First joint 2PCF+3PCF full-shape analysis on BOSS DR12 real data improves σ(h) by ~29%, σ(ω_cdm) by ~10%, and σ(A_s) by ~24% over 2PCF alone via extra BAO information in 3PCF triangles.
JWST/NIRCam imaging and Keck/MOSDEF spectroscopy identify COSMOS-74706 as an unlensed barred spiral galaxy at z_spec=3.159, with the bar confirmed via residuals, ellipse fitting, and Fourier modes.
A 4.46 solar-mass black hole is found in a 94-year eccentric orbit with a main-sequence turnoff star in ω Centauri via 23-year astrometric monitoring.
Detection of a variable stratified UFO with velocities 0.1c and 0.3c, extreme mass outflow rates, and kinetic powers of 1-10% of bolometric luminosity in quasar WISSH13 at z=3.294.
3D GRMHD collapsar simulations initialized with toroidal fields demonstrate that an accretion-disk dynamo generates poloidal fields and launches variable, wobbling jets with LGRB-comparable power.
SOFIA observations provide the first experimental magnetic-dipole hyperfine constants for [13C II] and refined centroid frequency using astronomical data.
TopoFisher optimizes trainable filtrations, vectorizations, and compressors in persistent homology to maximize Fisher information, yielding higher information than fixed cosmological summaries and approaching neural baselines with far fewer parameters while generalizing better under simulator shifts
Methyl carbamate is detected for the first time in interstellar space toward G358.93-0.03 MM1, with a column density of (4.21±0.84)×10^15 cm^{-2} at 204 K, while glycine and other C2H5O2N isomers remain undetected.
JWST and ALMA data provide the earliest direct evidence of ram-pressure stripping in a post-starburst galaxy at z=3.06, implying the process can quench star formation in nascent groups at z>3.
Tilted supercritical accretion disks around black holes can accrete mass at rates up to ten times the Eddington limit due to standing shocks, unlike untilted disks that respect the limit.
Self-consistent simulations reveal that reverse shocks in GRB photospheres stay radiation-mediated down to optical depths of a few tenths, with photons decoupling over a broad radial range and forming a quasi-thermal post-cursor.
First public GPU-accelerated pulse-profile modeling code for X-ray millisecond pulsars that delivers 10^3–10^4 speedups to 2–5 ms per evaluation at 10^{-3} relative accuracy and removes an interpolation bias in atmosphere tables.
The eRASS1 data release catalogs nearly 930,000 X-ray sources from the first six months of the eROSITA survey, increasing known sources by over 60% and resolving 20% of the 1-2 keV cosmic X-ray background.
X-ray reverberation lags are used to measure the mass of the stellar-mass black hole Cygnus X-1 for the first time.
Spatially resolved spectroscopy shows SDSS1335+0728 has a three-zone ionisation structure, optically thin dust, and sustained low-level nuclear activity for at least 1500 years, implying the Ansky event is a faint transient in an already accreting low-mass SMBH.
Relativistic single-particle scattering cross sections for strong electromagnetic waves in strongly magnetized plasma are computed for arbitrary polarization and angle, showing strong suppression and sub-unity optical depth for quasi-parallel propagation.
A new RTU grid method models the lensing source as a Gaussian process on a ray-transformed uniform grid, achieving comparable fits with roughly half the pixels per dimension and higher ELBOs on mock data.
Stacking of DESI quasar spectra reveals strong, localized Hα emission aligned with radio jet axes around radio galaxies, indicating anisotropic jet-CGM interaction.

No evidence of vorticity production from initially irrotational turbulent gravitational collapse
Direct numerical simulations find no vorticity generation attributable to the collapse flow itself when starting from irrotational turbulence in a barotropic, non-magnetized fluid.
