Systematic Uncertainties In Constraining Dark Matter Annihilation From The Cosmic Microwave Background
Silvia Galli, Tracy R. Slatyer, Marcos Valdes +1
Anisotropies of the cosmic microwave background (CMB) have proven to be a very powerful tool to constrain dark matter annihilation at the epoch of recombination. However, CMB const…
The nature of dark matter from the global high redshift HI 21 cm signal
Marcos Valdés, Carmelo Evoli, Andrei Mesinger +2
We study the imprint of dark matter (DM) annihilation on the global 21 cm signal from the Dark Ages to Cosmic Reionization. Motivated by recent observations, we focus on three DM c…
Particle energy cascade in the Intergalactic Medium
Marcos Valdes, Carmelo Evoli, Andrea Ferrara
We study the development of high energy (E_in < 1TeV) cascades produced by a primary electron of energy E_in injected into the intergalactic medium (IGM). To this aim we have devel…
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…
