Description
Understanding the distribution of molecular hydrogen (H₂) is essential for studying star formation in galaxies. However, direct observations of H₂ are difficult. Carbon species such as carbon monoxide (CO) and ionized carbon (C⁺) might be used as good tracers of molecular hydrogen, as their formation is closely related to the presence of H₂.
In this study, we perform high-resolution galaxy simulations using the GIZMO code, and conduct post-processing to calculate the abundance and emission of C⁺. We aim to investigate how well the tracer correlates with H₂ and star formation, especially in low-metallicity environment. This work will help to improve our understanding of molecular gas tracer and its connection to star formation.
