Characteristics
NGC 5920 has an active galactic nucleus. It presents a radio jet. In addition, it hosts a radio source in its core called 3C 318.1, indicating emissions of strong radio waves.{{Cite journal |title=The Spectra of Radio Sources in the Revised 3c Catalogue |url=https://adsabs.harvard.edu/full/1969ApJ...157....1K |access-date=2024-04-16 |journal=The Astrophysical Journal|bibcode=1969ApJ...157....1K |last1=Kellermann |first1=K.

The research was further improved by following the cold gas phase and through study of intensive ratios in emission lines that caused the excitation. Researchers found that, there was a spatial connection between the filaments that are cold and having lower metal abundance levels.
Group Membership
NGC 5920 is the brightest cluster galaxy of a small galaxy cluster which is known as MKW 3.{{Cite journal |last1=G.A. |first1=Kriss |last2=C.R. |first2=Canizares |last3=J.E. |first3=McClintock |last4=E.D. |first4=Feigelson |date=1980 |title=Detection of extended X-ray emission surrounding cD galaxies in poor clusters |url=https://inis.iaea.org/search/search.aspx?orig_q=RN:11539792 |journal= The Astrophysical Journal|language=en |volume=235 |issue=2|pages=L61 |doi=10.1086/183159 |bibcode=1980ApJ...235L..61K |url-access=subscription }}{{Cite journal |last1=Jimenez-Gallardo |first1=A. |last2=Massaro |first2=F. |last3=Balmaverde |first3=B. |last4=Paggi |first4=A. |last5=Capetti |first5=A. |last6=Forman |first6=W.
