Concept information
Preferred term
flux density
Definition(s)
- Flux density is the radiant power (energy per unit time) that falls on a detector per unit surface area of the detector per unit bandwidth of the radiation. It thus measures both the spatial (surface) density and a spectral density of the flux received from an astronomical source. Flux density in radio astronomy is measured in janskys (Jy).
