We present a CO(3–2) survey of selected regions in the M31 disc as part of the JCMT large programme, HARP and SCUBA-2 High-Resolution Terahertz Andromeda Galaxy Survey (HASHTAG). The 12 CO(3–2) fields in this survey cover a total area of 60 arcmin2, spanning a deprojected radial range of 2–14 kpc across the M31 disc. Combining these observations with existing IRAM 30 m CO(1–0) observations and JCMT CO(3–2) maps of the nuclear region of M31, as well as dust temperature and star formation rate… 
A Herschel mapping of [C ii], [O i] and [O iii] lines from the circumnuclear region of M31
The circumnuclear region of M31, consisting of multiphase interstellar media, provides a close-up view of the interaction of the central supermassive black hole and surrounding materials.
The HASHTAG Project: The First Submillimeter Images of the Andromeda Galaxy from the Ground
Observing nearby galaxies with submillimeter telescopes on the ground has two major challenges. First, the brightness is significantly reduced at long submillimeter wavelengths compared to the
A Decade of SCUBA-2: A Comprehensive Guide to Calibrating 450 μm and 850 μm Continuum Data at the JCMT
The Submillimetre Common User Bolometer Array 2 (SCUBA-2) is the James Clerk Maxwell Telescope’s continuum imager, operating simultaneously at 450 and 850 μm. SCUBA-2 was commissioned in 2009–2011,


A CO J = 3–2 map of M51 with HARP-B: radial properties of the spiral structure
We present the first complete CO J=3-2 map of the nearby grand-design spiral galaxy M51 (NGC 5194), at a spatial resolution of ~600 pc, obtained with the HARP-B instrument on the James Clerk Maxwell
ASTE CO (3-2) Observations of the Barred Spiral Galaxy M 83: I. Correlation between CO (3-2)/ CO (1-0) Ratios and Star Formation Efficiencies
We present CO (J = 3–2) emission observations with the ASTE toward the 50 50 (or 6.6 kpc 6.6 kpc at the distance D = 4.5 Mpc) region of the nearby barred spiral galaxy M 83. We successfully resolved
A CO J = 3–2 Survey of the Galactic Center
We have surveyed the central molecular zone (CMZ) of our Galaxy in the CO J=3-2 line with the Atacama Submillimeter-wave Telescope Experiment (ASTE). Molecular gas in the Galactic center shows high
A multi‐transition CO and 13CO survey of the Galactic Plane
A survey of the Galactic Plane in the (2→1) and (3→2) rotational transitions of CO and 13CO has been carried out using the 10 m telescope of the Caltech Submillimeter Observatory (CSO). These data,
We present high-resolution CO J = 3-2 maps of the Galactic center region, taken with the ASTE 10 m telescope. We have collected approximately 30,000 spectra with a 34'' grid spacing. The mapping area
We present The H I Nearby Galaxy Survey (THINGS), a high spectral (≤5.2 km s–1) and spatial (~6'') resolution survey of H I emission in 34 nearby galaxies obtained using the NRAO Very Large Array
Two selected regions in the molecular gas spiral arms in M51 were mapped with the Owens Valley Radio Observatory (OVRO) mm-interferometer in the (CO)-C-12(2-1), (CO)-C-13(1-0), (CO)-O-18(1-0),
Star Formation in NGC 5194 (M51a). II. The Spatially Resolved Star Formation Law
We have studied the relationship between the star formation rate (SFR), surface density, and gas surface density in the spiral galaxy M51a (NGC 5194), using multiwavelength data obtained as part of
CO(J=3-2) On-the-fly Mapping of the Nearby Spiral Galaxies NGC 628 and NGC 7793: Spatially-resolved CO(J=3-2) Star-formation Law
We present the results of CO(J=3-2) on-the-fly mappings of two nearby non-barred spiral galaxies NGC 628 and NGC 7793 with the Atacama Submillimeter Telescope Experiment at an effective angular
