The Neon Gap: Probing Ionization with Dwarf Galaxies at z ∼ 1

We present measurements of [Ne iii ] λ 3869 emission in z ∼ 1 low-mass galaxies taken from the Keck/DEIMOS spectroscopic surveys HALO7D and DEEPwinds. We identify 167 individual galaxies with significant [Ne iii ] emission lines, including 112 “dwarf” galaxies with $\mathrm{log}({M}_{\star }/{M}_{\o...
