Large-Scale Structure of the Universe and Cosmological Perturbation Theory
F. Bernardeau, S. Colombi, E. Gaztanaga +1
We review the formalism and applications of non-linear perturbation theory (PT) to understanding the large-scale structure of the Universe. We first discuss the dynamics of gravita…
A Closer Look at the Soft X-ray Transient X1608-52: Long-term Optical/X-ray Observations
S. Wachter, D. W. Hoard, C. D. Bailyn +2
We report long-term simultaneous optical and (RXTE) X-ray observations of the soft X-ray transient and low mass X-ray binary X1608-52 spanning from 1999 to 2001. In addition to the…
Modelling Plerion Spectra and their Evolution
Yves A. Gallant, Eric van der Swaluw, John G. Kirk +1
We review recent theoretical developments on pulsar winds, their nebulae and relativistic shock acceleration, and show how they illuminate unsolved problems in plerion spectra, in…
A 2.4-80 micron spectrophotometric study of SS433 with ISO
Yael Fuchs, Lydie Koch-Miramond, Peter Abraham
We present ISOPHOT spectrophotometric observations of SS433 at four different orbital phases in 1996 and 1997. The HeI+HeII lines in both spectra of SS433 and the Wolf-Rayet star W…
Near Infrared Observations of Galactic Black Hole Candidates
S. Chaty, I. F. Mirabel, P. Goldoni +4
We report on several European Southern Observatory (ESO) near-infrared (NIR) observational campaigns aimed at understanding the nature of galactic black hole candidates. Our result…
Interacting Dark Matter disguised as Warm Dark Matter
Celine Boehm, Alain Riazuelo, Steen H. Hansen +1
We explore some of the consequences of Dark Matter-photon interactions on structure formation, focusing on the evolution of cosmological perturbations and performing both an analyt…
Mass loss from galaxies: feeding the IGM, recycling in the IGM
Pierre-Alain Duc, Jonathan Braine, Ute Lisenfeld +2
As a result of internal processes or environmental effects like ram-pressure stripping or collisions, galaxies lose a significant part of their stellar and gaseous content. Whereas…
SIGMA Observations of the Bursting Pulsar GRO J1744-28
J. Mejia, T. Villela, P. Goldoni +13
We present the results of the GRANAT/SIGMA hard X-/soft gamma-ray long-term monitoring of the Galactic Center (GC) region concerning the source GRO J1744-28, discovered on 1995 Dec…
ISO investigates the nature of extremely-red hard X-ray sources responsible for the X-ray background
Alberto Franceschini, Dario Fadda, Catherine Cesarsky +3
We analyse very deep X-ray and mid-IR surveys in common areas of the Lockman Hole and the HDF North to study the sources of the X-ray background (XRB) and to test the standard obsc…
The AGN contribution to mid-infrared surveys
Dario Fadda, Hector Flores, Guenther Hasinger +5
We provide constraints on the AGN contribution to the mid-IR extragalactic background light from a correlation analysis of deep X-ray and mid-IR observations in two regions centred…
Cosmological Hydrodynamics with Adaptive Mesh Refinement: a new high resolution code called RAMSES
Romain Teyssier
A new N-body and hydrodynamical code, called RAMSES, is presented. It has been designed to study structure formation in the universe with high spatial resolution. The code is based…
X-rays from Star-Forming Regions in the VLT Era
Thierry Montmerle, Nicolas Grosso
The association between star-forming regions and X-ray emission was discovered over 30 years ago. We now know that essentially all young stellar objects, T Tauri stars and protosta…
ISOCAM Mid-InfraRed Detection of HR 10: A Distant Clone of Arp 220 at z=1.44
David Elbaz, Hector Flores, Pierre Chanial +5
We report the detection of the extremely red object (ERO), HR 10 (I-K= 6.5, z=1.44), at 4.9 and 6.1 microns (rest-frame) with ISOCAM, the mid-infrared (MIR) camera onboard the Infr…
Lithium Depletion in Pre-Mainsequence Solar-Like Stars
L. Piau, S. Turck-Chieze
We examine the internal structure of solar-like stars in detail between 0.8 and 1.4M Sun and during pre-main sequence phase. Recent opacity computations of OPAL along with a new hy…
The Galactic Halo from Microlensing
A. Milsztajn
The status of the microlensing search for galactic dark matter in the form of massive astronomical compact halo objects (machos) is reviewed. Unresolved issues are discussed, as we…
XMM-Newton Observation of a Distant X-ray Selected Cluster of Galaxies at z=1.26 with Possible Cluster Interaction
Yasuhiro Hashimoto, Guenther Hasinger, Monique Arnaud +2
We report on the XMM-Newton (XMM) observation of RXJ1053.7+5735, one of the most distant (z = 1.26) X-ray selected clusters of galaxies, which also shows an unusual double-lobed X-…
X-ray Evidence for Spectroscopic Diversity of Type Ia Supernovae: XMM observation of the elemental abundance pattern in M87
A. Finoguenov, K. Matsushita, H. Boehringer +2
We present the results of a detailed element abundance study of hot gas in M87, observed by XMM-Newton. We choose two radial bins, 1'-3' and 8'-16' (8'-14' for EMOS; hereafter the…
On Rossby waves and vortices with differential rotation
Michel Tagger
We present a simplified model for linearized perturbations in a fluid with both differential rotation and differential vorticity. Without the latter the model reduces to the classi…
A powerful local shear instability in stratified disks
D. Richard, F. Hersant, O. Dauchot +3
In this paper, we show that astrophysical accretion disks are dynamically unstable to non-axisymmetric disturbances. This instability is present in any stably stratified anticyclon…
The X-ray surface brightness profiles of hot galaxy clusters up to z~0.8: evidence for self-similarity and constraints on Omega_0
M. Arnaud, N. Aghanim, D. M. Neumann
We study the ROSAT surface brightness profiles of a sample of 25 distant (0.3<z<0.83) hot (kT>3.5keV) clusters. For both open and flat cosmological models, the derived emission mea…
