  • The ACT-DR5 MCMF cluster catalog

    Galaxy clusters are useful cosmological probes and interesting astrophysical laboratories. As the cluster samples continue to grow n size, a deeper understanding of the sample...
  • Comets C/2021 A1 and C/2022 E3 (ZTF) spectra

    We present the results of a molecular survey of long period comets C/2021 A1 (Leonard) and C/2022 E3 (ZTF). Comet C/2021 A1 was observed with the Institut de radioastronomie...
  • C/2014 Q2 (Lovejoy) spectra

    The presence of numerous complex organic molecules (COMs; defined as those containing 6 or more atoms) around protostars shows that star formation is accompanied by an increase...
  • SPT-SZ MCMF catalog

    We present an extension to a Sunyaev-Zel'dovich Effect (SZE) selected cluster catalogue based on observations from the South Pole Telescope (SPT); this catalogue extends to...
  • RASS-MCMF catalog

    We present the RASS-MCMF catalogue of 8449 X-ray selected galaxy clusters over 25000deg^2^ of extragalactic sky. The accumulation of deep multiband optical imaging data, the...
  • ATOMS Paper III, massive star-forming regions

    We have identified 453 compact dense cores in 3 mm continuum emission maps in the ALMA Three-millimetre Observations of Massive Star-forming regions survey, and compiled three...
  • The Alma catalogue of OB stars - II.

    We cross-match the Alma catalogue of OB stars with Gaia DR2 astrometry and photometry as a first step towards producing a clean sample of massive stars in the solar...
  • SSEDIGISM-ATLASGAL in Galactic disc

    By combining two surveys covering a large fraction of the molecular material in the Galactic disc, we investigate the role spiral arms play in the star formation process. We...
  • The SEDIGISM survey: molecular clouds

    We use the ^13^CO(2-1) emission from the SEDIGISM (Structure, Excitation, and Dynamics of the Inner Galactic InterStellar Medium) high-resolution spectral-line survey of the...
  • Faraday rotation of Northern hemisphere pulsars

    Using commissioning data from the first year of operation of the Canadian Hydrogen Intensity Mapping Experiment's (CHIME) Pulsar backend system, we conduct a systematic analysis...
  • HI angular momentum on late-type galaxies

    We use high-resolution HI data from the Westerbork HI Survey of Spiral and Irregular Galaxies (WHISP) to study the HI and angular momentum properties of a sample of 114...
  • ALMA polarimetric follow-up of PACO sources

    We present Atacama Large Millimetre/submillimiter Array (ALMA) high sensitivity ({sigma}P~0.4mJy) polarimetric observations at 97.5GHz (Band 3) of a complete sample of 32...
  • Arecibo polarimetric single-pulse survey

    We report on an Arecibo 4.5-GHz polarimetric single-pulse survey of the brightest pulsars at high frequency within its sky. The high-frequency profiles are accompanied by a...
  • Infall and outflow on massive star-forming regions

    A total of 188 high-mass outflows have been identified from a sample of 694 clumps from the Millimetre Astronomy Legacy Team 90GHz survey, representing a detection rate of...
  • 2MASS bright galaxies HI ZoA survey

    To complement the 2MASS Redshift Survey (2MRS) and the 2MASS Tully-Fisher survey (2MTF) a search for 21cm HI line emission of 2MASS bright galaxy candidates has been pursued...
  • TMRT Ka-band (26.1-35GHz) obs. of Orion-KL

    We conducted a Ka-band (26.1-35GHz) line survey toward Orion KL using the TianMa 65m Radio Telescope (TMRT). It is the first blind line survey in the Ka band and achieves a...
  • IRAM 3mm, 2mm & 1.3mm obs. of star-forming regions

    We carried out a spectral line survey of CH3OH toward a large sample of 175 high-mass star-forming regions in the 3mm, 2mm, and 1.3mm bands with the Institut de Radioastronomie...
  • NH_3_ transitions detections toward W51 IRS2

    A four-epoch monitoring program spanning ~three months (from 2020-January-8 to April-7) for ammonia, water, and methanol transitions toward the high-mass star-forming region W51...
  • 2mm and 3mm sp. of CRL 2688 protoplanetary nebula

    We present observations of the carbon-rich protoplanetary nebula CRL2688 made with the Institut de Radioastronomie Millimetrique 30m telescope in the 3 and 2mm bands. In total,...
  • Herschel SPIRE/FTS 194-671um survey of GOALS LIRGs

    We describe a Herschel Space Observatory 194-671{mu}m spectroscopic survey of a sample of 121 local luminous infrared galaxies and report the fluxes of the CO J to J-1...
