Luminous efficiency function - Wikipedia

Luminosity is an absolute measure of radiated electromagnetic power (light), the radiant power emitted by a light-emitting object over time. In astronomy, luminosity is the total amount of electromagnetic energy emitted per unit of time by a star, galaxy, or other astronomical objects. In SI units, luminosity is measured in joules per second, or watts. In astronomy, values for luminosity are often given in the terms of the luminosity of the Sun, L⊙. Luminosity can also be given in term… Webb11 okt. 2024 · The luminous intensity for monochromatic light of a particular wavelength λ is given by: I ν = 683 ⋅ y ¯ ( λ) ⋅ I e, where I ν is the luminous intensity in candelas (cd), I e is the radiant intensity in watts per steradian (W/sr), y ¯ ( … Webb11 apr. 2024 · We present the Hα luminosity function (LF) derived from a large sample of Lyman break galaxies at z {\\sim} 4.5 over the GOODS-South and North fields.
