Lprime {cosmoFns}

Line luminosity, L'

Description

Compute L' line luminosity

Usage

Lprime(intInt, z, f.rest = 115.27, omega.m = 0.27, omega.lambda = 0.73, H.0 = 71)

Arguments

intInt

Integrated intensity in Jy km/s

z

Redshift

f.rest

Line rest frequency in GHz

omega.m

Omega matter parameter

omega.lambda

Omega lambda parameter

H.0

Hubble constant in km/s/Mpc

Value

Rest-frame line luminosity in K km/s pc^-2.

Note

For flat universe, omega.k = 0. Useful for empirical mass estimates. L' is proportional to the brightness temperature of the transition.

wid <- 400   # 400 km/s wide
intInt <- 1.06*snu*wid  # Gaussian line
