Optical image of the galaxy group with 3-colour optical images of each member galaxy using data from the Hyper-Suprime Camera on the Subaru telescope. The red outline indicates the extent of the neutral hydrogen gas around each galaxy. (Credit: Shilpa Ranchod/MIGHTEE/HSC project)
A 3-colour optical image from the Hyper-Suprime Camera on the Subaru telescope of two of the group galaxies. The diffuse red structure is the neutral hydrogen gas, which envelops both galaxies, and indicates they are in the process of merging. (Credit: MIGHTEE/HSC Project)
This gif shows resolved rotational velocity maps of a subset of MIGHTEE-HI galaxies.
Red shows gas that is moving away from the observer, and blue show gas moving towards us.
