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 …

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 …

Dipole cosmology: the Copernican paradigm beyond FLRW
C Krishnan, R Mondol… - Journal of Cosmology …, 2023 - iopscience.iop.org
We introduce the dipole cosmological principle, the idea that the Universe is a maximally
Copernican cosmology, compatible with a cosmic flow. It serves as the most symmetric …

Inference of the cosmic rest-frame from supernovae Ia
N Horstmann, Y Pietschke, DJ Schwarz - Astronomy & Astrophysics, 2022 - aanda.org
We determine the proper motion of the Solar System from the Pantheon sample of type Ia
supernovae (SNe). The posterior distribution of the Solar System proper velocity, its …

The dipole of the Pantheon+ SH0ES data
In this paper we determine the dipole in the distance redshift relation from the Pantheon+
data. We find that, while its amplitude roughly agrees with the dipole found in the cosmic …

A new way to test the Cosmological Principle: measuring our peculiar velocity and the large-scale anisotropy independently
We present a novel approach to disentangle two key contributions to the largest-scale
anisotropy of the galaxy distribution:(i) the intrinsic dipole due to clustering and anisotropic …

Galaxy number-count dipole and superhorizon fluctuations
In view of the growing tension between the dipole anisotropy of number counts of
cosmologically distant sources and of the cosmic microwave background (CMB), we …

Consistency of Pantheon+ supernovae with a large-scale isotropic universe
L Tang, HN Lin, L Liu, X Li - Chinese Physics C, 2023 - iopscience.iop.org
We investigate the possible anisotropy of the universe using data on the most up-to-date
type Ia supernovae, ie., the Pantheon+ compilation. We fit the full Pantheon+ data with the …

Aberration of gravitational waveforms by peculiar velocity
One key prediction of General Relativity is that gravitational waves are emitted with two
independent polarizations. Any observation of extra polarization mode, spin-1 or spin-0, is …
