Unveiling the Secrets of our Galaxy’s Supermassive Black Hole

July 15th, 2024

Researchers use X-ray observations from NuSTAR to identify nine previously undetected flares from Sagittarius A*, the relatively dormant supermassive black hole at the center of the Milky Way. X-ray echoes from a nearby molecular cloud reveal that 200 years ago the black hole was 10,000 times more active than it is today.

Black holes can tell us the expansion rate of the Universe

November 10th, 2021

Astronomers have discovered a new way to determine the current expansion rate of the Universe, known as the Hubble constant, using X-ray observations of supermassive black holes at the centre of distant galaxies that are gobbling up huge amounts of gas, known as active galactic nuclei. This could settle an on-going dispute between the two existing methods, which disagree on the age of the Universe by more than a billion years.
