  • Star formation properties of LSBGs and SFs

    We analyzed the star formation surface density ({SIGMA}SFR) between the global and HII regions in a sample of 69 low surface brightness galaxies (LSBGs) and 68 star-forming (SF)...
  • Massive stars in 30 Dor

    The 30 Doradus star-forming region in the Large Magellanic Cloud is a nearby analog of large star-formation events in the distant universe. We determined the recent formation...
  • NIR-FIR phot. of YSOs in 2 UC HII regions

    Ultra-compact H II (UC HII) regions are an important phase in the formation and early evolution of massive stars and a key component of the interstellar medium (ISM). The main...
  • High-mass star formation evolutionary trends

    ATLASGAL is an 870um dust survey of 420deg^2^ the inner Galactic plane and has been used to identify ~10000 dense molecular clumps. Dedicated follow-up observations and...
  • Star clusters study in PHANGS-HST galaxies

    Using PHANGS-HST NUV-U-B-V-I imaging of 17 nearby spiral galaxies, we study samples of star clusters and stellar associations, visually selected to be bright and relatively...
  • Hydra I cluster study with H I emission

    We present results from our analysis of the Hydra I cluster observed in neutral atomic hydrogen (H I) as part of the Widefield ASKAP L-band Legacy All-sky Blind Survey...
  • High-mass star forming clumps from MALT90

    A total of 197 relatively isolated high-mass star-forming clumps were selected from the Millimeter Astronomy Legacy Team 90GHz (MALT90) survey data and their global chemical...
  • ATOMS IV Gas clumps properties and SFRs

    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...
  • 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...
  • High-z H-II star-forming galaxies

    We present independent determinations of cosmological parameters using the distance estimator based on the established correlation between the Balmer line luminosity,...
  • A Galactic survey of radio jets from MYSOs

    In conjunction with a previous southern-hemisphere work, we present the largest radio survey of jets from massive protostars to date with high-resolution (~0.04 arcsec) Jansky...
  • ALMA-IRDC from cloud to core scales

    Infrared dark clouds (IRDCs) are potential hosts of the elusive early phases of high mass star formation (HMSF). Here, we conduct an in-depth analysis of the fragmentation...
  • ALMA/NOEMA high-z star-forming galaxies

    We have used ALMA and NOEMA to study the molecular gas reservoirs in 61 ALMA-identified submillimetre galaxies (SMGs) in the COSMOS, UDS, and ECDFS fields. We detect ^12^CO...
  • Deuterated methanol in comet 67P/C-G

    Deuterated methanol is one of the most robust windows astrochemists have on the individual chemical reactions forming deuterium-bearing molecules and the physicochemical history...
  • Dense cores in the Serpens region from HGBS

    The Herschel Gould Belt survey mapped the nearby (d<500pc) star-forming regions to understand better how the prestellar phase influences the star formation process. Here, we...
  • Star formation in the clumps of the NAN complex

    The processes that regulate star formation within molecular clouds are still not well understood. Various star formation scaling relations have been proposed as an explanation,...
  • Properties of the Hydra cluster galaxies

    The nearby Hydra cluster (~50Mpc) is an ideal laboratory to understand, in detail, the influence of the environment on the morphology and quenching of galaxies in dense...
  • Resolved molecular gas in nearby galaxies

    A relationship between dust-reprocessed light from recent star formation and the amount of star-forming gas in a galaxy produces a correlation between Wide-field Infrared Survey...
  • Shocks in high-mass starless clump candidates

    In order to search for shocks in the very early stage of star formation, we performed single-point surveys of SiO J=1-0, 2-1, and 3-2 lines and the H_2_CO 2_12_-1_11_ line...
  • MUSE Analysis of Gas around Galaxies II

    We present a study of the metal-enriched cool halo gas traced by MgII absorption around 228 galaxies at z~0.8-1.5 within 28 quasar fields from the MUSE Analysis of Gas around...
