Eleven X-ray sources detected by the SRG observatory in a specific sky region have been studied, revealing seven Seyfert 1 and four Seyfert 2 galaxies with varying absorption features. Optical and X-ray spectral analyses helped classify these active galactic nuclei and highlighted the need for deeper observations for some sources.

Why it matters: Identifying and characterizing new and poorly understood X-ray sources advances knowledge of active galactic nuclei (AGN) diversity.

The big picture: Combining ART-XC and eROSITA data with optical spectra refines AGN classifications and helps study their intrinsic absorption properties.

Stunning stat: Two of four Seyfert 2 galaxies show significant intrinsic X-ray absorption with column densities around 10²² cm⁻².

The stakes: Insufficient data on some sources, like the radio-loud SRGA J000132.9+240237, limits understanding of AGN physics and absorption.
