PublicationThe ACS LCID Project. X. The Star Formation History of IC 1613: Revisiting the Over-cooling Problem
We present an analysis of the star formation history (SFH) of a field near the half-light radius in the Local Group dwarf irregular galaxy IC 1613 based on deep...

PublicationThe ACS LCID Project. XI. On the Early Time Resolution of SFHs of Local Group Dwarf Galaxies: Comparing the Effects of Reionization in Models with Observations
The analysis of the early star formation history (SFH) of nearby galaxies, obtained from their resolved stellar populations, is relevant as a test for...

PublicationThe clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: constraints on the time variation of fundamental constants from the large-scale two-point correlation function
We obtain constraints on the variation of the fundamental constants from the full shape of the redshift-space correlation function of a sample of luminous...

TalkThe Cosmic NeuTRIVIA game
In this talk, we shall review the impact of the neutrino properties on the different cosmological observables. We shall also present the latest cosmological...

TalkThe dark and bright sides of massive early-type galaxies
Massive early-type galaxies constitute an ideal test bed to probe our understanding of galaxy formation and evolution. Their high mass, spheroidal morphology...

TalkThe dark side
What's the dark matter made of? Do we have any idea of the kind of particle that should constitute ~85% of the matter content of the Universe? In this talk, I...

PublicationThe First Billion Years project: birthplaces of direct collapse black holes
We investigate the environment in which direct-collapse black holes may form by analysing a cosmological, hydrodynamical simulation that is part of the First...

PublicationThe First Billion Years project: the impact of stellar radiation on the co-evolution of Populations II and III
With the first metal enrichment by Population III (Pop III) supernovae (SNe), the formation of the first metal-enriched, Pop II stars becomes possible. In turn...
