The infrared-luminous progenitors of high-z quasars
Michele Ginolfi, Raffaella Schneider, Rosa Valiante +4
Here we explore the infrared (IR) properties of the progenitors of high-z quasar host galaxies. Adopting the cosmological, data constrained semi-analytic model GAMETE/QSOdust, we s…
"Zombie" or active? An alternative explanation to the properties of star-forming galaxies at high redshift
Francesco Gabriele Saturni, Mattia Mancini, Edwige Pezzulli +1
Star-forming galaxies at high redshift show anomalous values of infrared excess, which can be described only by extremizing the existing relations between the shape of their ultrav…
Chasing the observational signatures of seed black holes at z > 7: candidate observability
Rosa Valiante, Raffaella Schneider, Luca Zappacosta +3
Observing the light emitted by the first accreting black holes (BHs) would dramatically improve our understanding of the formation of quasars at z > 6, possibly unveiling the natur…
The sustainable growth of the first black holes
Edwige Pezzulli, Marta Volonteri, Raffaella Schneider +1
Super-Eddington accretion has been suggested as a possible formation pathway of supermassive black holes (SMBHs) 800 Myr after the Big Bang. However, stellar feed…
On the formation of the first quasars
Rosa Valiante, Bhaskar Agarwal, Melanie Habouzit +1
Observations of the most luminous quasars at redshift z>6 reveal the existence of numerous supermasssive black holes (>10^9 Msun) already in place about twelve billion years ago. I…
Faint progenitors of luminous quasars: why don't we see them?
Edwige Pezzulli, Rosa Valiante, Maria C. Orofino +3
Observational searches for faint active nuclei at have been extremely elusive, with a few candidates whose high- nature is still to be confirmed. Interpreting this lack…
Super-Eddington growth of the first black holes
Edwige Pezzulli, Rosa Valiante, Raffaella Schneider
The assembly of the first super massive black holes (SMBHs) at is still a subject of intense debate. If black holes (BHs) grow at their Eddington rate, they must star…
