It's a process called ram pressure stripping because it strips that material out of the disk to form the tentacle shape.
The tentacles of jellyfish galaxies are produced in galaxy clusters by a process called ram pressure stripping.
Finally, the fill factor of the mix acts very similar to the way ram pressure acts; that is, a higher fill factor will yield a faster mix (to a point), and the lower the fill, the slower the mix time.
Since its galaxies orbit at a slower pace and its intracluster medium is less dense, its ram pressure is consequently lower.
Several loss mechanisms are possible, including ram-pressure stripping by intracluster gas, gravitational interactions with other galaxies within the cluster, and gas outflows due to simultaneous supernova explosions triggered by the ram pressure or gravitational encounters.
Ram pressure has strung this gas away from its home in the spiral galaxy and out over intergalactic space.
Along with tidal stretching, the cloud also experiences resistance in the form of ram pressure as it tries to plow through the hot interstellar gas that already fills the space around Sgr A*.

The meteor burns and glows because of ram pressure not friction.
On older-style systems, the cutting depth was typically controlled by adjusting the shield advancing ram pressure.
The galaxy's stars can withstand this impact, known as ram pressure, but its fluffy gas clouds are easily torn from their gravitational moorings and blown outward.
