Ram-pressure stripping caught in action in a young cluster at $z = 2.51$

These represent the most distant confirmed cases of RPS, highlighting the critical role of environmental effects in gas removal at high redshifts, an often overlooked quenching pathway.
The elongated gas tails are produced by ram-pressure stripping rather than by outflows, tidal forces, or projection effects, based on the galaxies appearing isolated and lacking merger signatures (abstract).
ALMA observations reveal ram-pressure stripping in five galaxies at z=2.51, the most distant confirmed instances, indicating environmental gas removal in a protocluster.
