Background-inert modified-gravity couplings create a σ80–λ degeneracy under compressed CMB priors, inflating σ80 and producing spurious model preference, which an implied-A_s diagnostic exposes.
New simulations show that cross-correlating gravitational wave background anisotropies with galaxy distributions can enable discovery at angular scales of 4-6 degrees with next-generation observatories.
No CMB-consistent CPL dark energy model can simultaneously fit both the BAOtr and DESI datasets; the 3.7-sigma disagreement at z=0.51 sets an irreducible floor.
ACT DR6 CMB lensing map gives σ8 = 0.819 ± 0.015 and H0 = 68.3 ± 1.1 km/s/Mpc, consistent with Planck ΛCDM but 1.7-2.1σ higher in S8 than KiDS, DES, and HSC galaxy surveys.
DESI's instrumentation, including a 3.2-degree prime-focus corrector, 5020 fiber positioners across ten petals, and ten three-channel spectrographs, has been successfully installed and meets all performance goals for a five-year survey of 40 million galaxies and quasars.
An automated telescope simulator test stand is built and initially tested to characterize robotic fiber positioners for stability under varying gravity vectors, targeting 1 μm position, 5 μm focus, and 0.4° tilt performance.
Re-expressing the Hubble tension via posterior-implied E(z) histories yields moderate mismatches (S_hist of 1.65 and 2.55) that correspond to only 1.1-2.1 sigma equivalents, below the usual 4.9 sigma scalar-H0 discrepancy.
Non-conserved biased tracers debias more rapidly than conserved tracers, leading to time-dependent suppression of large-scale power.
Calibration uncertainties during supernova light-curve fitting cause roughly 50% degradation in dark energy figure of merit for Stage IV surveys, dominating over 13% degradation from model training errors and showing near-degeneracy with cosmology.
New CAMELS simulations in larger (50 Mpc/h)^3 boxes with 35 varied parameters produce tighter neural-network constraints on model parameters than prior smaller-volume runs, with public data release.
K-essence cosmology induces a redshift-dependent effective mass on gravitational waves, causing phase shifts that link scalar field dynamics to GW observables without changing wave speed or luminosity distance.
MUST is a new 6.5 m telescope designed to deliver simultaneous optical spectra for over 20,000 targets across a 5 deg² field, enabling the largest 3D spectroscopic map of the Universe with redshifts for more than 100 million objects over an 8-year survey.
Forecasts show that ~66 optical GRBs can achieve σ_w ≈ 0.47 in wCDM using Dainotti relations, matching Planck precision and enabling independent high-redshift tests of dark energy.
KiDS-Legacy cosmic shear plus external probes yields S8 = 0.816 ± 0.006 in Lambda-CDM and consistent bounds on w0, wa, sum m_nu and Omega_K with no strong preference for extensions.
Extended analysis of DESI DR2 data confirms robust evidence for dynamical dark energy with phantom crossing preference, stable under parametric and non-parametric modeling.
A spinor-field Modified Chaplygin Gas model in Kantowski-Sachs spacetime yields H0 of 67-68 km/s/Mpc, late-time isotropy, q0 of -0.49, and a better AIC fit than LambdaCDM.
A review summarizing direct and auxiliary large-scale structure probes for constraining dark energy and demonstrating their combined precision and accuracy.
