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...

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...

Polycyclic aromatic hydrocarbons (PAHs) are of great astrochemical and astrobiological interest due to their potential to form prebiotic molecules. We analyse the 7.7 and...

We present high spatial resolution (~= 12 pc) Atacama Large Millimeter/submillimeter Array 12CO(J = 3-2) observations of the nearby lenticular galaxy NGC 4429. We identify 217...

Deuterated methanol is one of the most robust windows astrochemists have on the individual chemical reactions forming deuterium-bearing molecules and the physicochemical history...

We study the spatially resolved star formation history (SFH) and molecular gas distribution of 58 nearby galaxies, using integral field spectroscopy from the CALIFA survey and...

We measure empirical relationships between the local star formation rate (SFR) and properties of the star-forming molecular gas on 1.5kpc scales across 80 nearby galaxies. These...

The paper suggests the presence of the carbon chain C_5_ molecule in translucent, interstellar HI clouds. This species, the only five atom interstellar molecule, observable in...

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...

We present a comparative study of the near-infrared (NIR) H_2_ line emission from five regions near hot young stars: Sharpless 140, NGC2023, IC63, the Horsehead Nebula, and the...

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 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,...

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...

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...

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...

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...

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...

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...

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...

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...
