PublicationExtremely Red Galaxies at z = 5–9 with MIRI and NIRSpec: Dusty Galaxies or Obscured Active Galactic Nuclei?
We study a new population of extremely red objects (EROs) recently discovered by the James Webb Space Telescope (JWST) based on their NIRCam colors F277W ‑...

PublicationFrom Naked Spheroids to Disky Galaxies: How Do Massive Disk Galaxies Shape Their Morphology?
We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we...

PublicationGalactic archaeology for amateur astronomers: RR Lyrae stars as tracers of the Milky Way formation
Cosmological models predict that large galaxies like the Milky Way formed from the accretion of smaller stellar systems. The most spectacular of these merger...

PublicationGalaxy pairs and clusters in a lambda CDM universe: Bridging observation and simulation
I use computer simulations to examine the evolution of close galaxy pair counts and the formation of galaxy clusters. I show that the evolution of the close...

PublicationHistorical Perspectives on the Concept of Galaxy Size
A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these...

NewsImages from the Hubble Space Telescope and GRANTECAN help to show how the first galaxies were formed
One of the most interesting questions for astrophysicists for the past few decades is how and when did the first galaxies form. One of the possible answers to...
