Primordial Trispectrum from Isocurvature Fluctuations
David Langlois, Tomo Takahashi
We study non-Gaussianity generated by adiabatic and isocurvature primordial perturbations. We first obtain, in a very general setting, the non-linear perturbations, up to third ord…
The ACS Fornax Cluster Survey. X. Color Gradients of Globular Cluster Systems in Early-Type Galaxies
Chengze Liu, Eric W. Peng, Andres Jordan +4
We use the largest homogeneous sample of globular clusters (GCs), drawn from the ACSVCS and ACSFCS, to investigate the color gradients of GC systems in 76 early-type galaxies. We f…
A tale of two GRB-SNe at a common redshift of z = 0.54
Z. Cano, D. Bersier, C. Guidorzi +71
We present ground-based and HST optical observations of the optical transients (OTs) of long-duration Gamma Ray Bursts (GRBs) 060729 and 090618, both at a redshift of z = 0.54. For…
The ACS Fornax Cluster Survey. IV. Deprojection of the Surface Brightness Profiles of Early-Type Galaxies in the Virgo and Fornax Clusters: Investigating the "Core/Power-Law Dichotomy"
Lisa Glass, Laura Ferrarese, Patrick Cote +8
Although early observations with the Hubble Space Telescope (HST) pointed to a sharp dichotomy among early-type galaxies in terms of the logarithmic slope gamma' of their central s…
The Detection of a Population of Submillimeter-Bright, Strongly-Lensed Galaxies
Mattia Negrello, R. Hopwood, G. De Zotti +86
Gravitational lensing is a powerful astrophysical and cosmological probe and is particularly valuable at submillimeter wavelengths for the study of the statistical and individual p…
Revisiting the Hubble sequence in the SDSS DR7 spectroscopic sample: a publicly available bayesian automated classification
Marc Huertas-Company, J. A. L Aguerri, M. Bernardi +2
We present an automated morphological classification in 4 types (E,S0,Sab,Scd) of ~700.000 galaxies from the SDSS DR7 spectroscopic sample based on support vector machines. The mai…
HerMES : SPIRE detection of high redshift massive compact galaxies in GOODS-N field
A. Cava, G. Rodighiero, I. Perez-Fournon +47
We have analysed the rest-frame far infrared (FIR) properties of a sample of massive (Mstar > 10^11Msun) galaxies at 2<z<3 in the GOODS (Great Observatories Origins Deep Survey) No…
Large-scale radio nebula around the Ultra-Luminous X-ray Source IC 342 X-1
D. Cseh, C. Lang, S. Corbel +2
We present discovery of a radio nebula associated with the ultraluminous X-ray source (ULX) IC 342 X-1 using the Very Large Array (VLA). Taking the surrounding nebula as a calorime…
External field effect of modified Newtonian dynamics in the Solar system
Luc Blanchet, Jerome Novak
The Modified Newtonian Dynamics (MOND) has been formulated as a modification of the Poisson equation for the Newtonian gravitational field. This theory generically predicts a viola…
High-resolution images of five radio quasars at early cosmological epochs
S. Frey, Z. Paragi, L. I. Gurvits +2
Context: Until now, there have only been seven quasars at z>4.5 whose the high-resolution radio structure had been studied in detail with Very Long Baseline Interferometry (VLBI) i…
Precision cosmology with a wide area XMM cluster survey
M. Pierre, F. Pacaud, J. B. Juin +3
We explore the cosmological constraints expected from wide area XMM-type cluster surveys covering 50-200 deg2, under realistic observing conditions. We perform a Fisher matrix anal…
Radio interferometric observations of two core-dominated triple radio sources at z>3
D. Cseh, S. Frey, Z. Paragi +2
Aims. We selected two radio quasars (J1036+1326 and J1353+5725) based on their 1.4-GHz radio structure, which is dominated by a bright central core and a pair of weaker and nearly…
On the squeezed limit of the bispectrum in general single field inflation
Sébastien Renaux-Petel
We investigate the consistency relation relating the squeezed limit of the bispectrum to the scalar spectral index in single field models of inflation. We give a simple integral fo…
General treatment of isocurvature perturbations and non-Gaussianities
David Langlois, Angela Lepidi
We present a general formalism that provides a systematic computation of the linear and non-linear perturbations for an arbitrary number of cosmological fluids in the early Univers…
A collisional origin for the Leo ring
Leo Michel-Dansac, Pierre-Alain Duc, Frederic Bournaud +6
Extended HI structures around galaxies are of prime importance to probe galaxy formation scenarios. The giant HI ring in the Leo group is one of the largest and most intriguing HI…
Extreme flux states of NGC 4151 observed with INTEGRAL
P. Lubinski, A. A. Zdziarski, R. Walter +5
We present a comprehensive spectral analysis of all INTEGRAL data obtained so far for the X-ray--bright Seyfert galaxy NGC 4151. We also use all contemporaneous data from RXTE, XMM…
Gravitational Waves from Abelian Gauge Fields and Cosmic Strings at Preheating
Jean-Francois Dufaux, Daniel G. Figueroa, Juan Garcia-Bellido
Primordial gravitational waves provide a very important stochastic background that could be detected soon with interferometric gravitational wave antennas or indirectly via the ind…
Constraining Fundamental Physics with Future CMB Experiments
Silvia Galli, Matteo Martinelli, Alessandro Melchiorri +3
The Planck experiment will soon provide a very accurate measurement of Cosmic Microwave Background anisotropies. This will let cosmologists determine most of the cosmological param…
A change in the optical polarization associated with a gamma-ray flare in the blazar 3C 279
LAT Collaboration, members of the 3C 279 multi-band campaign
It is widely accepted that strong and variable radiation detected over all accessible energy bands in a number of active galaxies arises from a relativistic, Doppler-boosted jet po…
