New views on bar pattern speeds from the NUGA survey
V. Casasola, S. Garcia-Burillo, F. Combes +10
We present a review on bar pattern speeds from preliminary results in the context of the Nuclei of Galaxies (NUGA) project. The large variety of molecular circumnuclear morphologie…
Simultaneous polarization monitoring of supernovae SN2008D/XT080109 and SN2007uy: isolating geometry from dust
J. Gorosabel, A. de Ugarte Postigo, A. J. Castro-Tirado +16
The possible existence of a continuum encompassing the diversity of explosive stellar deaths,ranging from ordinary SNe to relativistic hypernovae associated with long duration GRBs…
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
S. Leon, S. Jeyakumar, D. Perez-Ramirez +3
We have mapped the \hcn emission from two spiral galaxies, NGC2903 and NGC3504 to study the gas properties in the bars. The HCN(1-0) emission is detected in the center and along th…
The AMIGA sample of isolated galaxies. VII. Far-infrared and radio continuum study of nuclear activity
J. Sabater, S. Leon, L. Verdes-Montenegro +3
We present a study of the nuclear activity in a well-defined sample of the most isolated galaxies in the local Universe traced by their far-infrared (FIR) and radio continuum emiss…
The AMIGA sample of isolated galaxies. VI. Radio continuum properties of isolated galaxies: a very radio quiet sample
S. Leon, L. Verdes-Montenegro, J. Sabater +7
The study of the radio properties of the AMIGA sample is intended to characterize the radio continuum emission for a sample least affected by local environment, thus providing a re…
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…
