The formation of the first galaxies in the Universe is the new frontier of both galaxy formation and reionization studies. In fact, we will soon directly...
CharlaA fierce new challenge: unveil the connection between the first galaxies and reionization
PublicaciónA Forecast of the Sensitivity on the Measurement of the Optical Depth to Reionization with the GroundBIRD Experiment
We compute the expected sensitivity on measurements of optical depth to reionization for a ground-based experiment at Teide Observatory. We simulate polarized...
CharlaA Hundred Years after: Gravitational Waves, Black Holes, GW150914
A discussion of the first observation ever of gravitational waves. Present detectors, future detectors, and the perspectives for gravitational wave astronomy.
PublicaciónA Long Time Ago in a Galaxy Far, Far Away: A Candidate z 12 Galaxy in Early JWST CEERS Imaging
We report the discovery of a candidate galaxy with a photo-z of z ~ 12 in the first epoch of the James Webb Space Telescope (JWST) Cosmic Evolution Early...
PublicaciónA lower bound on intergalactic magnetic fields from time variability of 1ES 0229+200 from MAGIC and Fermi/LAT observations
Context. Extended and delayed emission around distant TeV sources induced by the effects of propagation of γ ray s through the intergalactic medium can be used...
PublicaciónA mean redshift of 2.8 for Swift gamma-ray bursts
The exceptionally high luminosities of gamma-ray bursts (GRBs), gradually emerging as extremely useful probes of star formation, make them promising tools for...
CharlaA multi-wavelength approach to the properties of Extremely Red Galaxy populations: star formation rate and mass densities, AGN and dust content, and morphology
In this talk, I will cover our contribution to the study of extremely red galaxy (ERG) populations presenting a multi-wavelength analysis of these objects...
PublicaciónAn ionized superbubble powered by a protocluster at z = 6.5
We show herein that a proto-cluster of Ly α emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionizing continuum...
PublicaciónAnisotropy of the cosmic microwave background and primordial nucleosynthesis: observational pillars of big bang cosmology.
The authors review recent results on the anisotropy of the cosmic microwave background and on primordial abundances of light-elements. These two key fields of...
