Infrared images of the Q0957+561 gravitational lens obtained with the Hubble Space Telescope show two large (~5") lensed images of the zs=1.41 quasar host...
The Hubble diagram of type Ia supernovae as a function of host galaxy morphology
We present new results on the Hubble diagram of distant type Ia supernovae (SNeIa) segregated according to the type of host galaxy. This makes it possible to...
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...
