All about the Missing Supermassive Blackhole (recoiling black hole)
Something unusual has been spotted by the researchers in the galaxy cluster of A2261-BCG. A missing supermassive black hole has been reported. Scientists think that this is the first-ever example of recoiling black hole.
A2261-BCG is located at about 2.6 billion light-years from our planet and was studied by Dr Gultekin. This supermassive black hole, estimated to weigh up to 100 billion times the mass of the Sun, is missing. Scientists have been looking for the black hole using the Chandra X-Ray Observatory and Hubble Space Telescope.
Biggest, Youngest Black Hole Ever Shocks Astronomers
The farther away we look, the closer in time we travel back towards the Big Bang. The latest ... [+] record-holder for quasars comes from a time when the Universe was just 670 million years old, revealing a black hole of 1.6 billion solar masses. These ultra-distant cosmological probes show us a Universe that contains dark matter and dark energy, but we do not understand how these black holes grow so large so fast.
In every scientific field, we're always on the lookout for whatever new discovery might reveal what's currently beyond the known frontiers. Searches for smaller, more fundamental particles, temperatures ever-closer to absolute zero, or distant objects at the recesses of the Universe help drive our progress forward.
Oldest quasar and supermassive black hole discovered in the distant universe - CNN
(CNN) The most distant quasar and the earliest known supermassive black hole have been discovered, shedding light on how massive galaxies formed in the early universe.

Bad Astronomy | Most distant quasar found has a too-big supermassive black hole
Astronomers have found the most distant quasar yet seen , and, like a handful of others found at this distance, it presents a huge (literally) problem : The black hole powering it is far too big for how long it's been around.
The quasar is named after its coordinates on the sky, J031343.84−180636.4 (let's call it J0313 for short). It was found in a survey of the sky using Pan-STARRS , the Panoramic Survey Telescope and Rapid Response System, a relatively modest 1.8-meter telescope that nonetheless takes very deep images of the heavens, surveying the sky using different filters to get color information on objects.
After decades of effort, scientists are finally seeing black holes—or are they? | Science | AAAS
General relativity makes very specific predictions about what black holes are and how they should appear, as shown in this simulation.
While working on his doctorate in theoretical physics in the early 1970s, Saul Teukolsky solved a problem that seemed purely hypothetical. Imagine a black hole, the ghostly knot of gravity that forms when, say, a massive star burns out and collapses to an infinitesimal point. Suppose you perturb it, as you might strike a bell. How does the black hole respond?
Astronomers Find Periodically Flaring Black Hole in Distant Galaxy | Astronomy | Sci-News.com
An active galactic nucleus in the center of ESO 253-G003 , an active galaxy over 570 million light-years away in the southern constellation of Pictor, erupts roughly every 114 days, according to a paper to be published in the Astrophysical Journal .

ASASSN-14ko was first detected on November 14, 2014, by the All-Sky Automated Survey for Supernovae (ASAS-SN).
A Black Hole Bites a Chunk Out of This Star Every 114 Days
The explanation? They believe the repeating flares are caused by a supermassive black hole, about 20 times the mass of the one at the center of our own Milky Way, ripping a chunk out of an orbiting star whenever it gets too close.

The discovery was made using NASA data and a network of telescopes operated by The Ohio State University.
"It's really exciting, because we've seen black holes do a lot of things, but we've never seen them do something like this — cause this regular eruption of light — before," said Patrick Vallely, Ohio State graduate student and co-author of a study about the discovery due to be published in The Astrophysical Journal , in a statement .
