Cosmic radiation backgrounds from primordial black holes
Francesco Ziparo, Simona Gallerani, Andrea Ferrara +1
Recent measurements of the cosmic X-ray and radio backgrounds (CXB/CRB, respectively) obtained with Chandra and ARCADE2 report signals in excess of those expected from known source…
Joint QSO-CMB constraints on reionization history
Sourav Mitra, T. Roy Choudhury, Andrea Ferrara
Based on the work by Mitra, Choudhury & Ferrara (2010), we obtain model-independent constraints on reionization from cosmic microwave background (CMB) and QSO absorption line data…
Turbulence in the Intergalactic Medium
Carmelo Evoli, Andrea Ferrara
We study supernova-driven galactic outflows as a mechanism for injecting turbulence in the intergalactic medium (IGM) far from galaxies. To this aim we follow the evolution of a 10…
Constraining cosmic reionization with quasar, gamma ray burst, and Lya emitter observations
S. Gallerani, A. Ferrara, T. R. Choudhury +3
We investigate the cosmic reionization history by comparing semi-analytical models of the Lya forest with observations of high-z quasars and gamma ray bursts absorption spectra. In…
WIMP annihilation effects on primordial star formation
E. Ripamonti, F. Iocco, A. Bressan +3
We study the effects of WIMP dark matter (DM) annihilations on the thermal and chemical evolution of the gaseous clouds where the first generation of stars in the Universe is forme…
