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…
