  • Rosette Nebula globules

    The Rosette nebula is an HII region ionized mainly by the stellar cluster NGC 2244. Elephant trunks, globules, and globulettes are seen at the interface where the HII region and...
  • ALLSMOG final data release. A new APEX CO survey

    We present the final data release of the APEX low-redshift legacy survey for molecular gas (ALLSMOG), comprising CO(2-1) emission line observations of 88 nearby, low-mass...
  • G345.45+1.50 ^13^CO(3-2) clumps

    Ring-like structures in the interstellar medium (ISM) are commonly associated with high-mass stars. Kinematic studies of large structures in giant molecular clouds (GMCs) toward...
  • Reduced high-resolution HI and CO data cubes

    Intermediate-velocity clouds (IVCs) are HI halo clouds that are likely related to a Galactic fountain process. In-falling IVCs are candidates for the re-accretion of matter onto...
  • Nearby AGN ^12^CO and H{alpha} maps

    We present an analysis of the relation between star formation rate (SFR) surface density ({Sigma}SFR) and mass surface density of molecular gas ({Sigma}H2), commonly referred to...
  • YSOs APEX-CHAMP^+^ high-J CO maps

    During the embedded stage of star formation, bipolar molecular outflows and UV radiation from the protostar are important feedback processes. Both processes reflect the...
  • Group-dominant elliptical galaxies CO spectra

    We present IRAM 30m telescope observations of the CO(1-0) and (2-1) lines in a sample of 11 group-dominant elliptical galaxies selected from the CLoGS nearby groups sample. Our...
  • C^18^O(1-0) and N_2_H^+^(1-0) in L1495/B213

    Core condensation is a critical step in the star-formation process, but it is still poorly characterized observationally. We have studied the 10pc-long L1495/B213 complex in...
  • Molecular gas in Hickson Compact Groups

    We study the effect of the extreme environment in Hickson Compact Groups (HCGs) on the molecular gas mass, M_H2_, and the star formation rate (SFR) of galaxies as a function of...
  • M33 CO(2-1) and HI integrated intensity maps

    We present high-resolution large-scale observations of the molecular and atomic gas in the Local Group galaxy M 33. The observations were carried out using the HEterodyne...
  • Gas content in 1038 interacting galaxies

    A study of the gas content in 1038 interacting galaxies, essentially selected from Arp (), Arp and Madore (), Vorontsov-Velyaminov () catalogues and some of the published...
  • CO velocities in southern HII regions

    We present ^12^CO(1-0), ^12^CO(2-1) and/or ^13^CO(1-0) observations in the direction of HII regions located in the southern Galactic plane. The CO lines have been fitted with...
  • Planck CO revisited

    The Planck space mission has observed the first three rotational lines of emission of Galactic CO. Those maps, however, are either noisy, or contaminated by astrophysical...
  • IRAM observations in pre-star forming regions

    The goal of the IRAM key-project ``Small-scale structure of pre-star forming regions'' is to map three nearby (d~150pc), quiescent molecular clouds with a high angular and...
  • Massachusetts-Stony Brook Galactic Plane CO Survey

    The Massachusetts-Stony Brook Galactic Plane CO Survey data consists of 40551 12CO(J=1-0) spectra covering Galactic longitudes 8-90 deg and latitudes -1.05 to +1 deg. The...
  • CO clouds in the Galactic Center from NANTEN

    In order to better understand molecular clouds and their properties toward the Galactic center region, we have analyzed the NANTEN database of ^12^CO (J=1-0) and ^13^CO (J=1-0)...
  • CO emission towards Southern dark clouds

    Using the 22-m 'Mopra' antenna (near Coonabarabran, NSW) of the Australia Telescope National Facility (ATNF), we have observed emission from the 115-GHz J=1-0 transition of CO...
  • Extragalactic star-forming regions

    The relationships between atomic and molecular hydrogen and dust of various sizes in extragalactic star-forming regions are considered, based on observational data from the...
  • ^13^CO emission in the MWISP ^12^CO molecular clouds

    After morphological classification of 18190 ^12^CO molecular clouds, we further investigate the properties of their internal molecular gas structures traced by the ^13^CO...
  • High-velocity dispersion compact clouds in the CMZ

    This study developed an automated identification procedure for compact clouds with broad velocity widths in the spectral-line data cubes of highly crowded regions. The procedure...
