Cosmic Radiative Feedback from Reionization
R. Salvaterra, C. Burigana, R. Schneider +3
We explore the effect of cosmic radiative feedback from the sources of reionization on the thermal evolution of the intergalactic medium. We find that different prescriptions for t…
The Spatial Distribution of the Galactic First Stars I: High-Resolution N-body Approach
Evan Scannapieco, Daisuke Kawata, Chris B. Brook +3
We study the spatial distribution of Galactic metal-free stars by combining an extremely high-resolution (7.8 X 10^5 solar masses per particle) Cold Dark Matter N-body simulation o…
Extragalactic Background Light: new constraints from the study of the photon-photon absorption on blazar spectra
M. Mapelli, R. Salvaterra, A. Ferrara
The study of the Extragalactic Background Light (EBL) is crucial to understand many astrophysical problems (as the formation of first stars, the evolution of galaxies and the role…
Feedback Processes at Cosmic Dawn
A. Ferrara, R. Salvaterra
The consequences of energy injection associated with stellar activity in galaxies have been often referred to as ``feedback effects''. Assessing the detailed physics and the role o…
On the Direct Detectability of the Cosmic Dark Ages: 21-cm Emission from Minihalos
Ilian T. Iliev, Paul R. Shapiro, Andrea Ferrara +1
In the standard Cold Dark Matter (CDM) theory of structure formation, virialized minihalos (with T_vir}<10^4 K) form in abundance at high redshift (z>6), during the cosmic ``dark a…
Physical Processes at Cosmic Dawn
Andrea Ferrara
In this summary paper I will focus on the four main topics discussed at this Conference: (i) First luminous sources in the universe, (ii) Reionization, (iii) Intergalactic medium a…
