The X-ray Source at the Center of the Cassiopeia A Supernova Remnant
S. Mereghetti, A. Tiengo, G. L. Israel
We present the first results of an XMM-Newton observation of the central X-ray source in the Cas A supernova remnant. The spectrum can be fit equally well with an absorbed steep po…
Observations of Anomalous X-ray Pulsars
G. L. Israel, S. Mereghetti, L. Stella
We review recent results obtained from observations of Anomalous X-ray Pulsars at different wavelengths (X-rays, Optical, IR and Radio) with particular emphasis on results obtained…
XMM-EPIC observation of MCG-6-30-15: Direct evidence for the extraction of energy from aspinning black hole?
Joern Wilms, Christopher S. Reynolds, Mitchell C. Begelman +4
We present XMM-Newton European Photon Imaging Camera (EPIC) observations of the bright Seyfert 1 galaxy MCG-6-30-15, focusing on the broad Fe K line at ~6keV and the associated…
On the Nature of the EIS Candidate Clusters: Confirmation of z<0.6 candidates
L. F. Olsen, C. Benoist, L. da Costa +7
We use public V-band imaging data from the wide-angle surveys conducted by the ESO Imaging Survey project (EIS) to further investigate the nature of the EIS galaxy cluster candidat…
Re-examining the X-Ray versus Spin-Down Luminosity Correlation of Rotation Powered Pulsars
Andrea Possenti, Rossella Cerutti, Monica Colpi +1
The empirical relation between the X-ray luminosity (in the 2-10 keV band) and the rate of spin-down energy loss of a sample of 37 pulsars is re-examined considering recent data fr…
The HELLAS2XMM survey: I. The X-ray data and the Log(N)-Log(S)
A. Baldi, S. Molendi, A. Comastri +3
We present the first results from an XMM-Newton serendipitous medium-deep survey, which covers nearly three square degrees. We detect a total of 1022, 495 and 100 sources, down to…
The pulse phase-dependent spectrum of the anomalous X-ray pulsar 1RXS J170849-400910
G. L. Israel, T. Oosterbroek, L. Stella +3
We report on the results of a 50ks BeppoSAX observation of 1RXS J170849-400910, one of the five (plus a candidate) known anomalous X-ray pulsars. The BeppoSAX data are consistent w…
The X-ray emission of the Intermediate Polar V709 Cas
D. de Martino, G. Matt, K. Mukai +6
We present RXTE and BeppoSAX observations of the Intermediate Polar V709 Cas acquired in 1997 and 1998 respectively. The X-ray emission from 0.1 to 30keV is dominated by the strong…
The distance to the Vela pulsar gauged with HST parallax oservations
P. A. Caraveo, A. De Luca, R. P. Mignani +1
The distance to the Vela pulsar (PSR B0833-45) has been traditionally assumed to be 500 pc. Although affected by a significant uncertainty, this value stuck to both the pulsar and…
Multicolor Photometry of the Vela Pulsar
R. P. Mignani, P. A. Caraveo
Multicolor photometry of the Vela pulsar (PSR B0833-45), updated by recent HST/WFPC2 observations obtained in the 555W, 675W and 814W filters, is presented. The available data prov…
On the metal abundance in the core of M87
Silvano Molendi, Fabio Gastaldello
We revisit the XMM-Newton observation of M87 to make a new and more detailed measurement of the metal abundance profile. After having verified that spectral fits with single temper…
Is the gas in cooling-flows multi-phase?
Silvano Molendi, Fabio Pizzolato
Employing XMM-Newton EPIC data we perform a detailed comparison between different spectral models to test whether the gas in cooling-flows is multi-phase or not. Our findings all p…
Discovery of circular polarization in the Intermediate Polar 1WGA J1958.2+3232
M. Uslenghi, L. Tommasi, A. Treves +2
We report on UBVRI polarimetry of the recently identified Intermediate Polar 1WGA J1958.2+3232, carried out on 2000 August, 4-6 at the Nordic Optical Telescope. Circular polarizati…
1.65 micron (H-band) surface photometry of galaxies. VII: dwarf galaxies in the Virgo cluster
G. Gavazzi, S. Zibetti, A. Boselli +3
We present near-infrared H-band (1.65micron) observations and surface brightness profile decompositions for 75 faint (13.5 < m_p < 18.5) galaxies, primarily taken among dwarf Ellip…
X-ray emission from the giant molecular clouds in the Galactic Center region and the discovery of new X-ray sources
L. Sidoli, S. Mereghetti, A. Treves +3
We report the results of X-ray (2-10 keV) observations of the giant molecular clouds SgrB, SgrC and SgrD in the Galactic Center region, together with the discovery of the point-lik…
A catalogue of soft X-ray sources in the galactic center region
L. Sidoli, T. Belloni, S. Mereghetti
We present a catalogue of 107 point-like X-ray sources derived from a systematic analysis of all the ROSAT PSPC observations of the galactic center region performed in 1992-1993. B…
SuperAGILE: the X-ray Monitor of the AGILE gamma-ray Mission
M. Feroci, E. Costa, E. Del Monte +15
SuperAGILE is the X-ray stage of the AGILE gamma-ray mission. It is devoted to monitor X-ray (10-40 keV) sources with a sensitivity better than 10 mCrabs in 50 ks and to detect X-r…
