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…
Feedback Processes in the Early Universe
A. Ferrara, B. Ciardi, S. Marri +1
Feedback effects due to massive stars and supernovae in the first objects are shown to strongly regulate both galaxy formation/evolution and the reionization process. Here we revie…
Intergalactic H_2 Photodissociation and the Soft UV Background Produced by Population III Objects
Benedetta Ciardi, Andrea Ferrara, Tom Abel
We study the effects of the ionizing and dissociating photons produced by PopIII objects on the surrounding intergalactic medium. We find that the typical size of a H_2 photodissoc…
