target.sncc#

This module provides Core-Collapse (CC) Supernovae classes. See the corresponding documentation page in “List of transient classes” for more detail on those Transient class.

class skysurvey.target.sncc.VincenziModels[source]#

Bases: object

Default parametrization for the TimeSeriesSources based on Vincenzi et al. 2019. (Reference: https://ui.adsabs.harvard.edu/abs/2019MNRAS.489.5802V)

These are stored in sncosmo.

Parameters:

  • object (class) – The parent class of the VincenziModels class.

  • _KIND (str or None) – The specific supernova type (e.g., ‘II’, ‘IIP’, ‘Ib’). Used to identify the corresponding v19-*-corr template in sncosmo.

  • _TEMPLATES (str) – The template selection mode. For Vincenzi models, this is set to “complex” to handle the variety of templates associated with each supernova sub-type.

  • _RATE (float) – The volumetric rate of the transient. Defaults to np.nan. Users should provide a rate (typically in units of \(Gpc^{-3} yr^{-1}\)).

property template#

Returns:

The sncosmo source names matching the Vincenzi 2019 templates.

Return type:

list of str

property template#

List of sncosmo source names using the SNANA naming convention.

Returns:

The sncosmo source names matching the SNANA templates.

Return type:

list of str
