  • Chemodynamically tagged groups of CEMP stars. I.

    We construct a sample of 644 carbon-enhanced metal-poor (CEMP) stars with abundance analyses based on moderate- to high-resolution spectroscopic studies. Dynamical parameters...
  • Star formation in isolated galaxies

    We use the FUV fluxes measured with the GALEX to study the star formation properties of galaxies collected in the Local Orphan Galaxies catalog (LOG, 2011AstBu..66....1K). Among...
  • NGC6397 low-mass variable stars

    We have conducted a photometric survey of the globular cluster NGC 6397 in a search for variable stars. We obtained ~11h of time-resolved photometric images with one European...
  • UV-Optical galaxy color-magnitude diagram I.

    We have analyzed the bivariate distribution of galaxies as a function of ultraviolet-optical colors and absolute magnitudes in the local universe. The sample consists of...
  • Infrared observations of the Pleiades

    We make use of new near- and mid-IR photometry of the Pleiades cluster in order to help identify proposed cluster members. We also use the new photometry with previously...
  • Population synthesis in the blue. IV

    We present a new set of model predictions for 16 Lick absorption line indices from H{delta} through Fe5335 and UBV colors for single stellar populations with ages ranging...
  • The BOSS emission-line lens survey. III.

    We introduce the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey GALaxy-Ly{alpha} EmitteR sYstems (BELLS GALLERY) Survey, which is a Hubble Space...
  • Abell 576 galaxies magnitude and velocities

    We analyse the galaxy population and dynamics of the galaxy cluster A576; the observational constraints include 281 redshifts (230 new), R-band CCD galaxy photometry over a...
  • Brightest Cluster Galaxies velocities

    We investigate the use of Brightest Cluster Galaxies (BCGs) as standard candles for measuring galaxy peculiar velocities on large scales. We have obtained precise large-format...
  • Speckle observations of KOI

    We present the first results from a speckle imaging survey of stars classified as candidate exoplanet host stars discovered by the Kepler mission. We use speckle imaging to...
  • Kepler Mission. II. Eclipsing binaries in DR2

    The Kepler Mission (launched in 2009 March) provides nearly continuous monitoring of ~156000 objects with unprecedented photometric precision. Coincident with the first data...
  • Asiago-ESO/RASS QSO survey. II.

    This is the second paper of a series describing the Asiago-ESO/RASS QSO survey, a project aimed at the construction of an all-sky, statistically well defined sample of very...
  • Small Drift Scan Survey Galaxies Northern Sky

    The file is an ASCII text file containing data for 1053 galaxies brighter than 18.0 mag. in the filter used. The effective wavelength of this filter for objects that have the...
  • CPASJ2 catalogue

    According to the cooperation between Beijing, San Juan and La Plata Astronomical Observatories, the photoelectric astrolabe Mark II(PAII) of the Beijing Astronomical Observatory...
  • Gaia EDR3 and Johnson-Kron-Cousins standards

    In the era of large surveys and space missions, it is necessary to rely on large samples of well-characterized stars for inter-calibrating and comparing measurements from...
  • V352 CMa V-band differential light curve

    We perform detailed time series analysis for V-band photometry of the young active star V352 CMa to investigate the characteristics of its magnetic activity in both long and...
  • The Million Quasars (Milliquas) catalogue, version 8

    This is a compendium of 907144 type-I QSOs and AGN, largely complete from the literature to 30 June 2023. 66,026 QSO candidates are also included, calculated via radio/X-ray...
  • The Million Quasars (Milliquas) catalogue, version 7.2

    This is a compendium of 829666 type-I QSOs and AGN, largely complete from the literature to 30 April 2021 including SDSS-DR16 quasars and VLASS radio. Also included are 703348...
  • The Million Quasars (Milliquas) catalog (6.3)

    This is a compendium of 623,004 type-I QSOs and AGN, largely complete from the literature to 15 June 2019 including SDSS-DR15 and LAMOST QSO DR5. Also included are approx 1.32M...
  • The Million Quasars (Milliquas) catalog (V5.2)

    This is a compendium of 607,208 type-I QSOs and AGN, largely complete from the literature to 5-August-2017, including the release of SDSS-DR14. Also included are ~1.35M...
