  • 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...
  • 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...
  • Anatomy of L1489 IRS with NOEMA I

    Over the past few years, chemical studies have revealed multiple structures in the vicinity of young stellar objects (YSOs). It has become evident that specific physical...
  • Core to UCHII region evolution in W49A

    We aim to identify and characterize cores in the high-mass proto-cluster W49, determine their evolutionary stages and measure the associated lifetimes. We built a catalog of 129...
  • IRAM-30m spectrum observed toward L1551 IRS 5

    Episodic accretion in protostars leads to luminosity outbursts that end up heating their surroundings. This rise in temperature pushes the snow lines back, enabling the...
  • H_2_CO production in HD 163296

    We analyze the radial distribution of H_2_CO and C^18^O in the protoplanetary disk around HD 163296, a Herbig Ae type protostar, with the aim of determining possible formation...
  • 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...
  • 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...
  • 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...
  • 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...
  • LRLL54361 protostar Herschel/PACS fluxes

    We report Herschel/Photodetector Array Camera and Spectrometer (PACS) photometric observations at 70 {mu}m and 160 {mu}m of LRLL54361, a suspected binary protostar that exhibits...
  • 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...
  • Young Stellar Objects from LAMOST and ZTF surveys

    The study of young stellar objects (YSOs) not only enhances our understanding of star formation and stellar evolution, but also contributes to broader areas of astrophysics,...
  • HD 163296 CI datacube

    In protoplanetary disks, atomic carbon is expected to originate from the PDR at the disk surface where CO is dissociated by UV photons coming from the stellar, or external...
