Simulation-Based Pretraining and Domain Adaptation for Astronomical Time Series with Minimal Labeled Data
Rithwik Gupta, Daniel Muthukrishna, Jeroen Audenaert
Astronomical time-series analysis faces a critical limitation: the scarcity of labeled observational data. We present a pre-training approach that leverages simulations, significan…
Causal Foundation Models: Disentangling Physics from Instrument Properties
Jeroen Audenaert, Daniel Muthukrishna, Paul F. Gregory +2
Foundation models for structured time series data must contend with a fundamental challenge: observations often conflate the true underlying physical phenomena with systematic dist…
Transfer Learning for Transient Classification: From Simulations to Real Data and ZTF to LSST
Rithwik Gupta, Daniel Muthukrishna, Nabeel Rehemtulla +1
Machine learning has become essential for automated classification of astronomical transients, but current approaches face significant limitations: classifiers trained on simulatio…
A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star
Marc Hon, Saul Rappaport, Avi Shporer +21
We report the discovery of BD+054868Ab, a transiting exoplanet orbiting a bright () K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA's Tr…
