Classification and Characterization of Objects from GALEX and SDSS surveys
Luciana Bianchi, M. Seibert, W. Zheng +22
We use the GALEX (Galaxy Evolution Explorer) Medium Imaging Survey (MIS) and All-Sky Imaging Survey (AIS) data available in the first internal release, matched to the SDSS catalogs…
The UV (GALEX) and FIR (ASTRO-F) All Sky Surveys: the measure of the dust extinction in the local universe
V. Buat, T. T. Takeuchi, A. Boselli +9
Before the end of 2002 will be launched the GALEX satellite (a NASA/SMEX project) which will observe all the sky in Ultraviolet (UV) through filters at 1500 and 2300 A down to m(AB…
Mid-IR and Far-UV observations of the star-forming ring of M 31
L. Pagani, J. Lequeux, D. Cesarsky +4
We present mid-IR images of a 15'x15' field in the south-west part of the Andromeda galaxy M 31 obtained with the ISOCAM camera on board ISO. We also present a 20" resolution far-U…
Discovery of a z=0.808 damped Lyman-alpha system candidate in a UV selected quasar spectrum
V. Le Brun, M. Viton, B. Milliard
We present the observation of a new intermediate redshift damped Lyman-alpha absorption system candidate, discovered in the course of a spectroscopic follow-up for identifying the…
The Lyman continuum radiation escaping from galaxies
J. -M. Deharveng, S. Faisse, B. Milliard +1
The H-alpha luminosity density of galaxies is used to calculate the local diffuse radiation field at the Lyman limit as resulting from star formation in the universe. The fraction…
