Cosmic reionization by primordial cosmic rays
(EDP Sciences, 2014-10)
Context. After the so-called cosmic recombination, the expanding universe entered into a period of darkness since most of the matter was in a neutral state. About a billion years later, however, the intergalactic space was ...
Model for Population III microquasars
(EDP Sciences, 2019-09)
Current simulations indicate that the first stars were formed predominantly in binary systems. The study of the contribution of the first accreting binary systems to the reionization and heating of the intergalactic medium ...
Population III microquasars

The imprint of reionization on the star formation histories of dwarf galaxies
(Wiley Blackwell Publishing, Inc, 2015-04)
We use a compilation of star formation histories (SFHs) and cosmological simulations to explore the impact of cosmic reionization on nearby isolated dwarf galaxies. Nearby dwarfs show a wide diversity of SFHs; from ancient ...
Probing the stellar initial mass function with high-z supernovae
(Oxford University PressOxford, 2014)
The first supernovae (SNe) will soon be visible at the edge of the observable universe, revealing
the birthplaces of Population III stars. With upcoming near-infrared missions, a broad analysis
of the detectability of ...
Population III microquasars
(World Scientific, 2018-07)
We present the first results obtained in the elaboration of a complete model of a microquasar where the donor star is from Population III. These stars do not produce stellar winds so we consider that the mass loss is due ...
On the lack of correlation between [O III ]/[O II ] and Lyman continuum escape fraction
(Wiley Blackwell Publishing, Inc, 2019-03)
We present the first results of our pilot study of eight photometrically selected Lyman-continuum (LyC) emitting galaxy candidates from the COSMOS field and focus on their optical emission line ratios. Observations were ...
