A Dirichlet process mixture model for marked Poisson point processes with squared-link intensities and Laplace variational inference jointly infers clusters, cluster count, and continuous mark-specific intensity surfaces.
Rotational averages of the angular correlation function isolate non-statistical isotropy components in the CMB sky as a real-space complement to BipoSH coefficients.
Two z~6.6 galaxies host overmassive black holes and show remnant ionized bubbles from recent quasar episodes, with BH-to-stellar mass ratios 400-800 times above the local relation.
Extended misalignment for axion-like particles with constant-ω_ϕ pre-oscillation and dark radiation coupling yields data-driven constraints favoring negative ω_ϕ and f_ϕ in [80, 1.5×10^10] TeV but does not ease cosmological tensions.
Euclid Ecliptic Survey data yields 889 high-quality asteroid spin periods (93% new) plus 16 super-fast rotator candidates, validated against known values.
Machine learning clustering of meteor observations produces a new hardness classification H_class that refines traditional Kb models using more parameters and reveals compositional structure in meteoroid populations.
LHAASO gamma-ray data from G150.3+4.5 and γ-Cygni show high-energy components produced by PeV cosmic rays from supernova remnants colliding with molecular clouds.
No CMB-consistent CPL dark energy model can simultaneously fit both the BAOtr and DESI datasets; the 3.7-sigma disagreement at z=0.51 sets an irreducible floor.
SPT-3G delivers the most precise CMB EE and TE spectra at high multipoles to date, giving LCDM parameters with H0 = 66.66 ± 0.60 km/s/Mpc from ground-based data alone and reaching Planck-level constraints when combined with ACT.
3D rMHD simulations show coronal nanojets originate in cool dense plasma during reconnection, explaining their collimation and visibility across wavelengths.
eROSITA data from solar minimum enables isolation and removal of solar wind charge exchange foreground emission, yielding a less contaminated diffuse soft X-ray sky and demonstrating X-ray mapping of interstellar matter flow.
TOI-201 has three planets whose co-transiting configuration will end in 200 years due to Kozai-Lidov oscillations driven by mutual inclinations.
Euclid identifies 16 massive compact galaxies with V-shaped SEDs at z>4, half as old as the universe at their redshift, mostly distinct from known AGN.
Modeling of Sgr A* shows Faraday conversion dominates circular polarization in radial, parabolic, quadrupole and combined magnetic fields while intrinsic emission dominates in dipole and vertical fields, allowing exclusion of reversed-field models at high inclinations using ALMA observations.
Intermediate-mass mergers explain the disputed origin and B[e] properties of several FS CMa stars.
Meteor clusters form near Earth mainly via thermal stress fragmentation, with their volume increasing with age, implying that distant older clusters remain undetected by local instruments.
Long-term spectroscopy of GJ 436 shows activity modulated by the planet's orbit, yielding a 6-110 G estimate for the warm Neptune's magnetic field via a new geometrical model.
SN peculiar velocities plus Planck CMB data give joint constraints on σ8, γ, and Ωk, with hints of positive curvature (Ωk ≈ -0.01) at 2-3σ and γ values consistent with GR.
Dust-cleaned CIB and CMB lensing cross-correlations yield f_NL^local = 43 ± 23, tightening constraints on local primordial non-Gaussianity.
Updating galaxy morphology inputs in Euclid shear calibration simulations from real data fits shifts the multiplicative bias by a percent level, five times larger than the allowed error budget.
The dispersion model yields unbiased fσ8 inferences from cluster 2PCF multipoles down to 10 h^{-1} Mpc in Euclid DR1-like settings with photometric redshift errors.
Improved quantitative detection of SASI in supernovae is reported using cWB XP on real LIGO O3/O4 data, with high identification probabilities at 1-10 kpc distances via ROC curves.
Coarse-grained spatial ordering can increase during structure formation even as full phase-space entropy grows through nonlocal transport, Jacobian-governed density amplification, and activation of lower free-energy branches in a Landau-Ginzburg description.
