The most accepted theory for the energy source of active galactic nuclei is the presence of an accretion disk around a supermassive black hole.

[10] The X-ray spectrum doesn't show evidence of obstruction;[8] instead the variation is caused by a change in accretion rate.

Also, during the low activity period, the radius of the circumnuclear dust torus decreased to 32 light days.

[13] A faint parsec-scale radio jet extending 2.8 mas to the north has been detected using very-long-baseline interferometry.

[11] X-ray observations of the galaxy has shown the presence of ultra fast outflows, in the form of blueshifted absorption lines of O viii, Ne ix, Si xiv, and Mg xii.
