Evolution of H$\alpha$ Equivalent Widths from $z\sim 0.4-2.2$: implications for star formation and legacy surveys with Roman and Euclid

Ali Ahmad Khostovan, Sangeeta Malhotra, James E. Rhoads +5

We investigate the `intrinsic' H$\alpha$ EW distributions of $z\sim 0.4-2.2$ narrowband-selected H$\alpha$ samples from HiZELS and DAWN using a forward modeling approach. We find an EW -…
