ABSTRACT The Hubble Frontier Fields represent the opportunity to probe high-redshift evolution of main sequence star-forming galaxies lower masses than possible in blank fields thanks foreground lensing massive galaxy clusters. We use beagle SED-fitting code derive stellar masses, $\rm{{M_{\star }}}=\log ({\it M}/{\rm{M_{\odot }}})$, SFRs, $\rm{{\Psi }}=\log (\rm{{\psi }}/{\rm{M_{\odot }}}\, {\...
