A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

▪ 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 …

We present constraints on cosmological parameters from the Pantheon+ analysis of 1701
light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from z= 0.001 to …

Here we present 1701 light curves of 1550 unique, spectroscopically confirmed Type Ia
supernovae (SNe Ia) that will be used to infer cosmological parameters as part of the …

The cosmological principle (CP)—the notion that the Universe is spatially isotropic and
homogeneous on large scales—underlies a century of progress in cosmology. It is …

Over the past decade, the disparity between the value of the cosmic expansion rate
determined directly from measurements of distance and redshift and that determined instead …

We present a recalibration of the photometric systems in the Pantheon+ sample of Type Ia
supernovae (SNe Ia) including those in the SH0ES distance-ladder measurement of H 0. We …

The tip of the red giant branch (TRGB) provides a luminous standard candle for constructing
distance ladders to measure the Hubble constant. In practice, its measurements via edge …

We present cosmological results from the measurement of baryon acoustic oscillations
(BAO) in galaxy, quasar and Lyman-$\alpha $ forest tracers from the first year of …

We present the full Hubble diagram of photometrically classified Type Ia supernovae (SNe
Ia) from the Dark Energy Survey supernova program (DES-SN). DES-SN discovered more …
