Supermassive black holes have been discovered to grow
more rapidly in young galaxy clusters, according to new
results from NASA's Chandra X-ray Observatory.

Can any one tell me how they confirmed it as a 'black hole'?

Energetic emission indicates stuff falling in to either a neutron
star or a black hole. There may be no characteristic emissions
of striking the surface of a neutron star, which have been
observed elsewhere. Additionally, the mass of a single object is
too large to be a neutron star. So it would have to be a cluster
of orbiting neutron stars... with no discernable periodicity, and
nothing ever "lands" where we can see it, or even reflections of
it.
