Initial Results from the High Energy Experiment PDS aboard BeppoSAX

چکیده
The high energy experiment PDS is one of the Narrow Field Instruments aboard the X–ray astronomy satellite BeppoSAX . It covers the energy band from 15 to 300 keV. Here we report results on its in-flight performance and observations of galactic and extragalactic X–ray sources obtained during the Science Verification Phase of the satellite: in particular Crab, Cen X–3, 4U1626–67 and PKS2155–305.

Bepposax/pds Observation of Vela X–1
Vela X–1 has been observed by the Italian/Dutch X–ray satellite BeppoSAX during its Science Verification Phase. During the ∼ 50 ksec observation (orbital phases 0.27–0.34) two different intensity state are present, situation very common in this source. We report results from the pulse phase averaged and pulse phase resolved spectroscopy from the high-energy instrument PDS aboard BeppoSAX.
متن کاملSix Years of Gamma Ray Burst Observations with BeppoSAX
I give a summary of the prompt X–/gamma–ray detections of Gamma Ray Bursts (GRBs) with the BeppoSAX satellite and discuss some significant results obtained from the study of the prompt emission of these GRBs obtained with the BeppoSAX Gamma Ray Burst Monitor and Wide Field Cameras. 1. The BeppoSAX revolution All the efforts performed before BeppoSAX, an Italian satellite with Dutch participatio...
متن کاملThe Last Gift of Bepposax: Pds Observations of the Two Blazars 1es 0507-040 and Pks 1229-021
Towards the end of the BeppoSAX mission, the only operated Narrow Field Instrument was the PDS, which covers the energy range 13-300 keV. Two blazars, 1ES 0507-040 (z = 0.304) and PKS 1229-021 (z = 1.045), suitably located in the sky for BeppoSAX pointing, were observed for about 2 days each in Spring 2002 with the PDS and detected up to 50 keV. 1ES0507-040 had been already observed by the Bepp...
متن کاملBepposax/pds Serendipitous Detections at High Galactic Latitudes
At a flux limit of∼10 erg cm s in the 20–100 keV band, the PDS instrument on–board BeppoSAX offers the opportunity to study the extragalactic sky with an unprecedented sensitivity. In this work we report on the results of a search in the BeppoSAX archive for serendipitous high energy sources at high galactic latitudes (|b| ≥ 13◦). We have defined a set of twelve regions in which the PDS/MECS cr...
متن کاملBeppoSAX Spectral Survey of BL Lacs - new spectra and results
We present BeppoSAX LECS, MECS, and PDS spectra of eleven X-ray selected BL Lacertae objects. Combining these sources with the ones presented elsewhere we have a sample of 21 BL Lacs from the Einstein Medium Sensitivity and Einstein Slew Survey. The sample shows strong correlations of several physical parameters with the peak frequency of the synchrotron branch of the spectral energy distributi...
