XMM-Newton and VLT observations of the isolated neutron star 1E 1207.4-5209
A. De Luca, S. Mereghetti, P. A. Caraveo +3
In August 2002, XMM-Newton devoted two full orbits to the observation of 1E 1207.4-5209, making this isolated neutron star the most deeply scrutinized galactic target of the missio…
Is there a hard tail in the Coma Cluster X-ray spectrum?
Mariachiara Rossetti, Silvano Molendi
We report results from a re-analysis of the BeppoSAX observation of Coma and from the analysis of a second, yet unpublished observation of the same object. From our re-analysis of…

Observing the high redshift universe using the VIMOS-IFU
S. Foucaud, M. Scodeggio, A. Zanichelli +2
We describe the advantages of using Integral Field Spectroscopy to observe deep fields of galaxy. The VIMOS Integral Field Unit is particularly suitable for this kind of studies th…
The 2-8 keV cosmic X-ray background spectrum as observed with XMM-Newton
Andrea De Luca, Silvano Molendi
We have measured the spectrum of the Cosmic X-ray Background (CXB) in the 2-8 keV range with the high throughput EPIC/MOS instrument onboard XMM-Newton. A large sample of high gala…
On the Iron content in rich nearby Clusters of Galaxies
Sabrina De Grandi, Stefano Ettori, Marcella Longhetti +1
In this paper we study the iron content of a sample of 22 nearby hot clusters observed with BeppoSAX. We find that the global iron mass of clusters is tightly related to the cluste…
The spectra of short Gamma-Ray Bursts
G. Ghirlanda, G. Ghisellini, A. Celotti
We present the results of the spectral analysis of a sample of short bright --ray bursts (GRB) detected by BATSE and compare them with the average and time resolved spectral pro…
GRB 030227: the first multiwavelength afterglow of an INTEGRAL GRB
A. J. Castro-Tirado, J. Gorosabel, S. Guziy +39
We present multiwavelength observations of a gamma-ray burst detected by INTEGRAL (GRB 030227) between 5.3 hours and ~1.7 days after the event. Here we report the discovery of a di…
The variable quiescence of Cen X-4
S. Campana, G. L. Israel, L. Stella +2
Cen X-4 is one of the best studied low-mass neutron star transients in quiescence. Thanks to XMM-Newton large throughput, Cen X-4 was observed at the highest signal to noise ever.…
The XMM-Newton hard band wide angle Survey
N. Carangelo, S. Molendi, the Hellas2XMM collaboration
We present the preliminary findings of our XMM-Newton Survey performed in the hard band [7-11] keV. The survey covers nearly 30 squares degrees for a total of 112 fields observed.…
GRB 021219: the first Gamma-Ray Burst localized in real time with IBAS
S. Mereghetti, D. Gotz, V. Beckmann +5
On December 19, 2002, during the Performance and Verification Phase of INTEGRAL, a Gamma-Ray Burst (GRB) has been detected and localized in real time with the INTEGRAL Burst Alert…
Integral results on GRB030320: a long gamma-ray burst detected at the edge of the field of view
A. von Kienlin, V. Beckmann, S. Covino +9
GRB030320 is the 5th Gamma-ray burst (GRB) detected by INTEGRAL in the field of view (FoV). It is so far the GRB with the largest off-axis angle with respect to the INTEGRAL pointi…
The Integral Burst Alert System (IBAS)
S. Mereghetti, D. Gotz, J. Borkowski +2
We describe the INTEGRAL Burst Alert System (IBAS): the automatic software for the rapid distribution of the coordinates of the Gamma-Ray Bursts detected by INTEGRAL. IBAS is imple…
The INTEGRAL Science Data Centre (ISDC)
T. J. -L. Courvoisier, R. Walter, V. Beckmann +17
The INTEGRAL Science Data Centre (ISDC) provides the INTEGRAL data and means to analyse them to the scientific community. The ISDC runs a gamma ray burst alert system that provides…
Unveiling the Nature of the 321 s Modulation in RX J0806.3+1527: Near-Simultaneous Chandra and VLT Observations
G. L. Israel, S. Covino, L. Stella +7
We report on the first near-simultaneous X-ray and optical observations of RX J0806.3+1527. The source is believed to be a 321s orbital period ultra-compact binary system hosting a…
Multi-object spectroscopy of low redshift EIS clusters. II
L. F. Olsen, L. Hansen, H. E. Joergensen +3
We present the results of carrying out multi-object spectroscopy in 10 EIS cluster fields. Based on the list of 345 galaxy redshifts we identify significant 3D-density enhancements…
