TL;DR
This study provides a comprehensive analysis of the broad-band X-ray spectral properties of a complete sample of 36 Type 1 AGN detected by INTEGRAL, revealing average spectral parameters and their implications for AGN models.
Contribution
It offers the first complete broad-band spectral analysis of a well-defined INTEGRAL-selected Type 1 AGN sample, including average properties and parameter distributions.
Findings
Average photon index of 1.7 with 0.2 dispersion
Mean high-energy cut-off around 100 keV, mostly 50-150 keV
Average reflection fraction of 1.5 with 0.7 dispersion
Abstract
In this paper we discuss the broad-band X-ray characteristics of a complete sample of 36 type 1 AGN, detected by INTEGRAL in the 20-40 keV band above the 5.5sigma level. We present, for all the objects in the sample, the broad-band (1-110 keV) spectral analysis obtained by using INTEGRAL/Swift-BAT observations together with XMM-Newton, Chandra, ASCA and Swift/XRT data. We also present the general average properties of the sample, i.e. the distribution of photon indices, high energy cut-offs, reflection fractions and absorption properties, together with an in-depth analysis of their parameter space. We find that the average Seyfert 1 power law has an index of 1.7 with a dispersion of 0.2. The mean cut-off energy is at around 100 keV, with most objects displaying Ec in the range 50-150 keV; the average amount of Compton reflection is 1.5 with a typical dispersion of 0.7. We do not find…
