چکیده

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. Besides SgrA*, the massive black hole at the galactic center, 41 X–ray sources have been positionally associated with already classified objects. Twenty are identified with foreground stars and five with known Low Mass X–ray Binaries. The majority of the sources in our catalogue still remains unidentified. They are hard and/or severely absorbed and probably represent a large population of X-ray binaries located in the galactic center region, accreting at low accretion rates, and still largely unknown.

Chandra Observations of the Galactic Center and Nearby Edge-on Galaxies

I review our recent Chandra surveys of the center region of the Milky Way and other nearby edge-on galaxies. Our Galactic center survey, consisting of 30 overlapping pointings, provides an unprecedented high-resolution, broadband X-ray view of a 0.8x2 square degree swath along the Galactic plane. This X-ray panorama allows a separation of the discrete source and diffuse X-ray components. Our pr...

A ROSAT PSPC X-Ray Survey of the Small Magellanic Cloud

We present the results of a systematic search for point-like and moderately extended soft (0.1-2.4 keV) X-ray sources in a raster of nine pointings covering a field of 8.95 deg and performed with the ROSAT PSPC between October 1991 and October 1993 in the direction of the Small Magellanic Cloud (SMC). We detect 248 objects which we include in the first version of our SMC catalogue of soft X-ray...

Galactic X-ray Survey

We review highlights of the results obtained from recent Galactic X-ray survey observations, in particular ASCA Galactic center and plane survey and our Chandra deep survey on the (l, b) ≈ (28. ◦5, 0. ◦0) region. Strong hard X-ray diffuse components are observed from Galactic ridge, center and bulge, and they have both thermal and non-thermal spectral components. Dozens of discrete and extended...

Observation of the Starburst Galaxy NGC 2146

We present six monitoring observations of the starburst galaxy NGC 2146 using the Chandra X-ray Observatory. We have detected 67 point sources in the 8.7×8.7 field of view of the ACIS-S detector. Six of these sources were Ultra-Luminous X-ray Sources, the brightest of which has a luminosity of 5× 10 ergs s. One of the source, with a luminosity of ∼ 1× 10 ergs s, is coincident with the dynamical...

An INTEGRAL Hard X-ray Survey of the Large Magellanic Cloud

Two observation campaigns performed in 2003 and 2004 with the INTEGRAL satellite have provided the first sensitive survey of the Large Magellanic Cloud with an imaging instrument in the hard X-ray range (15 keV 10 MeV). The high energy flux and long term variability of the black hole candidate LMC X–1 was measured for the first time without the contamination of the nearby (∼25′) young pulsar PS...
