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…
ce-61: a Tidal Dwarf Galaxy in the Hercules cluster?
W. van Driel, P. -A. Duc, P. Amram +9
A candidate Tidal Dwarf Galaxy, ce-61, was identified in the merger system IC 1182 in the Hercules supercluster. The multi-wavelength data we obtained so far do not prove, however,…
A 3D Optical Spectroscopy Study of Low Surface Brightness Galaxies
L. Chemin, P. Amram, C. Carignan +6
We present Halpha emission line velocity fields of two Low Surface Brightness galaxies - UGC 628 and UGC 5005 - obtained using Fabry-Perot interferometry observations at the Canada…
Environmental Effects on the Kinematics of Virgo Cluster Galaxies
L. Chemin, V. Cayatte, C. Balkowski +9
We present results from an ongoing survey dedicated to the ionized gas kinematics of Virgo cluster spiral galaxies using Fabry-Perot interferometry. Our goal is to study the enviro…
HI deficiency in the galaxy cluster ACO 3627. ATCA observations in the Great Attractor region
B. Vollmer, V. Cayatte, W. van Driel +5
ATCA 21 cm HI observations of the rich galaxy cluster ACO 3627 in the Great Attractor region are presented. Three fields of 30' diameter located within one Abell radius of ACO 3627…
The consequences of ram pressure stripping on the Virgo cluster spiral galaxy NGC 4522
B. Vollmer, M. Marcelin, P. Amram +3
New H-alpha Fabry-Perot interferometer observations of the Virgo cluster spiral galaxy NGC 4522 are presented. A velocity field up to a radius of 60'' was obtained. The observed ro…
