About SNCosmo

Package Features

  • SN models: Synthesize supernova spectra and photometry from SN models.
  • Fitting and sampling: Functions for fitting and sampling SN model parameters given photometric light curve data.
  • I/O: Convenience functions for reading and writing peculiar data formats used in other packages.
  • Built-in supernova models such as SALT2, MLCS2k2, Hsiao, Nugent, PSNID, SNANA and Whalen models, as well as a variety of built-in bandpasses and magnitude systems.
  • Extensible: New models, bandpasses, and magnitude systems can be defined, using an object-oriented interface.

The name SNCosmo

A natural choice, “snpy”, was already in use by the “SNooPy” package, so I tried to be a little more descriptive. The package is really specific to supernova cosmology, as it doesn’t cover other types of supernova science (radiative transfer simulations for instance). Hence “sncosmo”.
