  • (16) Psyche. VLT/SPHERE images and shape models

    Asteroid (16) Psyche is the largest M-type asteroid in the main belt and the target of the NASA Psyche mission. It is also the only asteroid of this size (D>200km) known to...
  • (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...
  • Structure of Herbig AeBe disks at mas scale

    The aims of this article are to infer the radial and vertical structure at ~au scale of these disks, and the properties of the dust grains: composition and characteristic size....
  • Kohonen selected E+A galaxies from SDSS DR7

    We created and analysed a large sample of local (z<0.4) post-starburst (PSB) galaxies. In the colour-mass diagram, the PSB sample is clearly concentrated towards the region...
  • Kinematical profiles of nearby galaxies

    We present the largest catalog of detailed stellar kinematics of the central parts of nearby galaxies, which includes higher moments of the line-of-sight velocity distribution...
  • 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...
  • VEGAS-SSS photometry of NGC3115

    We present a study of globular clusters (GCs) and other small stellar systems (SSSs) in the field of NGC 3115, observed as part of the ongoing wide-field imaging survey VEGAS,...
  • 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...
  • GMRT Radio Halo Cluster Survey diffuse sources

    To gain further insight on the origin of diffuse radio sources in galaxy clusters and their connection with cluster merger processes, we performed GMRT low frequency...
  • 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...
  • High mass protostellar objects physical parameters

    In a previous work (Paper I, Kumar & Grave, 2007A&A...472..155K) a sample of 380 HMPO targets was studied using the GLIMPSE point source catalog and images. A...
  • Shape parameters for 650 open clusters

    Ellipticities have been determined for only a few tens of open clusters. We derive the observed and modelled shape parameters (apparent ellipticity and orientation of the...
  • Radio detections of 3G sources

    A considerable fraction of the gamma-ray sources discovered with the Energetic Gamma-Ray Experiment Telescope (EGRET) remain unidentified. The EGRET sources that have been...
  • 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...
  • Multi-epoch VLBI survey of CJF sources

    Global VLBI and VLBA observations (5GHz) of 293 sources of the CJF-sample have been conducted between 1990 and 2001. In total, thirteen separate observing campaigns have been...
