For the last decade, several probes have pointed to a cosmological tension between the
amplitude of density fluctuations extrapolated from the cosmic microwave background within …

Large-scale structure surveys have reported measurements of the density of matter, Ωm, and
the amplitude of clustering, σ8, that are in tension with the values inferred from observations …

Baryonic Acoustic Oscillation (BAO) data from the Dark Energy Spectroscopic Instrument
(DESI), in combination with Cosmic Microwave Background (CMB) data and Type Ia …

Baryonic feedback is a major systematic in weak lensing cosmology. Its most studied effect
is the suppression of the lensing power spectrum, a second-order statistic, on small scales …

Weak gravitational lensing convergence peaks, the local maxima in weak lensing
convergence maps, have been shown to contain valuable cosmological information …

Context. Mock galaxy catalogues are essential for correctly interpreting current and future
generations of galaxy surveys. Despite their significance in galaxy formation and cosmology …

Observational cosmology is rapidly closing in on a measurement of the sum M ν of neutrino
masses, at least in the simplest cosmologies, while opening the door to probes of non …

Energetic feedback processes associated with accreting supermassive black holes can
expel gas from massive haloes and significantly alter various measures of clustering on …

Recent large-scale structure (LSS) surveys have revealed a persistent tension in the value
of $ S_8 $ compared to predictions from the standard cosmological model. This tension may …

The symmetron is a dark energy and dark matter candidate that forms topological defects in
the late-time universe and holds the promise of resolving some of the cosmological tensions …
