Variation of Dense Gas Mass–Luminosity Conversion Factor with Metallicity in the Milky Way

Variation of Dense Gas Mass–Luminosity Conversion Factor with Metallicity in the Milky Way

HCN and HCO ^+ are the most common dense gas tracers used both in the Milky Way and external galaxies. The luminosity of HCN and HCO ^+ J  = 1 → 0 lines are converted to a dense gas mass by the conversion factor, α _Q . Traditionally, this α _Q has been considered constant throughout the Galaxy and...
