The effect of minihaloes on cosmic reionization
B. Ciardi, E. Scannapieco, F. Stoehr +3
One of the most debated issues in the theoretical modeling of cosmic reionization is the impact of small-mass gravitationally-bound structures. We carry out the first numerical inv…
Constraints on the IMF of the first stars
R. Schneider, R. Salvaterra, A. Ferrara +1
Motivated by theoretical predictions that first stars were predominantly very massive, we investigate the physics of the transition from an early epoch dominated by massive Pop III…
Reionization History from Coupled CMB/21cm Line Data
R. Salvaterra, B. Ciardi, A. Ferrara +1
We study CMB secondary anisotropies produced by inhomogeneous reionization by means of cosmological simulations coupled with the radiative transfer code CRASH. The reionization his…
The Radio to Infrared Emission of Very High Redshift Gamma-Ray Bursts: Probing Early Star Formation through Molecular and Atomic Absorption Lines
Susumu Inoue, Kazuyuki Omukai, Benedetta Ciardi
We evaluate the broadband afterglow emission of very high redshift gamma-ray bursts (GRBs) using standard relativistic blastwave models with both forward and reverse shock componen…
