A W-Net deep learning model detects asteroids in TESS data independently of trajectory by rotating training image cubes and using adaptive normalization for data scaling.
Using 1000 mock realizations matched to the ASPIRE survey, the authors find cosmic variance increases clustering errors by ~3x over Poisson estimates and widens minimum halo mass uncertainties by 1.5-3x for z~6 quasars and emission-line galaxies.
A new three-point inverse solution using the α-β model reconstructs meteoroid masses and bulk densities from limited fireball observations, achieving 88% convergence on the EN catalog and producing a continuous density range of 300-4000 kg m^{-3} instead of discrete PE categories.
A causal machine-learning model using variability features from Fermi-LAT light curves predicts blazar flare activity within 90 days with 86% recall on held-out data for one FSRQ.
SPHEREx data confirm 77 new luminous heavily reddened quasars at 1.5<z<3.9 that are hot-dust poor relative to unobscured quasars, supporting a blow-out feedback phase.
Direct [OIII]4364-based metallicities show that galaxies with stellar masses 10^6.7-9 solar masses at z~6-8 are 0.3-0.5 dex more metal-poor than local galaxies of the same mass, with slope 0.25 and 0.2 dex scatter.
Black hole supernovae occur across a wide progenitor mass range from 19.5 to 60 solar masses, yielding final black hole masses of 3 to 26 solar masses that trend with but are not fully set by CO core mass.
A new fitting methodology applied to UV absorption data recovers radial trends in galactic wind velocities and mass-loading factors by constraining initial hot and cool phase parameters in a multiphase model.
3D kinetic simulations of pre-merger binary neutron star magnetospheres predict nonthermal gamma-ray signals at ~16 MeV and fast radio burst-like radio transients from reconnecting current sheets.
Advection-only galactic wind models fail to reproduce observed vertical radio profiles without unrealistic velocities, synchrotron spectra are biased toward young electrons in dense regions, and bremsstrahlung/Coulomb losses cannot be neglected even when subdominant.
Empirical isochrones in photometric diagrams enable identification of unresolved binaries in eight nearby open clusters, yielding binary fractions of 0.16-0.44 and mass ratio modes around 0.4-0.8.
A JWST census detects neutral ISM absorption in 76 of 309 galaxies at 0.6<z<4 and outflows in 26, indicating AGN-driven neutral outflows dominate in quiescent systems at cosmic noon.
The mHz QPO in 1ES 1927+654 has persisted and stabilized at ~2.5 mHz with stable soft lags, no strong harmonic, and repeatable large-amplitude flux patterns, also seen in NuSTAR.
New JWST and Keck data on off-nuclear TDE 2025abcr show shifting emission-line velocities from a changing reprocessing layer and an IR power-law slope of -2.13 that is consistent with either reprocessing gas or a young stellar cluster of mass ~10^7.6 solar masses.
Inverting Fisher biases enables quick checks on whether specific systematics explain cosmological tensions.
Spectroscopic observations of six low-mass, metal-poor SLSN host galaxies reveal slow stellar-wind-driven outflows with velocities 37-104 km/s and mass-loading factors below 1 in the earliest phases of star formation.
A newly detected stellar substructure beyond 30 kpc in the Milky Way halo matches simulated LMC tidal debris only under the second-passage orbital model.
XRISM spectroscopy of AM Herculis reveals bulk velocity and temperature gradients in the radiative cooling accretion column, with derived shock temperature of 24 keV, velocity of 1116 km/s, and density of 5-6 x 10^15 cm^-3.
Filament dark matter density profiles become nearly universal when scaled by terminal halo virial radii, with the inner cusp produced by embedded halos and the smooth component showing a flat core that evolves from smooth to clumpy accretion.
RRATs number up to 400000 in the Galaxy with a birth rate of at most 1.4 per century, comparable in size to pulsars at high luminosities and consistent with supernova rates.
Domain adaptation with an ensemble of CNN and transformer models trained on DES detects 20,180 LSBGs and 434 UDGs in KiDS DR5, with structural parameters and environmental trends consistent with known samples.
tSZ cross-correlations with large-scale structure tracers prefer low S8 and strong baryonic feedback, yielding S8 = 0.72 and low group baryon fraction in FLAMINGO simulations.
Baryonic fraction in certain galaxies correlates with baryonic acceleration as approximately a_bar inverse, placing known dark-matter-deficient galaxies at the high-acceleration extreme and predicting low dark matter content for ultra-diffuse galaxies brighter than 25 mag arcsec^{-2}.
