    The dark nature of GRB 051022 and its host galaxy
    Aims:We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 h and 1.15 yr after the event. It is the most...

    The density of Abell clusters.
    We present a precise procedure for obtaining predictions of any clustering model for the density of Abell clusters. To this end we use results from the recently...

    The dependence of the gradients of oxygen and nitrogen-to-oxygen on stellar age in MaNGA galaxies
    We derived the oxygen abundance (O/H), the nitrogen-to-oxygen (N/O) abundance ratio, and their corresponding radial gradients for a sample of 1431 galaxies from...

    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...
