Description

M106 is a large spiral galaxy inclined to our line of sight that is has been classified as a Seyfert 2 type with an active nucleus and disturbed spiral arms, probably from an encounter with one of its neighbouring galaxies, possibly NGC 4217. It is also of interest because it appears to have two sets of spiral arms with those in the optical not matching up with those seen in the radio and X-ray. The radio and X-ray arms appear between the main optical arms as ghostly apparitions. M106 also has radio jets from the activity in its central region. And it is likely that these arms are being caused by the main jets being tipped at angle of 30 degrees to the disk and as they pass causing shock waves that propagate into the disk heating the gas.
