    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...
  • Publication
    The DES view of the Eridanus supervoid and the CMB cold spot
    The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an...
