Non-Gaussianity from Particle Production during Inflation
Published 2010-01-01“…In this review we show that interactions between the produced particles and the inflaton condensate can lead to a qualitatively new mechanism for generating cosmological fluctuations from inflation. We illustrate this effect using a simple prototype model g2(ϕ−ϕ0)2χ2 for the interaction between the inflaton, ϕ, and iso-inflaton, χ. …”

Geometrical Distances of Extragalactic Binaries through Spectroastrometry
Published 2025-01-01“…The growing “Hubble tension” has prompted the need for precise measurements of cosmological distances. This paper demonstrates a purely geometric approach for determining the distances to extragalactic binaries through a joint analysis of spectroastrometry (SA), radial velocity (RV), and light-curve (LC) observations. …”

Dark QCD perspective inspired by strong CP problem at QCD scale
Published 2025-01-01“…We also briefly address nontrivial cosmological aspects, such as those related to the dark-chiral phase transition, the dark matter production, and an ultraviolet completion related to the ultralight ALP.…”

Dynamical System Analysis of Interacting Hessence Dark Energy in f(T) Gravity
Published 2017-01-01“…Interestingly, the analysis shows that the universe may resemble the “cosmological constant” like evolution (i.e., ΛCDM model is a subset of the solution set). …”

Deviations From μ‐τ Symmetry Using Δ27 Group on Neutrino Masses and Mixings
Published 2024-01-01“…The sum of the three absolute neutrino mass eigenvalues, ∑imi (i=1,2,3), is found to be consistent with the value given by the latest Planck cosmological data, ∑imi<0.12 eV. The model further predicts effective neutrino masses for neutrinoless double beta decay, 4.15 meV≤mee≤30.6 meV; tritium beta decay, 8.4 meV≤mβ≤30.5 meV; Jarlskog invariant, JCP=±0.022 for CP violation; baryon asymmetry YB=1.15×10−10 for normal hierarchical case; and also 49.5 meV≤mee≤51.7 meV, 49.5 meV≤mβ≤51.4 meV, JCP=±0.022, and YB=1.12×10−10 for inverted hierarchical case, respectively.…”

Finding Lensed Radio Sources with the Very Large Array Sky Survey
Published 2025-01-01“…Radio observations of strongly lensed objects are valuable as cosmological probes. Lensed radio sources have proven difficult to identify, in large part due to the limited depth and angular resolution of the previous generation of radio sky surveys, and, as such, only a few dozen lensed radio sources are known. …”

On the Evidence of Dynamical Dark Energy
Published 2024-12-01“…In comparison to the CPL model, the tension with the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mo>Λ</mo></semantics></math></inline-formula>CDM model is reduced for the SSLCPL model, suggesting that the evidence for dynamical dark energy from DESI BAO data is dependent on cosmological models. The inclusion of spatial curvature has little impact on the results in the SSLCPL model.…”

A Universal Break in Energy Functions of Three Hyperactive Repeating Fast Radio Bursts

Baryon Pasting the Uchuu Light-cone Simulation
Published 2025-01-01“…Additionally, scatter in the thermal pressure and gas density profiles of halos enhances the X-ray and SZ power spectra, leading to biases in cosmological parameter estimates. These findings are statistically robust due to the extensive sky coverage and large halo sample in the BP-Uchuu maps. …”

Intrinsic Pulse Widths of FRB 20121102A and Calculation of Broadening from Propagation and Instrumental Effects
Published 2025-01-01“…At a redshift of 0.193, the pulse width is broadened by a factor of approximately 0.16 due to cosmological time dilation. It is found that the instrumental broadening only contributes a fraction of 10 ^−3 –10 ^−1 to the observed pulse width. …”
