We investigate the stellar populations and molecular gas properties of a star- forming region within the dwarf irregular (dIrr) galaxy Wolf-Lundmark-Mellote (WLM)....

We investigated the properties of the interstellar medium (ISM) at giant molecular cloud (GMC) scales (~100 pc) in a sample of 27 nearby luminous infrared galaxies (LIRGs)...

We report the spatial distribution and physical characteristics of molecular clouds in the G24 region, which is located near the intersection of the Milky Way's Galactic bar...

This paper uses observations of dusty debris discs, including a growing number of gas detections in these systems, to test our understanding of the origin and evolution of this...

CO, ^13^CO, and C^18^O J=3-2 observations are presented of the Ophiuchus molecular cloud. The ^13^CO and C^18^O emission is dominated by the Oph A clump, and the Oph B1, B2, C,...

An analysis of 44GHz Very Large Array observations of the z=1.574 radio-loud quasar 3C 318 has revealed emission from the redshifted J=1-->0 transition of the CO molecule and...

We have carried out a survey for CO J=1-0 and J=2-1 emission in the 260 early-type galaxies of the volume-limited ATLAS3D sample, with the goal of connecting their star...

The relationships between atomic and molecular hydrogen and dust of various sizes in extragalactic star-forming regions are considered, based on observational data from the...

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...

The mass distribution of dense cores is a potential key to understanding the process of star formation. Applying dendrogram analysis to the CARMA-NRO Orion C^18^O (J=1-0) data,...

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...

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...

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...

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...

We present the Virgo Environment Traced in CO (VERTICO) survey, a new effort to map ^12^CO(2-1), ^13^CO(2-1), and C^18^O(2-1) in 51 Virgo Cluster galaxies with the Atacama...

The FU Orionis-type objects (FUors) are low-mass pre-main-sequence stars undergoing a temporary but significant increase of mass accretion rate from the circumstellar disk onto...

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},...

We present the host-galaxy molecular gas properties of a sample of 213 nearby (0.01<z<0.05) hard-X-ray-selected active galactic nucleus (AGN) galaxies, drawn from the...

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)...

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...
