  • (16) Psyche images

    Asteroid (16) Psyche is the target of the NASA Psyche mission. It is considered one of the few main-belt bodies that could be an exposed proto-planetary metallic core and that...
  • Integral-shaped filament NH_3_ observations

    Recent observations suggest a scenario in which filamentary structures in the interstellar medium represent the first step towards clumps/cores and eventually star formation....
  • WISE/NEOWISE Mars-crossing asteroids

    Mars-crossing asteroids (MCs) are a dynamically unstable group between the main belt and the near-Earth populations. Characterising the physical properties of a large sample of...
  • ATLASGAL dense filamentary structures

    We study the properties of filamentary structures from the ATLASGAL survey. We use the DisPerSE algorithm to identify spatially coherent structures located across the...
  • PCF, SpecB or SDSSB asteroids parameters

    B-type asteroids constitute a peculiar spectral class within the C-complex. Previous work has pointed out the difference between the visible geometric albedos of B-types and...
  • Galactic Cold Cores. IV. Cold sub-mm sources

    For the project Galactic cold cores, Herschel photometric observations were carried out as a follow-up of cold regions of interstellar clouds previously identified with the...
  • CALIFA DR2

    This paper describes the Second Public Data Release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. The data for 200 objects are made public, including the...
  • NGC1600, NGC4125, NGC7619 extended spectroscopy

    We present high quality long slit spectra along the major and minor axes out to 1.5-2R_e_ (14-22kpc) of three bright elliptical galaxies (NGC1600, NGC4125, NGC7619) obtained at...
  • Radial velocities in clusters of galaxies. V.

    As a part of our galaxy-cluster redshift survey, we present a set of 79 new velocities in the 4 clusters Abell 376, Abell 970, Abell 1356, and Abell 2244, obtained at...
  • Nearby open clusters tidal radii and masses

    In a previous paper we obtained King's parameters for 236 of 650 Galactic open clusters identified in the ASCC-2.5 (Kharchenko, 2001, Cat. ). Our aims is the estimate tidal...
  • Nearby open clusters radii and masses

    The table presents tidal parameters and masses of 236 open clusters in the nearest kiloparsecs around the Sun. The parameters are derived from a fitting of three-parameter King...
  • Morphologies in the Cepheus Flare region

    These tables contain the data of the cloud sample on which the study of the relationships between cloud morphology, optical and IR properties, and star formation is based. The...
  • BVRI imaging of the Coma cluster

    We have obtained deep and wide field imaging of the Coma cluster of galaxies with the CFH12K camera at CFHT in the B, V, R and I filters. In this paper, we present the...
  • AMIGA. II. Morphological refinement

    We present a refinement of the optical morphologies for galaxies in the Catalog of Isolated Galaxies (Karachentseva et al., 1973, Cat. ) that forms the basis of the AMIGA...
  • Catalogue of dust clouds in the Galaxy

    The file cdn.dat is an unified dust cloud catalogue of the Galaxy. Considering an initial list of approximately 6500 entries we condensed them into a cross-identified all-sky...
  • Small-scale structures in HI hole of M33

    Recent high-resolution HI observations of M33 reveal a large number of regions that are devoid of emission. We interpret these regions as holes formed by interstellar winds; a...
  • VIRMOS deep imaging survey. VVDS-F02 catalog

    The Franco-Italian VIRMOS project has delivered the VIMOS spectrograph for the European Southern Observatory Very Large Telescope (ESO-VLT). VIMOS is a VIsible imaging...
  • The Guide Star Catalog, Version 2.4.2 (GSC2.4.2)

    The GSC II is an all-sky catalog based on 1" resolution scans of the photographic Sky Survey plates, at two epochs and three bandpasses, from the Palomar and UK Schmidt...
  • Combined NVSS-FIRST Galaxies (CoNFIG) sample

    The CoNFIG (Combined NVSS-FIRST Galaxies) sample is a new sample of 274 bright radio sources at 1.4GHz. It was defined by selecting all sources with S1.4GHz-1.3Jy from the NRAO...
  • Tully-Fisher relation for SDSS galaxies

    In this paper, we derive scaling relations between photometric observable quantities and disc galaxy rotation velocity V_rot_ or Tully-Fisher relations (TFRs). Our methodology...
