Using a similar but updated method to 3D-HST in the field environment, we stack the H{alpha} maps in bins of stellar mass, measure the half-light radius of the H{alpha} distribution, and compare it to the stellar continuum. The ratio of the H{alpha} to stellar continuum half-light radius, R[H{alpha}/C]=R_eff,H{alpha}_/R_eff,Cont_, is smaller in the clusters by (6+/-9)%, but statistically consistent within 1{sigma} uncertainties. A negligible difference in R[H{alpha}/C] with environment is surprising, given the higher quenched fractions in the clusters relative to the field. We postulate that the combination of high quenched fractions and no change in R[H{alpha}/C] with environment can be reconciled if environmental quenching proceeds rapidly. We investigate this hypothesis by performing similar analysis on the spectroscopically confirmed, recently quenched cluster galaxies. 87% have H{alpha} detections, with star formation rates 8+/-1 times lower than star-forming cluster galaxies of similar stellar mass. Importantly, these galaxies have an R[H{alpha}/C] that is (81+/-8)% smaller than coeval star- forming field galaxies at fixed stellar mass. This suggests the environmental quenching process occurred outside-in. We conclude that disk truncation due to ram pressure stripping is occurring in cluster galaxies at z~1, but more rapidly and/or efficiently than in z<~0.5 clusters, such that the effects on R[H{alpha}/C] become observable just after the cluster galaxy has recently quenched.2021ApJ...923..222Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/923/222CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/131/716 : Ha scale length in Virgo and field spirals (Koopmann+, 2006)J/ApJ/655/51 : HDFS IRAC observations of 2<z<3.5 galaxies (Wuyts+, 2007)J/ApJ/706/1364 : SINS survey of high-z galaxies (Forster Schreiber+, 2009)J/ApJ/701/1965 : Radial dust properties of SINGS gal.
