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…
Halpha Kinematics of Tidal Tails in Interacting Systems: Projection Effects and Dark Matter in TDGs
P. Amram, F. Bournaud, P. -A. Duc
Several interacting systems exhibit at the tip of their long tidal tails massive condensations of atomic hydrogen, which may be the progenitors of Tidal Dwarf Galaxies. Because, qu…
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…
Multiwavelength Rotation Curves to Test Dark Halo Central Shapes
Sebastien Blais-Ouellette, Claude Carignan, Philippe Amram
We use Fabry-Perot Halpha spectroscopy, complemented with published HI radio synthesis observations to derive high resolution rotation curves of spiral galaxies. We investigate pre…
