I understand why you thought that the black hole in the center of M82 is the source of all that ionized hydrogen filaments, but it is not the case
according to some evidence here:
According to the scientists, the cause of this galactic "superwind" is a collision between its neighbor galaxy M81*.
"Recent evidence indicates that this gas is being driven out by the combined emerging particle winds of many stars, together creating a galactic
'superwind.' The filaments extend for over 10,000 light years. The 12-million light-year distant Cigar Galaxy is the brightest galaxy in the sky in
infrared light, and can be seen in visible light with a small telescope towards the constellation of Ursa Major." Source:
Other pictures of M82:
for an image featuring both galaxies.
"These two mammoth galaxies have been locked in gravitational combat for the past billion years. The gravity from each galaxy dramatically affects
the other during each hundred million-year pass. Last go-round, M82's gravity likely raised circulating density waves rippling around M81 resulting
in the richness of M81's spiral arms. M81, though, left M82 a messy pulp of exploded stars and colliding gas so violent it emits bright X-rays. In
both galaxies, colliding gas has created a recent abundance of bright new stars. In a few billion years only one galaxy will remain."
Btw, the picture of M82 was posted on page 2 of this thread.
*Here is a picture of M81 (the neighbor of M82 that possibly caused the superwind):
