  • JADES NIRCam & NIRSpec phot. & line fluxes cat. (DR1-DR3)

    JWST has revolutionized the field of extragalactic astronomy with its sensitive and high-resolution infrared view of the distant Universe. Adding to the new legacy of JWST...
  • Galaxy Clusters from SCUSS

    This paper presents the identification of galaxy clusters from the photometric redshift catalog based on three imaging surveys of SCUSS, Sloan Digital Sky Survey, and unWISE. By...
  • AKARI Near Infrared Asteroid Spectral Catalog V1

    Knowledge of water in the solar system is important for the understanding of a wide range of evolutionary processes and the thermal history of the solar system. To explore the...
  • LHS 3154 RV and activity indicators

    Theories of planet formation predict that low-mass stars should rarely host exoplanets with masses exceeding that of Neptune. We used radial velocity observations to detect a...
  • 51 Eri b near-infrared spectrum

    Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric composition and luminosity, which is influenced by their formation...
  • APOGEE DR17 standard stars radial velocities

    We present an updated catalog of 46753 radial velocity (RV) standard stars selected from the APOGEE DR17. These stars cover the Northern and Southern Hemispheres almost evenly,...
  • New emission-line galaxies and HII regions

    This work is to retrieve emission-line spectra from the "Unknown" data set in LAMOST DR7 V1.2, most of which are low signal-to-noise ratios spectra. In the work, we perform...
  • ZTF DR1 light curves of SNe Type Ia

    Type Ia supernovae (SNe Ia) in the nearby Hubble flow are excellent distance indicators in cosmology. The Zwicky Transient Facility (ZTF) has observed a large sample of SNe from...
  • Hydra I cluster study with H I emission

    We present results from our analysis of the Hydra I cluster observed in neutral atomic hydrogen (H I) as part of the Widefield ASKAP L-band Legacy All-sky Blind Survey...
  • Nearby main-sequence stars abundances

    To date, we have access to enormous inventories of stellar spectra that allow the extraction of atmospheric parameters and chemical abundances essential in stellar studies....
  • Magellan/FIRE quasar [OIII] spectra

    Understanding the links between different phases of outflows from active galactic nuclei is a key goal in extragalactic astrophysics. Here, we compare [OIII] {lambda}{lambda}...
  • WASP-127 b LCs, WASP-96 b transmission spectra

    We present TransitFit, a package designed to fit exoplanetary transit light-curves. TransitFit offers multi-epoch, multi-wavelength fitting of multi-telescope transit data....
  • 4 A-type stars abundances and spectra

    We present chemical composition and fundamental parameters (the effective temperature, surface gravity and radius) for four sharp-lined A-type stars gamma Gem (HD 41705),...
  • CQ Tau images in near-infrared

    We present new high-contrast images in near-infrared wavelengths ({lambda}c = 1.04, 1.24, 1.62, 2.18, and 3.78 um) of the young variable star CQ Tau, aiming to constrain the...
  • Silicate clouds in ultracool dwarfs

    We present a uniform analysis of all mid-infrared R~90 spectra of field M5-T9 dwarfs obtained with the Spitzer Infrared Spectrograph (IRS). The sample contains 113 spectra out...
  • Study of Kepler's FGKM stars

    While stellar rotation periods P_rot_ may be measured from broad-band photometry, the photometric modulation becomes harder to detect for slower rotators, which could bias...
  • RR Lyrae study with ZTF DR3 light curves

    We present an RR Lyrae (RRL) catalogue based on the combination of the third data release of the Zwicky Transient Facility (ZTF DR3) and Gaia EDR3. We use a multistep...
  • Red Be Stars in the LMC and the SMC

    We revisit the subject of Be candidate stars towards the Magellanic Clouds, previously studied by the authors using SPM4 proper motions. We obtain Gaia DR2 parallaxes and proper...
  • Tidal tails in the open cluster NGC 752

    We utilize the robust membership determination algorithm, ML-MOC, on the precise astrometric and deep photometric data from Gaia Early Data Release 3 within a region of radius 5...
  • Period-luminosity-metallicity relation of RRLs

    This paper presents results from photometric and statistical-parallax analysis of a sample of 850 field RR Lyrae (RRL) variables. The photometric and spectroscopic data for our...
