A Multifrequency approach of the cosmological parameter estimation in presence of extragalactic point sources
D. Paoletti, N. Aghanim, M. Douspis +4
We present a multifrequency approach which optimizes the constraints on cosmological parameters with respect to extragalactic sources and secondary anisotropies contamination on sm…
GALEX selected Lyman Break Galaxies at z~2: Comparison with other Populations
L. Haberzettl, G. M. Williger, M. D. Lehnert +2
We present results of a search for bright Lyman break galaxies at 1.5<=z<=2.5 in the GOODS-S field using a NUV-dropout technique in combination with color-selection. We derived a s…
Constraints on the CMB temperature redshift dependence from SZ and distance measurements
A. Avgoustidis, G. Luzzi, C. J. A. P. Martins +1
The relation between redshift and the CMB temperature, is a key prediction of standard cosmology, but is violated in many non-standard models. Constraining po…

We present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-…
Spitzer mid-IR spectroscopy of powerful 2Jy and 3CRR radio galaxies. I. Evidence against a strong starburst-AGN connection in radio-loud AGN
D. Dicken, C. Tadhunter, D. Axon +9
We present deep Spitzer/IRS spectra for complete samples of 46 2Jy radio galaxies (0.05<z<0.7) and 19 3CRR FRII radio galaxies (z<0.1), and use the detection of polycyclic aromatic…
The WIRCam Deep Survey I: Counts, colours and mass-functions derived from near-infrared imaging in the CFHTLS deep fields
R. Bielby, P. Hudelot, H. J. McCracken +10
We present a new near-infrared imaging survey in the four CFHTLS deep fields: the WIRCam Deep Survey (WIRDS). WIRDS comprises extremely deep, high quality (FWHM ~0.6") J, H and K i…
Gauge-invariant perturbations at second order in two-field inflation
Eleftheria Tzavara, Bartjan van Tent
We study the second-order gauge-invariant adiabatic and isocurvature perturbations in terms of the scalar fields present during inflation, along with the related fully non-linear s…
A semi-empirical library of galaxy spectra for Gaia classification based on SDSS data and PEGASE models
P. Tsalmantza, A. Karampelas, M. Kontizas +6
Aims:This paper is the third in a series implementing a classification system for Gaia observations of unresolved galaxies. The system makes use of template galaxy spectra in order…
Dense gas without star formation: The kpc-sized molecular disk in 3C326 N
Nicole Nesvadba, Francois Boulanger, Matt Lehnert +2
We report the discovery of a 3 kpc disk of few 10^9 Ms of dense, warm H_2 in the nearby radio galaxy 3C326 N, which shows no signs of on-going or recent star formation and falls a…
From large scale gas compression to cluster formation in the Antennae overlap region
Cinthya N. Herrera, François Boulanger, Nicole P. H. Nesvadba
We present a detailed observational analysis of how merger-driven turbulence may regulate the star-formation efficiency during galaxy interactions and set the initial conditions fo…
Modeling the evolution of infrared galaxies : clustering of galaxies in the Cosmic Infrared Background
Aurélie Pénin, Olivier Doré, Guilaine Lagache +1
Star-forming galaxies are a highly biased tracer of the underlying dark matter density field. Their clustering can be studied through the cosmic infrared background anisotropies. T…
Introducing the Dirac-Milne universe
Aurélien Benoit-Lévy, Gabriel Chardin
The ΛCDM standard model, although an excellent parametrization of the present cosmological data, requires two as yet unobserved components, Dark Matter and Dark Energy, for more th…
Gravitational entropy of black holes and wormholes
Gustavo E. Romero, Romain Thomas, Daniela Pérez
Pure thermodynamical considerations to describe the entropic evolution of the universe seem to violate the Second Law of Thermodynamics. This suggests that the gravitational field…
Directional limits on persistent gravitational waves using LIGO S5 science data
J. Abadie, B. P. Abbott, R. Abbott +712
The gravitational-wave (GW) sky may include nearby pointlike sources as well as astrophysical and cosmological stochastic backgrounds. Since the relative strength and angular distr…
The Average Optical Spectra of Intense Starbursts at z~2: Outflows and the Pressurization of the ISM
L. Le Tiran, M. D. Lehnert, W. van Driel +2
An important property of star-forming galaxies at z~1-2 is the high local star-formation intensities they maintain over tens of kiloparsecs at levels that are only observed in the…
Photometric selection of Type Ia supernovae in the Supernova Legacy Survey
G. Bazin, V. Ruhlmann-Kleider, N. Palanque-Delabrouille +23
We present a sample of 485 photometrically identified Type Ia supernova candidates mined from the first three years of data of the CFHT SuperNova Legacy Survey (SNLS). The images w…
