The James Webb Telescope captures a disturbing image 6 billion light-years away

A new image from the James Webb Space Telescope shows the gravitational lensing effect of a quasar RX J1131-1231Located 6 billion light-years away in the Crater galaxy.

is at the top of the loop Three very bright spots Side by side, with diffraction peaks emanating from them: they are duplicates of a single quasar in the lensing galaxy, duplicated by gravitational lensing. At the center of the ring, the elliptical galaxy appears as a small blue dot that does the lensing effect, ESA said.

It is considered one of the best gravitationally lensed quasars discovered to date, as the foreground galactic background blurs the image of the quasar and creates a bright arc. Four images of the object.

He Gravitational lens effect, first predicted by Einstein, provides a rare opportunity to study regions close to black holes in distant quasars by acting as a natural telescope and magnifying the light from these sources. All matter in the universe changes the space around it, and large masses produce a strong effect.

Around very large objects, such as galaxies, nearby passing light follows this deflected spot and appears to deviate appreciably from its original path. One of the effects of gravitational lensing is that it can Magnifies distant astronomical objectsAllows astronomers to study objects that are very faint or distant.

Measurements of X-ray emission from quasars can indicate the rotation speed of the central black hole, giving researchers important clues about how black holes grow over time. For example, if a black hole grew primarily from collisions and mergers between galaxies, it Accumulating material on a fixed diskAnd the constant supply of new material from the disk leads to a rapidly spinning black hole.

On the other hand, if a black hole grows through many small accretion episodes, it will accumulate material from random directions. The Observations They noted that the black hole in this particular quasar is spinning at about half the speed of light, suggesting that the black hole grew through mergers rather than attracting material from different directions.

This image was taken with Webb’s MIRI (Mid-Infrared Instrument). An observatory program to study dark matter. Dark matter is an invisible form of matter that makes up most of the mass in the universe. Webb’s observations of quasars allow astronomers to probe the nature of dark matter at smaller scales than ever before.
