Gamma-ray bursts reveal the history and faint contributors of cosmic reionization
Jing-Meng Hao, Paolo Cassata, Zhen-Ya Zheng +5
Star-forming galaxies are generally believed to be the main drivers of cosmic reionization. However, the relative contributions of bright and faint galaxies to this process remain…
Primordial black holes as supermassive black holes seeds
Francesco Ziparo, Simona Gallerani, Andrea Ferrara
The presence of supermassive black holes (SMBHs, ) in the first cosmic Gyr () challenges current models of BH formation and evoluti…
Simulating cosmic metal enrichment by the first galaxies
A. Pallottini, A. Ferrara, S. Gallerani +2
We study cosmic metal enrichment via AMR hydrodynamical simulations in a (10 Mpc/h) volume following the Pop III-Pop II transition and for different Pop III IMFs. We have analy…
Metals and ionizing photons from dwarf galaxies
S. Salvadori, E. Tolstoy, A. Ferrara +1
We estimate the potential contribution of M < 10^9 Msun dwarf galaxies to the reionization and early metal-enrichment of the Milky Way environment, or circum-Galactic Medium. Our a…
The infant Milky Way
Stefania Salvadori, Andrea Ferrara
We investigate the physical properties of the progenitors of today living Milky Way-like galaxies that are visible as Damped Lya Absorption systems and Lya Emitters at higher redsh…
First stars in Damped Lyman Alpha systems
Stefania Salvadori, Andrea Ferrara
In order to characterize Damped Lyman Alpha systems (DLAs) potentially hosting first stars, we present a novel approach to investigate DLAs in the context of Milky Way (MW) formati…
Mining the Galactic Halo for Very Metal-Poor Stars
S. Salvadori, A. Ferrara, R. Schneider +2
We study the age and metallicity distribution function (MDF) of metal-poor stars in the Milky Way halo as a function of galactocentric radius by combining N-body simulations and se…
