The imprint of cosmological non-Gaussianities on primordial structure formation
Umberto Maio, Sadegh Khochfar
We study via numerical N-body/SPH chemistry simulations the effects of primordial non-Gaussianities on the formation of the first stars and galaxies, and investigate the impact of…
Radiative feedback and cosmic molecular gas: numerical method
Margarita Petkova, Umberto Maio
We present results from self-consistent 3D numerical simulations of cosmic structure formation with a multi-frequency radiative transfer scheme and non-equilibrium molecular chemis…
Gas distribution, metal enrichment, and baryon fraction in Gaussian and non-Gaussian universes
Umberto Maio
We study the cosmological evolution of baryons in universes with and without primordial non-Gaussianities via (large scale) N-body/hydrodynamical simulations, including gas cooling…
Population III stars and the Long Gamma Ray Burst rate
M. A. Campisi, U. Maio, R. Salvaterra +1
Because massive, low-metallicity population III (PopIII) stars may produce very powerful long gamma-ray bursts (LGRBs), high-redshift GRB observations could probe the properties of…
Baryon history and cosmic star formation in non-Gaussian cosmological models: numerical simulations
Umberto Maio, Francesca Iannuzzi
We present the first numerical, N-body, hydrodynamical, chemical simulations of cosmic structure formation in the framework of non-Gaussian models. We study the impact of primordia…
