Metal enrichment signatures of the first stars on high-z DLAs
Q. Ma, U. Maio, B. Ciardi +1
We use numerical N-body hydrodynamical simulations with varying PopIII stellar models to investigate the possibility of detecting first star signatures with observations of high-re…
Distortions of the Cosmic Microwave Background through cooling lines during the epoch of Reionization
Carlos Hernandez-Monteagudo, Umberto Maio, Benedetta Ciardi +1
By using N-body hydrodynamical cosmological simulations in which the chemistry of major metals and molecules is consistently solved for, we study the interaction of metallic fine-s…
The First Stars in the Universe
U. Maio
The basic processes of the formation of the first stars in the primordial Universe are outlined and the implications for cosmological structure formation discussed. By employing th…
PopIII signatures in the spectra of PopII/I GRBs
Q. Ma, U. Maio, B. Ciardi +1
We investigate signatures of population III (PopIII) stars in the metal-enriched environment of GRBs originating from population II-I (PopII/I) stars by using abundance ratios deri…
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…
