  • Synthetic Spectra Convolution Service

    Convolution of normalized synthetic stellar spectra. Up to 3 successive convolutions are allowed on a adjustable portion of a synthetic spectrum, in order to mimic an...
  • Polarbase SSAP service for ESPaDOns/Narval spectra

    This database contains reduced spectra from Narval and ESPaDOns instruments
  • Be Stars Spectra

    The BeSS database assembles classical Be star spectra obtained by professional and amateur astronomers at any wavelength, epoch, and spectral resolution.
  • Multiply lensend quasar systems in the DESI Surveys

    The time delay between multiple images of strongly lensed quasars is a powerful tool for measuring the Hubble constant (H0). To achieve H0 measurements with higher precision and...
  • Ha spectroscopic obs. of Pleione from 2005-2019

    We acquired H{alpha} spectroscopic observations from 2005 to 2019 showing Pleione has transitioned from a Be phase to a Be-shell phase during this period. Using the radiative...
  • Dynamical masses of z~0.8 galaxies from LEGA-C

    We compare dynamical mass estimates based on spatially extended stellar and ionized gas kinematics (M_dyn, and M_dyn,eml, respectively) of 157 star-forming galaxies at...
  • Light curve & radial velocities for PSRJ1810+1744

    Keck-telescope spectrophotometry of the companion of PSR-J1810+1744 shows a flat, but asymmetric light-curve maximum and a deep, narrow minimum. The maximum indicates strong...
  • Radial velocity in a Wolf-Rayet/O-star couple

    We present the first visual orbit for the nitrogen-rich Wolf-Rayet binary, WR133 (WN5o+O9I), based on observations made with the CHARA Array and the MIRC-X combiner. This orbit...
  • Radial velocity follow up of HD 307842

    We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD307842 (TOI-784). The planet has a period of 2.8days, and the radial...
  • Optical spectroscopy of blazars for CTA. III

    Blazars, which include BL Lacs and flat-spectrum radio quasars (FSRQs), represent the brightest persistent extragalactic sources in the high-energy (HE; 10MeV-100GeV) and...
  • Spectroscopic catalog of VIPERS

    We investigate the influences on the evolution of the Fundamental Metallicity Relation of different selection criteria. We used 5487 star-forming galaxies at a median redshift...
  • Northern HI Parkes All Sky Survey Catalogue (HIPASS)

    The Northern HIPASS catalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of...
  • HI spectral properties of galaxies

    We present a homogeneous compilation of HI spectral parameters extracted from global 21cm line spectra for some 9000 galaxies in the local universe (heliocentric velocity...
  • HI Parkes All Sky Survey Catalogue (HIPASS)

    The HI Parkes All-Sky Survey (HIPASS) Catalogue forms the largest uniform catalogue of HI sources compiled to date, with 4315 sources identified purely by their HI content. The...
  • Radio survey of clusters of galaxies

    Observations of Abell clusters at 11.1, 6.2, 6.3 and 2.8cm with the 100m Effelsberg telescope. The data were compiled by H.J. Andernach. Cone search capability for table...
  • Catalog of Stellar Velocity Dispersions

    A catalog of central stellar velocity dispersion measurements is presented, current through 1984. The catalog includes 1096 measurements of 725 galaxies. A set of 51 standard...
  • SDSS quasar catalog, sixteenth data release (DR16Q)

    We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog...
  • SDSS quasar catalog, fourteenth data release

    We present the data release 14 Quasar catalog (DR14Q) from the extended Baryon Oscillation Spectroscopic Survey (eBOSS) of the Sloan Digital Sky Survey IV (SDSS-IV). This...
  • SDSS quasar catalog: twelfth data release

    We present the Data Release 12 Quasar catalog (DR12Q) from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky SurveyIII. This catalog includes all...
  • SDSS quasar catalog: tenth data release

    We present the Data Release 10 Quasar (DR10Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS...
