SAGUI: SED-based Segmentation of Multi-band Galaxy Images -- Application to JADES in GOODS-South
Rafael S. de Souza, Andressa Wille, Shravya Shenoy +11
We present sagui, a modular framework for the analysis of multi-band imaging data in spatially resolved galaxies, with synergies to integral-field spectroscopy (IFS). Building on t…
Beyond prewhitening: detection of gravity modes and their period spacings in slowly pulsating B stars using the multitaper F-test
Aarya A. Patil, Conny Aerts, Nikki Y. N. Wang +2
Gravity modes in main-sequence stars have traditionally been studied using a prewhitening approach, which iteratively identifies modes in the Fourier domain and subsequently tunes…
Improving Harmonic Analysis using Multitapering: Precise frequency estimation of stellar oscillations using the harmonic F-test
Aarya A. Patil, Gwendolyn M. Eadie, Joshua S. Speagle +1
In Patil et. al 2024a, we developed a multitaper power spectrum estimation method, mtNUFFT, for analyzing time-series with quasi-regular spacing, and showed that it not only improv…
Decoding the age-chemical structure of the Milky Way disk: An application of Copulas and Elicitable Maps
Aarya A. Patil, Jo Bovy, Sebastian Jaimungal +2
In the Milky Way, the distribution of stars in the vs. and vs. age planes holds essential information about the history of sta…
