A fibre-bundle model with dual spacetimes (smooth manifold plus causal set) derives relative locality in general PQG theories without requiring momentum-space curvature.
Cross-correlation of SPT-3G CMB lensing and DES Y3 galaxy lensing measured at 14 sigma significance yields S8 = 0.833 +0.047 -0.061, consistent with Planck and DES Y3 shear-only results.
Amortized neural posterior estimation reproduces nested sampling constraints on RMF couplings for neutron-star EOS with no bias and generates 30,000 samples in 2.5 seconds.
ANTARES Galactic Ridge upper limits yield competitive dark-matter annihilation/decay bounds, the first neutrino-based branon constraints, and a negative KM3NeT forecast for the thermal relic cross-section.
The authors define a locality condition for hard-mode states during inflation that unifies local effective dynamics for soft modes, suppression of loop corrections, generalized soft theorems, and absence of infrared divergences in observable correlators.
Leptophilic ALPs with m_a > f_a can explain the electron anomalous magnetic moment tension over a large parameter space and are testable via μ→e conversion.
Extended misalignment for axion-like particles with constant-ω_ϕ pre-oscillation and dark radiation coupling yields data-driven constraints favoring negative ω_ϕ and f_ϕ in [80, 1.5×10^10] TeV but does not ease cosmological tensions.
Spectral features of primordial gravitational-wave backgrounds can directly reconstruct the mass and decay rate of long-lived BSM particles via the frequencies imprinted by an early matter-dominated epoch.
kSZ measurements constrain the gravitational acceleration between galaxy halos to follow g ∝ 1/r^{2.1±0.3}, consistent with Newtonian gravity in ΛCDM.
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.
SN peculiar velocities combined with Planck CMB yield simultaneous constraints on σ8, γ and Ωk, with ~2σ preference for positive curvature and GR-consistent growth.
A relativistic self-interacting dark-matter fluid near a critical sound speed gives a universal Bondi accretion rate that can grow 10-solar-mass seed black holes into 10^9–10^10 solar-mass supermassive black holes by z≈7.
SPT-3G delivers the most precise CMB EE and TE spectra at high multipoles to date, giving LCDM parameters with H0 = 66.66 ± 0.60 km/s/Mpc from ground-based data alone and reaching Planck-level constraints when combined with ACT.
Accelerating scaling attractors without dark energy appear only when the interaction is controlled by DM density and energy flows from DM to a barotropic fluid.
Torsion-induced one-loop corrections can suppress the stochastic gravitational wave signal from inflaton decay by up to two orders of magnitude relative to tree-level predictions.
Positive tidal charge reduces Blandford-Znajek power by up to 15.2% while negative tidal charge increases it by up to 66.5% compared to Kerr black holes of equal mass and angular velocity.
The paper derives leading-order de Sitter corrections of order Lambda to gravitational wave displacement and spin memory using an adapted Bondi-Sachs framework.
A modular A4 framework generates Dirac neutrino masses naturally, reproduces the charged lepton hierarchy, and predicts neutrino mixing angles, mass differences, maximal CP violation, and a cosmologically allowed neutrino mass sum.
CMB-only data give f_EDE < 0.07 at 95% CL with no strong AEDE signal, while CMB+DESI yields f_EDE = 0.055^{+0.024}_{-0.047} at 68% CL and lowers Hubble tension to 2.6 sigma.
Spatial entropy can fall as webs form while phase-space entropy rises; anisotropy is cast as a free-energy order parameter that activates earlier for nonlocal tidal operators than for local curvature.
EasyScan_HEP 2 adds AI-agent interfaces to a HEP parameter scan framework for natural-language to .ini config translation and new sampler integration.
Two minimal single-parameter extensions of the α-Starobinsky model shift ns into the 1σ ACT DR6 region while keeping r < 0.038 and yielding T_re ~ 10^9 GeV for N_k in [50,65].
For a rotating black hole in a Dehnen dark matter halo, the scalar quasibound spectrum is the Kerr hydrogenic spectrum with a halo-shifted effective mass, and the superradiant window narrows through a halo-modified horizon quantity.
