GALEX Detection of Lyman Break Galaxies at z=1 in the CDFS
D. Burgarella, P. Perez-Gonzalez, V. Buat +5
The first large sample of Lyman Break Galaxies (LBGs) at z~1 is selected from GALEX Far-UV and Near-UV images of the Chandra Deep Field South. This multi-wavelength study is based…
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…
The Formation of Galaxies, the Formation of Old Globular Clusters and the Link with High-Redshift Objects
Denis Burgarella, Markus Kissler-Patig, Veronique Buat
In this paper, we are exploring the properties of old, metal-poor globular clusters in galaxies. We investigate whether their properties are related to the properties of their host…
Far infrared and Far ultraviolet emissions of galaxies: luminosity functions and selection effects. Implications for the future NGST and ALMA observations
V. Buat, D. Burgarella
The FIR(60 microns) and UV (0.2 microns) emissions of individual star forming galaxies are compared to the mean properties of the local Universe. Almost all the galaxies exhibit a…
The globular cluster system around the low-luminosity S0 galaxy NGC 7457
S. Chapelon, V. Buat, D. Burgarella +1
We investigate the globular cluster system around the low-luminosity S0 galaxy NGC 7457 with deep B, V, I photometry. From the V photometry the total number of globular clusters ar…
Simulated NGST Observations
D. Burgarella, R. Bouwens, T. Broadhurst +3
This paper presents the results of simulated NGST observations. The goal of this work is to study the detectability of very high redshift galaxies and to try to characterize Wide D…
