Galactic Outflow in Starburst Galaxy M82 Shows Supersonic Movement

A new study, accepted for publication, details observations of supersonic motion within the outflow region of the starburst galaxy M82. Utilizing high-resolution spectral data from XRISM, researchers have gained new insights into the temperatures of the galactic wind and its velocity dispersion. This research contributes to a deeper understanding of the mechanisms driving galactic outflows.
