Spatially resolve chemodynamics of Green Pea galaxies

Green Pea (GP) galaxies are the best local analogues of young high-redshift galaxies and ideal laboratories to study galaxy formation, reionization and feedback under extreme physical conditions. Complex emission line profiles for 6 GPs were observed using high-resolution spectroscopy at the WHT sho...
