  • Unclassified B[e] stars in the MW, SMC and LMC

    We investigated 12 unclassified B[e] stars or candidates, 8 from the Galaxy, 2 from the Large Magellanic Cloud (LMC), and 2 from the Small Magellanic Cloud (SMC). Based on the...
  • Filaments hosting Planck Galactic cold clumps

    We present a statistical study of the relative orientation in the plane of the sky between interstellar magnetic fields and filaments hosting cold clumps. For the first time, we...
  • CORNISH project IV. Radio-selected galactic PN

    We present a new radio-selected sample of PNe from the CORNISH survey. We find 90 new PNe, of which 12 are newly discovered and 78 are newly classified as PN. A further 47...
  • APOGEE stars distance and extinction

    Using a Bayesian technology, we derived distances and extinctions for over 100000 red giant stars observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE)...
  • Maps of dust distribution in M31 bulge

    We map the dust distribution in the central 180" (~680pc) region of the M31 bulge, based on HST WFC3 and ACS observations in ten bands from near-ultraviolet (2700{AA}) to...
  • Dust and SSP-stellar parameters of M82

    We use near ultraviolet and optical photometry to investigate the dust properties in the nearby starburst galaxy M82. By combining imaging from the Swift/UVOT instrument and...
  • Coefficients for passband extinctions

    We present a method for obtaining the likelihood function of distance and extinction to a star given its photometry. The other properties of the star (its mass, age, metallicity...
  • Star clusters distances and extinctions. II.

    Until now, it has been impossible to observationally measure how star cluster scaleheight evolves beyond 1Gyr as only small samples have been available. Here, we establish a...
  • 3D extinction map of northern Galactic plane

    We present a three dimensional map of extinction in the Northern Galactic Plane derived using photometry from the IPHAS survey. We construct the map using a method based on a...
  • Star clusters distances and extinctions

    Determining star cluster distances is essential to analyse their properties and distribution in the Galaxy. In particular, it is desirable to have a reliable, purely photometric...
  • Synthetic supernova extinction curves

    We apply the supernova (SN) extinction curves to reproduce the observed properties of SST J1604+4304 which is a young infrared (IR) galaxy at z~1. The SN extinction curves used...
  • Stellar parameters and extinction

    Astrometric surveys provide the opportunity to measure the absolute magnitudes of large numbers of stars, but only if the individual line-of-sight extinctions are known....
  • Galactic RR Lyrae data

    We use accurate absolute proper motions and Two-Micron All-Sky Survey Ks -band apparent magnitudes for 364 Galactic RR Lyrae variables to determine the kinematical parameters of...
  • K extinction near the Galactic Centre

    We extract J and Ks magnitudes from the 2MASS Point Source Catalog for approximately 6 million stars with 8<Ks<13 in order to build an A_K_ extinction map within 10...
  • Extinction in MBM12

    Photoelectric magnitudes and color indices in the Vilnius seven-color system for 152 stars are used to investigate the interstellar extinction in the area of the Aries molecular...
  • Opt-IR counterparts of Chandra sources in CygOB2

    The young massive OB association Cygnus OB2, in the Cygnus X complex, is the closest (~1400pc) star-forming region to the Sun hosting thousands of young low-mass stars and up to...
  • The value-added COSMOS2020 catalog

    This work presents and releases a catalog of new photometrically derived physical properties for the ~10^5^ most well-measured galaxies in the COSMOS field on the sky. Using a...
  • HST/STIS low-resolution stellar library

    In order to provide fundamental stellar spectra that extend into the UV, Hubble Space Telescope's Space Telescope Imaging Spectrograph targeted 556 stars via proposals GO9088,...
  • The Ly{alpha} Reference Sample (LARS). XIV.

    We present Ly{alpha} imaging of 45 low-redshift star-forming galaxies observed with the Hubble Space Telescope. The galaxies have been selected to have moderate to high star...
  • Low-mass companions to KOIs observed with APOGEE

    We report the characterization of 28 low-mass (0.02M_{sun}<=M_2<=0.25M_{sun}_) companions to Kepler objects of interest (KOIs), eight of which were previously designated...
