Supernova dust yields: the role of metallicity, rotation, and fallback
S. Marassi, R. Schneider, M. Limongi +3
Supernovae (SNe) are considered to have a major role in dust enrichment of high redshift galaxies and, due to the short lifetimes of interstellar grains, in dust replenishment of l…
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…
Radiative transfer of ionizing radiation through gas and dust: stellar source case
Martin Glatzle, Benedetta Ciardi, Luca Graziani
We present a new dust extension to the Monte Carlo radiative transfer code crash, which enables it to simulate the propagation of ionizing radiation through mixtures of gas and dus…
X-ray ionization of the intergalactic medium by quasars
Luca Graziani, B. Ciardi, M. Glatzle
We investigate the impact of quasars on the ionization of the surrounding intergalactic medium (IGM) with the radiative transfer code \texttt{CRASH4}, now accounting for X-rays and…
The Epoch of IGM heating by early sources of X-rays
Marius Berge Eide, Luca Graziani, Benedetta Ciardi +3
Observations of the 21 cm line from neutral hydrogen indicate that an Epoch of Heating (EoH) might have preceded the later Epoch of Reionization (EoR). Here we study the effects on…
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…
