TypeIcSNe#

class uvex_transients.transients.supernovae.TypeIcSNe(cosmology: Cosmology | None = None)[source]#

Type Ic core-collapse SNe: TypeIcSED.

Radioactive-decay Arnett diffusion x floored-photosphere blackbody, its priors fit to the 8-event SN Ic subsample of the Lyman et al. 2016 stripped-envelope SNe explosion-parameter catalogue, following TypeIaSNe/TypeIcBLSNe’s first-principles Arnett-model convention.

Methods

`compute_all_sky_yield`(duration)	Compute the expected intrinsic event count over the full sky.
`compute_all_sky_yield_ci`(duration)	Compute rate-only bounds on the expected all-sky intrinsic event count.
`event_rate`(z)	Compute the comoving event rate density at redshift(s) z, \(R(z;A)=A f(z)\).
`rate_shape`(z)	Return the shared core-collapse SNe redshift shape (Madau & Dickinson 2014) at redshift(s) z.
`registry`()	dict[str, type[TransientBase]]: A copy of every concrete subclass imported so far, keyed by class name.
`sample_event_count`(solid_angle[, duration, ...])	Sample the number of events in a given solid angle and duration.
`sample_event_redshift`(n_samples, *[, rng])	Draw n_samples redshifts from the rate-weighted redshift distribution.
`sample_events_on_healpix_grid`(nside, *, t_start)	Draw a Monte Carlo realization of events on a HEALPix grid, over a time window.

Attributes

`DEFAULT_Z_GRID_SIZE`
`DEFAULT_Z_LIM`
`RATE_CI`	Multiplicative (lower, upper) 90% confidence factors on rate.
`RATE_FRACTION`	This subtype's fraction of the total core-collapse SNe rate.
`all_sky_rate`	Expected all-sky event rate per observer year.
`all_sky_rate_ci`	Rate-only bounds on `all_sky_rate`.
`cosmology`	The cosmology used for luminosity-distance/volume calculations.
`duration_limit`	Upper bound on this transient's total duration.
`effective_volume`	\(\mathcal V\), the all-sky rate-weighted comoving volume.
`integrated_rate`	Expected event rate per observer time and solid angle.
`integrated_rate_ci`	Rate-only bounds on `integrated_rate`.
`luminosity_distance_grid`	\(D_L(z)\) at each point of redshift_grid.
