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…
HI and Hot Gas in the Outskirts of the M81 Group
M. Bureau, F. Walter, J. van Gorkom +1
Results are presented from a wide area, high resolution HI synthesis survey of the outer regions of the nearby M81 group, where internal (galactic) and external (group-related) evo…
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…
Impact of UV Radiation from Giant Spirals on the Evolution of Dwarf Galaxies
S. Mashchenko, C. Carignan, A. Bouchard
We show that ultraviolet radiation, with wavelengths shorter than 2000 A, escaping from the disks of giant spirals could be one of the principal factors affecting the evolution of…
