  • QSOs CaII absorbers

    We present a systematic study of weak intervening CaII absorbers at low redshift (z<0.5), based on the analysis of archival high-resolution (R>=45000) optical spectra of...
  • Heliospheric density and magnetic field model

    The radial evolution of the density of the plasma and the magnetic field in the heliosphere, especially in the region between the solar corona and the Earth's orbit, has been a...
  • Synthetic lines in the Sun

    We have computed synthetic spectra from a realistic 3D numerical simulation of the solar photosphere. We provide the spatially averaged spectra for selected lines that are...
  • Radial velocities of HD 10180

    Low-mass extrasolar planets are presently being discovered at an increased pace by radial velocity and transit surveys, which opens a new window on planetary systems. We are...
  • GJ3634 radial velocity and 4.5um flux

    We report on the detection of GJ3634b, a super-Earth of mass msini=7.0+/-0.9 Mearth and period P=2.64561+/-0.00066-day. Its host star is a M2.5 dwarf, has a mass of...
  • GALEX Ultraviolet Virgo Cluster Survey (GUViCS)

    The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete blind survey of the Virgo cluster covering ~40 sq. deg in the far UV (FUV, {lambda}eff=1539{AA},...
  • Archive of the FAI AZT-8

    The archive of digitized plates obtained on AZT-8 at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan. They represent the results of photometric observations of...
  • PDS-PPI VO server SIAP Version 2 Service

    The PDS-PPI VO server's sitewide SIAP version 2 service publishes all the images published through the site. For more advanced queries including uploads, all this data is also...
  • H.E.S.S. DL3 public test data release 1

    The release consists of event lists and instrument response functions for observations of various well-known gamma-ray sources (the Crab nebula, PKS 2155-304, MSH...
  • Data Central SIA2

    Image cutouts from large format, multi-wavelength mosaics hosted by Data Central. The main datasets are mosaics from DEVILS and GAMA surveys, obtained from a variety of facilities.
  • LOFAR LBA Sky Survey First Release

    The Low Frequency Array (LOFAR) is the only existing radio interferometer able to observe at ultra-low frequencies (<100MHz) with high resolution (<15-arcsec) and high...
  • Herschel map cutouts

    Image maps from the Herschel Space Observatory.
  • XAO Data Center TAP service

    The XAO Data Center's TAP end point. The Table Access Protocol (TAP) lets you execute queries against our database tables, inspect various metadata, and upload your own data. It...
  • MOJAVE. Persistent polarization in AGN jets

    We analysed the parsec-scale linear polarization properties of 436 active galactic nuclei (AGN) based on 15GHz polarimetric Very Long Baseline Array (VLBA) observations. We...
  • Tohoku University VO Server TAP service

    The Tohoku University VO Server's TAP end point. The Table Access Protocol (TAP) lets you execute queries against our database tables, inspect various metadata, and upload your...
