AstroM3: A Self-supervised Multimodal Model for Astronomy

The Astronomical Journal
While machine-learned models are now routinely employed to facilitate astronomical inquiry, model inputs tend to be limited to a primary data source (namely images or time series) and, in the more advanced approaches, some metadata.

Squeezing Full-shape Dynamical Dark Energy Constraints with Galaxy Alignments

The Astrophysical Journal Letters
Recent 2 σ –4 σ deviations from the cosmological constant ${\rm{\Lambda }}$ suggest that dark energy (DE) may be dynamical, based on baryon acoustic oscillations and full-shape galaxy clustering (FS GC) analyses.

The next decade of astroinformatics and astrostatistics

, 2019
Over the past century, major advances in astronomy and astrophysics have been largely driven by improvements in instrumentation and data collection. With the amassing of high quality data from new telescopes, and especially with the advent of deep and large astronomical surveys, it is becoming clear that future advances will also rely heavily on how ...

Extreme-value Distribution Analysis of the Second CHIME/FRB Catalog: Assessing the Rarity of the One-off FRB 20250316A

The Astrophysical Journal
We present a statistical analysis of the extremely bright, apparently nonrepeating fast radio burst FRB 20250316A, detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME), to assess its rarity. Using a model-agnostic framework based on the

Distributions of Wide Binary Stars in Theory and in Gaia Data. II. Reconstruction of Sample Probability Density of True Orbit Sizes

The Astronomical Journal
Wide binary stars are important for testing alternative models of gravitation in the weak-field regime and understanding the statistical outcomes of dynamical interactions in the general Galactic field. The Gaia mission’s collection of weakly bound pairs
