GHASP : An Halpha kinematic survey of spiral and irregular galaxies - VI. New Halpha data cubes for 108 galaxies
B. Epinat, P. Amram, M. Marcelin +7
We present the Fabry-Perot observations obtained for a new set of 108 galaxies that completes the GHASP survey (Gassendi HAlpha survey of SPirals). The GHASP survey consists of 3D…
Kinematics and Stellar Populations of Low-Luminosity Early-Type Galaxies in the Abell 496 Cluster
Igor Chilingarian, Veronique Cayatte, Florence Durret +5
The morphology and stellar populations of low-luminosity early-type galaxies in clusters have until now been limited to a few relatively nearby clusters such as Virgo or Fornax. Sc…
IMAGES-III: The evolution of the Near-Infrared Tully-Fisher relation over the last 6 Gyr
M. Puech, H. Flores, F. Hammer +22
Using the multi-integral field spectrograph GIRAFFE at VLT, we have derived the K-band Tully-Fisher relation (TFR) at z~0.6 for a representative sample of 65 galaxies with emission…
GALEX observations of Low Surface Brightness Galaxies: UV color and star formation efficiency
S. Boissier, A. Gil de Paz, A. Boselli +7
We present GALEX UV observations of a sample of Low Surface Brightness (LSB) galaxies for which HI data are available, allowing us to estimate their star formation efficiency. We f…
H-alpha Kinematics of the SINGS Nearby Galaxies Survey. II
I. Dicaire, C. Carignan, P. Amram +8
This is the second part of an H-alpha kinematics follow-up survey of the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample. The aim of this program is to shed new light on the…
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…
