Aims. We present the results from a comprehensive spectroscopic survey of the WINGS (WIde-field Nearby Galaxy-cluster Survey) clusters, a program called WINGS-SPE. The WINGS-SPE sa…
The VVDS-VLA Deep Field - IV: Radio-optical properties
S. Bardelli, E. Zucca, M. Bolzonella +51
(abridged) We use the 1.4 GHz VIMOS-VLA Deep Survey and the optical VVDS and the CFHT-LS to compare the properties of radio loud galaxies with respect to the whole population of op…
Systematic thermal reduction of neutronization in core-collapse supernovae
A. F. Fantina, P. Donati, P. M. Pizzochero
We investigate to what extent the temperature dependence of the nuclear symmetry energy can affect the neutronization of the stellar core prior to neutrino trapping during gravitat…
INTEGRAL observes the 2007 outburst of the Be transient SAX J2103.5+4545
L. Ducci, L. Sidoli, A. Paizis +2
We performed a detailed study of the 2007 outburst of the 352s pulsar SAXJ2103.5+4545, a Be/X-ray transient observed by INTEGRAL, to study its spectral and temporal properties duri…
The relationship between gas content and star formation rate in spiral galaxies. Comparing the local field with the Virgo cluster
M. Fumagalli, G. Gavazzi
Despite many studies of the star formation in spiral galaxies, a complete and coherent understanding of the physical processes that regulate the birth of stars has not yet been ach…
2MASS wide field extinction maps: II. The Ophiuchus and the Lupus cloud complexe
Marco Lombardi, Charles J. Lada, Joao Alves
We present an extinction map of a ~1,700 deg sq region that encloses the Ophiuchus, the Lupus, and the Pipe dark complexes using 42 million stars from the Two Micron All Sky Survey…
NICEST, a near-infrared color excess method tailored for small-scale structures
Marco Lombardi
Observational data and theoretical calculations show that significant small-scale substructures are present in dark molecular clouds. These inhomogeneities can provide precious hin…
The construction of non-spherical models of quasi-relaxed stellar systems
G. Bertin, A. L. Varri
Spherical models of collisionless but quasi-relaxed stellar systems have long been studied as a natural framework for the description of globular clusters. Here we consider the con…
Observation of the suppression of the flux of cosmic rays above 4x10^19eV
The Pierre Auger Collaboration
The energy spectrum of cosmic rays above 2.5x10^18eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the flux, J ~ E…
Radial metallicity profiles for a large sample of galaxy clusters observed with XMM-Newton
A. Leccardi, S. Molendi
Aims. We measured radial metallicity profiles for a sample of ~50 hot, intermediate redshift galaxy clusters, selected from the XMM-Newton archive. Methods. As in our previous pape…
TRIS I: Absolute Measurements of the Sky Brightness Temperature at 0.6, 0.82 and 2.5 GHz
M. Zannoni, A. Tartari, M. Gervasi +4
At frequencies close to 1 GHz the sky diffuse radiation is a superposition of radiation of Galactic origin, the 3 K Relic or Cosmic Microwave Background Radiation, and the signal p…
On the Fundamental Plane of the Galactic Globular Cluster System
M. Pasquato, G. Bertin
The globular clusters (GC) of our Galaxy have been found to lie close to a plane in the log(R_e), log(sigma), SB_e space, on the continuation of the Fundamental Plane (FP) known to…
A twelve-image gravitational lens system in the z ~ 0.84 cluster Cl J0152.7-1357
C. Grillo, M. Lombardi, P. Rosati +6
Gravitational lens modeling is presented for the first discovered example of a three-component source for which each component is quadruply imaged. The lens is a massive galaxy mem…
SPACE: the SPectroscopic All-sky Cosmic Explorer
A. Cimatti, M. Robberto, C. M. Baugh +18
We describe the scientific motivations, the mission concept and the instrumentation of SPACE, a class-M mission proposed for concept study at the first call of the ESA Cosmic-Visio…
The complex light-curve of the afterglow of GRB071010A
S. Covino, P. D'Avanzo, A. Klotz +51
We present and discuss the results of an extensive observational campaign devoted to GRB071010A, a long-duration gamma-ray burst detected by the Swift satellite. This event was fol…
The White Mountain Polarimeter Telescope and an Upper Limit on CMB Polarization
Alan R. Levy, Rodrigo Leonardi, Markus Ansmann +18
The White Mountain Polarimeter (WMPol) is a dedicated ground-based microwave telescope and receiver system for observing polarization of the Cosmic Microwave Background. WMPol is l…
