  • N159 ^12^CO and ^13^CO (2-1) clumps

    The N159 star-forming region is one of the most massive giant molecular clouds (GMCs) in the Large Magellanic Cloud (LMC). We show the ^12^CO, ^13^CO, CS molecular gas lines...
  • ^12^CO and ^13^CO cores & clumps in LHA 120-N 55

    We present the molecular cloud properties of N55 in the Large Magellanic Cloud using ^12^CO(1-0) and ^13^CO(1-0) observations obtained with Atacama Large Millimeter Array. We...
  • mm point sources in the extended Sgr B2 cloud

    We report ALMA observations with resolution ~0.5" at 3mm of the extended Sgr B2 cloud in the Central Molecular Zone (CMZ). We detect 271 compact sources, most of which are...
  • Herschel nearby isolated low-mass clouds maps

    We present intensity-corrected Herschel maps at 100, 160, 250, 350, and 500{mu}m for 56 isolated low-mass clouds. We determine the zero-point corrections for Herschel...
  • Protoplanetary disk data in Cha I and Lupus

    In this paper, we investigate the relation between disk mass and mass accretion rate to constrain the mechanism of angular momentum transport in protoplanetary disks. We find a...
  • Virial analysis of the dense cores in Orion A

    We use data on gas temperature and velocity dispersion from the Green Bank Ammonia Survey and core masses and sizes from the James Clerk Maxwell Telescope Gould Belt Survey to...
  • Optical spectroscopy toward Orion B fields

    We present results from high-resolution optical spectra toward 66 young stars in the Orion B molecular cloud to study their kinematics and other properties. Observations of the...
  • Cloud decomposition & SFR measurements

    Galactic star formation scaling relations show increased scatter from kpc to sub-kpc scales. Investigating this scatter may hold important clues to how the star formation...
  • Molecular clouds with GLIMPSE/MIPSGAL data

    We study the star-formation (SF) law in 12 Galactic molecular clouds with ongoing high-mass star-formation (HMSF) activity, as traced by the presence of a bright IRAS source and...
  • CO large-field observations around l=150{deg}

    We present large-field (4.25x3.75deg^2^) mapping observations toward the Galactic region centered at l=150{deg},b=3.5{deg} in the J=1-0 emission line of CO isotopologues...
  • Deep NIR spectrum of the Orion Bar PDR

    We present a deep near-infrared spectrum of the Orion Bar Photodissociation Region (PDR) taken with the Immersion Grating INfrared Spectrometer (IGRINS) on the 2.7m telescope at...
  • The Taurus-Auriga ecosystem. I.

    The census of Taurus-Auriga has been assembled over seven decades and inherited the biases and incompleteness of the input studies. The unusual shape of its inferred initial...
  • IRDC G028.23-00.19 NIR polarimetry analysis

    The importance of the magnetic (B) field in the formation of infrared dark clouds (IRDCs) and massive stars is an ongoing topic of investigation. We studied the plane-of-sky B...
  • 218GHz obs. of embedded protostars in Ophiuchus

    We present APEX 218GHz observations of molecular emission in a complete sample of embedded protostars in the Ophiuchus star-forming region. To study the physical properties of...
  • Molecular clouds in the dwarf galaxy NGC6822

    We present the Atacama Large Millimeter/submillimeter Array survey of CO(2-1) emission from the 1/5 solar metallicity, Local Group dwarf galaxy NGC 6822. We achieve high...
  • Milky Way molecular clouds from ^12^CO

    This study presents a catalog of 8107 molecular clouds that covers the entire Galactic plane and includes 98% of the ^12^CO emission observed within b+/-5^{deg}^. The catalog...
  • Gould's Belt Distances Survey (GOBELINS). II. OMC

    We present the results of the Gould's Belt Distances Survey of young star-forming regions toward the Orion Molecular Cloud Complex. We detected 36 young stellar objects (YSOs)...
  • Infall/expansion velocities in 3 dense cores

    Although surveys of infall motions in dense cores have been carried out for years, few surveys have focused on mapping infall across cores using multiple spectral-line...
  • Star forming cloud-giant molecular cloud complexes

    Star formation on galactic scales is known to be a slow process, but whether it is slow on smaller scales is uncertain. We cross-correlate 5469 giant molecular clouds (GMCs)...
  • The magnetic field of L1544. I. NIR data

    The magnetic field (B-field) of the starless dark cloud L1544 has been studied using near-infrared (NIR) background starlight polarimetry (BSP) and archival data in order to...
