  • CHEPS cold Jupiters RV curves

    The population of long-period giant planets shapes planetary system architectures and formation pathways, but these `cold-Jupiters' remain relatively unexplored. Radial velocity...
  • Transition from outside-in to inside-out at z~2

    By combining high-resolution observations from JWST and HST, we have measured the stellar masses, star formation rates (SFRs), and multi- wavelength morphologies of galaxies in...
  • SN 2017ati light curves

    We present optical photometric and spectroscopic observations of the Type IIb supernova (SN) 2017ati. It reached the maximum light at about 27~d after the explosion and the...
  • IM Vir BVRI photometry and radial velocities

    We report extensive spectroscopic and differential photometric BVRI observations of the active, detached, 1.309-day double-lined eclipsing binary IM Vir, composed of a G7-type...
  • HAT-P-12 light curve

    We report on the discovery of HAT-P-12b, a transiting extrasolar planet orbiting the moderately bright V~12.8 K4 dwarf GSC 03033-00706, with a period P=3.2130598+/-0.0000021d,...
  • H{alpha} and UV SFR in the local volume

    Using a complete sample of ~300 star-forming galaxies within 11Mpc of the Milky Way, we evaluate the consistency between star formation rates (SFRs) inferred from the far...
  • Fluxes in nearby star-forming galaxies

    Compared to starburst galaxies, normal star-forming galaxies have been shown to display a much larger dispersion of the dust attenuation at fixed reddening through studies of...
  • Stromgren photometry in {omega} Cen

    We present new intermediate-band Stromgren photometry based on more than 300 u, v, b, y images of the Galactic globular cluster {omega} Cen. Optical data were supplemented with...
  • Carbon star candidates from LAMOST and SDSS

    Carbon stars are critical for understanding stellar evolution and exploring cosmic chemistry. This paper provides 7809 carbon star candidates identified from the Large-Area...
  • Asteroseismology of 687 TESS red giants

    The individual modes and asymptotic parameters are important characteristics of stellar oscillation. Using TESS 2 minute cadence data from Sectors 1 to 75, we perform...
  • Confirmed AGN type 1 & 2 from sp. in Kepler fields

    We utilized the Edelson & Malkan (2012, J/ApJ/751/52) and Stern+ 2012ApJ...753...30S selection techniques and other methods to identify active galactic nuclei (AGN)...
  • The California-Kepler Survey. XI. Activity

    Surveys of exoplanet host stars are valuable tools for assessing population level trends in exoplanets, and their outputs can include stellar ages, activity, and rotation...
  • JADES and FRESCO Ha-emitting galaxies at z=5.1-5.5

    HDF850.1 is the brightest submillimeter galaxy (SMG) in the Hubble Deep Field. It is known as a heavily dust-obscured star-forming galaxy embedded in an overdense environment at...
  • LBT-MODS long-slit opt. sp. of SDSS-FIRST galaxies

    We present a study investigating the influence of jets on galaxies exhibiting strong [OIII]{lambda}5007 emission, known as Green Peas and Green Beans. Our sample comprised 12...
  • TOI-1710 HARPS-N radial velocity curve

    The obliquity between a planet's orbital axis and its host star's spin axis provides crucial insights into planetary formation and migration. Planets with scaled semi-major axes...
  • Radial velocities of 11 new brown dwarfs from TESS

    We present the discovery of 11 new transiting brown dwarfs (BDs) and low-mass M dwarfs from NASA's Transiting Exoplanet Survey Satellite (TESS) mission: TOI-2844, TOI-3122,...
  • The California-Kepler Survey. X.

    In 2017, the California-Kepler Survey (CKS) published its first data release (DR1) of high-resolution optical spectra of 1305 planet hosts. Refined CKS planet radii revealed...
  • California-Kepler Survey. VII. Planet radius gap

    The distribution of planet sizes encodes details of planet formation and evolution. We present the most precise planet size distribution to date based on Gaia parallaxes, Kepler...
  • California-Kepler Survey (CKS). II. Properties

    We present stellar and planetary properties for 1305 Kepler Objects of Interest hosting 2025 planet candidates observed as part of the California-Kepler Survey. We combine...
  • RVs and photometry light curves of TOI-5624

    Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7, Vstar ~100pc away), a CHEOPS campaign in 2023 detected four planetary signals at P_b_~3.4,...
