Observations of the matter surrounding black holes shed new light on their inner workings. Find out more at 🚀
Scientists made new observations of a stellar-mass black hole called Cygnus X-1 and discovered never-before-seen details regarding the configuration of extremely hot matter surrounding the cosmic giant.
Matter is heated to scorching temperatures as it's sucked into the vicinity of a black hole, making it glow in X-ray observations. As per , the researchers used measurements of the polarization of X-ray observations to refine models that describe the elusive behavior of these celestial beasts.Cygnus X-1 has the mass of 21 Suns and it is one of the brightest X-ray sources in the Milky Way. It also has a 41 solar mass companion star in orbit., are the first observations of a mass-accreting black hole captured by the Imaging X-Ray Polarimetry Explorer mission.
"Previous X-ray observations of black holes only measured the arrival direction, arrival time, and energy of the X-rays from hot plasma spiraling toward the black holes,” explained lead author Henric Krawczynski, from the Washington University in St. Louis. "IXPE also measures their linear polarization, which carries information about how the X-rays were emitted — and if, and where, they scatter off material close to the black hole.
Though no light can escape from the event horizon of a black hole, IXPE is able to detect X-rays emitted by the hot plasma, or matter, roughly 1,240 miles away from the event horizon. The researchers combined this data with observations made at the same time by NASA's NICER and NuSTAR X-ray observatories. This allowed them to carefully analyze the geometry of the plasma.
