A Type II Supernova Hubble diagram from the CSP-I, SDSS-II, and SNLS surveys
T. de Jaeger, S. González-Gaitán, M. Hamuy +15
The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude. Such numbers will restrict spectroscopic follow-up in…
The mass profile and dynamical status of the z~0.8 galaxy cluster LCDCS 0504
L. Guennou, A. Biviano, C. Adami +34
Constraints on the mass distribution in high-redshift clusters of galaxies are not currently very strong. We aim to constrain the mass profile, M(r), and dynamical status of the $z…
Structure and substructure analysis of DAFT/FADA galaxy clusters in the [0.4-0.9] redshift range
L. Guennou, C. Adami, F. Durret +29
We analyse the structures of all the clusters in the DAFT/FADA survey for which XMM-Newton and/or a sufficient number of galaxy redshifts in the cluster range is available, with th…
Spatially-resolved dust properties of the GRB 980425 host galaxy
Michał J. Michałowski, L. K. Hunt, E. Palazzi +30
Gamma-ray bursts (GRBs) have been proposed as a tool for studying star formation in the Universe, so it is crucial to investigate whether their host galaxies and immediate environm…
A method for quantifying the Gamma Ray Burst "bias". Application in the redshift range 0-1.1
S. Boissier, R. Salvaterra, E. Le Floc'h +5
Long Gamma Ray Bursts (LGRBs) are related to the final stages of evolution of massive stars. As such, they should follow the star formation rate (SFR) of galaxies. We can use them…
Light from the Cosmic Frontier: Gamma-Ray Bursts
L. Amati, J. -L. Atteia, L. Balazs +41
Gamma-Ray Bursts (GRBs) are the most powerful cosmic explosions since the Big Bang, and thus act as signposts throughout the distant Universe. Over the last 2 decades, these ultra-…
