Cross-correlation of SPT-3G D1 CMB lensing and DES Y3 galaxy lensing measures S8 = 0.833^{+0.047}_{-0.061} at 14 sigma using polarization-only reconstruction, consistent with Planck and DES Y3.

Forecasts ~thousands of FRB-QSO pairs at <10' separation by 2035 for CGM, cosmic web, and Milky Way halo studies with HST/COS.
LRDs transition from underdense low-halo-mass environments at z>4 to typical galaxy conditions by z~3.5, with halo growth leading to larger sizes and SED changes that explain their disappearance at lower redshifts.
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.
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.
A minimalist analytic extension shows spin-kick alignment in the tug-boat mechanism arises either from fast rotation averaging out perpendicular asymmetries or from spin-aligned mass flux, but the former requires unrealistically high rotation unless magnetic angular-momentum transport is efficient.
Void x CMB lensing from Roman mocks is robust to catalog construction choices and forecasts S/N of 13-31 sigma with Planck, SO, and CMB-S4-like data for 2D and 3D voids.
GRMHD simulations identify magnetic flux through the black hole horizon as the key variable setting jet efficiency and radiative output across MAD, INT, and SANE states, with mappings to temporal classes in GRS 1915+105 and other sources.
A clustering-aware correction algorithm using spatial partitioning and projected gradient descent preserves single-linkage clusters in lossy-compressed particle data while keeping competitive compression ratios.
The authors introduce the Venus Similarity Index (VSI), Ancient Venus Similarity Index (AVSI) and Future Earth Similarity Index (FESI) as geometric-mean metrics to compare exoplanets to Venus-like environments for habitability studies.
The authors introduce analog matching to generate Roman Space Telescope mock catalogs that reproduce emission-line galaxy statistics and highlight the need to match void properties separately from two-point clustering for CMB cross-correlation studies.
Stacking DESI spectra reveals star-formation-driven Mg II outflows from low-mass galaxies that escape dark matter halos, providing indirect evidence that stellar feedback causes baryon deficiency.
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.
SKA-Mid all-sky surveys are projected to detect up to 3500 radio mini-halos at z<1 and enable a complete census of radio-loud BCGs to z~2.
A CPRT formalism is presented as a common platform to link cosmological MHD simulations, theory, and SKA polarized sky data for interpreting magnetic fields across cosmic time.
Population synthesis of pulsar-massive star binaries yields an estimate for the number of observable VHE gamma-ray sources in the Galaxy, incorporating anisotropic wind-interaction zones.
SKA+VLBI will deliver microarcsecond astrometry, polarimetry, and rapid multi-frequency imaging to track jets and accretion in X-ray binaries on AU scales.
