On the polar caps of the 3 Musketeers
A. De Luca, P. A. Caraveo, S. Mereghetti +2
XMM-Newton observations of PSR B0656+14, PSR B1055-52 and Geminga have substantially increased the statistics available for these three isolated neutron stars, so apparently simila…
XMM-Newton observation of 4U 1543-475: the X-ray spectrum of a stellar-mass black-hole at low luminosity

INTEGRAL and XMM-Newton Observations of GRB040106
L. Moran, S. Mereghetti, D. Gotz +10
On January 6th 2004, the IBAS burst alert system triggered the 8th gamma-ray burst (GRB) to be located by the INTEGRAL satellite. The position was determined and publicly distribut…
The GALEX-VVDS Measurement of the Evolution of the 1500A Luminosity Function
S. Arnouts, D. Schiminovich, O. Ilbert +8
We present the first measurement of the galaxy luminosity function at 1500A between 0.2<z<1.2 based on GALEX-VVDS observations (1000 spectroscopic redshifts for galaxies with NUV<2…
INTEGRAL discovery of persistent hard X-ray emission from the Soft Gamma Ray Repeater SGR 1806-20

We report the discovery of persistent hard X-ray emission extending up to 150 keV from the soft gamma-ray repeater SGR 1806-20 using data obtained with the INTEGRAL satellite in 20…
Feasibility study of a Laue lens for hard X-rays for space astronomy
A. Pisa, F. Frontera, P. De Chiara +8
We report on the feasibility study of a Laue lens for hard X-rays (>60 keV)based on mosaic crystals, for astrophysical applications. In particular we discuss the scientific motivat…
INTEGRAL observations of the PSR B1259-63 / SS2883 system after the 2004 periastron passage
S. E. Shaw, M. Chernyakova, J. Rodriguez +3
The millisecond pulsar PSR B1259-63 and the Be star SS2883 are situated in a highly eccentric binary system, with orbital period ~3.4 years. We report on hard X-ray observations ob…
The broad-band X-ray spectrum of the dipping Low Mass X-ray Binary EXO0748--676
Lara Sidoli, Arvind N. Parmar, Tim Oosterbroek
We present results of a 0.1-100 keV BeppoSAX observation of the dipping LMXRB EXO 0748-676 performed in 2000 November. During the observation the source exhibited X-ray eclipses, t…
Phase-resolved spectroscopy of Geminga shows rotating hot spot(s)
P. A. Caraveo, A. De Luca, S. Mereghetti +2
Isolated neutron stars are seen in x-rays through their nonthermal and/or surface thermal emissions. XMM-Newton observations of the Geminga pulsar show a 43 electron volt spectrum…
A first XMM-Newton look at the relativistic double pulsar PSR J0737-3039
A. Pellizzoni, A. De Luca, S. Mereghetti +5
We present the results of a 50 ks long X-ray observation of the relativistic double pulsar system PSR J0737-3039 obtained with the XMM-Newton satellite in March 2004. The source ha…
Prompt and afterglow X-ray emission from the X-Ray Flash of 2002 April 27
L. Amati, F. Frontera, J. J. M. in 't Zand +15
We report on the X-ray observations of the X-ray flash (XRF) which occurred on 2002 April 27, three days before BeppoSAX was switched off. The event was detected with the BeppoSAX…
ATLAS and SYNTHE under Linux
L. Sbordone, P. Bonifacio, F. Castelli +1
We have successfully ported under GNU Linux ATLAS 9, the widely used stellar atmosphere modeling code, as well as both the SYNTHE suite of programs, its ``companion'' for spectral…
Data Reduction and Analysis Graphical Organizer
L. Paioro, B. M. Garilli, M. Scodeggio +1
Spectroscopic surveys are undergoing a rapid expansion in their data collecting capabilities, reaching the level of hundreds of spectra per pointing. An efficient use of such huge…
