    The Cosmic Evolution of Quasar Host Galaxies
    We present the results of a near-infrared imaging study of the host galaxies of 17 quasars in the redshift range 1 RLQ(host)=-27.55+/-0.12 and K>RLQ(host)=-26...

    The cosmic web connection to the dark matter halo distribution through gravity
    This work investigates the connection between the cosmic web and the halo distribution through the gravitational potential at the field level. We combine three...

    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 curious activity in the nucleus of NGC 4151: jet interaction causing variability?
    A key characteristic of many active galactic nuclei (AGNs) is their variability, but its origin is poorly understood, especially in the radio domain. Williams...

    The Dark Energy Survey Year 3 and eBOSS: constraining galaxy intrinsic alignments across luminosity and colour space
    We present direct constraints on galaxy intrinsic alignments (IAs) using the Dark Energy Survey Year 3 (DES Y3), the Extended Baryon Oscillation Spectroscopic...

    The Dark Energy Survey Year 3 high-redshift sample: selection, characterization, and analysis of galaxy clustering
    The fiducial cosmological analyses of imaging surveys like DES typically probe the Universe at redshifts z < 1. We present the selection and characterization of...

    The dark side of galaxy stellar populations - I. The stellar-to-halo mass relation and the velocity dispersion-halo mass relation
    The growth and properties of galaxies are thought to be closely connected to the ones of their host dark matter haloes. Despite the importance of this so-called...

    The dark side of galaxy stellar populations - II. The dependence of star-formation histories on halo mass and on the scatter of the main sequence
    Nearby galaxies are the end result of their cosmological evolution, which is predicted to be influenced by the growth of their host dark matter haloes. This co...

    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...
