These are supermassive black holes, and they've been critical to the universe's evolution. A new study, published today in the journal Nature, offers a fascinating new method to measure their spins.
Astronomers observed the black hole in detail using the International Space Station's NICER telescope, finding that it experienced a shift in X-ray intensity every 15 days, aiding in estimating its spin speed.
The researchers suggest this new technique can help solve mysteries about the evolution of galaxies, shedding light on how Cosmic Dawn led to the formation of galaxy cores we see today.
