Constraints on the Lyman Continuum Escape from Low-mass Lensed Galaxies at 1.3 $\leq$ z $\leq$ 3.0

Understand

Low-mass galaxies can significantly contribute to reionization due to their potentially high Lyman continuum (LyC) escape fraction and relatively high space density.

• We present a constraint on the LyC escape fraction from low-mass galaxies at z = 1.3 - 3.0.
• We obtained rest-frame UV continuum imaging with the ACS/SBC and the WFC3/UVIS from the Hubble Space Telescope for eight strongly-lensed galaxies that were identified in the Sloan Giant Arc Survey (SGAS) and the Cluster Lensing And Supernova survey with Hubble (CLASH).
• The targeted galaxies were selected to be spectroscopically confirmed, highly magnified, and blue in their UV spectral shapes ($\beta<-1.7$).
