nifty-ls: Fast Lomb-Scargle periodogram
nifty-ls evaluates the Lomb-Scargle periodogram very quickly and accurately. The Lomb-Scargle periodogram, used for identifying periodicity in irregularly-spaced observations, is useful but computationally expensive. However, when it is phrased mathematically as a pair of non-uniform FFTs (NUFFTs), FINUFFT (ascl:2412.007), which is really fast, can be leveraged to improve performance. It also enables GPU (CUDA) support and is several orders of magnitude more accurate than Astropy's (ascl:1304.002) Lomb Scargle with default settings.
