    HARMONI view of the host galaxies of active galactic nuclei around cosmic noon. Resolved stellar morpho-kinematics and the M<SUB>BH</SUB> − σ<SUB>⋆</SUB> relation
    Context. The formation and evolution of galaxies appear linked to the growth of supermassive black holes, as evidenced by empirical scaling relations in nearby...

    HerMES: Far infrared properties of known AGN in the HerMES fields
    Nuclear and starburst activity are known to often occur concomitantly. Herschel-SPIRE provides sampling of the far-infrared (FIR) spectral energy distributions...
  • Publication
    Herschel ATLAS: The cosmic star formation history of quasar host galaxies
    We present a derivation of the star formation rate per comoving volume of quasar host galaxies, derived from stacking analyses of far-infrared to mm-wave...

    Herschel-ATLAS: Blazars in the science demonstration phase field
    To investigate the poorly constrained sub-mm counts and spectral properties of blazars we searched for these in the Herschel-ATLAS (H-ATLAS) science...

    High Frequency Peakers: The faint sample
    We present a sample of sources with convex radio spectra peaking at frequencies above a few GHz, known as ``High Frequency Peakers" (HFPs). A ``bright" sample...

    High z Radio-Loud and Radio-Quiet QSO Environments
    We propose a systematic study of the environments of a representative sample of Radio Loud Quasars (RLQ) and Radio Quiet Quasars (RQQ) in two different redshift...

    High-quality Extragalactic Legacy-field Monitoring (HELM) with DECam: Project Overview and First Data Release
    High-quality Extragalactic Legacy-field Monitoring (HELM) is a long-term observing program that photometrically monitors several well-studied extragalactic...

    HST confirmation of the lensed quasar J03.13.
    In order to definitely prove the claim by Claeskens et al. (1996A&A...305L...9C) that J03.13 is a doubly imaged quasar, WFPC2 direct imaging and FOS...

    Identification of quasi-stellar objects in the IRAS catalogue
    The authors have studied the IRAS extragalactic catalogue (Lonsdale et al., 1985), with the aim of reliably identifying quasi-stellar objects. Using the best...
