Mkn 463 field observed by Beppo SAX
نویسنده
چکیده
In this work we present the observation of the Mkn 463 field performed with the MECS instrument on– board BeppoSAX in the 1.8–10.5 keV band. The Mkn 463 field is an example of an extragalactic field crowded with absorbed X–ray sources: apart from the Seyfert 2 galaxy Mkn 463 and the well known QSO PG 1352+183 (the only object showing no absorption), two other objects are detected with a column density in excess to the galactic value. The first 1SAX J1353.9+1820 is a red QSO from the BeppoSAX High Energy Large Area Survey (HELLAS). The second 1SAX J1355.4+1815 is optically unidentified, but its X–ray spectral characteristics indicate that it too is an AGN hidden behind a large column density.

The high spatial resolution of the MECS experiment on board Beppo-SAX has encouraged a few scientists, including the author, to perform observations of galaxy clusters. Results from the analysis of the first few observed objects are encouraging. After having reviewed the Beppo-SAX observing program for galaxy clusters and referenced contributions to these proceedings by other authors on the sam...
متن کاملThe broad band X-ray/hard X-ray spectra of accreting neutron stars
I review the energy spectra of low mass X-ray binaries (LMXBs) containing weakly magnetized accreting neutron stars (NS), emphasizing the most recent broad band (0.1-200 keV) spectral and timing observations performed by Beppo-SAX and RXTE. Drawing on the similarities between black hole candidate (BHC) and NS accretion, I discuss the accretion geometry and emission processes of NS LMXBs. INTROD...
متن کاملOn the thermal origin of the hard X-ray emission from the Coma cluster
We analyze the origin of the hard X-ray flux from the Coma cluster observed by the Beppo-SAX satellite. This flux is typically assumed to be produced by nonthermal particles accelerated in the Coma medium. We show, however, that in the case of in-situ acceleration of particles from the thermal pool, the hard X-rays in the range of Beppo-SAX observations (30−80 keV) are generated by bremsstrahlu...
متن کاملSuzaku Confirms Ngc 3660 Is an Unabsorbed Seyfert 2
An enigmatic group of objects, unabsorbed Seyfert 2s may have intrinsically weak broad line regions, obscuration in the line of sight to the BLR but not to the X-ray corona, or so much obscuration that the X-ray continuum is completely suppressed and the observed spectrum is actually scattered into the line of sight from nearby material. NGC 3660 has been shown to have weak broad optical/near i...

Ground and in flight calibrations of the MECS experiment on board Beppo-SAX have demonstrated that this is currently the best X-ray imaging experiment above 3 keV. The MECS on-axis PSF has a half power radius of about 1 arcmin. Moreover due to a fortunate combination of detector and mirror PSFs the total PSF depends only weakly on the energy. Finally the degradation of the PSF with off axis ang...
