A new histogram-free likelihood method applied to simulated JWST observations of brown dwarfs shows that globular cluster ages can be determined with formal errors under 0.2 Gyr.
TOI-2195 A b is an inflated hot Neptune that likely originated as a Jovian planet losing ~90% mass through Roche lobe overflow during EKL-driven high-eccentricity migration triggered by a wide binary companion.
Four parameters suffice to describe dust attenuation curve diversity in TNG simulations, yielding a new symbolic-regression model that recovers curves and fluxes better than existing parameterizations while linking parameters to SFR surface density, metallicity, and geometry.
First reported seismic detection of an internal magnetic field reaching approximately 4 kG in the radiative envelope of the gamma Doradus star KIC 2309579 using the variable delta Ka sensitive to Kelvin gravito-inertial modes.
Using occultation-derived sizes and Herschel thermal data, the study identifies three previously unknown likely binary TNOs and reports satellite size estimates while confirming no sizable satellites are needed for three others.
A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.
WD–IMBH tidal disruption disks are advection-dominated, radiate near-Eddington soft X-rays, can emit Galactic MeV neutrinos, and produce decihertz GW bursts.
Neural-network surrogate accelerated MCMC infers multipolar magnetic field parameters for PSR J0740+6620 from NICER data, finding broad multimodal posteriors and disfavoring a zero-offset model.
TOI-1533 is confirmed as a rare compact system hosting an inner sub-Neptune and an outer hot super-Neptune-mass giant with nearly equal masses and very different radii.
Rest-frame optical galaxy SEDs from a 16-parameter SPS model are captured by five disentangled VAE latents (mass, young stars, dust, soft/hard ionization); metallicity and age are not independent drivers.
ALMA CO(3-2) observations with MCMC retrievals show latitudinal temperature trends on Neptune, including a cold southern polar layer at 300-600 mbar, consistent with Voyager at 10-100 mbar but new at deeper levels.
Eccentricity posteriors of dynamically captured binaries can be mapped to capture parameters and compared against environment velocity distributions to constrain host and infer decay time.
GJ 1132 b is estimated to have received at least 50 times the cumulative XUV flux of modern Earth with over 95% probability across models, supporting its classification as an atmosphere-free world.
SHAMe-SF modeling of small-scale DESI ELG clustering delivers 6% precision on σ8 and Ωm h², matching full DR1 results with 1% volume.
Reassessment of 12 TTV claims finds only two systems with compelling unique solutions for the perturbing planet, six with multiple viable solutions, and two with weak evidence overall.
dynesty is an open-source Python package for dynamic nested sampling that improves efficiency in Bayesian posterior and evidence estimation compared to MCMC on certain problems.
BAGPIPES fitting of 9289 massive quiescent galaxies shows most SFHs rise gradually then quench in 1-2 Gyr, with faster quenching at z>1 and slower at z<1, interpreted as multiple AGN feedback and gas-supply mechanisms.
New high-resolution spectra yield abundances for 7 neutron-capture elements in open cluster stars, revealing flat Milky Way gradients for second-peak s- and r-process species and shallower slopes for first-peak s-process.
Galaxy size-mass relations exhibit double power-law breaks at different pivot masses for quiescent versus bulge-dominated samples, coinciding with AGN activity scales.
Compares MH, MALA, HMC, NUTS, and AIES on differentiable likelihood emulators for ΛCDM and sterile-neutrino models, finding MALA and MH competitive in wall time despite NUTS needing fewer samples.
Validates redshift-space power spectrum and bispectrum analysis on Abacus-PNG mocks to recover unbiased f_NL constraints for Euclid spectroscopic sample.
Highland lunar impact flashes decay more slowly and last longer than mare flashes, indicating that early cratering stages depend on lunar surface lithology.
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.
