    The Hubble Space Telescope Survey of BL Lacertae Objects: Gravitational Lens Candidates and Other Unusual Sources
    We present Hubble Space Telescope (HST) observations of seven unusual objects from the HST ``snapshot survey'' of BL Lacertae objects, of which four are...

    The Hubble tension survey: A statistical analysis of the 2012-2022 measurements
    In order to investigate the potential Hubble tension, we compile a catalogue of 216 measurements of the Hubble-Lemaître constant H 0 between 2012 and 2022...

    The hydrostatic-to-lensing mass bias from resolved X-ray and optical-IR data
    An accurate reconstruction of galaxy cluster masses is key to use this population of objects as a cosmological probe. In this work we present a study on the...

    The impact of baryons on the spins and shapes of dark matter haloes
    We use numerical simulations to investigate how the statistical properties of dark matter (DM) haloes are affected by the baryonic processes associated with...

    The impact of different physical processes on the statistics of Lyman-limit and damped Lyman α absorbers
    We compute the z = 3 neutral hydrogen column density distribution function f(NHI) for 19 simulations drawn from the Overwhelmingly Large Simulations project...

    The Impact of Evolving Infrared Spectral Energy Distributions of Galaxies on Star Formation Rate Estimates
    We combine Herschel-Photodetector Array Camera and Spectrometer (PACS) data from the PACS Evolutionary Probe (PEP) program with Spitzer 24 μm and 16 μm...

    The impact of galaxy formation on the total mass, mass profile and abundance of haloes
    We use cosmological hydrodynamical simulations to investigate how the inclusion of physical processes relevant to galaxy formation (star formation, metal-line...

    The imprint of cosmological hydrogen recombination lines on the power spectrum of the CMB
    We explore the imprint of the cosmological hydrogen recombination lines on the power spectrum of the cosmic microwave background (CMB). In particular, we focus...

    The Influence of Gravitational Microlensing on the Broad Emission Lines of Quasars
    We discuss the effects of microlensing on the broad emission lines (BELs) of QSOs in the light of recent determinations of the size of the broad-line region...
