    NICS-TNG Low-Resolution 0.85-2.45 micron Spectra of L Dwarfs: A Near-Infrared Spectral Classification Scheme for Faint Dwarfs
    We present complete near-infrared (0.85-2.45 μm), low-resolution (~100) spectra of a sample of 26 disk L dwarfs with reliable optical spectral type...

    No Evidence for a Dependence of the Mass-Size Relation of Early-type Galaxies on Environment in the Local Universe
    The early-type galaxy (ETG) mass-size relation has largely been studied to understand how these galaxies assembled their mass. One key observational result of...

    No Evidence for Critical Balance in Field-aligned Alfvénic Solar Wind Turbulence
    The properties of Alfvénic solar wind turbulence have been studied for decades using spacecraft measurements. In particular, the observation of spectral...

    No Surviving Companion in Kepler's Supernova
    We have surveyed Kepler’s supernova remnant in search of the companion star of the explosion. We have gone as deep as 2.6 L ⊙ in all stars within 20% of the...

    Non-coherent Continuum Scattering as a Line Polarization Mechanism
    Line scattering polarization can be strongly affected by Rayleigh scattering at neutral hydrogen and Thomson scattering at free electrons. Often a...

    Non-detection of He I in the Atmosphere of GJ 1214b with Keck/NIRSPEC, at a Time of Minimal Telluric Contamination
    Observations of helium in exoplanet atmospheres may reveal the presence of large gaseous envelopes and indicate ongoing atmospheric escape. Orell-Miquel et al....
