Astronomy / Space Rare Supermassive Black Hole Stuns Scientists

[Manticore]

The findings, published in the Monthly Notices of the Royal Astronomical Society, note that the galaxy Fornax UCD3 is part of a set called ultracompact dwarfs (UCDs), a very rare set of galaxies.


“We have discovered a supermassive black hole in the center of Fornax UCD3,” said the study’s lead author, Anton Afanasiev, in a statement. “The black hole mass is 3.5 million that of the sun, similar to the central black hole in our own Milky Way.”

A team of scientists from the Faculty of Physics and Sternberg State Astronomical Institute, MSU, leading an international collaboration with members from Europe, Chile, the U.S. and Australia discovered a supermassive black hole in the center of the Fornax galaxy. The results of the research were published in Monthly Notices of the Royal Astronomical Society journal.

Now, I feel like ... I would say ... crushed

For central galacy black hole it not that extreem.
Andromeda much massive.

Andromeda much massive.

The point in question is that this supermassive black hole is at the centre of a Ultracompact Dwarf Galaxy a type of compact stellar system.

In this paper they say:
"... black hole in the centre of the UCD3 galaxy in the Fornax cluster, which corresponds to 4 per cent of its stellar mass."

So proportionally rather large.

An interesting video.......... thanks!

Do we have any idea of u-compact dwarf galaxies vs. "normal" (either in count or net massiveness)? Or is normal not even useful as a classification?

I’m adding a bit of rock n roll to this thread. Because science deserves it !

Nice groove.
