X-ray spectrum (0.1-10 keV) of the broad line radio galaxy - 3C 390.3

Abstract

Broad line radio galaxy, 3C 390.3, was observed with EXOSAT on several occassions between 1984 and 1986 using the low (LE) and medium (ME) energy detectors. Detailed results of the spectral analysis of the LE (0.1-2 keV) and ME (2-10 keV) spectra which were obtained from the EXOSAT archives, of this source are presented. Simple power law and uniform absorption model provided good fit to the combined LE and ME spectra but the hydrogen column density (N H ) values are much smaller than the galactic N H value. However, the above model with the fixed N H value also provides good fit to the datasets.
