Ram pressure stripping is a process in astrophysics where a galaxy moving through a high-density environment, such as a cluster of galaxies or a galaxy group, can have its interstellar gas stripped away by the pressure exerted by the surrounding medium. This stripping can remove gas from the galaxy at a rapid rate, ultimately affecting its ability to form new stars and altering its evolution. Researchers study ram pressure stripping to understand how galaxies interact with their environments and how this process influences their evolution. By observing galaxies undergoing ram pressure stripping, scientists can learn more about the impact of environmental factors on galaxy evolution and the mechanisms by which galaxies lose gas and ultimately change their properties.
