TIMES II: Investigating the Relation Between Turbulence and Star-forming Environments in Molecular Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Neal J. Evans +14
We investigate the effect of star formation on turbulence in the Orion A and Ophiuchus clouds using principal component analysis (PCA). We measure the properties of turbulence by a…
Which Molecular Cloud Structures Are Bound?
Neal J. Evans, Mark Heyer. Marc-Antoine Miville-Deschênes, Quang Nguyen-Luong. Manuel Merello
We analyze surveys of molecular cloud structures defined by tracers ranging from CO through CO to dust emission together with NH data. The mean value…
The filamentary structures in the CO emission toward the Milky Way disk
J. D. Soler, H. Beuther, J. Syed +11
We present a statistical study of the filamentary structure orientation in the CO emission observations obtained in the Milky Way Imaging Scroll Painting (MWISP) survey in the rang…
TIMES I: a Systematic Observation in Multiple Molecular Lines Toward the Orion A and Ophiuchus Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Yunhee Choi +16
We have used the Taeduk Radio Astronomy Observatory to observe the Orion A and Ophiuchus clouds in the 10 lines of CO, CO, HCN, HCO, and NH and the…
The Single-Cloud Star Formation Relation
Riwaj Pokhrel, Robert A. Gutermuth, Mark R. Krumholz +10
One of the most important and well-established empirical results in astronomy is the Kennicutt-Schmidt (KS) relation between the density of interstellar gas and the rate at which t…
