The Molecular Hydrogen Explorer H2EX
F. Boulanger, J. P. Maillard, P. Appleton +12
The Molecular Hydrogen Explorer, H2EX, was proposed in response to the ESA 2015 - 2025 Cosmic Vision Call as a medium class space mission with NASA and CSA participations. The miss…
Lyman alpha emitting galaxies at 0.2 < z < 0.35 from GALEX spectroscopy
Jean-Michel Deharveng, Todd Small, Tom A. Barlow +19
The GALEX (Galaxy Evolution Explorer) spectroscopic survey mode, with a resolution of about 8 A in the FUV (1350 - 1750 A) and about 20 A in the NUV (1950 - 2750 A) is used for a s…
GALEX UV Color Relations for Nearby Early-Type Galaxies
Jose Donas, Jean-Michel Deharveng, R. Michael Rich +23
We use GALEX/optical photometry to construct color-color relationships for early-type galaxies sorted by morphological type. We have matched objects in the GALEX GR1 public release…
VLT narrow-band photometry in the Lyman continuum of two galaxies at z~3: Limits to the escape of ionizing flux
A. K. INOUE, I. Iwata, J. -M. Deharveng +2
We have performed narrow-band imaging observations with the Very Large Telescope, aimed at detecting the Lyman continuum (LC) flux escaping from galaxies at z~3. We do not find any…
The Look-back Time Evolution of Far-UV Flux from Elliptical Galaxies: The Fornax Cluster and Abell 2670
Y. -W. Lee, C. H. Ree, R. M. Rich +30
In order to investigate the origin of the far-UV (FUV) flux from the early-type galaxies, Galaxy Evolution Explorer (GALEX) is collecting the UV data for the elliptical-rich cluste…
Classical and MgII-selected Damped Lyman-alpha Absorbers: impact on Omega_HI at z<1.7
Celine Peroux, Jean-Michel Deharveng, Vincent Le Brun +1
The Damped Lyman-alpha systems (DLAs), seen in absorption in the spectrum of quasars, are believed to contain a large fraction of the neutral gas in the Universe. Paradoxically, th…
