Soft Gamma-ray Repeaters in Clusters of Massive Stars
Felix I. Mirabel, Yael Fuchs, and Sylvain Chaty
Infrared observations of the environment of the two Soft Gamma-ray Repeaters (SGRs) with the best known locations on the sky show that they are associated to clusters of massive st…
Cosmic Statistics of Statistics
I. Szapudi, S. Colombi, F. Bernardeau
The errors on statistics measured in finite galaxy catalogs are exhaustively investigated. The theory of errors on factorial moments by Szapudi & Colombi (1996) is applied to cumul…
Smoke in the "Smoke Rings": ISO Observations of Dust in Collisional Ring Galaxies
P. N. Appleton, V. Charmandaris, C. Horellou +2
Collisional ring galaxies probably result from a head-on collision between a compact companion galaxy and a gas-rich disk system. We present a review of the discovery of warm dust…
The Robustness of Quintessence
Philippe Brax, Jerome Martin
Recent observations seem to suggest that our Universe is accelerating implying that it is dominated by a fluid whose equation of state is negative. Quintessence is a possible expla…
Sunyaev-Zel'dovich Effect Derived Distances to the High Redshift Clusters MS 0451.6-0305 and CL 0016+16
E. D. Reese, J. J. Mohr, J. E. Carlstrom +7
We determine the distances to the z~0.55 galaxy clusters MS 0451.6-0305 and CL 0016+16 from a maximum likelihood joint fit to interferometric Sunyaev-Zel'dovich effect (SZE) and X-…
XEUS - The X-ray Evolving Universe Spectroscopy Mission
A. N. Parmar, T. Peacock, M. Bavdaz +19
XEUS is under study by ESA as part of the Horizon 2000+ program to utilize the International Space Station (ISS) for astronomical applications. XEUS will be a long-term X-ray obser…
Testing Spallation Processes With Beryllium and Boron
Brian D. Fields, Keith A. Olive, Elisabeth Vangioni-Flam +1
The nucleosynthesis of Be and B by spallation processes provides unique insight into the origin of cosmic rays. Namely, different spallation schemes predict sharply different trend…
Statistical properties of the convergence due to weak gravitational lensing by non-linear structures
P. Valageas
Density fluctuations in the matter distribution lead to distortions of the images of distant galaxies through weak gravitational lensing effects. This provides an efficient probe o…
Element mixing in the Cassiopeia A supernova
T. Douvion, P. O. Lagage, C. J. Cesarsky
Thanks to mid-infrared observations, we provide new clues to the element mixing during a supernova explosion by probing the mixing between three adjacent layers: the oxygen burning…
Nucleosynthesis and Mixing in Cassiopeia A
John P. Hughes, Cara E. Rakowski, David N. Burrows +1
We present results from the first light observations of the Cassiopeia A (Cas A) supernova remnant (SNR) by the Chandra X-ray Observatory. The X-ray spectrum varies on all spatial…
Physics of the intra-cluster medium at high redshift
M. Pierre
While the concept of "clustering" primarily refers to galaxies, the fact is that galaxies can be neglected - at least in terms of mass - when considering the continuous competition…
Accretion-Ejection Instability and a "Magnetic Flood" scenario for GRS 1915+105
Michel Tagger
We present an instability, occurring in the inner region of magnetized accretion disks, which seems to be a good candidate to explain the low-frequency QPO observed in many X-ray b…
The ISOCAM/LW Detector Dark Current Behaviour
A. Biviano, M. Sauvage, P. Gallais +5
We describe the calibration, measurements and data reduction, of the dark current of the ISOCAM/LW detector. We point-out the existence of two significant drifts of the LW dark-cur…
ISO observations of the environment of the soft gamma-ray repeater SGR 1806-20
Yael Fuchs, F. Mirabel, S. Chaty +3
Observations at near and mid-infrared wavelengths (1-18 micron) of SGR 1806-20 suggest that it is associated with a cluster of giant massive stars which are enshrouded in a dense c…
The very flat radio - millimetre spectrum of Cygnus X-1
R. P. Fender, G. G. Pooley, P. Durouchoux +2
We present almost-simultaneous detections of Cygnus X-1 in the radio and mm regimes, obtained during the low/hard X-ray state. The source displays a flat spectrum between 2 and 220…
Background Light in Potential Sites for the ANTARES Undersea Neutrino Telescope
ANTARES collaboration
The ANTARES collaboration has performed a series of {\em in situ} measurements to study the background light for a planned undersea neutrino telescope. Such background can be cause…
Photons and Particle Production in Cassiopeia A: Predictions from Nonlinear Diffusive Shock Acceleration
Donald C. Ellison, Philippe Goret, Matthew G. Baring +2
We calculate particle spectra and continuum photon emission from the Cassiopeia A supernova remnant (SNR). The particle spectra, ion and electron, result from diffusive shock accel…
EROS2 microlensing search towards the Magellanic Clouds
T. Lasserre, EROS Collaboration
EROS2 is a second generation microlensing experiment operating since mid-1996 at the European Southern Observatory (ESO) at La Silla (Chile). We present the two year analysis from…
A Mid-Infrared and Far-Infrared View of Galaxies
C. J. Cesarsky, M. Sauvage
From the disk of normal galaxies to the nucleus of prototype active sources, we review the wealth of results and new understanding provided by recent infrared probes and, in partic…
The Distance to the Soft Gamma Repeater SGR 1627-41
S. Corbel, C. Chapuis, T. M. Dame +1
We report millimeter observations of the line of sight to the recently discovered Soft Gamma Repeater, SGR 1627-41, which has been tentatively associated with the supernova remnant…
X-ray Clusters and the Search for Cosmic Flows
P. D. Lynam, C. A. Collins, P. A. James +2
We are engaged in an investigation of the relationship between the properties of BCG candidates and X-ray characteristics of their host clusters for a flux-limited sample of ~250 A…
Eros variable stars: A catalog of Cepheids in the Magellanic Clouds
C. Afonso
We present a catalog containing 290 LMC and 590 SMC Cepheids which have been obtained using the two 4k 8k CCD cameras of the EROS~2 microlensing survey. The Cepheids were…
An Accretion-Ejection Instability in magnetized disks
