Spectroscopic follow-up of FIRBACK-South-Marano bright galaxies
J. Patris, M. Dennefeld, G. Lagache +1
We present optical spectroscopy of the brightest 170 microns sources in the FIRBACK South Marano (FSM) field. The survey is 90% complete at the 4 sigma level. The spectra are compa…
CIV Absorbers in z>4 Quasars: Tracing Early Galactic Halos Evolution
Celine Peroux, Patrick Petitjean, Bastien Aracil +2
We use 29 z>4 quasar spectra to build a homogeneous sample of high-redshift CIV absorbers. We use these data to calculate the number density, n(z), of W_rest(CIV)>0.30 A CIV double…
FUSE observations of G226-29: First detection of the H_2 quasi-molecular satellite at 1150A
N. F. Allard, G. Hébrard, J. Dupuis +4
We present new FUV observations of the pulsating DA white dwarf G226-29 obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE). This ZZ Ceti star is the brightest one of i…
Inflation and Precision Cosmology
Jerome Martin
A brief review of inflation is presented. After having demonstrated the generality of the inflationary mechanism, the emphasize is put on its simplest realization, namely the singl…
On the "Causality Argument" in Bouncing Cosmologies
Jerome Martin, Patrick Peter
We exhibit a situation in which cosmological perturbations of astrophysical relevance propagating through a bounce are affected in a scale-dependent way. Involving only the evoluti…
The VIRMOS deep imaging survey: III. ESO/WFI deep U-band imaging of the 0226-04 deep field
M. Radovich, M. Arnaboldi, V. Ripepi +14
In this paper we describe the U-band imaging of the F02 deep field, one of the fields in the VIRMOS Deep Imaging Survey. The observations were done at the ESO/MPG 2.2m telescope at…
Excess mid-IR emission in Cataclysmic Variables
G. Dubus, R. Campbell, B. Kern +2
We present a search for excess mid-IR emission due to circumbinary material in the orbital plane of cataclysmic variables (CVs). Our motivation stems from the fact that the strong…
Ultra-High Energy Cosmic Rays from Quasar Remnants
C. Isola, G. Sigl, G. Bertone
One of the models recently proposed to explain the origin of the ultra high energy cosmic rays assumes that these particles may be accelerated by the electromotive force around pre…
ISO observations of four active galaxies
Michel Dennefeld, Thomas Boller, Dimitra Rigopoulou +1
We present ISO PHOT-S spectra of four galaxies known or suspected to host a central AGN, selected from the initial Iras/Rosat sample of Boller et al. (1992). Two of them had no obv…
Can Supersymmetry Naturally Explain the Positron Excess?
Dan Hooper, James E. Taylor, Joseph Silk
It has often been suggested that the cosmic positron excess observed by the HEAT experiment could be the consequence of supersymmetric dark matter annihilating in the galactic halo…
A Post-Newtonian diagnostic of quasi-equilibrium binary configurations of compact objects
Thierry Mora, Clifford M. Will
Using equations of motion accurate to the third post-Newtonian (3PN) order (O(v/c)^6 beyond Newtonian gravity), we derive expressions for the total energy E and angular momentum J…
First upper limits from LIGO on gravitational wave bursts
LIGO Scientific Collaboration, B. Abbott
We report on a search for gravitational wave bursts using data from the first science run of the LIGO detectors. Our search focuses on bursts with durations ranging from 4 ms to 10…
Star formation history and dust attenuation in galaxies drawn from ultraviolet surveys
X. Kong, S. Charlot, J. Brinchmann +1
We compile a new sample of 115 nearby, non-Seyfert galaxies spanning a wide range of star formation activities, from starburst to nearly dormant, based on ultraviolet (UV) observat…
The Chandra Deep Field South: Optical Spectroscopy I
G. P. Szokoly, J. Bergeron, G. Hasinger +15
We present the results of our spectroscopic follow-up program of the X-ray sources detected in the 942 ks exposure of the Chandra Deep Field South (CDFS). 288 possible counterparts…
Well-proportioned universes suppress CMB quadrupole
Jeffrey Weeks, Jean-Pierre Luminet, Alain Riazuelo +1
A widespread myth asserts that all small universe models suppress the CMB quadrupole. In actual fact, some models suppress the quadrupole while others elevate it, according to whet…
The runaway instability of thick discs around black holes. II. Non constant angular momentum discs
Frederic Daigne, Jose A. Font
We present results from a comprehensive number of relativistic, time-dependent, axisymmetric simulations of the runaway instability of non-constant angular momentum thick discs aro…
Long slit spectroscopy of a sample of isolated spirals with and without an AGN
I. Marquez, F. Durret, J. Masegosa +6
We present the kinematical data obtained for a sample of active (Seyfert) and non active isolated spiral galaxies, based on long slit spectra along several position angles in the H…
Early results from the VIMOS VLT Deep Survey
O. Le Fèvre, G. Vettolani, D. Maccagni +40
The VIMOS VLT Deep Survey (VVDS) is underway to study the evolution of galaxies, large scale structures and AGNs, from the measurement of more than 100000 spectra of faint objects.…
Multigravity from a discrete extra dimension
C. Deffayet, J. Mourad
Multigravity theories are constructed from the discretization of the extra dimension of five dimensional gravity. Using an ADM decomposition, the discretization is performed while…
The radio galaxy K-z relation: the 10^12 Msol mass limit; masses of galaxies from the L_K luminosity, up to z >4
B. Rocca-Volmerange, D. Le Borgne, C. De Breuck +2
The narrow K-z relation of powerful radio galaxies in the Hubble K diagram is often attributed to the stellar populations of massive elliptical galaxies. Extended over a large rang…
High order correlation functions for self interacting scalar field in de Sitter space
Francis Bernardeau, Tristan Brunier, Jean-Philippe Uzan
We present the expressions of the three- and four-point correlation functions of a self interacting light scalar field in a de Sitter spacetime at tree order respectively for a cub…
Finite volume effects for non-Gaussian multi-field inflationary models
Francis Bernardeau, Jean-Philippe Uzan
Models of multi-field inflation exhibiting primordial non-Gaussianity have recently been introduced. This is the case in particular if the fluctuations of a light field scalar fiel…
Cosmic microwave background anisotropies in multi-connected flat spaces
Alain Riazuelo, Jeffrey Weeks, Jean-Philippe Uzan +2
This article investigates the signature of the seventeen multi-connected flat spaces in cosmic microwave background (CMB) maps. For each such space it recalls a fundamental domain…
