▪ The Hubble parameter, H 0, is not an univocally defined quantity: It relates redshifts to
distances in the near Universe, but it is also a key parameter of the ΛCDM standard …

Abstract Neutrinos are the Standard Model (SM) particles which we understand the least,
often due to how weakly they interact with the other SM particles. Beyond this, very little is …

Measurement of the distances to nearby galaxies has improved rapidly in recent decades.
The ever-present challenge is to reduce systematic effects, especially as greater distances …

We present a measurement of the Hubble constant (H 0) and other cosmological parameters
from a joint analysis of six gravitationally lensed quasars with measured time delays. All …

This paper investigates whether changes to late-time physics can resolve the 'Hubble
tension'. It is argued that many of the claims in the literature favouring such solutions are …

Measurements of the Hubble constant and, more generally, measurements of the expansion
rate and distances over the interval 0< z< 1 appear to be inconsistent with the predictions of …

Weak galaxy lensing surveys have consistently reported a lower amplitude for the matter
fluctuation spectrum, as measured by the S 8 parameter, than expected in the ΛCDM …

We present an improved determination of the Hubble constant from Hubble Space
Telescope (HST) observations of 70 long-period Cepheids in the Large Magellanic Cloud …

The tip of the red giant branch (TRGB) method provides one of the most accurate and
precise means of measuring the distances to nearby galaxies. Here we present a multi …
