Molecular clouds from NOEMA CO(1-0) obs. in M82
We present a 154 pointing IRAM NOEMA mosaic of the CO(1-0) line emission in and around the nearby starburst galaxy M82. The observations, complemented by zero-spacing... -
SOFIA CII and NII obs. of M101 and NGC6946
The [CII] fine-structure transition at 158{mu}m is frequently the brightest far-infrared line in galaxies. Due to its low ionization potential, C+ can trace the ionized, atomic,... -
FUSE survey of H_2_ in the Galactic disk
We report results from a Far Ultraviolet Spectrographic Explorer (FUSE) survey of interstellar molecular hydrogen (H_2_) in the Galactic disk toward 139 O-type and early B-type... -
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... -
The TW Hya Rosetta Stone Project. III.
The thermal structure of protoplanetary disks is a fundamental characteristic of the system that has wide-reaching effects on disk evolution and planet formation. In this study,... -
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... -
Sulfur isotopes in SFR with 12m ARO and 30m IRAM
We present observations of 12C32S, 12C34S, 13C32S, and 12C33S J=2-1 lines toward a large sample of massive star-forming regions by using the Arizona Radio Observatory 12m... -
Molecular ISM in nearby star-forming galaxies
We compare the observed turbulent pressure in molecular gas, P_turb_, to the required pressure for the interstellar gas to stay in equilibrium in the gravitational potential of... -
Astrochemical study along M83 circumnuclear ring
We report an astrochemical study on the evolution of interstellar molecular clouds and consequent star formation in the center of the barred spiral galaxy M83. We used the... -
Dark molecular gas in the Galaxy II. Perseus arm
We report the results from a new, highly sensitive ({Delta}T_mb_~3mK) survey for thermal OH emission at 1665 and 1667MHz over a dense, 9x9pix grid covering a 1{deg}x1{deg} patch... -
Nobeyama 45m Cygnus-X CO. II. C180 clumps
We report the statistical physical properties of the C^18^O(J=1-0) clumps present in a prominent cluster-forming region, Cygnus X, using the data set obtained by the Nobeyama... -
ALMA obs. of star-forming regions toward NGC6334I
The relative column densities of the structural isomers methyl formate, glycolaldehyde, and acetic acid are derived for a dozen positions toward the massive star-forming regions... -
ALMA data for 5 luminous & ultraluminous IR gal.
A new analysis of high-resolution data from the Atacama Large Millimeter/submillimeter Array for five luminous or ultraluminous infrared galaxies gives a slope for the... -
Observed transitions of CH_3_OH and CH_3_CHO
IRAM 30m Observations toward eight protostellar outflow sources were taken in the 96-176GHz range. Transitions of CH_3_OH and CH_3_CHO were detected in seven of them. The... -
EMPIRE: IRAM 30m dense gas survey
We present EMPIRE, an IRAM 30m large program that mapped {lambda}=3-4mm dense gas tracers at ~1-2kpc resolution across the whole star-forming disk of nine nearby massive spiral... -
ALMA obs. of ethyl formate toward Orion KL
Orion KL is one of the prime templates of astrochemical and prebiotic chemical studies. We wish to explore more organic molecules with increasing complexity in this region. In... -
CO molecular clumps in Henize 2-10 dwarf galaxy
We present Atacama Large Millimeter/Submillimeter Array CO(3-2) observations at 0.3" resolution of He 2-10, a starburst dwarf galaxy and possible high-z galaxy analog. The warm... -
First detection of HCOOH in TW Hya disk with ALMA
The formation of asteroids, comets, and planets occurs in the interior of protoplanetary disks during the early phase of star formation. Consequently, the chemical composition... -
Cloud-scale molecular gas properties in 15 galaxies
We measure the velocity dispersion, {sigma}, and surface density, {Sigma}, of the molecular gas in nearby galaxies from CO spectral line cubes with spatial resolution 45-120pc,... -
