The cosmic expansion history tests the dynamics of the global evolution of the universe and its energy density contents, while the cosmic growth history tests the evolution of the inhomogeneous part of the energy density. Precision comparison of the two histories can distinguish the nature of the physics responsible for the accelerating cosmic expansion: an additional smooth component - dark energy - or a modification of the gravitational field equations. With the aid of a new fitting formula for linear perturbation growth accurate to 0.05-0.2%, we separate out the growth dependence on the expansion history and introduce a new growth index parameter \gamma that quantifies the gravitational modification.

AGN Line-Intensity Mapping: A Probe of Faint Black Holes at Cosmic Noon
Forecasts indicate [Ne V] LIM cross-correlations can constrain mean AGN intensity and bias at cosmic noon with sensitivity to sources fainter than 5 sigma thresholds.

Impact and measurability of linear relativistic effects in galaxy surveys
Neglecting linear GR effects biases f_NL at 1–3σ for Euclid/SPHEREx in SFB forecasts; multi-tracer improves Doppler detection and weakly breaks b_ϕ f_NL degeneracy.

The dark matter halo mass function in the $\Lambda\mathrm{CDM}$ cosmology at all times and over all scales -- from planetary to galaxy cluster masses
A Reed-based fitting formula for the ΛCDM halo mass function, accurate to a few percent from 10^{-6} to 10^{15.5} M_⊙ and z=0–30, obtained via nested VVV simulations plus a new subsampling reconstruction.

Evidence for deviation in gravitational light deflection from general relativity at cosmological scales with KiDS-Legacy and CMB lensing
KiDS-Legacy weak lensing plus CMB data yields a 3 sigma deviation in light deflection from GR in a Lambda CDM background, with the signal driven by large-scale CMB lensing amplitudes.

Modeling and measuring the anisotropic halo 3-point correlation function: a coordinated study
Novel implementation of anisotropic 3PCF model and estimator tested on 298 halo catalogs shows degeneracy breaking between f and b1 in 3PCF-only analysis but limited added value in joint 2PCF+3PCF due to tree-level mo...

Searching for signatures of inflationary massive fields in DESI Imaging data and Stage-V galaxy surveys
DESI Imaging yields no robust beyond-local PNG detection, while Stage-V LBG forecasts give σ(Δ)≈0.17–0.50 near the local limit for f_NL,Δ^fid=4 and an empirical link to σ(f_NL^loc).

ZTF SN Ia DR2 follow-up: early excess in Type Ia supernova light curves
Up to about a quarter of Type Ia supernovae may have an early light-curve bump, but the candidate list depends strongly on the detection method and neither leading explosion model is clearly preferred.

Impact of inhomogeneous curvature on growth rate measurements from magnitude fluctuations
Full-GR simulations find that inhomogeneous curvature produces only sub-dominant systematic offsets in growth-rate measurements from magnitude fluctuations at z ≲ 0.2 relative to current statistical errors.

Information Content of the Cosmic Web
The paper defines a continuous Shannon entropy from the tidal tensor eigenvalue sign patterns of the cosmic web and shows that its redshift evolution constrains the linear growth rate f(z) complementary to redshift-sp...

Hubble Tension as an Effect of Horizon Entanglement Nonequilibrium
A phenomenological 'horizon entanglement deficit' with the form ρ ∝ H² is fit to low-z data under a forced H0=73 prior; the nonzero amplitude is a restatement of that prior.

Forecasting the E_G measurements from the photometric and spectroscopic surveys of Chinese Space Station Survey Telescope (CSST)
CSST forecasts E_G to 3–9% over 0<z<1.2, with the modified-gravity parameter Σ0 constrained to ~5% if β errors follow an assumed external forecast.

Teleparallel dark energy in a nonflat universe
Nonflat teleparallel dark energy with a vanishing potential is statistically favored over Lambda CDM in the authors' MCMC fit and mildly prefers an open universe.

Little ado about everything II: an `emergent' dark energy from structure formation to rule cosmic tensions
An ensemble-averaged stochastic cosmology with a 'little ado' noise term produces an emergent dark energy that fits late-time data and claims to relieve the H0 and f sigma8 tensions.
