Unexpected Rotational Motion Detected in Ultra-Diffuse Galaxies of Hydra Cluster
Astronomers studying ultra-diffuse galaxies (UDGs) in the Hydra cluster have observed unexpected rotational movement in nearly half of the 30 galaxies examined. Spectroscopic data from the LEWIS programme, using the MUSE instrument on the Very Large Telescope, suggests that gravitational interactions with larger galaxies may influence their formation. A closer look at...
