The innermost region of the water megamaser radio galaxy 3C403

A. Tarchi, A. Brunthaler, C. Henkel +3

The standard unified scheme of active galactic nuclei requires the presence of high column densities of gas and dust potentially obscuring the central engine. So far, few direct su…

Star formation in isolated AMIGA galaxies: dynamical influence of bars

S. Verley, F. Combes, L. Verdes-Montenegro +2

Star formation depends strongly both on the local environment of galaxies, and on the internal dynamics of the interstellar medium. To disentangle the two effects, we obtained, in…

Discovery of Interstellar Propylene (CH_2CHCH_3): Missing Links in Interstellar Gas-Phase Chemistry

N. Marcelino, J. Cernicharo, M. Agundez +5

We report the discovery of propylene (also called propene, CH_2CHCH_3) with the IRAM 30-m radio telescope toward the dark cloud TMC-1. Propylene is the most saturated hydrocarbon e…

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…

The AMIGA sample of isolated galaxies. V. Quantification of the isolation

S. Verley, S. Leon, L. Verdes-Montenegro +8

The AMIGA project aims to build a well defined and statistically significant reference sample of isolated galaxies in order to estimate the environmental effects on the formation a…

Molecular gas in NUclei of GAlaxies (NUGA) VII. NGC4569, a large scale bar funnelling gas into the nuclear region

F. Boone, A. J. Baker, E. Schinnerer +8

This work is part of the NUGA survey of CO emission in nearby active galaxies. We present observations of NGC4569, a member of the Virgo Cluster. We analyse the molecular gas distr…

The AMIGA sample of isolated galaxies. IV. A catalogue of neighbours around isolated galaxies

S. Verley, S. C. Odewahn, L. Verdes-Montenegro +8

Studies of the effects of environment on galaxy properties and evolution require well defined control samples. Such isolated galaxy samples have up to now been small or poorly defi…

The variable radio-to-X-ray spectrum of the magnetar XTE J1810-197

F. Camilo, S. M. Ransom, J. Penalver +9

We have observed the 5.54s anomalous X-ray pulsar XTE J1810-197 at radio, millimeter, and infrared (IR) wavelengths, with the aim of learning about its broad-band spectrum. At the…

The interaction of young massive stars with their environment: A millimeter and submillimeter line study of NGC6334 FIR II

J. S. Zhang, C. Henkel, R. Mauersberger +4

Using the 15-m Swedish ESO Sub-millimeter Telescope (SEST), CO, HCN, and HCO+ observations of the galactic star-forming region NGC6334 FIR II are presented, complemented by [C I] 3…

The interstellar medium of the Antennae Galaxies

A. Schulz, C. Henkel, D. Muders +3

To study the properties of the interstellar medium in the prototypical merging system of the Antennae galaxies (NGC 4038 and NGC 4039), we have obtained CO(1-0), (2-1) and (3-2) li…

Molecular Gas in NUclei of GAlaxies (NUGA): VI. Detection of a molecular gas disk/torus via HCN in the Seyfert2 galaxy NGC6951?

M. Krips, R. Neri, S. Garcia-Burillo +8

Several studies of nearby active galaxies indicate significantly higher HCN-to-CO intensity ratios in AGN than in starburst (SB) environments. HCN enhancement can be caused by many…

Globular clusters and dwarf galaxies in Fornax - I. Kinematics in the cluster core from multi-object spectroscopy

G. Bergond, E. Athanassoula, S. Leon +6

We acquired radial velocities of a significant number of globular clusters (GCs) on wide fields between galaxies in the nearby Fornax cluster of galaxies, in order to derive their…

NUclei of GAlaxies: V. Radio emission in 7 NUGA sources

M. Krips, A. Eckart, T. P. Krichbaum +10

We present high angular resolution radio snap-shot observations of seven nearby low-luminosity active galaxies (LLAGN) from the NUclei of GAlaxies (NUGA) survey. The observations w…
