[7] A radio continuum tail can seen extending outwards from the galaxy, showing widespread occurrence of relativistic electrons and magnetic fields which is being removed by pressure.

This shows increased radial velocities which reaches up between 400 and 800 kilometer per seconds within distance from the nucleus of the galaxy.

[8] Not to mention, a low velocity filament is found at the southeastern edge of IC 4040 which exhibits blue continuum and strong Hα emission.

[8] IC 4040 also presents a strong radio source compared to galaxies of type E/SO.

[10][11] SN 2022jo[12] was discovered in IC 4040 on January 9, 2022, by a group of astronomers; Chunpeng Bi, Jianlin Xu, Mi Zhang, Jingyuan Zhao, Guoyou Sun, Jiangao Ruan and Wenjie Zhou from Xingming Observatory.
