Black holes has been a theoretical mathematical concept
since the late nineteenth century
The name 'black holes' was actually coined in the 1950s
by John Wheeler
And we first identified the first supermassive black hole
or quasar, using the Parkes radio telescope.
And we were looking at 3C 273.
Now most people are fascinated by the very extreme phenomena
that is black holes, because the gravity in a black hole
is so strong that not even light photons can escape.
Now that's pretty mind boggling.
Professional astronomers talk about black holes all the time
because they're everywhere, in pretty much every galaxy.
And range from stellar mass black holes
to central supermassive black holes
Which have masses a few hundred million times the mass of our Sun.
There are still many open questions left in the field
of how galaxies and supermassive black holes co-evolve
and we've also seen supermassive black holes in the early Universe
How do they become so massive so quickly?
So how do supermassive black holes grow and effect galaxy evolution?
That's something we'd like to find out.
