Star-forming Dense Cloud Cores in the TeV Gamma-ray SNR RX J1713.7-3946
(2010)
RX J1713.7–3946 is one of the TeV γ-ray supernova remnants (SNRs) emitting synchrotron X-rays. The SNR is associated with molecular gas located at ~1 kpc. We made new molecular observations toward the dense cloud cores, ...
A model for the onset of self gravitation and star formation in molecular gas governed by galactic forces. I. cloud scale gas motions
(IOP Publishing Ltd, 2018)
Modern extragalactic molecular gas surveys now reach the scales of star-forming giant molecular clouds (GMCs; 20-50 pc). Systematic variations in GMC properties with galaxy environment imply that clouds are not universally ...
A Model for the Onset of Self-gravitation and Star Formation in Molecular Gas Governed by Galactic Forces. I. Cloud-scale Gas Motions
(Institute of Physics Publishing, 2018)
Modern extragalactic molecular gas surveys now reach the scales of star-forming giant molecular clouds (GMCs;
20–50 pc). Systematic variations in GMC properties with galaxy environment imply that clouds are not ...
Ubiquitous velocity fluctuations throughout the molecular interstellar medium
(Nature, 2020)
Statistical analysis of velocity fluctuations in the interstellar medium (ISM) of the Milky Way and NGC 4321 show that the motion of molecular gas over scales ranging from 0.1 to 1,000 pc is similar, and consistent with ...
The "Nessie" Nebula: Cluster Formation in a Filamentary Infrared Dark Cloud
(2010)
The "Nessie" Nebula is a filamentary infrared dark cloud (IRDC) with a large aspect ratio of over 150:1 (1.5 degrees x 0.01 degrees, or 80 pc x 0.5 pc at a kinematic distance of 3.1 kpc). Maps of HNC (1-0) emission, a ...
Deuteration in infrared dark clouds
(Oxford University Press, 2016)
Much of the dense gas in molecular clouds has a filamentary structure but the detailed structure and evolution of this gas is poorly known. We have observed 54 cores in infrared dark clouds (IRDCs) using N2H+ (1-0) and ...
Dendrogram Analysis of Large-Area CARMA Images in Perseus: the Dense Gas in NGC 1333, Barnard 1, and L1451
(American Astronomical Society, 2014)
We present spectral line maps of the dense gas across 400 square arcminutes of the Perseus Molecular Cloud, focused on NGC 1333, Barnard 1, and L1451. We constructed these maps as part of the CARMA Large Area Star-formation ...
Molecular clumps towards compact H II regions
(Wiley Blackwell Publishing, Inc, 2019-08)
To better understand how the H II regions can affect their surrounding molecular clouds we have studied the molecular distribution towards three compact H II regions associated with IRAS sources (08140-3559, 09014-4736, ...
