  • Short period eclipsing binaries from Kepler data

    During the primary Kepler mission, between 2009 and 2013, about 150,000 preselected targets were observed with a 29.42 minute long cadence. However, a survey of background stars...
  • The PTF core-collapse SN host-galaxy sample. I.

    Several thousand core-collapse supernovae (CCSNe) of different flavors have been discovered so far. However, identifying their progenitors has remained an outstanding open...
  • Ks absolute magnitudes from LAMOST for OB stars

    We present a data-driven method to estimate absolute magnitudes for O- and B-type stars from the LAMOST spectra, which we combine with Gaia DR2 parallaxes to infer distance and...
  • MIR outbursts in nearby SDSS gal. (MIRONG). I.

    Optical time-domain astronomy has grown rapidly in the past decade, but the dynamic infrared sky is rarely explored. Aiming to construct a sample of mid-infrared outbursts in...
  • Stellar bow shock nebulae spectroscopic obs.

    Arcuate mid-infrared nebulae known as stellar bow shock nebulae (SBNe) have been previously hypothesized to be supported by the strong stellar winds and/or luminosity of massive...
  • NGVS. XXXIV. Ultracompact dwarf galaxies in Virgo

    We present a study of ultracompact dwarf (UCD) galaxies in the Virgo cluster based mainly on imaging from the Next Generation Virgo Cluster Survey (NGVS). Using ~100deg^2^ of...
  • Edge-on HI-rich LSB galaxies from ALFALFA

    Low surface brightness galaxies (LSBGs) are defined as galaxies that are fainter than dark night sky and are important for studying our universe. Particularly, edge-on galaxies...
  • X-shaped radio galaxies from FIRST

    We present a catalog of 290 "winged" or X-shaped radio galaxies (XRGs) extracted from the latest (2014 December 17) data release of the "Very Large Array Faint Images of the...
  • Linear structural param. of SDSS+UKIDSS+WISE gal.

    Accurate measurements of galaxy structure are prerequisites for quantitative investigation of galaxy properties or evolution. Yet galaxy inclination, through projection and...
  • OSSOS. XII. Subaru/HSC obs. of 65 TNOs

    We present variability measurements and partial light curves of trans-Neptunian objects (TNOs) from a two-night pilot study using Hyper Suprime-Cam (HSC) on the Subaru Telescope...
  • CANDELS/SHARDS multiwavelength cat. in GOODS-N

    We present a WFC3 F160W (H-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts,...
  • 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...
  • Searching for super-fast rotators using PS1

    A class of asteroids, called large super-fast rotators (large SFRs), have rotation periods shorter than 2hr and diameters larger than ~0.3km. They pose challenges to the usual...
  • Opt. & NIR spectral atlas of 16 2MASS NIR-red AGNs

    We present medium-resolution spectra (R~2000-4000) at 0.4-1.0{mu}m and 0.7-2.5{mu}m of 16 active galactic nuclei (AGNs) selected with red color in the near-infrared (NIR) of...
  • SPLASH-SXDF multi-wavelength photometric catalog

    We present a multi-wavelength catalog in the Subaru/XMM-Newton Deep Field (SXDF) as part of the Spitzer Large Area Survey with Hyper-Suprime-Cam (SPLASH). We include the newly...
  • Physical parameters of ~300000 SDSS-DR12 QSOs

    We use the Sloan Digital Sky Survey (SDSS) Quasar Data Release 12 (DR12Q), containing nearly 300000 active galactic nuclei (AGNs), to calculate the monochromatic luminosities at...
  • The evolution of cataclysmic variables

    We present an attempt to reconstruct the complete evolutionary path followed by cataclysmic variables (CVs), based on the observed mass-radius relationship of their donor stars....
  • New HIP-based parallaxes for 424 faint stars

    We present a catalog of 424 common proper-motion companions to Hipparcos stars with good (>3{sigma}) parallaxes, thereby effectively providing new parallaxes for these...
  • PS1 z>5.6 QSO Survey. III. z~6 quasar LF

    We present the z~6 type-1 quasar luminosity function (QLF), based on the Pan-STARRS1 (PS1) quasar survey. The PS1 sample includes 125 quasars at z~5.7-6.2, with...
  • WISE-2MASS (W2M) quasars and red QSOs with sp.

    We present a highly complete sample of broad-line (Type 1) QSOs out to z~3 selected by their mid-infrared colors, a method that is minimally affected by dust reddening. We...
