Spectral Decomposition Reveals Surface Processes on Europa
Gideon Yoffe, Sahar Shahaf
Competing processes shape Europa's surface: geological activity replenishes material through resurfacing, while bombardment by charged particles alters surface chemical composition…

A Linearized Approach to Radial-Velocity Extraction. II: Shot-Noise-Limited Precision via Spectral Factorization
Sahar Shahaf, Barak Zackay
We generalize the short-time Fourier transform (STFT) formalism for radial velocity extraction to cases where the underlying spectral components are unknown. The method factorizes…
