Universe's biggest blackhole discovered inside a tiny dwarf galaxy!
What could be nearly the universe's biggest blackhole has been
discovered inside a galaxy that is just 1/4 the size of the Milky Way. Until now it was assumed blackholes grew to this size only in really big galaxies. In fact, it was thought that there was a standard defacto blackhole-to-galaxy mass ratio rule. Looks like that was wrong! Big Time!!! Typically they expected the galaxy's central blackhole to be less than 1% the mass of the rest of the galaxy. In this case it's 14% the mass of its host galaxy. It raises questions about how exactly supermassive blackholes formed in the universe in the first place. Do the blackholes grow to their sizes through mergers and accretion, or do they form pretty much at their current sizes? It's obviously a combination of the two, but which one is the main forming process? I've personally always thought the blackholes came first as localized density differences during the Big Bang, and then later the stars & the galaxies formed around them like foam forming around a drain.

"current masses" might be a better choice of words. It's obviously a combination of the two, but which one is the main forming process? I've personally always thought the blackholes came first as localized density differences during the Big Bang, and then later the stars & the galaxies formed around them like foam forming around a drain. Sounds like that is close enough to me. David A. Smith |

How does one follow the other? Blackholes are definitively understood objects, whereas dark matter and energy aren't yet, so they can't be of the same origin.

Sounds like that is close enough to me. Great, then we're in violent agreement. Yousuf Khan |

This one is clearly breaking all the established rules, and perhaps aether has a little something to do with its enormous mass. Is this one the start of a new galaxy, or is it the demise of an old galaxy? |

TeBet My own opinion is that the supermassive blackholes came first, probably came within nanoseconds after the Big Bang, and as a result of the BB too. Localized density fluctuations during the BB may have been the start of these blackholes, and not stars imploding on themselves. These blackholes may have existed long before the first stars or galaxies started. They were created in the BB, and as the universe spread out quickly due to Inflation, these blackholes got separated from each other, thus providing the numerous anchor points around which the gas eventually accumulated to form the stars & galaxies, after Inflation ended. How massive these blackholes initially were was probably not too important, just as long as they attained a certain minimal mass, that could act as the anchor points of the galaxies that eventually formed around them. After all it doesn't matter if you have a big boat anchor or a small boat anchor, if the anchor is good enough to hold the boat in place, that's all you needed. Thus we're living in a relatively large galaxy, with a comparatively small blackhole, which was probably just adequate to get our galaxy started. However, in the case of NGC-1277, they got an over-endowed boat anchor for the size of galaxy they have. Another possibility is that this blackhole was the anchor for a much larger galaxy at one time. That original galaxy may have been involved in a merger event with another galaxy. We often see that when a three-way merger is involved with blackholes, the smallest blackhole eventually gets kicked out of the newly merged galaxy. The kicked blackhole usually leaves with a cadre of its closest stars, basically forming a star cluster surrounding it. This blackhole is so large, its attendant star cluster must've been about the size of a dwarf galaxy! Also if this is the runt blackhole that got kicked out, can you imagine how big the other two blackholes that eventually kicked it out were?!? Yousuf Khan |

Is this one the start of a new galaxy, or is it the demise of an old galaxy? It could be both, see my discussion with Herb. I listed a hypothesis that this blackhole may have anchored a far bigger galaxy at one time, but then it got kicked out and is now just anchoring this left-over remnant of stars. Yousuf Khan |

Clearly not true for Dark Matter. Dark Matter will / does have a contribution from MACHOS (inclusive of black holes), WIMPS (however unlikely from many other recent observations), unexpectedly ionized normal matter, and whatever is left some exotic stuff. The black holes cannot have consumed much normal matter, or Dark matter will have been seen to increase. David A. Smith |
