The first carbon-enhanced metal-poor star found in the Sculptor dwarf spheroidal
Asa Skuladottir, Eline Tolstoy, Stefania Salvadori +4
The origin of carbon-enhanced metal-poor (CEMP) stars and their possible connection with the chemical elements produced by the first stellar generation is still highly debated. In…
Decoding the stellar fossils of the dusty Milky Way progenitors
Matteo de Bennassuti, Raffaella Schneider, Rosa Valiante +1
We investigate the metallicity distribution function (MDF) in the Galactic halo and the relative fraction of Carbon-normal and Carbon-rich stars. To this aim, we use an improved ve…
High-redshift quasars host galaxies: is there a stellar mass crisis?
Rosa Valiante, Raffaella Schneider, Stefania Salvadori +1
We investigate the evolutionary properties of a sample of quasars at 5<z<6.4 using the semi-analytical hierarchical model GAMETE/QSOdust. We find that the observed properties of th…
Initial mass function of intermediate mass black hole seeds
A. Ferrara, S. Salvadori, B. Yue +1
We study the Initial Mass Function (IMF) and host halo properties of Intermediate Mass Black Holes (IMBH, 10^{4-6} Msun) formed inside metal-free, UV illuminated atomic cooling hal…
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…
The origin of the Far-infrared continuum of z ~ 6 quasars: a radiative transfer model for SDSS J1148+5251
Raffaella Schneider, Simone Bianchi, Rosa Valiante +2
We investigate the origin of the FIR continuum of SDSS J1148+5251, using it as a prototype for the more general class of high-luminosity high-redshift QSOs. We run the radiative tr…
