Default Detecting supermassive galactic black holes that have been kickedout of their galaxies

Sometimes when galaxies merge, the supermassive black hole of one galaxy
doesn't merge with the other galaxy's black hole but instead it gets
kicked out of the system altogether. This is especially likely in the
case of a simultaneous three-way or higher galactic merger. A
"hypercompact stellar system" is the coterie of stars left attached to
and orbiting the kicked-out supermassive. There may be hundreds of these
objects floating around our galaxy, and they may have already been
detected in sky surveys but mistaken to be globular clusters. The speed
at which the stars orbit the supermassive may be a record of how fast
this supermassive was kicked out in the first place.

New Kind Of Astronomical Object Around Black Hole: Living Fossil Records
'Supermassive' Kick
"“You can measure how big the kick was by measuring how fast the stars
are moving around the black hole,” says Merritt, professor of physics at
RIT. “Only stars orbiting faster than the kick velocity remain attached
to the black hole after the kick. These stars carry with them a kind of
fossil record of the kick, even after the black hole has slowed down. In
principle, you can reconstruct the properties of the kick, which is nice
because there would be no other way to do it.”"

Hundreds? On what is this wild assed guess based upon?

This is a spiral galaxy, which severely limits the number of galaxies this
one could have collided with.

It wasn't Yousuf who said that but a scientist. Scientists like to
make
wild assumptions. One third of galaxies are ones that collided
elliptic
galaxies and each made of two galaxies in the past. Since elliptic
galaxies are sums of two galaxies, they also represent the largest
of galaxies. Some may have three or much more number of galaxies
crashing, though a crash won't happen sooner than once in three
billion years, and the Universe is not that old. Sum billions of
random
galaxies, one will find 50 galaxies crashing somewhere and central
black holes flying off in all directions.

Somewhere in a parallel reality, the three smaller dwarfs were stabbed
12 times in a forest.

Parallel Universes are strange. Arriving into them always has this
type of reality to them. Snow White and the four dwarfs. There were
seven dwarfs once.

Besides which, seeing fully-formed galaxies back
to as far as they have seen them pretty much invalidates
the whole theory of how black holes form.

But whatever- fantasize on, the both of you.

Black hole theory was pretty much
invalidated when fully-formed galaxies
were observed as far out as we can see.

It's a theory only morons could accept, anyway.

But you two keep fantasizing.

Think all of the way back to the Milky Way's original formation after
the BB, it grew to this size by swallowing several dwarf galaxies
(supposedly). There may have been thousands of dwarfs that went into
making the Milky Way. Each of those dwarfs contained at least an
intermediate sized supermassive, some of which may have merged with the
main supermassive, some of which may have been kicked out. If even 10%
of them were kicked out, that would still be hundreds of supermassives
floating around, masquerading as globular clusters in the halo.

The new hardline theory of black holes is
"buttsuck the hard line in the buttcrack",
fully formed dark worm in the back between the ass.
Dark worm theory says it is a hardline extremist
reality as far as we can see.

The problem with professional astronomers is that they can't even tell
that Pluto is not a planet. "Nothing can come close to the big"
excludes
that Pluto is valid if it enters Neptune's orbit. Yet we have WASP-17,
a planet which crosses if not all other smaller planets in that solar
system.
So how many planets does that solar system has, one? Of course it has
all those planets as planets. Pluto and the two other small planets
too
are planets. That is my metaphore with murdering the three small
dwarfs
in the Snow White story.

The story you tell is classic of astronomer stories that hundreds of
such
black holes may be found in our galaxy.
