    Near-infrared cross-dispersed spectroscopy of brown dwarf candidates in the UpperSco association
    We present near-infrared (1.15-2.50μm) medium-resolution (R = 1700) spectroscopy of a sample of 23 brown dwarf candidates in the young UpperSco association. We...

    Near-infrared emission lines trace the state-independent accretion disc wind of the black hole transient MAXI J1820+070
    The black hole transient MAXI J1820+070 displayed optical P Cyg profiles and other wind-related emission line features during the hard state of its discovery...

    Near-infrared polarimetric adaptive optics observations of NGC 1068: a torus created by a hydromagnetic outflow wind
    We present J' and K' imaging linear polarimetric adaptive optics observations of NGC 1068 using MMT-Pol on the 6.5-m MMT. These observations allow us to study...

    Near-ultraviolet absorption distribution of primitive asteroids from spectrophotometric surveys. I. Radial distribution
    Context. Hydrated minerals, such as phyllosilicates, on asteroids can provide constraints on the temperature or compositional distribution of the early Solar...
  • Publication
    Near-ultraviolet to visible spectroscopy of the Themis and Polana-Eulalia complex families
    Context. Spectrophotometry data of asteroids obtained in the 1980s showed that there are large variations in their near-ultraviolet (NUV) reflectance spectra...

    Nearby supernova host galaxies from the CALIFA Survey. I. Sample, data analysis, and correlation to star-forming regions
    We use optical integral field spectroscopy (IFS) of nearby supernova (SN) host galaxies (0.005 2.4 Gyr, respectively) than the massive SN Ia hosts (0.04%, 2.01%...
