XRISM Spacecraft will Open New Window on the Xray Cosmos

Scientists studied NGC 7319, part of the visual grouping of galaxies called Stephan’s Quintet, using the Medium-Resolution Spectrometer (MRS) in the Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope. The galaxy contains a supermassive black hole that is actively accreting material. The spectrometer features integral field units (IFUs) – each containing a camera and spectrograph. IFUs provided the Webb team with a collection of images of the galactic core’s spectral features, shown here. Blue-colored regions indicate movement toward the viewer and orange-colored regions represent movement away from the viewer. Powerful radiation and winds from the black hole ionize hot spots of super-heated gas, creating the argon and neon lines...
