A Strange Black Hole Is Shooting Out Wobbly Jets Because It’s Dragging Spacetime

A Strange Black Hole Is Dragging Spacetime And Shooting Out Wobbly Jets
Astronomers are currently analyzing the information from that single event since it included so much information. And scientists have now come upon a remarkable phenomenon: relativistic jets that wobble so quickly that a change in direction may be noticed in a matter of minutes.

And when they do this, they blast up fast plasma clouds.

Astrophysicist James Miller-Jones of the International Centre for Radio Astronomy Research (ICRAR) at Curtin University in Australia stated back in April, “This is one of the most remarkable black hole systems I’ve ever come across.”

A black hole that is nine times as massive as the Sun and an early red giant companion star make up the binary microquasar system known as V404 Cygni.

The red giant is being progressively ingested by the black hole, while the star’s material is being sucked away and is encircling the black hole in the shape of an accretion disc, which resembles water circling a drain. Extremely dense, hot, and radiant areas make up the nearest parts of the disc, and as it consumes matter, the black hole emits strong plasma jets that are most likely coming from its poles.

The specific process underlying jet formation is unknown to scientists. They believe that material from the accretion disc’s innermost rim is funneled along the magnetic field lines of the black hole, which serve as a synchrotron to accelerate the particles before expelling them at extremely high speeds.

The erratic jets from V404 Cygni, however, are in a league of their own, blasting out in various directions at various times, on such rapidly varying timelines, and at speeds up to 60% the speed of light.

According to Miller-Jones, “we believe the disc of material and the black hole are out of alignment.” As a result, the interior portion of the disc seems to be wobbling like a spinning top and shooting forth jets in various directions as it changes position.

Frame-dragging is an event that Einstein predicted would occur in his general theory of relativity. A revolving black hole’s gravitational pull is so strong that it almost drags spacetime along with it as it rotates. (This was one of the outcomes researchers wanted to see when they snapped a photo of Pōwehi.)

The accretion disc for V404 Cygni is approximately 10 million kilometers (6.2 million miles) wide. The inner few thousand kilometers of the accretion disc have been deformed due to the black hole’s spinning axis being out of line with it.

The distorted portion of the disc is subsequently pulled along with the black hole’s spin by the frame-dragging effect, which sends the jet flying out in all directions. The interior portion of the accretion disc is also inflated like a solid doughnut and rotates.

The fast precession we observe in V404 Cygni can only be explained by this process, according to Miller-Jones.

The typical approach radio telescopes utilize to see space was almost ineffective due to its speed. These instruments often use long exposures, travelling across the sky to monitor their target while viewing a region for several hours at a period. But in this instance, the technique led to photos that were too blurry to be useful.

The team had to switch to a different technique, which included stitching together 103 individual photos with exposure durations of barely 70 seconds to make a movie. Sure enough, the crew saw the wibbly, wobbly spacetimey jets.

Physicist Greg Sivakoff of the University of Alberta commented, “We were gobsmacked by what we discovered in this system – it was entirely unexpected.”

“Finding this astronomical first has deepened our understanding of how black holes and galaxy formation can work. It tells us a little more about that big question: ‘How did we get here?'”
