    LIGHTS. The Thin Encircling Stellar Stream of NGC 3938
    We present a stellar stream found in images of the nearby, nearly face-on, late-type galaxy, NGC 3938 obtained for the Large Binocular Telescope Imaging of...

    Limitations of the Ca II 8542 Å Line for the Determination of Magnetic Field Oscillations
    Chromospheric umbral oscillations produce periodic brightenings in the core of some spectral lines, known as umbral flashes. They are also accompanied by...

    Limiting the Abundance of LIGO/Virgo Black Holes with Microlensing Observations of Quasars of Finite Size
    We present a simple but general argument that strongly limits the abundance of primordial black holes (PBHs) (or other unknown population of compact objects)...

    Limits on Hot Intracluster Gas Contributions to the Tenerife Temperature Anisotropy Map
    We limit the contribution of the hot intracluster gas, by means of the Sunyaev-Zeldovich effect, to the temperature anisotropies measured by the Tenerife...

    Limits on the Hard X-Ray Emission From the Periodic Fast Radio Burst FRB 180916.J0158+65
    FRB 180916.J0158+65 is one of the nearest, periodically repeating, and actively bursting fast radio bursts (FRBs) that has been localized to the outskirts of a...

    Limits on the Spin-Orbit Angle and Atmospheric Escape for the 22 Myr Old Planet AU Mic b
    We obtained spectra of the pre-main-sequence star AU Microscopii during a transit of its Neptune-sized planet to investigate its orbit and atmosphere. We used...

    Line Formation Theory for the Multiterm Atom with Hyperfine Structure in a Magnetic Field
    Within the framework of the quantum theory of polarized line formation, in the limit of complete frequency redistribution and of the collisionless regime, we...

    Line Shape Effects on Intensity Measurements of Solar Features: Brightness Correction to SOHO MDI Continuum Images
    Continuum intensity observations obtained with the Michelson Doppler Imager (MDI) on board the SOHO mission provide long time series of filtergrams that are...

    LINER-like Extended Nebulae in ULIRGs: Shocks Generated by Merger-Induced Flows
    In this work we studied the two-dimensional ionization structure of the circumnuclear and extranuclear regions in a sample of six low-z ultraluminous infrared...
