This paper reports the spectroscopic confirmation of 16 dual quasars and 36 projected quasars using DESI DR1 data, highlighting a high-confidence strong gravitational lensing system and several close pairs that offer unique opportunities to study galaxy mergers and the circumgalactic medium.
This study combines N-body simulations and secular perturbation theory to demonstrate that the TWA 7 system's debris disk morphology and potential co-orbital structures can be explained by a dynamically cold configuration featuring a known outer planet and a sub-Jovian inner companion on a nearly circular orbit between 13 and 23 au.
This study proposes and demonstrates through three-dimensional magnetohydrodynamic simulations that the interaction between a fast magnetohydrodynamic shock and a molecular cloud possessing an hourglass-shaped magnetic field and density inhomogeneity drives the formation of radially aligned filaments in hub-filament systems via oblique shocks and Richtmyer--Meshkov-like instabilities, thereby explaining their morphology, selective mass accretion, and low star formation efficiency.
This paper presents ATLAS100, a comprehensive volume-limited catalogue of 1,729 supernovae and optical transients within 100 Mpc observed by the ATLAS survey over 5.75 years, featuring cleaned photometry, spectroscopic classifications, and derived light curve properties to analyze sample demographics and completeness.
This paper introduces and validates "Nemesis," a flexible and scalable multi-scale, multi-physics algorithm built on AMUSE that accurately simulates complex astrophysical systems like star clusters with planetary binaries, matching the precision of direct N-body codes while maintaining computational efficiency through effective time synchronization and parallelization.
This paper presents the MOSS II catalog of mid-frequency radio sources in the core region of the Saraswati supercluster, derived from deep MeerKAT L-band observations, which reveals a characteristic flattening in source counts at the sub-mJy level and a distinct "bump" feature potentially attributed to an enhanced population of star-forming galaxies and AGNs within these massive galaxy cluster fields.
This paper demonstrates that accounting for undetected binary stars in ultra-faint dwarf galaxies reduces their estimated dynamical masses by a factor of 1.5 to 3, challenging current dark matter models and the classification of certain systems as galaxies, while showing that multi-epoch observations can effectively mitigate this contamination.
Multi-wavelength observations of the extended X-ray source near 1LHAASO J0343+5254u reveal radio and infrared signatures consistent with a massive, merging galaxy cluster rather than a pulsar wind nebula, suggesting the X-ray emission originates from the intracluster medium and is unrelated to the PeV gamma-ray source.
This paper discusses various internal criteria and influencing factors for assessing the quality of data unfolding results in particle physics and related fields, addressing the challenge of evaluating deconvolution accuracy when external benchmarks are unavailable.
This paper demonstrates that in a class of "ultra slow-turn" multi-field inflation models, an exponentially decreasing turn rate can stabilize tachyonic isocurvature perturbations, allowing the total entropy perturbation to correctly assess stability even when the effective mass squared is negative.
Using ALMA observations spanning 2019 to 2023, this study reveals that the March 2023 periastron passage of the T Tau Sa/Sb binary triggered increased millimeter flux and morphological changes in the circumstellar environment due to enhanced accretion and potential magnetic or gravitational interactions, while also identifying a Keplerian-moving crescent-shaped dust structure in the disk of the tertiary T Tau N component.
This paper presents spectro-temporal analysis of VLA radio observations of six cataclysmic variables, revealing diverse highly polarized coherent emission consistent with electron-cyclotron maser or plasma radiation mechanisms, alongside unpolarized variability potentially linked to magnetosphere-diamagnetic blob interactions.
This paper presents a fast, robust method using synthetic spectra to derive relative small-scale magnetic field variations from high-resolution spectroscopy, enabling the study of temporal evolution in low-mass stars while highlighting potential biases in temperature estimates caused by magnetic activity.
This paper advocates for a more rigorous test problem for viscous hydrodynamics codes by introducing a nonuniform-density Gaussian velocity shear scenario that exposes errors in the calculation of viscous stress tensors, fluxes, and source terms, while also providing a detailed exposition of the Navier-Stokes equations in various coordinate systems.
This 2025 review article for the Particle Data Book provides a comprehensive overview of cosmological inflation, covering its theoretical foundations, observational constraints, model comparisons, and future prospects.
This paper demonstrates that a network of third-generation gravitational-wave observatories, specifically the Cosmic Explorer and Einstein Telescope, will be able to constrain the neutron star radius to within approximately 75–200 meters (90% credibility) across a relevant mass range by analyzing the loudest events from an expected 300,000 binary neutron star mergers in a single year, representing a tenfold improvement over current constraints.
This paper proposes an agnostic method for detecting extraterrestrial life by using agent-based modeling to identify spatial correlations between planetary characteristics and their locations, thereby prioritizing targets for observation based on the statistical likelihood of panspermia and terraforming effects rather than relying on uncertain single-planet biosignatures.
This paper introduces the Curvature Mapping Method, a new technique that utilizes polarization observations to map magnetic forces, and applies it to the Orion A star-forming region to demonstrate that while magnetic fields support low-density gas, they are insufficient to prevent the collapse of dense regions.
This chapter reviews the physics of colliding black holes and neutron stars, emphasizing how neutrinos influence observable signals and the nucleosynthesis of heavy elements in the ejected matter.
This chapter explores how planetary nebulae, formed by mass ejection from dying low-to-intermediate mass stars, serve as invaluable laboratories for studying astrophysics, astrochemistry, and astromineralogy.
