Extinction by non-spherical particles with the Nanoparticle Transition Matrix Code: perspectives for interstellar medium and exoplanetary atmospheres
The Transition Matrix formalism (T-matrix) offers an optimal solution to the problem of radiation scattering and absorption by particles characterized by a high degree of chemical and structural…Particle Selection in Virtual Reality
Point-cloud representations of 3D data are used in many fields, from astronomical surveys of galaxies to medical imaging and laser scans of buildings.An Ultraviolet Instrument on the Habitable Worlds Observatory: Considerations and Capability Trades on the Multi-Object, Integral-field, and High-resolution modes of a potential UVI
The Habitable Worlds Observatory (HWO) is NASA's next-generation astrophysics platform, delivering transformative capability in the search for life and study of the origins of the universe.Stellar discs and intermediate-mass black holes in galactic nuclei II. Fragmenting the disc and forming the S-stars in a live nuclear star cluster
We present direct $N$-body simulations of a stellar disc around the supermassive black hole Sgr~A*, perturbed by an intermediate-mass black hole (IMBH) and embedded in a live nuclear star cluster.Gravitational Microlensing
Gravitational microlensing is a unique planet-detection method that does not rely on detecting light from the host star or planet.Constrained Diffusion for Data-Scarce Orbital Monte Carlo in Constellation Tasking
Constellation Monte Carlo results depend on the orbital population used to evaluate a tasking policy.ASTRAL: A Framework for Optimal Placement and Emulation of Stellar Evolution Models
Generating dense grids of detailed stellar evolution simulations is computationally prohibitive, as resolving progressively complex nucleosynthesis chains and dynamical timescales incurs a rapidly…Registering Gaia positions on VLBI images: constraining opacity-driven core shift in B 1038+528 / B 1038+529
Because of the complex and time-variable radio structure of active galactic nuclei (AGNs), absolute astrometric positions cannot generally be registered unambiguously with specific features in VLBI…IMFIT-MW: Multiwavelength photometric decomposition with IMFIT
Photometric decomposition is often used to study galaxy structure by modelling surface brightness distribution in its components.Central stellar depletion in the Draco dwarf from Subaru photometry
Dark matter subhaloes are a fundamental prediction of the standard cosmological model, but their low-mass population remains difficult to constrain observationally.Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) II. Approach to data reduction and products for line-rich broadband (sub)millimeter spectra
Studying the chemical composition of the warm gas surrounding embedded solar-type protostars is one of the areas for which the Atacama Large Millimeter/submillimeter Array (ALMA) is particularly…Reflex instabilities I: Boundaries makes grid-based disc simulations frame-dependent
If the mass distribution within an accretion disc is asymmetric, it will exert a gravitational pull on its central object.Reflex instabilities II: The reflex motion of the central object drives at least seven instabilities in accretion discs
This series of papers studies the stability of accretion discs to the reflex motion of the central object under the gravitational pull of the disc itself.Modeling the nanohertz gravitational wave background with the t-process: Improved frequentist analysis of gravitational-wave power
Pulsar timing array (PTA) collaborations have recently reported evidence for a gravitational wave background (GWB) signal in the nanohertz band, which most likely originates from the incoherent…A method for multimodal analysis of TAIGA experiment data using essential features
The aim of processing and analyzing experimental data from physical experiments is to obtain physically significant information about the phenomenon under study.Armillary: A Label-Free Coordinate System for Stellar Spectra
A stellar spectrum is determined by a few parameters, so a set of spectra lies on a low-dimensional manifold with those parameters as its coordinates.AI Agents as a Research Team: A Human-Supervised Case Study in Stellar Spectroscopy
We present a qualitative case study of a human-supervised team of specialized AI agents supporting an astronomy research project.A Framework for Automated Multi-Source Satellite Data Analytics and LLM-Based Report Generation
This paper presents the workflow for building an automated ArcGIS Pro tool using ArcPy to extract the Land Surface Temperature (LST) from Landsat 7, 8 and 9 datasets.Stellar parameters and abundances for 3.2 million DESI DR1 spectra using machine learning
We present a machine-learning pipeline for determining stellar parameters and chemical abundances from spectra observed by the Dark Energy Spectroscopic Instrument (DESI).Cross-Modal Solar Image Synthesis: Adapting the Surya Foundation Model from He I 10830 Å to EUV Translation and Coronal Hole Segmentation
The long observational record of He I 10830 Å offers a means to investigate solar morphology before modern extreme-ultraviolet (EUV) imaging.
