Unveiling the Secrets of our Galaxy’s Supermassive Black Hole

News Release • July 15, 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.

Brightest Cosmic Explosion Ever Detected Had Other Unique Features

News Release • June 8, 2023

When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Most gamma-ray bursts occur when the core of a star more massive than our Sun collapses, becoming a black hole. These events regularly release as much energy in a few minutes as our Sun will release in its entire lifetime.

NASA Study Helps Explain Limit-Breaking Ultra-Luminous X-Ray Sources

News Release • April 6, 2023

In a recent study published in The Astrophysical Journal, researchers report a first-of-its-kind measurement of a ULX taken with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR). The finding confirms that these light emitters are indeed as bright as they seem and that they break the Eddington limit.

Black holes can tell us the expansion rate of the Universe

News Release • November 10, 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.
