Ultra Massive Black Holes:

Thanks to data collected by NASA's Chandra X-ray telescope on galaxies up to 3.5 billion light years away from Earth, an international team of astrophysicists has detected what are likely to be the most massive black holes ever discovered in the universe. The team's calculations showed that these ultramassive black holes are growing faster than the stars in their respective galaxies.

"The results showed that the masses of ultramassive black holes are roughly 10 times greater than those originally projected. Furthermore, almost half of the sample's black holes are estimated to be at least 10 billion times more massive than the sun. This puts them in a class of extreme heavyweights that certain astronomers call "ultramassive black holes."

"We have discovered black holes that are far larger and way more massive than anticipated," Mezcua says. "Are they so big because they had a head start or because certain ideal conditions allowed them to grow more rapidly over billions of years? For the moment, there is no way for us to know."

OK, I remember reading results of the WMAP probe  and the data that revealed the first stars formed around 200 million years post BB. And its common knowledge that these GEN 1 first stars, that formed from the actual stuff of the BB itself, H and He [POP III]  were many times more massive then current stars, plus they had relatively short life spans in the 10's of millions of years before going S/nova or Hypernova: So, my question, are these ultra massive BHs really that surprising?
