As a galaxy falls into a galaxy cluster, gravitational interactions with other galaxies can strangle it by preventing it from accreting more gas. For galaxies with massive dark matter halos , another preventive mechanism called “virial shock heating” may also prevent gas from becoming cool enough to form stars.
