A "UV+IR" history of star formation at 0<z<1
E. Le Floc'h, the MIPS team
The combination of both contributions from the observed UV emission and the absorbed radiations reprocessed in the infrared represents the ideal approach to constrain the activity…
Studying Distant Infrared-Luminous Galaxies with Spitzer and Hubble
Casey Papovich, Eiichi Egami, Emeric Le Floc'h +5
New surveys with the Spitzer space telescope identify distant star-forming and active galaxies by their strong emission at far-infrared wavelengths, which provides strong constrain…
24 micron Properties of X-ray Selected AGN
J. R. Rigby, G. H. Rieke, R. Maiolino +13
We examine the 24 micron to X-ray color of 157 X-ray--selected AGN as a function of X-ray obscuration and optical classification in the Chandra Deep Field South. The sample consist…
Deriving the redshift of distant galaxies with Gamma-Ray Burst transient edges
E. Le Floc'h, P. -A. Duc, I. F. Mirabel
Cosmological Gamma-Ray Bursts (GRBs) offer a unique perspective to probe the evolution of distant galaxies. We discuss one of the multiple benefits of this approach, i.e. the detec…
Gamma-Ray Bursts as a Cosmic Window for Galaxy Evolution
I. F. Mirabel, D. B. Sanders, E. Le Floc'h
Present knowledge indicates that gamma-ray bursts are linked with massive stars. They will become invaluable probes of the early universe and galaxy formation. In the future, it wi…
Searching for AGN signatures in Mid-IR Spectra: The case of NGC1068
O. Laurent, I. F. Mirabel, V. Charmandaris +3
We present mid-IR observations of the prototypical Seyfert 2 galaxy NGC 1068 obtained with ISOCAM between 5 and 16micron. The proximity of this galaxy coupled with the spectro-imag…
