Code and symbolic scripts for double (two-frequency) Lomb–Scargle periodograms and omnigrams, based on Scargle & Wagner’s astronomical time-series analysis work.
This repository contains several Python scripts written as a pipeline for raw file sorting (.fits), image reduction (overscanning, trimming, zeroing, etc. w/ flats & biases), & synthetic aperture photometry for spotted stars. [A. Dombrosky under Dr. J. B. Milingo, Maria Mitchell Association]
End-to-End Python implementation of LPPLS (Log-Periodic Power Law Singularity) framework for detecting financial bubbles and critical transitions. Features Filimonov-Sornette calibration, Lagrange regularization, Lomb-Scargle spectral validation, and Monte Carlo significance testing. Complete computational replication of Hosseinzadeh (2025).
Bayesian Generalized Lomb-Scargle (BGLS) and Stacked BGLS periodograms for Julia. Implements Mortier et al. (2015) and Mortier & Collier Cameron (2017).
Core GCNS, Gaia DR3, and TESS periodic-variability analysis pipeline
Published large-scale irregular time series regression pipeline (arXiv:2311.04470) integrating Lomb–Scargle period detection, feature engineering, and validated statistical modeling.
Lomb Scargle L1 version, as described in Makarov et al. 2024 (arXiv:2405.12324)
Physics-aware ML analysis of 3I/ATLAS (photometry + spectroscopy).
Zero-AI pipeline for mining public ZTF light curves — and an honest field report on why solo variable-star discovery is walled in 2026. Working niche: O-C timing of known eclipsing binaries.
ZTF white-dwarf photometry through the panelcast hierarchical panel-forecasting pipeline — an astronomy port with zero source changes
