Cosmology intertwined: A review of the particle physics, astrophysics, and cosmology associated with the cosmological tensions and anomalies
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 …

Challenges for ΛCDM: An update
L Perivolaropoulos, F Skara - New Astronomy Reviews, 2022 - Elsevier
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 …

Is the observable Universe consistent with the cosmological principle?
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 …

Observational evidence for cosmological coupling of black holes and its implications for an astrophysical source of dark energy
Observations have found black holes spanning 10 orders of magnitude in mass across most
of cosmic history. The Kerr black hole solution is, however, provisional as its behavior at …

A test of the cosmological principle with quasars
NJ Secrest, S von Hausegger, M Rameez… - The Astrophysical …, 2021 - iopscience.iop.org
We study the large-scale anisotropy of the universe by measuring the dipole in the angular
distribution of a flux-limited, all-sky sample of 1.36 million quasars observed by the Wide …

A short review of loop quantum gravity
A Ashtekar, E Bianchi - Reports on Progress in Physics, 2021 - iopscience.iop.org
An outstanding open issue in our quest for physics beyond Einstein is the unification of
general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading …

Does Hubble tension signal a breakdown in FLRW cosmology?
The tension between early and late Universe probes of the Hubble constant has motivated
various new FLRW cosmologies. Here, we reanalyse the Hubble tension with a recent age …

Probing cosmic isotropy with a new X-ray galaxy cluster sample through the LX–T scaling relation
The isotropy of the late Universe and consequently of the X-ray galaxy cluster scaling
relations is an assumption greatly used in astronomy. However, within the last decade, many …

Evidence for anisotropy of cosmic acceleration
J Colin, R Mohayaee, M Rameez, S Sarkar - Astronomy & Astrophysics, 2019 - aanda.org
Observations reveal a “bulk flow” in the local Universe which is faster and extends to much
larger scales than are expected around a typical observer in the standard ΛCDM cosmology …

Larger values in the CMB dipole direction
Based on the assumption that quasars (QSOs) and gamma-ray bursts (GRBs) represent
standardizable candles, we provide evidence that the Hubble constant H 0 adopts larger …
