Gemini Near Infrared Spectrograph Observations of a Red Star Forming Galaxy at z=2.225: Evidence for Shock-Ionization due to a Galactic Wind

P. G. van Dokkum, M. Kriek, B. Rodgers +2

Recent studies have shown that K-luminous galaxies at 2<z<2.5 have high Halpha line widths and high [NII]/Halpha ratios. If these lines arise from photo-ionization by massive stars…
