CharlaProbing the early Universe with radio galaxies
Luminous high-redshift radio galaxies (HzRGs) are associated with the most massive known galaxies in the early Universe. These galaxies have the properties...

PublicaciónRevised Primordial Helium Abundance Based on New Atomic Data
We have derived a primordial helium abundance of Yp=0.2477+/-0.0029, based on new atomic physics computations of the recombination coefficients of He I and of...

PublicaciónSHARDS Frontier Fields: Physical Properties of a Low-mass Lyα Emitter at z = 5.75
We analyze the properties of a multiply imaged Lyα (Lyα) emitter at z = 5.75 identified through SHARDS Frontier Fields intermediate-band imaging of the Hubble...

CharlaSimulating cosmic reionization
The first galaxies are thought to have started the reionization of the Universe, that is the transformation of the cosmic hydrogen from its initial neutral to...

PublicaciónSpatial dependence of the star formation history in the central regions of the Fornax dwarf spheroidal galaxy
We present the star formation history (SFH) and the age-metallicity relation (AMR) in three fields of the Fornax dwarf spheroidal galaxy. They sample a region...

PublicaciónSpectroscopic Confirmation of CEERS NIRCam-selected Galaxies at z ≃ 8-10
We present JWST/NIRSpec prism spectroscopy of seven galaxies selected from Cosmic Evolution Early Release Science (CEERS) survey NIRCam imaging with photometric...

CharlaStar and galaxy formation, then and now
This lecture will address recent progress in modeling the emergence of cosmic structure at high redshifts. Also new insights gained from numerical simulations...

CharlaStellar black holes at the dawn of the Universe: cosmological implications
The so called "dark ages" of the universe began about 400.000 years after the Big Bang as matter cooled down and space became filled with neutral hydrogen for...
