lowluminosity
lowluminosity is a term used in astronomy to describe objects or phenomena that emit very little light. This can apply to a wide range of celestial bodies and events. For example, some stars, particularly brown dwarfs, are considered low-luminosity because they are not massive enough to sustain nuclear fusion and thus produce very little heat and light. Similarly, some galaxies, known as dwarf galaxies, have significantly fewer stars and emit less light than larger galaxies.
In the context of active galactic nuclei (AGN), low-luminosity AGN (LLAGN) are a class of supermassive black
The study of low-luminosity objects is important for understanding the full spectrum of cosmic phenomena and
