  • Faint companions around YSOs in TMC

    We have conducted near-infrared spectroscopy of 26 faint objects around young stellar objects in the Taurus molecular cloud. These objects were detected during a course of...
  • CO molecular clouds in Carina flare supershell

    We present a catalogue of ^12^CO(J=1-0) and ^13^CO(J=1-0) molecular clouds in the spatio-velocity range of the Carina Flare supershell, GSH287+04-17. The data cover a region of...
  • JHK photometry of low-mass stars in BRC 14

    We carried out a deep near-infrared survey of a bright-rimmed molecular cloud, BRC 14 (IC 1848A). The 10{sigma} limiting magnitude of the survey is 17.7mag at the K-band....
  • CO molecular clouds in southern Galactic Warp

    We made an unbiased search for molecular clouds in the Galactic Warp. This survey, covering an area of 56 square degrees at l=252{deg} to 266{deg} and b=-5{deg} to -1{deg},...
  • 13CO survey of Mon & CMa molecular clouds

    Through a large-scale 13^CO (J=1-0) survey toward a region in Monoceros and Canis Major, we have identified in total 115 clouds. Cone search capability for table...
  • Chandra observations of Monoceros R2

    We report on the results of the Chandra ACIS-I observation on the central region of the Monoceros R2 cloud (Mon R2), a high-mass star-forming region (SFR) at a distance of...
  • CO catalog of LMC molecular clouds

    From a ^12^CO (J=1-0) survey with the NANTEN telescope, we present a complete catalog of giant molecular clouds (GMCs) in the Large Magellanic Cloud. In total, 107 CO clouds...
  • CO molecular clouds in Lupus

    The Lupus star-forming region has been surveyed for molecular clouds in ^12^CO with the NANTEN radio telescope, and a cloud mass of 1.7x10^4^M_{sun} has been revealed. We were...
  • Molecular clouds in southern HII regions

    We have carried out extensive ^13^CO(J=1-0) observations toward 23 southern H II regions associated with bright-rimmed clouds. In total, 95 molecular clouds have been identified...
  • M120.1+3.0 molecular cloud CO observations

    We present large-scale (2{deg}x2{deg}) observations toward the molecular cloud M120.1+3.0, using ^12^CO, ^13^CO and C^18^O (J=1-0) data from the Purple Mountain Observatory...
  • Molecular Clumps & Cores with Infall Signatures

    The research of infall motion is a common means to study molecular cloud dynamics and the early process of star formation. Many works had been done in-depth research on infall....
  • Molecular clumps CO, HCO and HCN data

    Gravitational accretion accumulates the original mass. This process is crucial for us to understand the initial phases of star formation. Using the specific infall profiles in...
  • Cores detected at 1.3mm in W43-MM1

    Understanding the processes that determine the stellar initial mass function (IMF) is a critical unsolved problem, with profound implications for many areas of astrophysics. In...
  • High-mass star forming clumps from MALT90

    A total of 197 relatively isolated high-mass star-forming clumps were selected from the Millimeter Astronomy Legacy Team 90GHz (MALT90) survey data and their global chemical...
  • Deuterium in L1688 cold dense cores

    In this work, we study deuterium fractionation in four starless cores in the low-mass star-forming region L1688 in the Ophiuchus molecular cloud. We study how the deuterium...
  • Magnetic field of L1495/B211

    We present the stability analysis of two regions, OMC-3 and OMC-4, in the massive and long molecular cloud complex of Orion A. We obtained 214um HAWC+/SOFIA polarization data,...
  • Polarimetric study of LDN 1616 background stars

    The Lynds' Dark Nebula (LDN) 1615/1616 and CB 28 (hereafter L1616) together form a cometary globule located at an angular distance of about 8{deg} west of the Orion OB1...
  • ATOMS ALMA 3 mm VII SiO clumps with ACA

    To understand the nature of SiO emission, we conducted ACA observations of the SiO (2-1) lines toward 146 massive star-forming regions, as part of the ALMA Three-millimeter...
  • Molecular clouds study from 3D extinction maps

    We present a large catalogue of molecular clouds with accurate distance estimates in the Southern sky. Based on the three-dimensional dust extinction map and the best-fitting...
  • ATOMS IV Gas clumps properties and SFRs

    We report the detection of radio recombination line (RRL) H_40{alpha} towards 75 sources, with data obtained from ACA (Atacama Compact 7 m Array) observations in the ATOMS (ALMA...
