James Webb ha descubierto una galaxia extinguida por un agujero negro supermasivo que se convirtió en cuásar


Scientists have discovered a galaxy in which star formation has stopped. The James Webb Space Telescope has helped.

this is what we know
GS-9209 is the oldest known extinct galaxy. Almost all of its stars appeared between 600 and 800 million years after the Big Bang. However, the star formation stopped suddenly.

Over 200 million years, GS-9209 was capable of accumulating the mass of 40 billion suns, the mass of the Milky Way. Scientists believe that the sudden cessation of star formation may be due to the behavior of a supermassive black hole at the center of the galaxy.

According to astronomers at the Royal Observatory in Edinburgh, the black hole has become a quasar that emits 1 trillion times more radiation than stars in the process of absorbing matter. This is enough to prevent the gas needed to form stars from contracting.

The researchers now plan to study the galaxy GS-9209 in more detail. The Extra Large Telescope of the European Southern Observatory will help them do this. But the observatory is still under construction.
