Do you smell something decaying? Updated linear constraints on decaying dark matter scenarios

S. Alvi et al.

Summary: The stability of particles in the cosmic soup can affect cosmic evolution. This work updates the constraints on the decaying cold dark matter scenario in the presence of effectively massless decay products. The study finds the most stringent upper limit on the decay rate of decaying cold dark matter particles to be Gamma(DCDM) < 0.129x10(-18) s(-1) (or tau(DCDM) > 246 Gyr) at 95% confidence level, using data from various cosmological probes.

Challenges for ACDM: An update

L. Perivolaropoulos et al.

Summary: In recent years, challenges to the standard ACDM model have been emerging as cosmological observations improve. This review discusses various signals in cosmological and astrophysical data that are in tension with the standard ACDM model, such as the Hubble tension, growth tension, and lensing amplitude anomaly, as well as other less-discussed signals that may hint towards new physics. The goal is to provide an update on the current status of these signals, particularly the Hubble tension, and refer readers to additional resources for more details.

A Uniform Type Ia Supernova Distance Ladder with the Zwicky Transient Facility: Absolute Calibration Based on the Tip of the Red Giant Branch Method

Suhail Dhawan et al.

Summary: In this paper, a uniform distance ladder method is proposed to reduce systematic uncertainties in local measurements by combining Type Ia supernovae (SNe Ia) observed by the Zwicky Transient Facility (ZTF) with a tip of the red giant branch (TRGB) calibration. Results from a pilot study using this method show a measurement of H (0) = 76.94 +/- 6.4 km s(-1) Mpc(-1), and the prospects of extending this distance ladder method using the James Webb Space Telescope are presented.

A Comprehensive Measurement of the Local Value of the Hubble Constant with 1 km s-1 Mpc-1 Uncertainty from the Hubble Space Telescope and the SH0ES Team

Adam G. Riess et al.

Summary: This study reports observations of Cepheid variables in the host galaxies of 42 Type Ia supernovae (SNe Ia) using the Hubble Space Telescope (HST) to calibrate the Hubble constant (H (0)). The observations were collected over four decades and significantly improved the precision of the direct determination of H (0). The study presented multiple verifications of Cepheid photometry and explored different analysis variants to assess the sensitivity of H (0) determination. The baseline result for H (0) was found to be 73.04 +/- 1.04 km s(-1) Mpc(-1).

Cosmological implications of ns ≈ 1 in light of the Hubble tension

Fuminobu Takahashi et al.

Summary: The recent report emphasizes the presence of Hubble tension and explores the impact of various cosmological models on this issue. Some models may have a scalar spectral index greater than the predicted value by ACDM, and even allow for a scale-invariant scenario. Therefore, studying special early Universe models is crucial for understanding this unusual n(s).

Toward inflation with ns=1 in light of the Hubble tension and implications for primordial gravitational waves

Gen Ye et al.

Summary: Recent findings suggest that resolving the Hubble tension completely could indicate a scale-invariant spectrum of primordial scalar perturbation with n(s) = 1 for H-0 around 73 km/s/Mpc. The study shows that for well-known slow-roll models, if inflation ends by a waterfall instability while still in a deep slow-roll region, ns can be lifted to n(s) = 1.

D-term inflation in braneworld models: Consistency with cosmic-string bounds and early-time Hubble tension resolving models

Chia -Min Lin

Summary: In this paper, we revisit D-term inflation and provide bounds on the cosmic string tension using gravitational wave observations. We also consider the possible deviation of the spectral index compared with the ΛCDM model in light of prerecombination resolutions of the Hubble tension. Our study shows that D-term inflation requires very small coupling constants under these constraints, and we demonstrate that natural coupling constants (g = A = 0.1) can be achieved in the case of D-term inflation on the brane.

Summary: The QCD axion is a strong candidate for explaining the abundance of dark matter in the universe. DMRadio-m3 is a next-generation search device designed to detect axion dark matter using sensitive readout circuits and a strong magnetic field. Its primary goal is to achieve high sensitivity in detecting QCD axion dark matter.

Power-law inflation satisfies Penrose's Weyl curvature hypothesis

Summary: The article discusses the relationship between Penrose's views on the origin of the universe and inflation theory, arguing that they are actually consistent. Using the example of power law inflation, it is shown that the initial singularity conditions meet Penrose's criteria and break T-reversal, determining the arrow of time.

Constraining decaying dark matter with BOSS data and the effective field theory of large-scale structures

Theo Simon et al.

Summary: In this study, we updated the cosmological constraints on two decaying dark matter models using BOSS-DR12 data and the EFTofLSS framework. The results showed that Planck data contributed the most to these constraints, and EFTofBOSS data significantly improved the constraints on the lifetime of decayed dark matter. Furthermore, we found that adjusting S-8 to match KiDS-1000 required a longer lifetime and a larger kick velocity.

A Step in understanding the Hubble tension

Daniel Aloni et al.

Summary: As cosmological data have improved, tensions have arisen, particularly regarding the difference between the locally measured Hubble constant H0 and the value inferred from the cosmic microwave background. Interacting radiation has been suggested as a solution, but conventional models are precluded by high polarization CMB data. It is possible that related models that distinguish between high- and low-multipole interactions may provide a solution.

Nonthermally trapped inflation by tachyonic dark photon production

Naoya Kitajima et al.

Summary: This paper discusses late-time inflation driven by a trapped dark Higgs field charged under a U(1)H gauge symmetry, when dark photons are produced through tachyonic preheating. The trapped dark Higgs can decay into massive dark photons, which further decay into SM particles. The study finds that a large portion of the viable parameter space is within the future experimental searches for the dark photon.

The Hubble Constant from Infrared Surface Brightness Fluctuation Distances*

John P. Blakeslee et al.

Summary: A measurement of the Hubble constant H (0) was presented using surface brightness fluctuation distances for 63 bright, mainly early-type galaxies out to 100 Mpc. The result derived from a weighted average of Cepheid and TRGB calibrations is H (0) = 73.3 +/- 0.7 +/- 2.4 km s(-1) Mpc(-1), consistent with recent measurements from other methods. Systematic uncertainties could be reduced below 2% by calibrating the SBF method with precise TRGB distances for a statistical sample of massive early-type galaxies.

Particle production from oscillating scalar field and consistency of Boltzmann equation

Takeo Moroi et al.

Summary: The Boltzmann equation is important in particle cosmology for studying the evolution of distribution functions of particles. In the case of the decay of a scalar condensation, the system may not be well described by the Boltzmann equation when the occupation number of particles becomes large. By comparing quantum field theory calculations and Boltzmann equation results, non-agreements were found, particularly in the expanding Universe.

Why reducing the cosmic sound horizon alone can not fully resolve the Hubble tension

Karsten Jedamzik et al.

Summary: The Hubble tension, a discrepancy between the locally measured expansion rate of the universe and that inferred from the cosmic microwave background measurements, has become a pressing issue in cosmology. Various modifications to the ΛCDM model have been proposed to address this tension, but models that only reduce the sound horizon r(*) cannot fully resolve the issue while remaining consistent with other cosmological datasets.

Consistency tests of ΛCDM from the early integrated Sachs-Wolfe effect: Implications for early-time new physics and the Hubble tension

Sunny Vagnozzi

Summary: New physics increasing the expansion rate before recombination is a possible solution to the Hubble tension, but there is currently no clear evidence for it in the CMB. General consistency tests of the ΛCDM model show that it fits CMB data well, posing a challenge for early-time new physics models.
