    Studying the accretion geometry of EXO 2030+375 at luminosities close to the propeller regime
    The Be X-ray binary EXO 2030+375was in an extended low-luminosity state during most of 2016. We observed this state with NuSTARand Swift, supported by...

    Submillimeter Polarization Spectrum in the Vela C Molecular Cloud
    Polarization maps of the Vela C molecular cloud were obtained at 250, 350, and 500 μm during the 2012 flight of the balloon-borne telescope BLASTPol. These...

    Supersonic Continuation of the Evershed Flow Outside a Sunspot as Observed with Hinode
    We report on the discovery of mostly horizontal field channels just outside sunspot penumbrae (in the so-called "moat" region) that are seen to sustain...

    Survival of molecular gas in a stellar feedback-driven outflow witnessed with the MUSE TIMER project and ALMA
    Stellar feedback plays a significant role in modulating star formation, redistributing metals, and shaping the baryonic and dark structure of galaxies - however...

    Synthesis of infrared Stokes spectra in an evolving solar chromospheric jet
    Chromospheric jets are plausible agents of energy and mass transport in the solar chromosphere, although their driving mechanisms have not yet been elucidated...
