Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

Abstract The GLASS-JWST Early Release Science (hereafter GLASS-JWST-ERS) Program
will obtain and make publicly available the deepest extragalactic data of the ERS campaign …

The gravitationally lensed supernova Refsdal appeared in multiple images produced
through gravitational lensing by a massive foreground galaxy cluster. After the supernova …

A Kavli Institute for Theoretical Physics workshop in July 2019 directed attention to the
Hubble constant discrepancy. New results showed that it does not appear to depend on the …

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 …

We present a new parametric lens model for the massive galaxy cluster Abell 2744 based
on new ultra-deep JWST imaging taken in the framework of the UNCOVER program. These …

Multiply imaged time-variable sources can be used to measure absolute distances as a
function of redshifts and thus determine cosmological parameters, chiefly the Hubble …

The Hubble constant (H 0) measures the current expansion rate of the Universe, and plays a
fundamental role in cosmology. Tremendous effort has been dedicated over the past …

The current standard model of cosmology successfully describes a variety of measurements,
but the nature of its main ingredients, dark matter and dark energy, remains unknown. is a …
