  • Candidate Double AGNs from Gaia & WISE (CDAGN)

    Making use of strong correlations between closely separated multiple or double sources and photometric and astrometric metadata in Gaia Early Data Release 3 (EDR3), we generate...
  • The CGS. X. Stellar mass parameters for bulges

    We measure optical colors for the bulges of 312 disk galaxies from the Carnegie-Irvine Galaxy Survey and convert their previously available R-band structural parameters to...
  • SDSS-IV MaNGA: pyPipe3D data for 10000 galaxies

    We present here the analysis performed using the pyPipe3D pipeline for the final MaNGA data set included in the Sloan Digital Sky Survey data release 17. This data set comprises...
  • Opt. & UV cat. of Abell 1882 galaxy members

    A rare opportunity to distinguish between internal and environmental effects on galaxy evolution is afforded by "SuperGroups," systems that are rich and massive, but include...
  • Color-metallicity relations of GCs. X. M87 spec.

    We obtained spectra of some 140 globular clusters (GCs) associated with the Virgo central cD galaxy M87 with the Subaru/FOCAS MOS mode. The fundamental properties of GCs such as...
  • E(V-I) reddening map of MCs from OGLE-IV RC stars

    We present the most extensive and detailed reddening maps of the Magellanic Clouds (MCs) derived from the color properties of Red Clump (RC) stars. The analysis is based on the...
  • ATLAS c-o colors and classification of asteroids

    We present here the c-o colors for identified Flora, Vesta, Nysa-Polana, Themis, and Koronis family members within the historic data set (2015-2018) of the Asteroid...
  • 8um cores in the spiral arms of nearby galaxies

    Spitzer Space Telescope observations of 15 spiral galaxies show numerous dense cores at 8{mu}m that are revealed primarily in unsharp mask images. The cores are generally...
  • A catalog of galaxies in direction of Perseus

    We present a catalog of 5437 morphologically classified sources in the direction of the Perseus galaxy cluster core, among them 496 early-type low-mass galaxy candidates. The...
  • Colors of the Outer Solar System Origins Survey

    The Colours of the Outer Solar System Origins Survey is acquiring near-simultaneous g, r, and J photometry of unprecedented precision with the Gemini North Telescope, targeting...
  • Am stars from LAMOST DR5

    The Large Sky Area Multi-Object Fibre Spectroscopic Telescope data release 5 (DR5) released more than 200,000 low-resolution spectra of early-type stars with a signal-to-noise...
  • NGVS XXV. Virgo globular clusters photometry

    The central region of the Virgo cluster of galaxies contains thousands of globular clusters (GCs), an order of magnitude more than the numbers found in the Local Group. Relics...
  • UGRK Photometry in the Hubble Deep field region

    Detection and photometry of sources in the U_n_, G, {R}, and K_s_ bands in a 9x9 arcmin^2^ region of the sky, centered on the Hubble Deep Field, are described. The data permit...
  • S-type stars from LAMOST MRS DR9 with Gaia DR2 data

    In this paper, we report on 606 S-type stars identified from Data Release 9 of the LAMOST medium-resolution spectroscopic (MRS) survey; 539 of them are reported for the first...
  • Variable hot subdwarf from Gaia DR2 and TESS

    Hot subdwarf stars are mostly stripped red giants that can exhibit photometric variations due to stellar pulsations, eclipses, the reflection effect, ellipsoidal modulation, and...
  • Active giant binaries from VSX and Gaia EDR3

    Sub-subgiant stars (SSGs) fall below the subgiant branch and/or red of the giant branch in open and globular clusters, an area of the color-magnitude diagram (CMD) not populated...
  • Herbig Ae/Be stars with IGRINS obs.

    Accretion plays an important role in protoplanetary disk evolution, and it is thought that the accretion mechanism changes between low- and high-mass stars. Here we characterize...
  • Pleiades members & escapee candidates with Gaia EDR3

    We search through an eight million cubic parsec volume surrounding the Pleiades star cluster and the Sun to identify both the current and past members of the Pleiades cluster...
  • Foundation Supernova Survey: SN Ia sample

    The ejecta velocities of Type Ia supernovae (SNe Ia), as measured by the SiII{lambda}6355 line, have been shown to correlate with other supernova properties, including color and...
  • HectoMAP Cluster Survey: clusters & BCGs

    We apply a friends-of-friends (FoF) algorithm to identify galaxy clusters and we use the catalog to explore the evolutionary synergy between brightest cluster galaxies (BCGs)...
