Sengi

DOI arXiv

(Published paper)

A small, fast, interactive viewer for Stellar Population Synthesis (SPS) spectra, using Non-negative Matrix Factorisation (NMF) and bilinear interpolation for reconstruction.

A live demo is available at christopherlovell.github.io/sengi

Sengi


Health Warning

Because of the nature of the NMF reconstruction the spectra generated by Sengi will not be exact. We show in the associated paper that the accuracy is sufficient for prototyping and education purposes, however for science purposes the original models should always be used.
