Neglecting Dynamical Microlensing Can Bias Accretion Disk Size Measurements at the Population Level
Microlensing of strongly lensed quasars probes unresolved accretion disks, but many inference methods use static magnification maps with fixed relative microlens positions.Identifying Scientifically Interesting Galaxies with Vision-Language Models
Anomaly searches in large astronomical image datasets aim to identify rare objects for follow-up investigation.Combining Multiple Incomplete Astronomical Surveys to Estimate Galaxy Flux Distributions
In astrophysics, the distributions of fluxes or intensities of populations of sources provide insight into the structure and evolution of the universe.Machine Learning Applications in the Solar Interior and Atmosphere
The solar interior and atmosphere constitute a strongly coupled, multiscale dynamical system defined by continuous temporal evolution.Power spectrum of longitudinal-velocity residuals in the Galactic disk from Gaia DR3 red-giant-branch stars
Non-axisymmetric structures in the Galaxy produce coherent stellar motions in the Galactic disk.Automated, auditable dating of the Babylonian Astronomical Diaries with language models and astronomical tools
The Babylonian Astronomical Diaries record the sky over nearly six centuries.ePNGCAT: the first eROSITA all-sky data release
The eROSITA telescope array aboard the joint German--Russian Spektrum-Roentgen-Gamma (SRG) mission delivered the deepest soft all-sky X-ray survey to date, scanning the entire sky more than four…Forward model of the Gaia DR3 selection function
The completeness of an astronomical catalogue depends on its selection function, which is a combination of the observing strategy, instrumental characteristics, and intrinsic properties of the…ARENA: Active Region attENtion Aggregation for interpretable solar flare prediction
Predicting solar flares is a challenging space-weather forecasting problem with potentially significant impacts on Earth's upper atmosphere, including disruptions to radio communications.Physics Informed Neural Network for Multi-dimensional Turbulent Self-gravitating Flows
Molecular clouds exhibit complex, multi-scale dynamics driven by the interplay of turbulence, self-gravity, and gas pressure.The SIRMOS mission concept: a space-based near-IR spectroscopic survey of 100 million galaxies in the Euclid Wide Survey footprint
SIRMOS is a mission concept for a future NASA Astrophysics Explorer opportunity that aims to revolutionize our understanding of the universe by mapping the large-scale structure of galaxies in…Lomb-Scargle Recovery of Periodic Binary Signals across Black Hole Mass and Cadence
Searches for periodic supermassive black hole binaries in quasar light curves rely on recovery fractions, the share of injected signals detected, which forecasts use as detection efficiencies.A cosmic filament catalog for COSMOS-Web Data Release 1 across 0.5 < z < 3.5
Cosmic filaments represent the environments in which most galaxies form and evolve.The SDSS-V Local Volume Mapper (LVM): Technical Overview
The Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM) is an ultra-wide integral field spectroscopic survey of the Milky Way, the Magellanic Clouds, and a sample of galaxies in the local…B-fields In STar-forming Region Observations (BISTRO): Technical Foundations for Quantitative 450/850 $μ$m JCMT SCUBA-2/POL-2 Polarimetry
We present five technical validations of SCUBA-2/POL-2 polarimetry on the James Clerk Maxwell Telescope at 450 and 850 $μ$m, using 174 archival fields in 69 molecular cloud regions and subsets…B-fields In STar-forming Region Observations (BISTRO): Dual-Wavelength Constraints on Size-Dependent Grain Alignment in Star-Forming Regions
We compared 450 and 850 $μ$m POL-2 observations from the James Clerk Maxwell Telescope at $12.6''$ resolution.simesh: A Python Framework for Quantitative Analysis of Native AMR Data from MPI-AMRVAC
Adaptive mesh refinement (AMR) is widely used in large-scale astrophysical simulations, but the resulting multilevel data are challenging to analyze quantitatively.Probabilistic Machine Learning for Short-Term Atmospheric Seeing Forecasting
Accurate short-term forecasting of atmospheric seeing is of significant interest for astronomical observations and free-space optical communication systems, where rapid variations in optical…Astro2Method: Benchmarking LLMs on Machine Learning Method Selection in Astronomy
Machine learning (ML) is increasingly used in astronomy, but choosing a suitable method for a scientific problem often requires expertise in both astronomy and ML.A Radiation-Hardened, Fault-Aware Quantized Neural Network That Self-Heals
Deep learning (DL) models are increasingly being deployed into radiation-challenging environments in spacecraft, particle accelerators, and, soon, space-based data centers.
