CO survey of the CMa OB1 complex
Using the Purple Mountain Observatory 13.7m millimeter telescope at Delingha in China, we have conducted a large-scale simultaneous survey of ^12^CO, ^13^CO, and C^18^O (J=1-0)... -
CO outflow cand. toward W3/4/5 complex. II.
To date, few studies have focused on protostellar outflow feedback at scales larger than several parsecs. To address this paucity of research, we investigate the effects of... -
CO outflow candidates toward W3/4/5 complex
Using the Purple Mountain Observatory Delingha 13.7m telescope, we conducted a large-scale ^12^CO(J=1->0) outflow survey (over ~110deg^2^) toward the W3/4/5 complex and its... -
CO and 850um obs. of Planck Galactic cold clumps
In order to understand the initial conditions and early evolution of star formation in a wide range of Galactic environments, we carried out an investigation of 64 Planck... -
Massive outflows associated with ATLASGAL clumps
We have undertaken the largest survey for outflows within the Galactic plane using simultaneously observed ^13^CO and C^18^O data. Out of a total of 919 ATLASGAL clumps, 328... -
CO obs. toward Gem OB1 molecular cloud complex. II.
We present a large-scale survey of CO outflows in the Gem OB1 molecular cloud complex and its surroundings, using the Purple Mountain Observatory Delingha 13.7m telescope. A... -
SCUBA-2 Galactic Center compact source catalog
We present new JCMT SCUBA-2 observations of the Galactic Center region from 355{deg}<l<5{deg} and b<+/-1{deg}, covering 10x2 square degrees along the Galactic Plane to... -
xCOLD GASS catalog
We introduce xCOLD GASS, a legacy survey providing a census of molecular gas in the local universe. Building on the original COLD GASS survey, we present here the full sample of... -
CO obs. of MCs in the Extreme Outer Galaxy region
We present the results of an unbiased CO survey in the Galactic range of 34.75{deg}<=l<=45.25{deg} and -5.25{deg}<=b<=5.25{deg}, and the velocity range beyond the... -
CO survey of W51 molecular cloud
We present 38" resolution maps of the CO and ^13^COJ=2-1 lines in the molecular clouds toward the HII region complex W51. The maps cover a 1.25x1{deg} section of the galactic... -
Molecular clouds and clumps in the GRS
The Boston University-Five College Radio Astronomy Observatory (BU-FCRAO) Galactic Ring Survey (GRS) of ^13^CO J=1->0 emission covers Galactic longitudes 18<l<55.7{deg}... -
CO emission in the Taffy galaxies. I. ALMA obs.
We present Atacama Large Millimeter/submillimeter Array observations at a spatial resolution of 0.2" (60pc) of CO emission from the Taffy galaxies (UGC 12914/5). The... -
Low-J CO line ratios for 152 CO map pairs
We measure the low-J CO line ratios R_21_=CO(2-1)/CO(1-0), R_32_=CO(3-2)/CO(2-1), and R_31_=CO(3-2)/CO(1-0) using whole-disk CO maps of nearby galaxies. We draw CO(2-1) from... -
Molecular cloud distances from CO & Gaia data
The principle of the background-eliminated extinction-parallax (BEEP) method is examining the extinction difference between on- and off-cloud regions to reveal the extinction... -
C^18^O dense cores identified in the CMC region
We present the survey of ^12^CO/^13^CO/C^18^O (J=1-0) toward the California molecular cloud (CMC) within the region of 161.75{deg}<=l<=167.75{deg},... -
ALMA survey of protoplanetary disks in Lynds 1641
We present ALMA observations of 101 protoplanetary disks within the star-forming region Lynds 1641 in the Orion Molecular Cloud A. Our observations include 1.33 mm continuum... -
Molecular gas distribution from MWISP CO survey
We use the ~370deg^2^ data from the MWISP CO survey to study the vertical distribution of the molecular clouds (MCs) toward the tangent points in the region of... -
A galaxy sample with CO(2-1) and CO(5-4) detections
We study the carbon monoxide (CO) excitation, mean molecular gas density, and interstellar radiation field (ISRF) intensity in a comprehensive sample of 76 galaxies from local... -
Molecular gas properties of 70 PHANGS-ALMA galaxies
Using the PHANGS-ALMA CO(2-1) survey, we characterize molecular gas properties on ~100pc scales across 102,778 independent sightlines in 70 nearby galaxies. This yields the best... -
Cold & molecular clumps and YSOs within G15.684-0.29
The bubble G15.684-0.29 has a radius of 15.7pc. Its large size indicates that it may have enough time to trigger star formation. We identify 39 dense cold clumps around the...
