NASA Telescope Spots Temperature Swings of Black Hole Winds For The First Time

The winds, according to new measurements of a nearby supermassive black hole obtained with NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) telescope, can heat up and cool down in the span of just a few hours. The black hole is located in the active galaxy IRAS 13224-3809 in the constellation Centaurus. Scientists report these findings, using data from NuSTAR and European Space Agency’s XMM-Newton telescope, in the journal Nature.

“We know that supermassive black holes affect the environment of their host galaxies, and powerful winds arising from near the black hole may be one means for them to do so,” says NuSTAR Principal Investigator Fiona Harrison, professor at Caltech in Pasadena. “The rapid variability, observed for the first time, is providing clues as to how these winds form and how much energy they may carry out into the galaxy.”
