B Ultramassive Black Hole (UMB), 30 billion solar masses?

AI Thread Summary
Astronomers have discovered an ultramassive black hole exceeding 30 billion solar masses, one of the largest ever recorded, using gravitational lensing. This technique allows the detection of distant black holes by observing the bending and magnifying effects of light from nearby galaxies. The European Space Agency's upcoming Euclid mission, set to launch in July 2023, is expected to significantly enhance black hole research by identifying around 100,000 new gravitational lenses. This could lead to the discovery of thousands of previously hidden black holes. The findings mark a pivotal advancement in understanding the upper limits of black hole sizes.

Paris (AFP) – One of the largest black holes ever recorded has been discovered using a new technique that could spot thousands more of the insatiable celestial monsters in the coming years, according to astronomers.

The ultramassive black hole, one of just four ever observed, is more than 30 billion times the mass of the Sun, a new study said.

It is the first black hole ever observed using a phenomenon called gravitational lensing, in which light travelling towards us from a distant galaxy appears to magnify and bend inwards, giving away the presence of a dark giant.

James Nightingale, an astronomer at the UK's Durham University and the study's lead author, told AFP the process was "similar to shining light through the base of a wine glass".

There are currently around 500 known gravitational lenses -- at least one of which we now know is a supermassive black hole.

But "the landscape is about to dramatically change," Nightingale said.

The European Space Agency's Euclid mission, planned to launch into space in July, will open a "big data era" for black hole hunters by creating a huge high resolution map of the universe, he said.

In the next six years Euclid could find 100,000 new gravitational lenses, which would potentially point towards thousands of previously hidden black holes, Nightingale added.

"Lead author Dr James Nightingale, of the Department of Physics at Durham University, said: "This particular black hole, which is roughly 30 billion times the mass of our sun, is one of the biggest ever detected and on the upper limit of how large we believe black holes can theoretically become"

Is it the largest or one of the largest?
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
