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

Elcio Abdalla et al.

Summary: The paper discusses the limitations of the standard Lambda Cold Dark Matter (Lambda CDM) cosmological model and proposes new physics models to alleviate the tensions in various cosmological measurements. The authors emphasize the importance of considering a wide range of data and discuss the significance of upcoming experiments and space missions in addressing open questions in cosmology.

Larger H0 values in the CMB dipole direction

Orlando Luongo et al.

Summary: Based on the assumption that quasars and gamma-ray bursts can be used as standard candles, the study found evidence that the Hubble constant adopts larger values in hemispheres aligned with the cosmic microwave background dipole direction. This trend suggests a departure from the current cosmological models. The findings are consistent with reported variations in other cosmological measurements.

Hints of FLRW breakdown from supernovae

Chethan Krishnan et al.

Summary: This study explores the correlation between higher H-0 and the CMB dipole direction based on the angular distribution of type Ia supernovae in the Pantheon compilation. It suggests the possibility of probing anisotropic Hubble expansions and provides concrete predictions for future inferences of H-0.

A combined analysis of the H0 late time direct measurements and the impact on the Dark Energy sector

Eleonora Di Valentino

Summary: The study combines multiple measurements of the Hubble constant, resulting in an optimistic estimate of H-0 = 72.94 +/- 0.75 km s(-1) Mpc(-1), significantly different from the ACDM model. The research also highlights various new phenomena that emerge in different dark energy cosmological models, such as phantom dark energy and coupling between dark matter and dark energy.

Snowmass2021-Letter of interest cosmology intertwined II: The hubble constant tension

Eleonora Di Valentino et al.

Summary: Current cosmological probes have confirmed the standard A Cold Dark Matter cosmological model with unprecedented accuracy, but tensions between different independent cosmological datasets have emerged. These tensions may indicate issues with the standard cosmological scenario and the potential need for new physics.

In the realm of the Hubble tension-a review of solutions *

Eleonora Di Valentino et al.

Summary: There are significant discrepancies in predictions of the Hubble constant, leading to various proposed solutions including new physics theories or modifications to existing cosmological models. Some solutions successfully reduce tension and improve agreement with data, while many others fail to do so, highlighting the need for further research and evidence.

A Test of the Cosmological Principle with Quasars

Nathan J. Secrest et al.

Summary: The study reveals that the direction of the dipole in the quasar sky is similar to that of the cosmic microwave background (CMB), but its amplitude is over twice as large as expected, rejecting the canonical interpretation of the CMB dipole. This conflicts with the cosmological principle, a foundational assumption of the concordance ΛCDM model.
