Simulating high-z Gamma-ray Burst host galaxies
R. Salvaterra, U. Maio, B. Ciardi +1
We investigate the nature of high-z host galaxies of long Gamma-Ray Bursts (LGRBs) by means of state-of-the-art numerical simulations of cosmic structure formation and evolution of…
Simulating the assembly of galaxies at redshifts z = 6 - 12
Pratika Dayal, James S. Dunlop, Umberto Maio +1
We use state-of-the-art simulations to explore the physical evolution of galaxies in the first billion years of cosmic time. First, we demonstrate that our model reproduces the bas…
Dark Matter Halo Environment for Primordial Star Formation
Rafael S. de Souza, Benedetta Ciardi, Umberto Maio +1
We study the statistical properties (such as shape and spin) of high-z halos likely hosting the first (PopIII) stars with cosmological simulations including detailed gas physics. I…
Non-Gaussianities, early Universe, and GRBs. Tracing the primeval state of the Universe with number counts of Gamma-Ray Bursts
Umberto Maio
We investigate the effects of primordial non-Gaussianities in the primordial Universe on the baryonic structure formation process. By relating the cosmic star formation rate in Gau…
Counts of high-redshift GRBs as probe of primordial non-Gaussianities
Umberto Maio, Ruben Salvaterra, Lauro Moscardini +1
We propose to use high-redshift long -ray bursts (GRBs) as cosmological tools to constrain the amount of primordial non-Gaussianity in the density field. By using numerical, N-b…
Effect of Intergalactic Medium on the Observability of Lyman Alpha Emitters during Cosmic Reionization
Akila Jeeson-Daniel, Benedetta Ciardi, Umberto Maio +3
We perform a systematic study of how the inhomogeneities in the Inter-Galactic Medium (IGM) affect the observability of Lyman Alpha Emitters (LAEs) around the Epoch of Reionization…
