A 3 billion solar mass black hole rockets out of a galaxy

From Phil Plait Fri, Mar 24, 2017 8:00am, The Bad Astronomer:
A 3 billion solar mass black hole rockets out of a galaxy at 8 million kilometers per hour. Yes, seriously.

In astronomy, you deal with a lot of ridiculously violent cosmic phenomena. Stars explode, asteroids collide, whole galaxies smash together. When you look at the math and physics, when you actually grasp the levels of power involved, it’ll make the hair on the back of your neck stand up. It’s chaos wielded on a mind-crushing scale.

And then there’s the “two supermassive black holes colliding and merging and then launching the resulting even larger billion-solar-mass black hole out of a galaxy at nearly 8 million kilometers per hour due to gravitational waves” scale of immensity.

Holy. WOW.

And from the Hubble web site, spacetelescope.org:
Hubble detects supermassive black hole kicked out of galactic core

Though several other suspected runaway black holes have been seen elsewhere, none has so far been confirmed. Now astronomers using the NASA/ESA Hubble Space Telescope have detected a supermassive black hole, with a mass of one billion times the Sun’s, being kicked out of its parent galaxy. “We estimate that it took the equivalent energy of 100 million supernovae exploding simultaneously to jettison the black hole,” describes Stefano Bianchi, co-author of the study, from the Roma Tre University, Italy.

The images taken by Hubble provided the first clue that the galaxy, named 3C186, was unusual. The images of the galaxy, located 8 billion light-years away, revealed a bright quasar, the energetic signature of an active black hole, located far from the galactic core. “Black holes reside in the centres of galaxies, so it’s unusual to see a quasar not in the centre,” recalls team leader Marco Chiaberge, ESA-AURA researcher at the Space Telescope Science Institute, USA.

I suppose that's one way of describing a black hole

It'll certainly leave a mark.

It won't, that's kind of the point of a black hole, it won't leave anything except a gap where things used to be.

Ok maybe you could call that a mark.

This is not just limited to black holes. Betelgeuse is on a similar galactic trek and will certainly leave anything in its wake either. It is moving at a rather more modest pace compare to this black hole though, a mere 108000Kmh, with a bow shock 4 light years wide.
