Astronomers tracking supermassive black hole currently on the move through space | Fox 59

(NEXSTAR) — A supermassive black hole is speeding across the galaxy, and astronomers are baffled as to why.

The fast-moving black hole, which is about 3 million times heavier than the sun, is traveling at 110,000 mph about 230 million light-years from Earth, according to researchers at the Center for Astrophysics, Harvard and Smithsonian.

“We don’t expect the majority of supermassive black holes to be moving; they’re usually content to just sit around,” Dominic Pesce, an astronomer at the Center for Astrophysics who led the study, said in a statement . “They’re just so heavy that it’s tough to get them going. “

This jet from a monster black hole is so huge it dwarfs our Milky Way galaxy | Space

Astronomers using NASA's Chandra X-ray Observatory found the jet coming from an object roughly 12.7 billion light-years from Earth, which is pretty early in the universe's 13.77-billion-year-old history . If confirmed, this would be one of the farthest jet-shooting objects of its kind yet known.

The jet comes from an object known as a quasar , which are active galactic nuclei that feed off of supermassive black holes and can emit extraordinary amounts of energy. Astronomers hope that by studying the jet, called PSO J352.4034-15.3373 (PJ352-15 for short), they can learn how huge black holes came together so early in the universe's history.

Astronomers sight wandering huge black hole, but at a safe distance - The Hindu

Astronomers have spotted a supermassive black hole (SMBH) moving on its own. That is, the SMBH is moving with a velocity different from that of its surrounding galaxy.

This is surprising because supermassive black holes usually are not expected to move with respect to the galaxies in whose centres they reside, according to what is known about them so far. Supermassive black holes have masses millions of times the solar mass and inhabit the centres of galaxies. The one at the centre of the Milky Way is named Sagittarius A*.

Supermassive black hole moving at 110,000 mph throughout galaxy, Science News | wionews.com

The Harvard study surveyed ten distant galaxies and the supermassive black holes while specifically studying black holes "that contained water within their accretion disks".

According to Harvard and Smithsonian Center for Astrophysics, a giant black hole is moving throughout the galaxy .

Black Hole in Cygnus X-1 Is So Massive That It Challenges Current Stellar Evolution Models

Measurements from known x-ray binaries have shown that black holes in these systems all have masses below 20 solar masses (M☉), with the largest being 15-17 M☉. However, gravitational wave detections of black hole merger events have found more massive black holes, reaching upwards of 50 M☉, revealing a discrepancy that challenges current theories on black hole formation from massive stars.

Using the new data and archival observations, Miller-Jones et al. refined the distance to the X-ray binary and found it to be farther away than previously estimated, thus raising the inferred mass of the system’s black hole to 21 M☉.

Bay Briefing: 'They're locked in the black hole': Inside the disaster at California's

Good morning, Bay Area. It’s Friday, March 19, and Outside Lands is a go this year — if a bit later. Here’s what you need to know to start your day.

California’s unemployment agency was not prepared for a crisis. Millions of Californians, thrown out of work by shelter-in-place guidelines that started one year ago, turned to the Employment Development Department for unemployment benefits, and the agency was quickly overwhelmed.
