This paper proposes a deep neural network-based method that overcomes the limitations of conventional techniques by achieving both high computational efficiency and identification precision (97.26–99.91%) for weak stability boundary structures, thereby facilitating their application in ballistic capture analysis and low-energy transfer construction.
This paper presents the ASNOS dataset, a comprehensive collection of optical and near-infrared photometry for 41 Type Ia supernovae at low redshift, detailing the sample selection, data reduction, and light-curve fitting methods used to facilitate future cosmological analysis.
By applying the black-hole-envelope model to reanalyze the spectral energy distributions of approximately 400 Little Red Dots, this study demonstrates that interpreting these sources as accreting black holes shrouded in dense gas, rather than dust-reddened AGNs, resolves their puzzling spectral features and reconciles their cosmological demographics with the established evolution of black holes at .
Using high-precision radial velocities from HARPS-N combined with Gaia DR3 astrometry, the GAPS programme confirmed that the companion HD 128717 B (Gaia-6 B) is a long-period, high-eccentricity brown dwarf with a mass of approximately 20 Jupiter masses, correcting a previously inaccurate orbital solution derived solely from Gaia data.
This study utilizes an expanded catalog of 1976 interplanetary coronal mass ejection events observed from 0.07 to 5.4 au to demonstrate that their magnetic field evolution follows a single power law with an exponent of approximately -1.57, while revealing that a two-exponent multipole model is required to reconcile these interplanetary measurements with solar source field strengths.
This study presents the first detection of complex organic molecules and deuterated species in a shock-impacted clump at the interface of supernova remnant W44 and a molecular cloud, revealing chemical properties consistent with early-stage low-mass star formation that may preserve a chemical budget ultimately incorporated into planetary systems.
This paper forecasts the potential of [C II] line-intensity mapping surveys to constrain the mass of Warm Dark Matter particles, demonstrating that while current and near-future surveys can set lower limits on the particle mass, achieving competitive constraints comparable to other methods will require combining multiple redshifts and emission lines with advanced survey capabilities.
Using MUSE integral field spectroscopy, this study analyzes the stellar population properties of ultra-diffuse and low-surface brightness galaxies in the Hydra I cluster, revealing distinct formation pathways where most galaxies align with a puffed-up dwarf scenario while metal-richer inner galaxies suggest significant environmental influence.
Using high-resolution JWST observations of the strongly lensed galaxy HCM 6A at , this study reveals that feedback-driven multiphase interstellar medium structures and dust-cleared central clumps in young star-forming regions enable efficient Lyman- escape despite moderate dust content during the epoch of reionization.
Using the TARDIS radiative-transfer code combined with neural network emulation and MCMC inference, this study demonstrates that single high-velocity density enhancements cannot simultaneously reproduce the observed silicon and calcium high-velocity features in Type Ia supernovae, suggesting that current delayed- and double-detonation explosion models are incomplete.
By comparing star-forming galaxies with and without high-frequency radio detections, this study reveals that compact, GHz-detected systems exhibit AGN-like kinematic and morphological properties, suggesting they may harbor hidden, restarted, or relic AGN activity rather than being powered solely by star formation.
This study utilizes multi-survey light curves and infrared data to demonstrate that the variable mean magnitudes observed in approximately 0.9% of RR Lyrae stars in the Galactic bulge are genuine astrophysical phenomena, likely caused by variable dust extinction rather than photometric errors.
By combining cold plasma experiments and photochemical modeling on H2-rich gas mixtures, this study demonstrates that out-of-equilibrium chemistry in temperate exoplanet atmospheres drives the formation of diverse organic species, with production efficiency and chemical complexity heavily dependent on the C/O ratio and the balance between methane and oxidized carbon sources.
This paper proposes that magnetic fields spreading diffusively from stellar and galactic dynamos into their turbulent, poorly conducting exteriors form confined magnetospheres with distinct decay properties and expansion dynamics that differ from standard potential or force-free models, thereby ruling out such fields as the source of intergalactic void magnetization.
This paper explores the physics of nanohertz gravitational wave signals recently detected by pulsar timing arrays, examining their potential astrophysical origins from massive black-hole binaries and cosmological origins from early Universe phenomena to constrain high-energy physics and deepen our understanding of the cosmos.
This paper proposes and validates a double-aperture photometry strategy as a computationally efficient alternative to on-board centroid shifts for detecting false positives in the PLATO mission, demonstrating that secondary flux measurements achieve the highest detection efficiency (92%) for rejecting eclipsing binary contaminants among Sun-like stars.
By combining high-resolution LOFAR-VLBI, uGMRT, and VLA multi-frequency data, this study reveals the complex spectral, morphological, and polarized properties of filaments in the merging galaxy cluster Abell 2255, identifying steep-spectrum extensions up to 250 kpc and highlighting the Original TRG as the primary driver of these structures.
This study utilizes JWST and HST observations to reveal that a young, in-situ formed star cluster within a tidal bridge of an interacting galaxy pair at z=3 exhibits a high Lyman-continuum escape fraction of 57%, suggesting that such tidal features play a crucial role in facilitating ionizing radiation escape and shaping the diversity of Lyman-continuum emitters at Cosmic Noon.
By applying hydrodynamically-consistent PoWR-HD modeling and Gaia DR3 parallaxes to a sample of six Galactic WN4b stars, this study resolves parameter degeneracies inherent in traditional grid-based analyses to reveal a narrow temperature range, confirm the existence of low-luminosity Wolf-Rayet stars, and identify distinct mass-loss characteristics compared to WN2 stars.
This study presents the first self-consistent 3D MHD simulation demonstrating that decayless kink oscillations in solar coronal loops emerge spontaneously with linear polarization, suggesting a self-sustained driver rather than a stochastic source.
