Robust PCA and MIC statistics of baryons in early mini-haloes
R. S. de Souza, U. Maio, V. Biffi +1
We present a novel approach, based on robust principal components analysis (RPCA) and maximal information coefficient (MIC), to study the redshift dependence of halo baryonic prope…
The first analytical expression to estimate photometric redshifts suggested by a machine
A. Krone-Martins, E. E. O. Ishida, R. S. de Souza
We report the first analytical expression purely constructed by a machine to determine photometric redshifts () of galaxies. A simple and reliable functional form is…
Pushing the limits of the Gaia space mission by analyzing galaxy morphology
A. Krone-Martins, C. Ducourant, R. Teixeira +6
The ESA Gaia mission, to be launched during 2013, will observe billions of objects, among which many galaxies, during its scanning of the sky. This will provide a large space-based…
Detectability of the First Cosmic Explosions
R. S. de Souza, E. E. O. Ishida, J. L. Johnson +2
We present a fully self-consistent simulation of a synthetic survey of the furthermost cosmic explosions. The appearance of the first generation of stars (Population III) in the Un…
Constraints on Warm Dark Matter models from high-redshift long gamma-ray bursts
Rafael S. de Souza, Andrei Mesinger, Andrea Ferrara +3
Structures in Warm Dark Matter (WDM) models are exponentially suppressed below a certain scale, characterized by the dark matter particle mass, . Since structures form h…
