  • Catalog of Star-Forming Regions in the Galaxy

    This Catalog of Star-Forming Regions in the Galaxy contains coordinates and fluxes of young objects in the radio and infrared, as well as data on the radial velocities of...
  • ALMA 3-mm sources in the Orion-KL region

    High-energy processes are ubiquitous even in the earliest stages of protostellar evolution. Motivated by the results of our systematic search for intense centimetre radio flares...
  • CQ Tau images in near-infrared

    We present new high-contrast images in near-infrared wavelengths ({lambda}c = 1.04, 1.24, 1.62, 2.18, and 3.78 um) of the young variable star CQ Tau, aiming to constrain the...
  • VLA compact radio sources in the ONC

    We present a newly enlarged census of the compact radio population towards the Orion Nebula Cluster (ONC) using high-sensitivity continuum maps (3-10uJy/beam) from a total of...
  • 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...
  • A faint companion around CrA-9

    Understanding how giant planets form requires observational input from directly imaged protoplanets. We used VLT/NACO and VLT/SPHERE to search for companions in the transition...
  • LMT/AzTEC 1.1mm Survey of Mon R2 dense cores

    We present a 1.1mm census of dense cores in the Mon R2 giant molecular cloud with the AzTEC instrument on the Large Millimetre Telescope. We detect 295 cores (209 starless and...
  • VVV high amplitude NIR variable stars

    We present the discovery of 816 high-amplitude infrared variable stars ({Delta}K_s_>1mag) in 119deg^2^ of the Galactic mid-plane covered by the VISTA Variables in the Via...
  • SVM selection of WISE YSO Candidates

    We explored the AllWISE catalogue of the Wide-field Infrared Survey Explorer mission and identified Young Stellar Object candidates. Reliable 2MASS and WISE photometric data...
  • Young clumps embedded in IRDC

    We present a catalogue of starless and protostellar clumps associated with infrared dark clouds (IRDCs) in a 40 degrees wide region of the inner Galactic plane (|b|<=1). We...
  • Torun methanol source catalogue

    We report the observations of 289 methanol maser sources at 6.7GHz obtained over a two month period with the Torun 32m telescope. The data form a catalogue of all objects north...
  • SOMA carbon-chain chemistry of IM protostars

    Evidence for similar chemical characteristics around low- and high-mass protostars has been found: in particular, a variety of carbon-chain species and complex organic molecules...
  • DM Tau JVLA image

    Previous high-angular-resolution 225GHz (~1.3mm) continuum observations of the transitional disk DM Tau have resolved an outer ring at 20-120au radii that is weakly azimuthally...
  • L1551 IRS 5 and NE jets radio images

    Using observations with e-MERLIN and the VLA, together with archival data from ALMA, we obtain high-resolution radio images of two binary YSOs: L1551 IRS 5 and L1551 NE,...
  • The SOUL view of IRAS20126+4104

    We exploit the increased sensitivity of the recently installed adaptive optics SOUL at the LBT to obtain new high-spatial-resolution near-infrared images of the massive young...
  • HD 163296 disk rings distribution of solids

    Observations at millimeter wavelengths of bright protoplanetary disks have shown the ubiquitous presence of structures such as rings and spirals in the continuum emission. The...
  • Linking high- and low-mass star formation

    Astronomers have yet to establish whether high-mass protostars form from high-mass prestellar cores, similar to their lower-mass counterparts, or from lower-mass fragments at...
  • ALMA continuum images of TW Hya

    A key piece of information to understand the origin and role of protoplanetary disk substructures is their dust content. In particular, disk substructures associated with gas...
  • Resolved molecular line observations

    Physical processes that govern the star and planet formation sequence influence the chemical composition and evolution of protoplanetary disks. Recent studies allude to an early...
  • IRAM intensity maps of 3 low-mass protostars

    Methanol is a key species in astrochemistry since it is the most abundant organic molecule in the interstellar medium and is thought to be the mother molecule of many complex...
