cds-question@unistra.frgalaxiesinfrared-sourcesvisible-astronomygalaxy-classification-systemsredshiftedRam pressure stripping is one of the most efficient mechanisms able to affect the gas reservoir in cluster galaxies, and in the last decades many studies have characterized the properties of stripped galaxies. A definite census of the importance of this process in local clusters is still missing, though. Here, we characterize the fraction of galaxies showing signs of stripping at optical wavelengths, using the data of 66 clusters from the WINGS and OMEGAWINGS surveys. We focus on the infalling galaxy population, and hence only consider blue, bright (B<18.2), late-type, spectroscopically confirmed cluster members within two virial radii. In addition to "traditional" stripping candidates (SC)-i.e., galaxies showing unilateral debris and tails- we also consider unwinding galaxies (UG) as potentially stripped galaxies. Recent work has indeed unveiled a connection between unwinding features and ram pressure stripping, and even though only integral field studies can inform on how often these features are indeed due to ram pressure, it is important to include them in the global census. We performed a visual inspection of B-band images, and here we release a catalog of 143 UG. SC and UG each represent ~15%-20% of the inspected sample. If we make the assumption that they both are undergoing ram pressure stripping, we can conclude that, at any given time in the low-z universe, about 35% of the infalling cluster population show signs of stripping in their morphology at optical wavelengths. These fractions depend on color, mass, and morphology, and little on clustercentric distance. Making some rough assumptions regarding the duration of the tail visibility and the time that cluster galaxies can maintain blue colors, we infer that almost all bright blue late-type cluster galaxies undergo a stripping phase during their life, boosting the importance of ram pressure stripping in cluster galaxy evolution.2022ApJ...927...91Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/927/91CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/281/799 : XBACs, the sample (Ebeling+, 1996)J/A+AS/122/399 : K and evolutionary corrections (Poggianti, 1997)J/MNRAS/301/881 : The ROSAT brightest cluster sample - I.
