This image shows a quasar, a rapidly growing supermassive black hole, which is not achieving what astronomers would expect from it, as reported in
and radio data from the NSF’s Karl G. Jansky’s Very Large Array reveal some of the evidence for this quasar’s disappointing impact on its host from Earth. Quasars are a rare and extreme class of supermassive black holes that are furiously pulling material inwards, producing intense Quasars are different than other supermassive black holes in the centers of galaxy clusters in that they are pulling in more material at a higher rate.
To reach this conclusion the team used Chandra to study the hot gas that H1821+643 and its host galaxy are shrouded in. The bright from the quasar, however, made it difficult to study the weaker X-rays from the hot gas. The researchers carefully removed the X-ray glare to reveal what the black hole’s influence is, which is reflected in the new composite image showing X-rays from hot gas in the cluster surrounding the quasar.
A paper describing these results has been accepted into the Monthly Notices of the Royal Astronomical Society and is available online. The authors are Helen Russell , Paul Nulsen , Andy Fabian , Thomas Braben , Niel Brandt , Lucy Clews , Michael McDonald , Christopher Reynolds , Jeremy Saunders , and Sylvain Veilleux .
