The asymmetric compact jet of GRS 1915+105
M. Ribo, V. Dhawan, I. F. Mirabel
We present multiepoch VLBA observations of the compact jet of GRS 1915+105 conducted at 15.0 and 8.4 GHz during a {\it plateau} state of the source in 2003 March-April. These obser…
Constraining the local radiation field and the grain size distribution in dust SED modelling of dwarf galaxies
F. Galliano
I present a simple self-consistent dust spectral energy distribution (SED) model that has been applied to fit the well-sampled observed UV-to-radio SED of four nearby starbursting…
Investigating the EGRET-radio galaxies link with INTEGRAL: the case of 3EG J1621+8203 and NGC 6251
L. Foschini, M. Chiaberge, P. Grandi +10
The analysis of an INTEGRAL AO2 observation of the error contours of the EGRET source 3EG J1621+8203 is presented. The only source found inside the error contours for energies betw…
Unusual X-ray transients in the Galactic Centre
Masaaki Sakano, Robert S. Warwick, Anne Decourchelle +1
We report the discovery in the Galactic Centre region of two hard X-ray sources, designated as XMM J174457-2850.3 and XMM J174544-2913.0, which exhibited flux variations in the 2--…
Transmission of light in deep sea water at the site of the Antares neutrino telescope
ANTARES collaboration
The ANTARES neutrino telescope is a large photomultiplier array designed to detect neutrino-induced upward-going muons by their Cherenkov radiation. Understanding the absorption an…
Sensitivity of the EDELWEISS WIMP search to spin-dependent interactions
A. Benoit, L. Berge, J. Bluemer +35
The EDELWEISS collaboration is searching for WIMP dark matter using natural Ge cryogenic detectors. The whole data set of the first phase of the experiment contains a fiducial expo…
3-200 keV spectral states and variability of the INTEGRAL Black Hole binary IGR J17464-3213
F. Capitanio, P. Ubertini, A. Bazzano +12
On March 2003, IBIS, the gamma-ray imager on board the INTEGRAL satellite, detected an outburst from a new source, IGR J17464-3213, that turned out to be a HEAO-1 transient, H1743-…
Molecular dynamics simulation of gaseous atomic hydrogen interactions with hydrocarbon grains
Renaud Papoular
Semi-empirical molecular dynamics is used to simulate several gaseous atomic hydrogen interactions with hydrocarbon grains in space: recoil, adsorption, diffusion, chemisorption an…
Star-forming protoclusters associated with methanol masers
V. Minier, M. G. Burton, T. Hill +5
We present a multiwavelength study of five methanol maser sites which are not directly associated with a strong ( mJy) radio continuum source: G 31.28+0.06, G 59.78+0.06, G 1…
GRBs and the 511 keV emission of the Galactic bulge
E. Parizot, M. Cassé, R. Lehoucq +1
We consider the phenomenology of the 511 keV emission in the Galactic bulge, as recently observed by INTEGRAL, and propose a model is which the positrons are produced by gamma-ray…
H.E.S.S. Observations of PKS 2155-304
The H. E. S. S. Collaboration, :, F. Aharonian
The high-frequency peaked BL Lac PKS 2155-304 at redshift z=0.117 has been detected with high significance (~45 sigma) at energies greater than 160 GeV, using the H.E.S.S. stereosc…
A general catalogue of 6.7 GHz methanol masers. I: data
M. Pestalozzi, V. Minier, R. Booth
Methanol masers are often detected in regions of intense star formation. Several studies in the last decade indicate that they may even be the earliest signpost of a high-mass star…
High-energy particle acceleration in the shell of a supernova remnant
H. E. S. S. Collaboration, :, F. Aharonian
A significant fraction of the energy density of the interstellar medium is in the form of high-energy charged particles (cosmic rays). The origin of these particles remains uncerta…
SPI observations of positron annihilation radiation from the 4th galactic quadrant: Spectroscopy
V. Lonjou, G. Weidenspointner, J. Knodlseder +13
The status of the analysis of the electron/positron annihilation radiation performed by INTEGRAL/SPI in the 4th GALACTIC QUADRANT is reported. We use data from the first two Galact…
Evidence for radio-source heating of groups
J. H. Croston, M. J. Hardcastle, M. Birkinshaw
We report evidence that the gas properties of X-ray groups containing radio galaxies differ from those of radio-quiet groups. For a well-studied sample of ROSAT-observed groups, we…
The ISGRI CdTe gamma camera In-flight behavior
Francois Lebrun
The INTEGRAL Soft Gamma-Ray Imager (ISGRI) is the first large CdTe gamma camera ever built. It provided faultless operations in space since the launch of INTEGRAL in October 2002.…
The ECLAIRs micro-satellite for multi-wavelength studies of gamma-ray burst prompt emission
S. Schanne, J. -L. Atteia, D. Barret +15
The cosmological revolution of 1997 has established that (at least long duration) gamma-ray bursts (GRB) are among the most energetic events in the Universe and occur at cosmologic…
Did most present-day spirals form during the last 8 Gyrs? A formation history with violent episodes revealed by panchromatic observations
F. Hammer, H. Flores, D. Elbaz +3
(abridged) Studies of distant galaxies have shown that ellipticals and large spirals were already in place 8 Gyr ago, leading to a very modest recent star formation in intermediate…
