Molecular Gas Content of HI Monsters and Implications to Cold Gas Content Evolution in Galaxies
Cheoljong Lee, Aeree Chung, Min S. Yun +3
We present 12CO (J=1-0) observations of a sample of local galaxies (0.04<z<0.08) with a large neutral hydrogen reservoir, or "HI monsters". The data were obtained using the Redshif…
The Parsec-Scale Relationship Between I_CO and A_V in Local Molecular Clouds
Cheoljong Lee, Adam K. Leroy, Alberto D. Bolatto +4
We measure the parsec-scale relationship between integrated CO intensity (I_CO) and visual extinction (A_V) in 24 local molecular clouds using maps of CO emission and dust optical…
Clumping and the Interpretation of kpc-Scale Maps of the Interstellar Medium: Smooth HI and Clumpy, Variable H2 Surface Density
Adam K. Leroy, Cheoljong Lee, Andreas Schruba +6
Many recent models consider the structure of individual interstellar medium (ISM) clouds as a way to explain observations of large parts of galaxies. To compare such models to obse…
The Relationship between CO Emission and Visual Extinction Traced by Dust Emission in the Magellanic Clouds
Cheoljong Lee, Adam K. Leroy, Scott Schnee +4
To test the theoretical understanding that finding bright CO emission depends primarily on dust shielding, we investigate the relationship between CO emission () and th…
