A deep dive into NGC604 with Gemini/NIRI imaging

The giant HII region NGC 604 constitutes a complex and rich population to study in detail many aspects of massive star formation, such as their environments and physical conditions, the evolutionary processes involved, the initial mass function for massive stars and starformation rates, among many o...
