Infrared and X-Ray Evidence for Circumstellar Grain Destruction by the Blast Wave of Supernova 1987A
E. Dwek, R. G. Arendt, P. Bouchet +10
Multiwavelength observations of supernova remnant (SNR) 1987A show that its morphology and luminosity are rapidly changing at X-ray, optical, infrared, and radio wavelengths as the…
A2163: Merger events in the hottest Abell galaxy cluster I. Dynamical analysis from optical data
S. Maurogordato, A. Cappi, C. Ferrari +7
We present a detailed optical analysis of the galaxy cluster A2163 based on new multicolor wide field imaging and medium-to-high resolution (R~2000) spectroscopy. While X-ray obser…
Time drift of cosmological redshifts and its variance
Jean-Philippe Uzan, Francis Bernardeau, Yannick Mellier
The contribution of cosmological perturbations to the time drift of the cosmological redshift is derived. It is shown that the dominant correction arises from the local acceleratio…

B. Mosser, F. Bouchy, M. Martic
This paper reports a 9-night asteroseismic observation program conducted in January 2007 with the new spectrometer Sophie at the OHP 193-cm telescope, on the F5 IV-V target Procyon…
Modelling the spectral energy distribution of ULIRGs II: The energetic environment and the dense interstellar medium
O. Vega, M. S. Clemens, A. Bressan +4
We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst…
HESS VHE Gamma-Ray Sources Without Identified Counterparts
HESS Collaboration, F. Aharonian
The detection of gamma rays in the very-high-energy (VHE) energy range (100 GeV--100 TeV) provides a direct view of the parent population of ultra-relativistic particles found in a…
The nature of the ghost cavity in the NGC 741 group
Nazirah N. Jetha, Martin J. Hardcastle, Arif Babul +4
We discuss the effects of energy injection into the intra-group medium of the group of galaxies associated with NGC 741. The X-ray emission reveals a large bubble, which in the abs…
SZ and CMB reconstruction using Generalized Morphological Component Analysis
J. Bobin, Y. Moudden, J. -L. Starck +2
In the last decade, the study of cosmic microwave background (CMB) data has become one of the most powerful tools to study and understand the Universe. More precisely, measuring th…
Two years of INTEGRAL monitoring of GRS 1915+105 Part 1: multiwavelength coverage with INTEGRAL, RXTE, and the Ryle radio Telescope
J. Rodriguez, D. C. Hannikainen, S. E. Shaw +13
(Abridged) We report the results of monitoring observations of the Galactic microquasar GRS 1915+105 performed simultaneously with INTEGRAL and RXTE Ryle . We present the results o…
Two Years of INTEGRAL monitoring of GRS 1915+105 Part 2: X-Ray Spectro-Temporal Analysis
J. Rodriguez, S. E. Shaw, D. C. Hannikainen +14
(abridged) This is the second paper presenting the results of two years of monitoring of GRS 1915+105 with \integral and \rxte and the Ryle Telescope. We present the X-ray spectral…
The XMM-LSS cluster sample and its cosmological applications. Prospects for the XMM next decade
M. Pierre, F. Pacaud, J. B. Melin +1
The well defined selection function of the XMM-LSS survey enables a simultaneous modelling of the observed cluster number counts and of the evolution of the L-T relation. We presen…
UV/Optical Detections of Candidate Tidal Disruption Events by GALEX and CFHTLS
S. Gezari, S. Basa, D. C. Martin +11
We present two luminous UV/optical flares from the nuclei of apparently inactive early-type galaxies at z=0.37 and 0.33 that have the radiative properties of a flare from the tidal…
Vigorous star formation with low efficiency in massive disk galaxies at z=1.5
E. Daddi, H. Dannerbauer, D. Elbaz +4
We present the first detection of molecular gas cooling CO emission lines from ordinary massive galaxies at z=1.5. Two sources were observed with the IRAM Plateau de Bure Interfero…
Search for a Dark Matter annihilation signal from the Sagittarius dwarf galaxy with H.E.S.S
H. E. S. S. Collaboration, :, E. Moulin +5
Dwarf Spheroidal galaxies are amongst the best targets to search for a Dark Matter annihilation signal. The annihilation of WIMPs in the center of Sagittarius dwarf spheroidal (Sgr…

HESS Collaboration, F. Aharonian
AIMS: Very high energy (VHE; E>100 GeV) gamma-ray studies were performed for 18 active galactic nuclei (AGN) from a variety of AGN classes. METHODS: VHE observations of a sample of…
Mid-Infrared Spectral Diagnosis of Submillimeter Galaxies

Building Giant-Planet Cores at a Planet Trap
Alessandro Morbidelli, Aurelien Crida, Frederic Masset +1
A well-known bottleneck for the core-accretion model of giant-planet formation is the loss of the cores into the star by Type-I migration, due to the tidal interactions with the ga…
