  • Study of clumps, cores and hubs with ALMA

    The physical processes behind the transfer of mass from parsec-scale clumps to massive star-forming cores remain elusive. We investigate the relation between the clump...
  • NGC 6822 massive young stellar objects

    We present a supervised machine learning methodology to classify stellar populations in the Local Group dwarf-irregular galaxy NGC 6822. Near-IR colours (J-H, H-K, and J-K),...
  • Red Be Stars in the LMC and the SMC

    We revisit the subject of Be candidate stars towards the Magellanic Clouds, previously studied by the authors using SPM4 proper motions. We obtain Gaia DR2 parallaxes and proper...
  • Study of relativistic jets in blazar objets

    Our understanding of the unification of jetted AGN has evolved greatly as jet samples have increased in size. Here, based on the largest-ever sample of over 2000 well-sampled...
  • WISDOM Project IX study of GMCs in NGC 4429

    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...
  • 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...
  • GMC's properties cat. in Cen A mol. disc

    We present the first census of giant molecular clouds (GMCs) complete down to 106 M_{sun} and within the inner 4 kpc of the nearest giant elliptical and powerful radio galaxy,...
  • 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...
  • 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...
  • New constraints on the 1.4GHz source counts

    We present a study of the 1173 sources brighter than S_1.4GHz_=120{mu}Jy detected over an area of ~1.4deg^2^ in the Lockman Hole field. Exploiting the multiband information...
  • Accretion history of massive stars

    The mass growth of protostars is a central element to the determination of fundamental stellar population properties such as the initial mass function. Constraining the...
  • IR and sub-mm variability in protostars

    We study the relationship between the mid-infrared (mid-IR) and sub-millimetre (sub-mm) variability of deeply embedded protostars using the multi-epoch data from the Wide-field...
  • SCUBA-2-COSMOS field brightest sub-mm sources

    We present an ALMA study of the ~180 brightest sources in the SCUBA-2 850-{mu}m map of the COSMOS field from the S2COSMOS survey, as a pilot study for AS2COSMOS - a full survey...
  • SCUBA-2 overdensities in candidate protoclusters

    We measure the 850-{mu}m source densities of 46 candidate protoclusters selected from the Planck high-z catalogue (PHz) and the Planck Catalogue of Compact Sources (PCCS) that...
  • Properties of giant molecular clouds in NGC 1300

    Star formation activity depends on galactic-scale environments. To understand the variations in star formation activity, comparing the properties of giant molecular clouds...
  • A search for the lenses in the HerBS sample

    Verifying that sub-mm galaxies are gravitationally lensed requires time-expensive observations with oversubscribed high-resolution observatories. Here, we aim to strengthen the...
  • Dusty supernova remnants in the Galactic plane

    We search for far-infrared (FIR) counterparts of known supernova remnants (SNRs) in the Galactic plane (360{deg} in longitude and b=+/-1{deg}) at 70-500{mu}m with Herschel. We...
  • Star formation and 6.7GHz methanol masers

    Methanol masers at 6.7GHz are the brightest of class II methanol masers and have been found exclusively towards massive star-forming regions. These masers can thus be used as a...
  • Dust clumps associated with methanol masers

    We have constructed the largest sample of dust-associated class II 6.7GHz methanol masers yet obtained. New measurements from the Methanol Multibeam (MMB) survey were combined...
