Black hole pairs in merging galaxies

[Lismore Bloke]

Fascinating press release detailing the discovery of 16 close pairs of black holes in merging galaxies. It makes you wonder if our own black hole has grown through merging of dwarf galaxies.

Thanks for that Paul:thumbsup::thanx:.
I do like to think our galaxy is gobbling up other galaxies certainly there is evidence of such..what was that one they found recently??? must have a look.
I was surprised the distance between the black holes seemed huge...I wonder what the orbit is for the closest black hole binaries???

Is it flooding in Lismore ??? I have no radio or TV here and have not run into anyone who knows helpful detail.

:question: That's if our galaxy is the Milky Way, and we're not just prisoners of the beast that swallowed our very own black hole Alex! ;) :lol:

Rob I think you may be onto something ... clearly "they" would keep such information from us ... and your idea is more credible than all of the stuff I have read today (apart from the posts and links given by this most wonderful forum)...

The galaxy I was thinking of was Sagittarius Dwarf Elliptical Galaxy (SagDEG) but it is still a satellite galaxy ...but I am sure I read about someone finding evidence that we have eaten something similar...

Hi Alex and Rob,

Thanks for commenting. Everything is OK in Lismore. We were lucky that the weather system that caused so much grief in Qld went south west from there and missed us. Another smaller rain band went roughly parallel to that and hit the Clarence. We were between the two - lucky us!

I love the idea of galaxies gobbling each other up like giant Pac men. I think I read somewhere that the globular Omega Cen. is thought to be the core of a dwarf galaxy that our milky way absorbed and other globulars are also galaxy cores. The following link has another interesting article on the Magellanic Clouds. Cheers, Paul.
