Modified gravity and cosmology

EN Saridakis, R Lazkoz, V Salzano, PV Moniz… - 2021 - Springer
The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

Review of recent progress in unassisted photoelectrochemical water splitting: from material modification to configuration design

P Peerakiatkhajohn, JH Yun, S Wang… - Journal of Photonics …, 2017 - spiedigitallibrary.org
Photoelectrochemical (PEC) energy conversion systems have been considered as a highly
potential strategy for clean solar fuel production, simultaneously addressing the energy 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 …

S Joudaki, C Blake, A Johnson, A Amon… - Monthly Notices of …, 2018 - academic.oup.com
We perform a combined analysis of cosmic shear tomography, galaxy–galaxy lensing
tomography, and redshift-space multipole power spectra (monopole and quadrupole) using …

tension, phantom dark energy, and cosmological parameter degeneracies

G Alestas, L Kazantzidis, L Perivolaropoulos - Physical Review D, 2020 - APS
Phantom dark energy (w<-1) can produce amplified cosmic acceleration at late times, thus
increasing the value of H 0 favored by CMB data and releasing the tension with local …

Rapid transition of at as a possible solution of the Hubble and growth tensions

V Marra, L Perivolaropoulos - Physical Review D, 2021 - APS
The mismatch in the value of the Hubble constant from low-and high-redshift observations
may be recast as a discrepancy between the low-and high-redshift determinations of the …

Evolution of the tension with the determination and implications for modified gravity theories

L Kazantzidis, L Perivolaropoulos - Physical Review D, 2018 - APS
We construct an updated extended compilation of distinct (but possibly correlated) f σ 8 (z)
redshift space distortion (RSD) data published between 2006 and 2018. It consists of 63 …

KiDS-450: Testing extensions to the standard cosmological model

S Joudaki, A Mead, C Blake, A Choi… - Monthly Notices of …, 2017 - academic.oup.com
We test extensions to the standard cosmological model with weak gravitational lensing
tomography using 450 deg2 of imaging data from the Kilo Degree Survey (KiDS). In these …

Late-time approaches to the Hubble tension deforming H(z), worsen the growth tension

G Alestas, L Perivolaropoulos - Monthly Notices of the Royal …, 2021 - academic.oup.com
Many late-time approaches for the solution of the Hubble tension use late time smooth
deformations of the Hubble expansion rate H (z) of the Planck18/ΛCDM best fit to match the …
