Star-forming regions that are visible at 3.6 μm and Hα but not in the u, g, r, i, z bands of the Sloan Digital Sky Survey are measured in five nearby spiral...
Emission-line galaxy surveys with GTC: The H α Universe
Emission line galaxies are the most easily detected and studied objects in the high redshift Universe. They are being used to trace the evolution of critical...
Emission-line maps with OSIRIS-TF: The case of M101
We investigate the suitability of GTC/OSIRIS Tunable Filters (TFs) for obtaining emission-line maps of extended objects. We developed a technique to reconstruct...
Enhanced star formation rates in AGN hosts with respect to inactive galaxies from PEP-Herschel observations
We compare the average star formation (SF) activity in X-ray selected AGN hosts with a mass-matched control sample of inactive galaxies, including both star...
Estrellas ricas en fósforo: semillas de vida en el Universo
La revista Nature Communications publica hoy el descubrimiento de un nuevo tipo de estrellas muy ricas en fósforo, que podría ayudar a explicar el origen de...
Euclid preparation - XXIII. Derivation of galaxy physical properties with deep machine learning using mock fluxes and H-band images
Next-generation telescopes, like Euclid, Rubin/LSST, and Roman, will open new windows on the Universe, allowing us to infer physical properties for tens of...
Euclid preparation. XXX. Performance assessment of the NISP red grism through spectroscopic simulations for the wide and deep surveys
This work focusses on the pilot run of a simulation campaign aimed at investigating the spectroscopic capabilities of the Euclid Near-Infrared Spectrometer and...
