HST/WFC3 UV imaging of SR 12 c measures accretion luminosity of 1.65 ± 0.19 × 10^{-5} L_⊙ and rate of 8 ± 2 × 10^{-12} M_⊙ yr^{-1}, placing it at the end stages of giant planet assembly with a full UV-to-sub-mm SED.
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.
JWST data on NGTS-10A b shows nightside CH4 depletion caused by day-to-night horizontal transport rather than vertical mixing or non-solar abundances.
AGILE archival data reveal gamma-ray flares from a source matching IGR J17354-3255, with orbital phase correlation supporting physical association and high-energy emission from SFXTs.
Dynamical models with varying bar growth times Tg show that librations start at 54% of maximum bar strength (Qb=0.170) via proportional shifts in VR profiles.
Spectroscopic measurements confirm a tight 6D phase-space clump of four RGB stars as part of the distant southern spur of the Sagittarius stream, likely stripped from Sagittarius's halo in the earliest interaction phases.
Galaxy size at fixed stellar mass encodes the link between long-term gas inflow histories, current inner gas reservoirs, and metallicity via differences in assembly timing.
V486 Car is a near-contact binary with component masses 2.1 and 0.4 solar masses, radii 3.2 and 1.48 solar radii, temperatures 10000 K and 6200 K, plus evidence for a ~0.3 solar mass companion at a few AU.
Hierarchical Bayesian inference allows accurate recovery of intrinsic astrophysical source populations even when follow-up selection is unknown and correlated with parameters of interest.
Mutual information analysis of TNG50 simulations shows gravitational potential and total energy retain merger mass and infall time information longest, while radial velocity loses it within ~5 Gyr, with washout depending on radius, merger age, and mass.
The skd-tree partitions space into multiple slices per node along one dimension, compresses splitters, and applies a constant number of SIMD instructions per node to reduce levels and computations for multi-dimensional queries.
A public catalogue provides geometric and photogeometric distances plus uncertainties for 1.47 billion Gaia EDR3 stars derived via probabilistic inference with a three-dimensional Galactic prior.
Mid-IR search of NEOWISE yields 10 TDEs above 3e43 erg/s with volumetric rate 1.2e-10 Mpc^-3 yr^-1, showing suppression at high luminosity explained by reduced TDE rate for larger black holes.
A tiered observational strategy is outlined to identify planetary-scale broadband radio technosignatures (BRaTs) from advanced civilizations up to 100 pc away using multi-parameter diagnostics to separate them from natural signals.
HE 1237-2252 exhibits a changing-look event driven by intrinsic accretion-rate variations, revealing a two-component broad-line region consisting of virialized gas at ~27 light-days and disk emission at larger radii.
FIRE-2 simulations show that stellar radial redistribution scatter saturates at ~2 kpc for stars older than ~3 Gyr, with net orbital changes depending on age and current radius, broadly matching Milky Way observations.
Tertiary in EM Boo is A-F type with Teff=7000K; system distance ~300 pc indicates Gaia DR3 underestimates true distance due to multiplicity.
A large sample of blue horizontal-branch stars reveals that the Milky Way halo anisotropy increases from the center, stays radially dominated after removing merger debris, and shows older stars on colder, less radial orbits in the inner regions.
Model-independent masses and radii plus effective temperatures are derived for the F9 V primary (M1=1.36 Msun, R1=1.72 Rsun, Teff=6197 K) and M-dwarf secondary (M2=0.56 Msun, R2=0.53 Rsun, Teff=3770 K) in CD-27 2812.
Nominal RUWE thresholds of 1.15 (DR4) and 1.11 (DR5) derived from Gaia Universe Model simulations increase detectable short-period binaries by 5-10% and long-period systems by 10-20%.
Recalibration of the Hα surface brightness-radius relation with Gaia DR3 parallaxes yields new distances for 1130 planetary nebulae and shows breaks in the Milky Way oxygen radial gradient near the solar radius.
Natal kicks from supernovae are proposed to disrupt Gaia progenitor binaries containing low-mass black holes more frequently than those leading to gravitational-wave mergers, accounting for the observed difference in the 2.5-5 solar mass gap.
Joint SKA PTA and astrometry analysis improves gravitational wave background detection sensitivity by 10-50%.
