We report Atacama Large Millimeter Array (ALMA) observations of four high-redshift dusty star-forming galaxy candidates selected from far-infrared (FIR)...
PublicationDiscovery of Four Apparently Cold Dusty Galaxies at z = 3.62─5.85 in the COSMOS Field: Direct Evidence of Cosmic Microwave Background Impact on High-redshift Galaxy Observables
PublicationExtended Point-spread Functions for Deep Astronomical Imaging Surveys
The low surface brightness (LSB) universe is one of the last frontiers in observational astronomy. However, uncovering the information contained in ultra-deep...
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...
Technical facilityLaPalma supercomputer
LaPalma supercomputer is one of twelve nodes located on Spanish territory linked together to form the Spanish Supercomputing Network.
PublicationLocal and Global Gas Metallicity versus Stellar Age Relation in MaNGA Galaxies
The search for new global scaling relations linking the physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially...

PublicationThe Galaxy "Missing Dark Matter" NGC 1052-DF4 is Undergoing Tidal Disruption
The existence of long-lived galaxies lacking dark matter represents a challenge to our understanding of how galaxies form. Here, we present evidence that...
