Scalable Gaussian Processes for Integrated and Overlapping Measurements Via Augmented State Space Models

Ryan A. Rubenzahl, Soichiro Hattori, Simo Särkkä +4

Astronomical measurements are often integrated over finite exposures, which can obscure latent variability on comparable timescales. Correctly accounting for exposure integration w…

nifty-ls: Fast and Accurate Lomb-Scargle Periodograms Using a Non-Uniform FFT

Lehman H. Garrison, Dan Foreman-Mackey, Yu-hsuan Shih +1

We present nifty-ls, a software package for fast and accurate evaluation of the Lomb-Scargle periodogram. nifty-ls leverages the fact that Lomb-Scargle can be computed using a non-…
