X-ray Properties of Two Complementary Samples of Intermediate Seyfert Galaxies

We present the X-ray spectral analysis of two complementary sets of intermediate Seyfert galaxies (ISs).

Description
Summary:We present the X-ray spectral analysis of two complementary sets of intermediate Seyfert galaxies (ISs). Analyzing X-ray data, we estimate the hydrogen abundance NH and test its connection with the [O III] luminosity acquired from optical observations. The results confirm the conclusions drawn in a previous study concerning the lack of a direct correlation between the obscuration measure (NH) and the intrinsic characteristics of the active nuclei ([O III] luminosity). Instead, we validate the existence of a correlation between the Seyfert type and the NH parameter, employing a separation threshold of approximately 1022 atoms cm−2. Simultaneously, our findings align with prior research, corroborating the relationship between X-ray luminosity and the [O III] luminosity.
