    The dependence of the magnetism of a near-limb sunspot on height
    Context. The physical parameters of the sunspot are not fully understood, especially the height dependence of the magnetic field. So far, it is also an open...

    The diagnostic potential of the weak field approximation for investigating the quiet Sun magnetism: the Si I 10 827 Å line
    Aims: We aim to investigate the validity of the weak field approximation (WFA) for determining magnetic fields in quiet regions of the solar photosphere using...

    The diffuse interstellar band around 8620 Å. II. Kinematics and distance of the DIB carrier
    Context. Diffuse interstellar bands (DIBs) are important interstellar absorption features of which the origin is still debated. With the large data sets from...

    The distribution of sunspot decay rates
    The distribution of sunspot decay rates is studied using the Greenwich Photoheliographic Results (GPR) for a total of approximately hundred years between 1874...

    The diverse cold molecular gas contents, morphologies, and kinematics of type-2 quasars as seen by ALMA
    We present CO(2−1) and adjacent continuum observations of seven nearby radio-quiet type-2 quasars (QSO2s) obtained with ALMA at ∼0.2″ resolution (370 pc at z ∼...
