Improving the Physical Interpretability of Gaussian Processes in Stellar Activity Modeling: A Study Case on Photometric Variability Among Stellar Clusters

Leslie Moranta, Jonathan Gagné, Jacqueline K. Faherty +12

Gaussian Processes (GPs) are widely used to model stellar variability in photometric surveys, but a statistically successful fit does not guarantee that the inferred hyperparameter…

A SPHEREx Pipeline and Spectral Library for Ultracool Dwarfs

Jonathan Gagné, Jacqueline K. Faherty, Azul Ruiz Diaz +72

We present a Python spectrophotometry extraction tool tailored for fast-moving point sources detected in the SPHEREx mission, and use it to construct a set of 0.75-5.0 m low-res…

Iterative Poisson Solvers for Self-gravity with the GPU Code Astaroth

Ruben Krasnopolsky, Touko Puro, Wei-Wen Li +5

We present the development and benchmarking of Poisson solvers for graphics processing units (GPUs). Implemented in the Astaroth platform, the solvers feature high computational ef…

A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294

Shifra Mandel, Kaya Mori, Paul A. Draghis +37

For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…

Euclid: A complete Einstein ring in NGC 6505

C. M. O'Riordan, L. J. Oldham, A. Nersesian +195

We report the discovery of a complete Einstein ring around the elliptical galaxy NGC 6505, at . This is the first strong gravitational lens discovered in Euclid and the fi…

JWST 1.5 μm and 4.8 μm Photometry of Y Dwarfs

Loïc Albert, Sandy K. Leggett, Per Calissendorff +20

Brown dwarfs lack nuclear fusion and cool with time; the coldest known have an effective temperature below 500 K, and are known as Y dwarfs. We present a James Webb Space Telescope…
