XRISM measured hot gas in M82 moving outward at more than 3.2 million kilometers per hour.
The gas temperature is reported at about 25 million degrees Celsius.
The result supports stellar wind and supernova shockwaves as the main drivers of the galaxy’s outflow.

XRISM directly measured superheated gas in M82 moving at more than 2 million miles per hour.
Researchers say the hot outflow appears to drive the galaxy’s larger cool wind.
The result was published in Nature and helps test long-standing models of starburst feedback.

XRISM detected the most violent turbulence ever recorded in a galaxy cluster, centered on black hole M87*
The spacecraft can measure gas velocities around black holes for the first time, a capability no previous X-ray telescope possessed
Gas velocities are highest near the black hole and drop off rapidly, driven by turbulent eddies and outflowing shockwaves
The findings explain how black holes regulate cooling in galaxy clusters through active galactic nucleus feedback
Results were published in Nature and represent XRISM's showcase achievement since its 2023 launch
