The MW is an exceptionnally quiet galaxy: implications for spiral formation
M. Puech, F. Hammer, L. Chemin +2
We compare both the Milky Way and M31 to local external disk galaxies within the same mass range, using their relative locations in the planes formed by Vflat vs. MK (the Tully-Fis…
Dark matter in low mass surface density galaxies
Laurent Chemin, Claude Carignan, Philippe Amram
Low mass surface density spiral and irregular galaxies like low surface brightness (LSB) and dwarf galaxies are unique laboratories to study the dynamical properties of Dark Matter…
Discovery of a new M32-like "Compact Elliptical" galaxy in the halo of the Abell 496 cD galaxy
Igor Chilingarian, Veronique Cayatte, Laurent Chemin +4
Aims: ``Compact ellipticals'' are so rare that a search for M32 analogs is needed to ensure the very existence of this class. Methods: We report here the discovery of A496cE, a M32…
Extended HI Rotation Curve of M31 using deep DRAO observations
Claude Carignan, Laurent Chemin, Tyler Foster
Carignan et al. (2006) recently presented an extended HI rotation curve (RC) of M31, using single dish observations from the 100m Effelsberg and Green Bank telescopes. These observ…
Structure and evolution of star-forming gas in late-type spiral galaxies
Kambiz Fathi, John E. Beckman, Almudena Zurita +7
We study two dimensional Fabry-Perot interferometric observations of the nearby face-on late-type spiral galaxy, NGC 628. We investigate the role of the individual HII regions toge…
