Optical and infrared flares from a transient Galactic soft gamma-ray repeater
A. J. Castro-Tirado, A. de Ugarte Postigo, J. Gorosabel +33
Soft gamma-ray repeaters (SGRs) are a rare type of gamma-ray transient sources that are ocasionally detected as bursts in the high-energy sky. They are thought to be produced by ma…
HCN(1-0) enhancement in the bar of NGC 2903

Molecular gas in nearby elliptical radio galaxies
B. Ocana-Flaquer, S. Leon, J. Lim +2
Powerful radio-AGN are hosted by massive elliptical galaxies which are usually very poor in molecular gas. Nevertheless the central Black Hole (BH) needs molecular gas for the nucl…
Dynamical Influence of Bars on the Star Formation in Isolated Galaxies
S. Verley, F. Combes, L. Verdes-Montenegro +2
Star formation depends strongly on both the local environment of galaxies and the internal dynamics of the interstellar medium. To disentangle the two effects, we obtained, in the…
The NUGA project: The Seyfert 2 galaxy NGC3147
V. Casasola, F. Combes, S. Garcia-Burillo +3
We present CO(1-0) and CO(2-1) maps of the Seyfert 2 galaxy NGC3147 of the NUclei of GAlaxies (NUGA) sample at 1.8'' x 1.6'' and 1.4'' x 1.2'' resolution respectively. Identifying…
Nuclear starburst-driven evolution of the central region in NGC 6764
S. Leon, A. Eckart, S. Laine +6
We study the CO and the radiocontinuum emission in an active galaxy to analyze the interplay between the central activity and the molecular gas. We present new high-resolution obse…
Fueling the central engine of radio galaxies. I. The molecular/dusty disk of 4C 31.04
S. Garcia-Burillo, F. Combes, R. Neri +4
We report the detection of a massive (M(gas) > 5x10^9 Msun) molecular/dusty disk of 1.4kpc-size fueling the central engine of the Compact Symmetric Object (CSO) 4C31.04 based on hi…
The AMIGA sample of isolated galaxies III. IRAS data and infrared diagnostics
U. Lisenfeld, L. Verdes-Montenegro, J. Sulentic +6
We describe the mid- (MIR) and far- (FIR) infrared properties of a large (1000) sample of the most isolated galaxies in the local Universe. This sample is intended as a ``nur…
AMIGA: Very low environment galaxies in the local Universe
S. Verley, F. Combes, L. Verdes-Montenegro +8
The evolutionary history of galaxies is thought to be strongly conditioned by the environment. In order to quantify and set limits on the role of nurture one must identify and stud…
