Yes, quasars are the most luminous objects in the universe.
Objects that do not emit or give out light or energy of their own are referred to as non-luminous objects.
Those objects would be too cold to emit significant amounts of visible light.
Radio Telescope observe light of a different wavelength then optical light. Radio waves have a longer wavelength then visible light. Some interstellar objects barley emit any light in the visible spectrum but emit a significant amount of radiation in the radio spectrum. Radio telescopes enable us to view objects which emit in the radio spectrum.
Luminous objects are those that emit their own light. Examples of such objects include the following; the sun, lightened candle, stars, torch bulb and Hydrogen atoms.A luminous object is an object that gives off light. Here are some examples; A light bulb, torch, match, sun, lit candle.
