Status of the OTELO Project
J. Cepa, A. Bongiovanni, A. M. Perez Garcia +10
The OTELO project is the extragalactic survey currently under way using the tunable filters of the OSIRIS instrument at the GTC. OTELO is already providing the deepest emission lin…
OSIRIS/GTC: status and prospects
J. Cepa, A. Bongiovanni, A. M. Perez Garcia +6
OSIRIS is the optical Day One instrument, and so far the only Spanish instrument, currently operating at the GTC. Building and testing an instrument for a 8-10m-class telescope wit…
Spectroscopic observations of a sample of dwarf spiral galaxies. II- Abundance gradients
A. M. Hidalgo-Gamez, D. Ramirez-Fuentes, J. J. Gonzalez
The oxygen gradient of four dS galaxies has been determined using abundances for several HII regions determined with four different methods. The gradient slopes of the three non-ba…
Spectroscopic observations of a sample of dwarf spirals galaxies. I.Oxygen abundances
A. M. Hidalgo-Gamez, D. Ramirez-Fuentes, J. J. Gonzalez
The oxygen abundances for four dwarf spiral galaxies have been determined using long-slit spectroscopy. The abundances of these galaxies have not previously reported in the literat…
Activity induced by Gravitational Interaction in Galaxy Pairs
D. Dultzin, J. J. Gonzalez, Y. Krongold +6
A systematic study of the nuclear emission of a sample of 97 spirals in isolated galaxy pairs with mixed morphology (E+S) shows that: 1) AGN activity is found in 40% of the spiral…
Stellar populations of early-type galaxies in different environments II. Ages and metallicities
P. Sanchez-Blazquez, J. Gorgas, N. Cardiel +1
This is the second paper of a series devoted to study the stellar content of early-type galaxies. The goal of the series is to set constraints on the evolutionary status of these o…
