Monthly notices of the Royal Astronomical Society, 533(1), 341-359. https://doi.org/10.1093/mnras/stae1784

Ram pressure stripping is perhaps the most efficient mechanism for removing gas and quenching galaxies in dense environments, as they move through the intergalactic medium. Extreme examples of on-going ram pressure stripping are known as jellyfish ga...
