Directly tracking the re-brightening of a supermassive black hole accretion disk
R. Middei, E. Nardini, C. Done +12
Accretion onto supermassive black holes powers the most luminous persistent sources in the Universe, the so-called active galactic nuclei, whose emission is characterized by two di…
UV background fluctuations traced by metal ions at
L. Graziani, A. Maselli, U. Maio
Here we investigate how LyC-opaque systems present in the intergalactic medium at can distort the spectral shape of a uniform UV background (UVB) through radiative tran…
Galaxy formation with radiative and chemical feedback
L. Graziani, S. Salvadori, R. Schneider +3
Here we introduce GAMESH, a novel pipeline which implements self-consistent radiative and chemical feedback in a computational model of galaxy formation. By combining the cosmologi…
CRASH3: cosmological radiative transfer through metals
L. Graziani, A. Maselli, B. Ciardi
Here we introduce CRASH3, the latest release of the 3D radiative transfer code CRASH. In its current implementation CRASH3 integrates into the reference algorithm the code Cloudy t…
Prospects for detecting the 21cm forest from the diffuse intergalactic medium with LOFAR
B. Ciardi, P. Labropoulos, A. Maselli +20
We discuss the feasibility of the detection of the 21cm forest in the diffuse IGM with the radio telescope LOFAR. The optical depth to the 21cm line has been derived using simulati…
The effect of intergalactic helium on hydrogen reionisation: implications for the sources of ionising photons at z > 6
B. Ciardi, J. S. Bolton, A. Maselli +1
We investigate the effect of helium on hydrogen reionisation using a hydrodynamical simulation combined with the cosmological radiative transfer code CRASH. The simulations are run…
