In CGCG 007-025, high-resolution spectroscopy resolves a kinematically distinct, asymmetric HeII line and line ratios that imply fast radiative shocks at 250-300 km/s, and shows the claimed [FeX] coronal detection is a SiII line.

Shocks and complex chemodynamics in the metal-poor starburst galaxy CGCG 007-025 revealed through high-resolution echelle spectroscopy
In CGCG 007-025, high-resolution spectroscopy resolves a kinematically distinct, asymmetric HeII line and line ratios that imply fast radiative shocks at 250-300 km/s, and shows the claimed [FeX] coronal detection is a SiII line.
