a starburst galaxy
According to the pattern of the rotation velocity curve of M82 (NGC3034)'s disk, it is not a spiral galaxy.
The filaments extending perpendicular to the galaxy disk are made of ionized hydrogen gas emitting red light.

How can we explain the shape of this explosion?
The Spherical Harmonics are functions defined on the sphere, which are used to describe the wave function of the electron in a hydrogen atom. In this case, the shape is based on |Y20|2.
|This is the image of NGC4261, located 45 million light-years away from the Earth. Two jets are emanating from the nucleus to the opposite directions and spanning a distance of 88,000 light-years. There should be a black hole in the center of the disk. A lot of hot gas squirts out from the black hole's two holes to create the radio jets. These jets are aligned perpendicular to this disk. |
The point is that the potential distribution of the gravity of this black hole may not be spherical in relation with the strong light or emission. It is like a phase metastasis between gravity and emission.
