In 1993, the source was confirmed as a Seyfert type 1 galaxy by Remillard and colleagues, who identified several emission-line AGNs from a further HEAO-1 X-ray survey.Remillard R. A. Bradt H. V. D.

The most likely explanation for this energy source in all active galactic nuclei is a presence of an accretion disk around a supermassive black hole. The mass of the black hole in center of 1H 0323+342 is estimated to be 107 M☉ based on the width and luminosity of a Hβ line and empirical scaling relations, or ~ 2 × 107 M☉ according to multi-wavelength observations.Pan Hai-Wu Yuan Weimin Yao Su Komossa S.

In 2016, a similar mass of (3.4+0.9-0.6) × 107 M☉ was found from a reverberation study.Doi Akihiro Hada Kazuhiro Kino Motoki Wajima Kiyoaki Nakahara Satomi 2018-04-10 A Recollimation Shock in a Stationary Jet Feature with Limb-brightening in the Gamma-Ray-emitting Narrow-line Seyfert 1 Galaxy 1H 0323+342 The Astrophysical Journal Letters 857 1 L6 10.3847/2041-8213/aabae2 free 1804.03776 2018ApJ...857L...6D 2041-8205 However, in 2024, the mass is 107.24±0.01 M☉ according to the galaxy's total flux spectrum.Jose Jincen Rakshit Suvendu Panda Swayamtrupta Woo Jong-Hak Stalin C S Neha Sharma Pandey Shivangi 2024-07-11 Spectropolarimetric view of the gamma-ray emitting NLS1 1H0323 + 342 Monthly Notices of the Royal Astronomical Society 532 3 3187–3197 10.1093/mnras/stae1691 free 0035-8711 2407.06761 Additionally, the nucleus shows a quasi-stationary feature similar to a HST-1 structure inside the jet of Messier 87. 1H 0323+342 shows some characteristics of blazars, including variable fluxes in optical, radio and X-ray bands as well as a compact bright core.Zhou Hongyan Wang Tinggui Yuan Weimin Shan Hongguang Komossa Stefanie Lu Honglin Liu Yi Xu Dawei Bai J.
