List of most massive black holes

There is something wrong with the Universe again, 3 massive BH’s have gone over the Theoretical limit.

Physical limits must be different to theoretical limits.

1. Phoenix A 1×10 ¹¹
2. TON 618 6.6×10 ¹⁰
3.4C +74.13 5.13+9.66−3.35×10 ¹⁰

(Theoretical limit) 5×10 ¹⁰

4. Holmberg 15A (4.0±0.8)×10 ¹⁰
5. IC 1101 (4–10)×10 ¹⁰

Q Is there any way to move the “power” closer to the numbers ?

One does wonder what margin of errors exist for both, I’d assume though that’s taken into account

It’s not the universe it’s the physics.

There’s a theoretical limit?
With or without dark matter?

> “The above masses are larger than what is predicted by current models of black hole growth”

Oh, “current models of accretion”, exceeding those is not too surprising. By “current models of accretion”, Neptune can’t exist, because it’s greater than the maximum size for a planet accreting that far from the Sun.

> 5*10^10 solar masses
> This is the maximum mass of a black hole that models predict, at least for luminous accreting SMBH’s. At around 10^10 M☉, both effects of intense radiation and star formation in the accretion disc slows down black hole growth. Given the age of the universe and the composition of available matter, there is simply not enough time to grow black holes larger than this mass. Reported for reference.

Dubious on a couple of counts. One is that it assumes an angular momentum for the accretion disk. As the spin of the accretion disk drops to zero, so the maximum size increases without upper bound. As the size of a black hole grows, the radiation from it decreases rather than increasing. Not only does the intensity of Hawking radiation drop towards zero, but also radiation from tidal disruption of matter falling in drops towards zero.

Wouldn’t the mass of black holes depend on the local environment, denser regions create heavier black holes.

I think this is the case.

Even more than that. A higher density of dark matter would create a bigger black hole. I’m not sure that anyone knows what happens to dark matter in an accretion disk.

A computer simulation going forwards and backwards?

> A computer simulation going forwards and backwards?

Huh?

Set initial parameters, such as random distribution and velocity of matter and dark matter, and track it.

… or …

Set initial parameters to be accretion disk density distribution and angular velocity, and track it.

In both cases, the smaller the assumed initial velocity, the larger the black hole can grow.

Another way to get the simulation to generate a bigger black hole would be to start with the black hold swallowing dark matter and gas. And then switch off the gas and switch on solid asteroids and planets, and stars.
