Growth of cosmic structure

D Huterer - The Astronomy and Astrophysics Review, 2023 - Springer
We review one of the most fruitful areas in cosmology today that bridge theory and data—the
temporal growth of large-scale structure. We go over the growth's physical foundations, and …

Evidence for suppression of structure growth in the concordance cosmological model

NM Nguyen, D Huterer, Y Wen - Physical Review Letters, 2023 - APS
We present evidence for a suppressed growth rate of large-scale structure during the dark-
energy-dominated era. Modeling the growth rate of perturbations with the “growth index” γ …

The Pantheon+ analysis: Improving the redshifts and peculiar velocities of Type Ia supernovae used in cosmological analyses

A Carr, TM Davis, D Scolnic, K Said, D Brout… - Publications of the …, 2022 - cambridge.org
We examine the redshifts of a comprehensive set of published Type Ia supernovae, and
provide a combined, improved catalogue with updated redshifts. We improve on the original …

Running vacuum against the H 0 and σ8 tensions

JS Peracaula, A Gómez-Valent… - Europhysics …, 2021 - iopscience.iop.org
The cosmological term, Λ, was introduced 104 years ago by Einstein in his gravitational field
equations. Whether Λ is a rigid quantity or a dynamical variable in cosmology has been a …

galaxies derived from fundamental plane (FP) measurements using data from the Sloan …

The Pantheon+ analysis: evaluating peculiar velocity corrections in cosmological analyses with nearby type Ia supernovae

ER Peterson, WDA Kenworthy, D Scolnic… - The Astrophysical …, 2022 - iopscience.iop.org
Separating the components of redshift due to expansion and peculiar motion in the nearby
universe (z< 0.1) is critical for using Type Ia Supernovae (SNe Ia) to measure the Hubble …

Running Vacuum in the Universe: Phenomenological Status in Light of the Latest Observations, and Its Impact on the σ8 and H0 Tensions
