Globular Clusters are swallowed Galaxies

[Widdekind]

Computer Simulations suggest that:

hundreds of medium-sized

Black Holes

are roaming loose in the

Milky Way

. These rogues... are the

orphaned

Central Black Holes

of the many smaller

Galaxies

that the

Milky Way

has swallowed

over its

billions of years

of existence.

For:

Galaxies

, such as our own, most often grow by absorbing smaller, satellite galaxies, such as the

Large Magellanic Cloud

, which orbits the

Milky Way

.

And:

each of the hundreds of billions of

Galaxies

in the

Cosmos

formed a massive or supermassive

Black Hole

at its center [and] when big

Galaxies

collide -- a relatively common occurrence -- their central

Black Holes

eventually merge.

But:

sometimes the central

Black Hole

of a

Dwarf Galaxy

might remain independent after a

Galactic Collision

... The ejected

Black Hole

would not move fast enough to escape the

Galaxy's

gravity entirely

, but it would move faster than the background stars--something that makes it detectable, because it would also be dragging along a

small cluster of surrounding stars

... the researchers suggest searching the galaxy for compact and relatively fast-moving

clusters of old stars

*

.

Now, "compact clusters of old stars" sounds suspiciously like Globular Clusters:

supermassive

Globular Clusters

are in fact the cores of

Dwarf Galaxies

that are consumed by the larger

Galaxies

.

Several

Globular Clusters

(like

M15

[in our

Milky Way Galaxy

,

33.6 thousand light-years away

, in

Pegasus Constellation

]

)

have extremely massive Cores which may harbor

Black Holes

...

 

a

4,000 Solar-mass

Intermediate-mass Black Hole

has been suggested to exist

, based on HST

[

Hubble Space Telescope

]

observations,

in the

Globular Cluster

M15

, and a

20,000 Solar-mass

Black Hole

in the

Mayall II

cluster in the

Andromeda Galaxy

. Both x-ray and radio emissions from Mayall II appear to be consistent with an intermediate-mass black hole.

 

These are of particular interest because they are the first black holes discovered that were intermediate in mass between the conventional stellar-mass

Black Hole

and the supermassive

Black Holes

discovered at the cores of

Galaxies

.

The mass of these

Intermediate-mass Black Holes

is proportional to the mass of the clusters, following a pattern previously discovered between

Supermassive Black Holes

and their surrounding

Galaxies

**

.

This strongly suggests, that Globular Clusters are ancient Dwarf Galaxies, having "Dwarf Black Holes" at their cores.

Nice info Widdekind, thanks for sharing. I understood you 100% this time. Let's be on the lookout for an entourage of stars following a medium massive black hole thru our galaxy.

 

How do you think supermassive black holes originally formed? I seems to me they must have formed at the time of the big bang because how does that much matter, Millions or Billions of solar masses, get close enough together to create a SBH? Stars are too disbursed and have too much motion to all fall together like that.

[granpa]

I read somewhere that gas falling into the center of the galaxy would form a gas disk and would have to lose 99.9% of its angular momentum before it could even get close to the black hole.

[Airbrush]

That is what I mean granpa, there was too much angular momentum, and low density so very little gravity in the swirling expanding masses of gas and dust, for it to all just fall into the middle and become a SBH. The original eddys in the early big bang became SBHs.

[Widdekind]

Perhaps the Big Bang was the Explosive Evaporation of a "Hyper-Massive Black Hole":

Perhaps your SMBHs are "chunks" of BH material blown outwards by that explosion, akin to knots of gas blown out by Supernovae. Those "BH fragments" then formed the seeds of Galaxies w/in our Universe -- to wit, inside the expanding "Explosion Remnant" (akin to Supernova Remnants).
