Low luminosity AGN represent the vast majority of the AGN population in the near universe, and still the least conforming class with the standard AGN scenario...
Embedded AGN and star formation in the central 80 pc of IC 3639
Aims: Our goal is to probe the inner structure and the nature of the mid-IR emission in the active galaxy IC 3639, which hosts a Seyfert 2 nucleus and shows...
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...
I present an overview of the types of science programs that may be feasible with EMIR. This is biased toward high-z studies and is not exhaustive. I then...
We outline two complementary applications of the tunable filter system in OSIRIS for research on external galaxies: diagnostics of the diffuse ionized gas in...
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...
Empirical calibration of the near-infrared Ca ii triplet - I. The stellar library and index definition
A new stellar library at the near-IR spectral region developed for the empirical calibration of the Caii triplet and stellar population synthesis modelling is...
Empirical calibration of the near-infrared Ca ii triplet - II. The stellar atmospheric parameters
We present a homogeneous set of stellar atmospheric parameters (Teff, logg, [Fe/H]) for a sample of about 700 field and cluster stars which constitute a new...
