ELMER is a multi-purpose Camera&Spectrograph in the optical range for the GTC. ELMERs electro-mechanical design was based in well known, straightforward and...
Elmer Mechanics: Manufacturing, Integration and Testing
ELMER is a visible imager-spectrograph currently scheduled to be in operation at the GTC on Day One. The design phase of the ELMER Structure and Mechanisms...
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...
