HST Imaging of Star-forming Clumps in Six GASP Ram-pressure-stripped Galaxies

Exploiting broad- and narrow-band images of the \textit{Hubble Space Telescope} from near-UV to I-band restframe, we study star-forming clumps six galaxies GASP sample undergoing strong ram-pressure stripping (RPS). Clumps are detected in H$\alpha$ near-UV, tracing star formation on different timescales. We consider located galaxy disks, stripped tails those formed gas but still close disk, called extraplanar. detect 2406 H$\alpha$-selected (1708 375 extraplanar regions, 323 tails) 3750 UV-selected (2026 disk clumps, 825 899 tail clumps). Only $\sim15\%$ spatially resolved, meaning that most smaller than $\sim 140$ pc. luminosity size distribution functions (LDFs SDFs, respectively) luminosity-size relation. The average LDF slope is $1.79\pm 0.09$, while SDF $3.1\pm 0.5$. Results suggest be turbulence driven scale-free, as main-sequence galaxies. All whether they disks or tails, have an enhanced at a given size, compared Indeed, their closer starburst galaxies, indicating ram pressure able enhance luminosity. No striking differences found among suggesting environments which embedded play minor role influencing formation.
