An article being published in "The Astrophysical Journal" reports the results of the study of two galaxy mergers between dwarf galaxies with active galactic nuclei. A team of researchers used data collected by NASA's Chandra X-ray Observatory to discover candidates and then compared them with infrared and optical frequency observations.

Thanks to SRG/#eROSITA's contiguous 140 square degrees pilot survey field, we constructed a large, complete, and unbiased soft X-ray flux-limited AGN sample at low redshift 0.05<z<0.55: https://arxiv.org/abs/2301.01388
