TESS photometry yields coherent periods for 1,362 CVs, including roughly 465–565 first determinations, and confirms the 2–3 h period gap with a median period near 3.68 h.
Experimental serial coupling of 1DDLC coronagraph and PFN achieves 3.5e-5 contrast at 6% wavelength offset, 20x better than coronagraph alone.
Optimal redshift weighting on eBOSS QSO full-shape data reduces uncertainties on H0 by 43.3%, σ8 by 19.7%, w0 by 20.5% and produces a bounded posterior on wa in the CPL model.
Massive galaxies at z>3.5 assembled stars earlier than theoretical models predict and exhibit gray dust attenuation, especially at the highest masses.
Corrected empirical limits show the most massive galaxies never exceed the theoretical baryonic maximum of 0.16 times halo virial mass, keeping observations consistent with LambdaCDM at all redshifts.
A multi-stage pipeline on Gaia DR3 data yields a census of 1,256 Stellar Snake candidates with 802,489 member stars, validated against external catalogs.
Oblique filament collisions lead to gravitational collapse of the compressed cloud when post-collision |gravitational energy| exceeds kinetic plus thermal plus magnetic energies, with lower angles and lower velocities favoring hub-filament formation.
High-resolution magnetic field maps of M17 SW reveal gravity-dominated energy budget with magnetic fields regulating collapse and accretion channels in a near-equipartition state.
A conditional variational autoencoder is trained on public kilonova light curves to enable rapid parameter inference for binary neutron star merger models in under three hours total.
Nearly every microjansky radio source in the NEP field has a bright JWST 4.4 μm host galaxy, and most hosts are star-forming, with a large minority showing active-galactic-nucleus signatures.
Observational study of 100 LMC GMCs finds median 13CO(2-1)/12CO(2-1) line ratio of 0.078, nearly linear with luminosity, and higher in clouds hosting IR-bright young stellar objects.
No kilonova detected from sub-solar GW candidate S251112cm, but coincident IIb supernova SN 2025adtq yields suggestive evidence for the superkilonova channel, though inconclusive after accounting for chance coincidence.
Simulations of the Aquila Rift show uneven clumps accreting gas and merging along filaments to form a fractal cluster whose velocity anisotropies, rotation, and expansion record the assembly history even after gas removal.
FRB 20240114A shows two epochs with distinct energy distribution indices and waiting time statistics, suggesting different burst types before and after March 21 2024.
SPHEREx spectra of 37 field brown dwarfs show atmospheric models struggle with J/H/K peaks and 4um window especially at L/T transition, with data preferring weak-mixing Elf Owl models.
VLBI imaging detects a compact radio source with Tb > 10^7 K and flat spectrum in the northern core of UGC 2369S, confirming a buried low-luminosity AGN.
Multi-telescope spectral modeling of HESS J1825-137 using Naima and MCMC shows leptonic dominance for existing GeV-TeV data but lepto-hadronic preference when adding simulated CTAO or LHAASO UHE points.
Reports results from two searches for new radio lenses in existing surveys and discusses the completeness of the population usable for constraining dark matter properties via astrometric perturbations.
3D MHD modeling of candle-flame solar flares reveals Y-points do not coincide with apparent cusp tips and observed downflow speeds underestimate reconnection Alfvén speeds by 2-10x.
Late-time radio rebrightening in SN 2012ap is consistent with either progenitor mass-loss variation producing a density enhancement or an off-axis energetic jet viewed at large angle, potentially reclassifying it as GRB-like rather than weakly engine-driven.
A single galaxy cluster lenses two quasars (one Type I at z=1.524, one dust-obscured Type II at z=1.939) into four images each, yielding a projected mass of ~3.3e14 solar masses within 500 kpc and time delays of hundreds to over 1000 days.
The primary beam of the Tianlai array is shown to be factorizable into independent E-W and N-S components, with E-W profiles measured from the Sun and N-S obtained via sky model fitting.
