We present measurements of star formation rates (SFRs) for dwarf galaxies (M* ∼ 108.5 M⊙ M⊙) at z ∼ 1 using near-infrared slitless spectroscopy from the Hubble Space Telescope (HST) by targeting and measuring the luminosity of the Hα emission line. Our sample is derived from the Redshift One LDSS3 Emission Line Survey (ROLES), which used [O ii]λ3727 as a tracer of star formation to target very low stellar masses down to very low SFRs (∼0.1 M⊙ M⊙ yr−1) at this epoch. Dust corrections are…
