Spiral arms, as those of our own Milky Way, are some of the most spectacular features in disc galaxies. It has been argued that star formation should proceed...
Dust in the Reionization Era: ALMA Observations of a z = 8.38 Gravitationally Lensed Galaxy
We report on the detailed analysis of a gravitationally lensed Y-band dropout, A2744_YD4, selected from deep Hubble Space Telescope imaging in the Frontier...
Dust-obscured star formation in the outskirts of XMMU J2235.3-2557, a massive galaxy cluster at z = 1.4
Star formation (SF) in the galaxy populations of local massive clusters is reduced with respect to field galaxies, and tends to be suppressed in the core region...
Dynamical simulations of the interacting galaxies in the NGC 520/UGC 957 system
Numerical simulations of the interacting galaxies in the NGC 520/UGC 957 system are presented. Two sets of models were produced to investigate the postulated...
Electron densities in HII regions across galaxy discs
When we measure the electron density within an H II region using ratios of emission lines we find characteristic values in the range of 100-300 cm -3. But when...
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...
