Intermediate - mass black holes are thought to form either from the merging of several smaller, stellar - mass black holes, or as a result of a collision between massive stars in dense clusters.

In terms of mass they lie between the more commonly found stellar - mass and supermassive types of black hole [3], and could tell us about how black holes grow and evolve within clusters like Messier 15, and within galaxies.

Generally, black holes with masses between about 100 and about 100,000 times that of the Sun are called «intermediate - mass black holes,» although there is no strict definition for the mass range.

But they are thought to be the crucial missing link between black holes about 10 times the mass of the Sun and those millions or billions of times more massive, both of which have been documented.

While the black hole discovered in 2011 in the galaxy NGC 4889 in the Coma Cluster was estimated to have an upper limit of 21 billion solar masses, its range of possible masses was large: between 3 billion and 21 billion suns.

If a runaway star accumulates between 800 and 3000 times the Sun's mass before exploding as a supernova, it can produce a midsize black hole whose mass is 100 to 1000 times the Sun's.

Both papers provide new, closely related estimates for the mass of the suspected black hole and the distance between our sun and the galactic center, roughly 26,000 light - years away.

In this scenario, you would expect to see a distribution of black hole masses, with intermediate - sized black holes (those between 105 and 107 solar masses) in numbers orders of magnitude greater than what we see in our local universe.

The afterglow shows that the merger spewed between 0.1 and 0.2 solar masses of newly formed radioactive elements into space, more than could have escaped from a black hole.

Meanwhile, a correlation between the rate at which stars form in the central regions of galaxies and the amount of gas that falls into supermassive black holes (mass accretion rate) was known to exist, leading some scientists to suggest that the activity involved in star formation fuels the growth of black holes.

«We want to find intermediate - mass black holes because they are the missing link between stellar - mass and supermassive black holes.

The galaxy could continue to grow in the future, but the relationship between the mass of the black hole and that of the stars would remain unusually large.

Researchers have spotted hints of much rarer medium - size black holes, which harbor between 100 and several hundred thousand solar masses.

Supermassive black holes can have anywhere between a few million and a few billion solar masses, and are present at the center of all galaxies.

This discovery will enable astronomers to compare the properties of black holes gleaned from gravitational wave observations with those of similar - mass black holes previously only detected with X-ray studies, and fills in a missing link between the two classes of black hole observations.

Evidence has been accumulating for several decades that most galaxies harbor central mass concentrations that may be in the form of black holes with masses between a few million to a few billion times the mass of the sun.

«Astrophysicists have been collecting observational evidence for both stellar mass black holes and supermassive black holes for decades, but even though we think the largest ones grow from the smallest ones, we've never really had clear evidence for a black hole with a mass in between those extremes,» she added.

It appears that the relationship between nuclear black hole mass and other properties of late - type galaxies remains to be understood.

In the nearby Universe, there is a direct relationship — a constant ratio — between the masses of the black holes and that of the central «bulges» of the galaxies.

Hubble observations have helped astronomers conclusively find supermassive black holes in some host galaxies, but even more surprising was the observed connection between the mass of a supermassive black hole and the size of its host galaxy.
