Methanol maser condensations in W 48
The methanol-line spectra in two maser condensations at velocities ~41 and ~45km/s in the star-forming region W 48 have been studied. Cone search capability for table... -
CO obs. of molecular clouds in the 3rd Gal. quadrant
We present the results of an unbiased 12CO/13CO/C18O (J=1-0) survey in a portion of the third Galactic quadrant (TGQ): 219.75{deg}<=l<=229.75{deg} and... -
Extension of HOPS out to 500pc (eHOPS). I. Aquila
We present a Spitzer/Herschel focused survey of the Aquila molecular clouds (d~436pc) as part of the eHOPS (extension of the Herschel orion protostar survey, or HOPS, Out to 500... -
34.8-50GHz obs. toward Orion KL
We have conducted a line survey toward Orion KL using the Q-band receiver of the Tianma 65m radio telescope (TMRT), covering 34.8-50GHz with a velocity resolution between 0.79... -
A CO survey of the entire northern sky
We present a very large extension of the Galactic plane CO survey of Dame+ (2001ApJ...547..792D) to the entire northern sky ({delta}>-17{deg}). The extension was carried out... -
Column density maps for MWISP ^13^CO mol. clouds
We have obtained column density maps for an unbiased sample of 120 molecular clouds in the third quadrant of the Milky Way midplane (b<=|5|{deg}) within the Galactic... -
High-velocity dispersion compact clouds in the CMZ
This study developed an automated identification procedure for compact clouds with broad velocity widths in the spectral-line data cubes of highly crowded regions. The procedure... -
NH3 obs. (~23.7GHz) of SCOPE dense objects
The Planck Catalogue of Galactic Cold Clumps provides an all-sky sample of potential star-forming regions based on the submillimeter emission of their dust content. Around 1000... -
Morphological classif. of MWISP ^12^CO mol. clouds
We attempt to visually classify the morphologies of 18190 molecular clouds, which are identified in the ^12^CO(1-0) spectral line data over ~450deg^2^ of the second Galactic... -
PHANGS-ALMA: arcsecond CO(2-1) imaging of galaxies
We present PHANGS-ALMA, the first survey to map CO J=2-1 line emission at ~1" ~100pc spatial resolution from a representative sample of 90 nearby (d<~20Mpc) galaxies that lie... -
Distances & color excesses of high gal. mol. clouds
Based on the accurate color excess E_GBP,GRP_ of more than 4 million stars and the E_NUV,GBP_ of more than 1 million stars from Paper I (Sun+, 2021ApJS..254...38S), the distance... -
Nobeyama mapping survey of SCUBA-2 cores
We present the results of on-the-fly mapping observations of 44 fields containing 107 SCUBA-2 cores in the emission lines of molecules N_2_H^+^, HC_3_N, and CCS at 82-94GHz... -
CO obs. of molecular clouds in the MW midplane
In this work, we study the properties of molecular clouds in the second quadrant of the Milky Way Midplane, from l=104.75{deg} to l=119.75{deg}, and b=-5.25{deg} to b=5.25{deg},... -
Planck Cold Clumps in the lambda Orionis complex. III.
Massive stars have a strong impact on their local environments. However, how stellar feedback regulates star formation is still under debate. In this context, we studied the... -
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)... -
OH and HI data in molecular clouds
We have conducted a OH 18cm survey toward 141 molecular clouds in various environments, including 33 optical dark clouds, 98 Planck Galactic cold clumps (PGCCs), and 10 Spitzer... -
Galactic interstellar ratio ^18^O/^17^O. I.
The interstellar oxygen isotopic ratio of ^18^O/^17^O can reflect the relative amount of the secular enrichment by ejecta from high-mass versus intermediate-mass stars. Previous... -
Nobeyama molecular line survey of SCUBA-2 cores
We present the results of a single-pointing survey of 207 dense cores embedded in Planck Galactic Cold Clumps distributed in five different environments ({lambda} Orionis, Orion... -
