Enhanced Star Formation Activity of Extreme Jellyfish Galaxies in Massive Clusters and the Role of Ram Pressure Stripping

Jellyfish galaxies are an excellent tool to investigate the short-term effects of ram pressure stripping (RPS) on star formation in cluster environments. It has been thought that activity jellyfish may depend host properties, but previous studies have not yet found a clear correlation. In this study, we estimate \Ha-based rates (SFRs) five massive clusters ($\sigma_{v, {\rm cl}}\gtrsim1000~{\rm km~s^{-1}}$) at $z\sim0.3-0.4$ using Gemini GMOS/IFU observations explore relationship. Combining our results with those literature, find shows positive correlation their velocity dispersion as proxy mass and dynamical states. We divide galaxy sample into two groups strong weak RPS signatures morphological class. phase-space diagram, features show higher SFR stronger central concentration than features. excess relative main sequence (starburstiness; $R_{\rm SB}={\rm SFR/SFR_{MS}}(z)$) density surrounding intracluster medium (ICM) scaling relations dispersion. As result, starburstiness clearly exhibits correlations dispersion, ICM density, strength pressure. This relation between depends properties
