The Bepposax View of Extreme Bl Lacs
We summarize the results of an observational program performed with the satellite BeppoSAX with the aim to find and study more extreme BL Lac objects. We discuss the SEDs of the observed objects and their impact on the " blazar sequence " scenario, and consider their relevance as possible TeV emitting sources.
متن کاملInteraction in Abell 2256: The BeppoSAX View.
We present results from a spatially resolved spectral analysis of the merging cluster Abell 2256. The long integration time (135 ks) and the good spatial resolution of the Medium-Energy Concentrator/Spectrometer on board BeppoSAX allow us to derive a new and substantially improved measurement of the temperature structure. We find that, within a central region of the cluster, where the effects o...
متن کاملThe BeppoSAX View of the Hot Cluster Abell 2319.
We present results from a BeppoSAX observation of the rich cluster Abell 2319. The broadband spectrum (2-50 keV) of the cluster can be adequately represented by an optically thin thermal emission model with a temperature of 9.6+/-0.3 keV and a metal abundance of 0.25+/-0.03 in solar units and with no evidence of a hard X-ray excess in the PDS spectrum. From the upper limit to the hard-tail comp...
متن کاملThe BeppoSAX view of bright Compton-thin Seyfert 2 galaxies
We present the analysis of 31 observations (17 of which are published here for the first time) of 20 bright Compton thin Seyfert 2s, in the 0.1-200 keV band, performed with the BeppoSAX satellite. The sample consists of all Seyfert 2s in the BeppoSAX public archive, with a 2-10 keV flux higher than 5×10−12 erg cm−2s−1. The good statistics available and the broad energy band permit a detailed st...
متن کاملA BeppoSAX and ROSAT view of the RCW86 supernova remnant
We present a spectral analysis of the Northern and Southwestern rim of the RCW86 X-ray shell, pointing out the remarkable differences between these two parts of the same object. In the North, a single temperature Non Equilibrium of Ionization emission model describes the data well, and the derived abundances of O, Ne, Mg, Si, S, Ar and Fe are in agreement with expected metal depletion behind a ...
