IRIS: A new generation of IRAS maps
Marc-Antoine Miville-Deschenes, Guilaine Lagache
The Infrared Astronomical Satellite (IRAS) had a tremendous impact on many areas of modern astrophysics. In particular it revealed the ubiquity of infrared cirrus that are a specta…
Radiodetection of Cosmic Ray Extensive Air Showers
D. Ardouin, A. Belletoile, D. Charrier +12
We present the characteristics and performance of a demonstration experiment devoted to the observation of ultra high- energy cosmic ray extensive air showers using a radiodetectio…
Photodisintegration of Ultra-High-Energy Cosmic Rays revisited
E. Khan, S. Goriely, D. Allard +5
Recent microscopic and phenomenological calculations of giant dipole resonances for A <= 56 nuclei are presented. The derived photodisintegration cross sections are exhaustively co…
Evidence of intense hot(~340K) dust in 3CR radio galaxies The most dissipative source of cooling in AGNs
B. Rocca-Volmerange, M. Remazeilles
The spectra of the powerful 3CR radio galaxies present a typical distribution in the far-infrared. From the observed radio to X-ray spectral energy distribution (SED) templates, we…
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…
Clusters of Galaxies: New Results from the CLEF Hydrodynamics Simulation
S. T. Kay, A. C. da Silva, N. Aghanim +5
Preliminary results are presented from the CLEF hydrodynamics simulation, a large (N=2(428)^3 particles within a 200 Mpc/h comoving box) simulation of the LCDM cosmology that inclu…
Evolution of the infrared luminosity density and star formation history up to z~1: preliminary results from MIPS
E. Le Floc'h, C. Papovich, H. Dole +6
Using deep observations of the Chandra Deep Field South obtained with MIPS at 24mic, we present our preliminary estimates on the evolution of the infrared (IR) luminosity density o…
Fe XXV and Fe XXVI lines from low velocity, photoionised gas in the X-ray spectra of AGN
Stefano Bianchi, Giorgio Matt, Fabrizio Nicastro +2
We have calculated the equivalent widths of the absorption lines produced by Fe XXV and Fe XXVI in a Compton-thin, low-velocity photoionised material illuminated by the nuclear con…
Influence of the definition of dissipative events on their statistics
Eric Buchlin, Sebastien Galtier, Marco Velli
A convenient and widely used way to study the turbulent plasma in the solar corona is to do statistics of properties of events (or structures), associated with flares, that can be…
Atomic carbon in PSS 2322+1944, a quasar at redshift 4.12
J. Pety, A. Beelen, P. Cox +4
We report the detection of the 3P1 to 3P0 fine-structure line of neutral carbon in the z=4.12 quasar PSS 2322+1944, obtained at the IRAM Plateau de Bure interferometer. The CI 3P1-…
A method of generating initial conditions for cosmological N body simulations
M. Joyce, D. Levesque, B. Marcos
We investigate the possibility of generating initial conditions for cosmological N-body simulations by simulating a system whose correlations at thermal equilibrium approximate wel…
The European Large Area ISO Survey VIII: 90-micron final analysis and source counts
Ph. Heraudeau, S. Oliver, C. del Burgo +17
We present a re--analysis of the European Large Area ISO Survey (ELAIS) 90mum observations carried out with ISOPHOT, an instrument on board the ESA's Infrared Space Observatory (IS…
Resolved Molecular Gas in a Quasar Host Galaxy at Redshift z=6.42
F. Walter, C. Carilli, F. Bertoldi +5
We present high-resolution VLA observations of the molecular gas in the host galaxy of the highest redshift quasar currently known, SDSS J1148+5251 (z=6.42). Our VLA data of the CO…
Variation of the constants in the late and early universe
Jean-Philippe Uzan
Recent key observational results on the variation of fine structure constant, the proton to electron mass ratio and the gravitational constant are reviewed. The necessity to substa…
Beam mismatch effects in Cosmic Microwave Background polarization measurements
Cyrille Rosset, Vladimir Yurchenko, Jacques Delabrouille +4
Measurement of cosmic microwave background polarization is today a major goal of observational cosmology. The level of the signal to measure, however, makes it very sensitive to va…
Primordial quadrupole-induced polarisation from filamentary structures and galaxy clusters
Guo Chin Liu, Antonio da Silva, Nabila Aghanim
We present the first computation of the Cosmic Microwave Background (CMB) polarisation power spectrum from galaxy clusters and filaments using hydrodynamical simulations of large s…
GZK horizon and magnetic fields
Etienne Parizot
We discuss some aspects of the propagation of high-energy cosmic rays (CRs) in turbulent magnetic fields, and propose a formula for the diffusion coefficient based on accurate simu…
Evolutionary synthesis of galaxies at high spectral resolution with the code PEGASE-HR
Damien Le Borgne, Brigitte Rocca-Volmerange, Philippe Prugniel +3
We present PEGASE-HR, a new stellar population synthesis program generating high resolution spectra (R=10 000) over the optical range lambda=400--680 nm. It links the spectro-photo…
