    The cosmic web from perturbation theory
    Context. Analysing the large-scale structure (LSS) in the Universe with galaxy surveys demands accurate structure formation models. Such models should ideally...

    The COSMOS-Web ring: In-depth characterization of an Einstein ring lensing system at z ∼ 2
    Aims: We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z ≈ 2 that we serendipitously discovered during the data reduction of the...

    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 DART imaging and CaT survey of the Fornax dwarf spheroidal galaxy
    Aims.As part of the DART project we have used the ESO/2.2m Wide Field Imager in conjunction with the VLT/FLAMES GIRAFFE spectrograph to study the detailed...

    The deepest Herschel-PACS far-infrared survey: number counts and infrared luminosity functions from combined PEP/GOODS-H observations
    We present results from the deepest Herschel-Photodetector Array Camera and Spectrometer (PACS) far-infrared blank field extragalactic survey, obtained by...

    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...
