We present the initial results of a 3-mm spectral line survey towards 83 methanol maser selected massive star-forming regions. Here we report observations of the J=5-4 and 6-5 rota…
INTEGRAL observation of the high-mass X-ray transient V0332+53 during the 2005 outburst decline
N. Mowlavi, I. Kreykenbohm, S. E. Shaw +7
The decline of the high mass X-ray transient V0332+53 during the Dec. 2004 to Feb. 2005 outburst is analysed from the data recorded by INTEGRAL. The flux is shown to decrease expon…
The Galactic black hole transient H1743-322 during outburst decay: connections between timing noise, state transitions and radio emission
E. Kalemci, J. A. Tomsick, R. E. Rothschild +3
Multi-wavelength observations of Galactic black hole transients during outburst decay are instrumental for our understanding of the accretion geometry and the formation of outflows…
Do measurements of the one-point distribution of aperture-mass improve constraints on cosmology ?
Dipak Munshi, Patrick Valageas
We study the possibility of using the entire probability distribution function (PDF) of the aperture mass Map and its related cumulative probability distribution function (CPDF) to…
26Al in the inner Galaxy
R. Diehl, H. Halloin, K. Kretschmer +12
We performed a spectroscopic study of the 1809 keV gamma-ray line from 26Al decay in the Galaxy using the SPI imaging spectrometer with its high-resolution Ge detector camera on th…
Evolution of the X-Ray Jets from 4U 1755--33
P. Kaaret, S. Corbel, J. A. Tomsick +4
We report on new X-ray observations of the large-scale jets recently discovered in X-rays from the black hole candidate 4U 1755-33. Our observations in 2004 show that the jets foun…
SS 433 : a phenomenon imitating a Wolf-Rayet star
Yael Fuchs, L. Koch Miramond, P. Abraham
We present mid-infrared (2-12 micron) spectra of the microquasar SS 433 obtained with the Infrared Space Observatory (spectroscopic mode of ISOPHOT and ISOCAM). We compare them to…
Two-phase X-ray burst from GX 3+1 observed by INTEGRAL
Jerome Chenevez, Maurizio Falanga, Soeren Brandt +6
INTEGRAL detected on August 31, 2004, an unusual thermonuclear X-ray burst from the low-mass X-ray binary GX 3+1. Its duration was 30 min, which is between the normal burst duratio…
Critical revision of the ZEPLIN-I sensitivity to WIMP interactions
A. Benoit, M. Chapellier, G. Chardin +10
The ZEPLIN collaboration has recently published its first result presenting a maximum sensitivity of picobarn for a WIMP mass of 60 GeV. The analysis…
INTEGRAL/IBIS Extragalactic survey: 20-100 keV selected AGN
L. Bassani, M. Molina, A. Malizia +10
Analysis of INTEGRAL Core Program and public Open Time observations performed up to April 2005 provides a sample of 62 active galactic nuclei in the 20-100 keV band above a flux li…
Bimodal spectral variability of Cygnus X-1 in an intermediate state
J. Malzac, P. O. Petrucci, E. Jourdain +11
We report the results of an observation of Cygnus X-1 with INTEGRAL, that we combine with simultaneous radio observations with the Ryle telescope. Both spectral and variability pro…
The weak INTEGRAL bursts GRB040223 and GRB040624: an emerging population of dark afterglows
P. Filliatre, S. Covino, P. D'Avanzo +18
We report here gamma-ray, X-ray and near-infrared observations of GRB040223 along with gamma-ray and optical observations of GRB040624. GRB040223 was detected by INTEGRAL close to…
Reviving Dead Zones in Accretion Disks by Rossby Vortices at their Boundaries
P. varniere, M. Tagger
Models of the accretion disks of Young Stellar Objects show that they should not be ionized at a few AU from the star, and thus not subject to the MHD turbulence believed to cause…
FRII sources at z>0.5: X-ray properties of the core and extended emission
E. Belsole, J. H. Croston, D. M. Worrall +1
Active galaxies are the most powerful engines in the Universe for converting gravitational energy into radiation, and their study at all epochs of evolution is therefore important.…
