Built-in BayeSN Models

Summarised here are the different models currently built-in to this BayeSN code. Alternatively, you can train your own models and use those within the code.

M20 model:

• Mandel et al., 2022 (MNRAS 510, 3, 3939-3966, https://ui.adsabs.harvard.edu/abs/2022MNRAS.510.3939M/abstract)

• Trained on 86 SNe Ia compiled in Avelino+19 (as described in Mandel+22)

• Training data includes BVRIYJH only

• Wavelength range 3000 - 18500 A

• Not suitable for u/U band, even if included in wavelength range

• Milky Way extinction based on SF11

T21 model:

• Thorp et al., 2021 (MNRAS 508, 3, 4310-4331, https://ui.adsabs.harvard.edu/abs/2021MNRAS.508.4310T/abstract)

• Trained on 157 SNe Ia from Foundation DR1 (Foley+18, Jones+19)

• Training data includes griz only

• Wavelength range 3500 - 9500 A

• Milky Way extinction based on SF11

W22 model:

• Ward et al., 2023 (ApJ 956, 2, 111, https://ui.adsabs.harvard.edu/abs/2023ApJ…956..111W/abstract)

• Trained on Foundation DR1 (Foley+18, Jones+19) and Avelino+19 compilation, combination of data sets for M20 and T21

• Training data includes BgVrizYJH

• Wavelength range 3000 - 18500 A

• Milky Way extinction based on SF11
