes, B. Ciardi, A. Ferrara +2
We use numerical simulations of cosmic reionization and radiative processes related to the HI 21 cm emission line to produce synthetic radio maps as seen by next generation radio t…
