A method for determining radio continuum spectra, and its application to large surveys
B. Vollmer, E. Davoust, P. Dubois +3
A new tool to extract cross-identifications and radio continuum spectra from radio catalogues contained in the VIZIER database of the CDS is presented. The code can handle radio su…
Torus models for obscuration in type 2 AGN
Thomas Beckert, Wolfgang J. Duschl, Bernd Vollmer
We discuss a clumpy model of obscuring dusty tori around AGN. Cloud-cloud collisions lead to an effective viscosity and a geometrically thick accretion disk, which has the required…
A Virgo high-resolution Halpha kinematical survey
L. Chemin, C. Balkowski, V. Cayatte +9
We have completed a survey of 30 Virgo cluster galaxies in the Halpha emission-line using Fabry-Perot interferometry. The goal of the survey is to obtain a high angular resolution…
Spiral Galaxy - ICM Interactions in the Virgo Cluster
Jeffrey D. P. Kenney, Hugh Crowl, Jacqueline van Gorkom +1
We discuss HI and optical evidence for ongoing ICM-ISM interactions in 6 HI-deficient Virgo cluster spiral galaxies. One of the clearest cases is the highly inclined Virgo galaxy N…
Radio continuum observations of the Virgo cluster spiral NGC 4522 The signature of ram pressure
B. Vollmer, R. Beck, J. D. P. Kenney +1
Radio continuum observations at 20 and 6 cm of the highly inclined Virgo spiral galaxy NGC 4522 are presented. Both, 20 and 6 cm total emission distributions are asymmetric with an…
NGC 4569: recent evidence for a past ram pressure stripping event
B. Vollmer, C. Balkowski, V. Cayatte +2
Deep 21-cm HI line observations of the Virgo cluster spiral galaxy NGC 4569 have been obtained with the VLA in its D configuration and with the Effelsberg 100-m telescope. A low su…
