Fermi LAT Observations of the Vela Pulsar
A. A. Abdo
The Vela pulsar is the brightest persistent source in the GeV sky and thus is the traditional first target for new gamma-ray observatories. We report here on initial Fermi Large Ar…
XMM-Newton discovery of 2.6 s pulsations in the soft gamma-ray repeater SGR 1627-41

After nearly a decade of quiescence, the soft gamma-ray repeater SGR 1627-41 reactivated on 2008 May 28 with a bursting episode followed by a slowly decaying enhancement of its per…
The spatial clustering of X-ray selected AGN in the XMM-COSMOS field
R. Gilli, G. Zamorani, T. Miyaji +70
We study the spatial clustering of 538 X-ray selected AGN in the 2 deg^2 XMM-COSMOS field that are spectroscopically identified to I_{AB}<23 and span the redshift range z=0.2-3.0.…

We report the results of a 3-weeks multi-wavelength campaign on the flat spectrum radio quasar 3C 273 carried out with the AGILE gamma-ray mission, covering the 30 MeV -50 GeV and…
Exploring the spreading layer of GX 9+9 using RXTE and INTEGRAL
P. Savolainen, D. C. Hannikainen, O. Vilhu +3
We have fitted ~200 RXTE and INTEGRAL spectra of the neutron star LMXB GX 9+9 from 2002-2007 with a model consisting of a disc blackbody and another blackbody representing the spre…
On the evolution of the Gamma- and X-ray luminosities of Pulsar Wind Nebulae
Fabio Mattana, Maurizio Falanga, Diego Götz +7
Pulsar wind nebulae are a prominent class of very high energy (E > 0.1 TeV) Galactic sources. Their Gamma-ray spectra are interpreted as due to inverse Compton scattering of ultrar…
Chandra astrometry sets a tight upper limit to the proper motion of SGR 1900+14
A. De Luca, P. A. Caraveo, P. Esposito +1
The soft gamma-ray repeater (SGR) SGR 1900+14 lies a few arcminutes outside the edge of the shell supernova remnant (SNR) G42.8+0.6. A physical association between the two systems…
The zCOSMOS redshift survey: the three-dimensional classification cube and bimodality in galaxy physical properties
M. Mignoli, G. Zamorani, M. Scodeggio +56
Aims. We investigate the relationships between three main optical galaxy observables (spectral properties, colours, and morphology), exploiting the data set provided by the COSMOS/…
Multiple flaring activity in the supergiant fast X-ray transient IGR J08408-4503 observed with Swift
P. Romano, L. Sidoli, G. Cusumano +11
IGR J08408-4503 is a supergiant fast X-ray transient discovered in 2006 with a confirmed association with a O8.5Ib(f) supergiant star, HD 74194. We report on the analysis of two ou…
INTEGRAL Cross-calibration Status: Crab observations between 3 keV and 1 MeV
E. Jourdain, D. Gotz, N. J. Westergaard +2
We present results of Crab observations by the INTEGRAL instruments. A simultaneous fit allows us to demonstrate that INTEGRAL provides reliable spectra over its wide energy range.
Multiwavelength observations of 3C 454.3. I. The AGILE 2007 November campaign on the "Crazy Diamond"
S. Vercellone, A. W. Chen, V. Vittorini +68
[Abridged] We report on a multiwavelength observation of the blazar 3C 454.3 (which we dubbed "crazy diamond") carried out on November 2007 by means of the astrophysical satellites…
Thermal disc emission from a rotating black hole: X-ray polarization signatures
M. Dovciak, F. Muleri, R. W. Goosmann +2
Thermal emission from the accretion disc around a black hole can be polarized, due to Thomson scattering in a disc atmosphere. In Newtonian space, the polarization angle must be ei…
