people say that light emitted by quasar states that it is moving away from us? why? is it related to doppler effect? if so please explain.
A quasar, or quasi-stellar radio source, is an extremely luminous and energetic object found in the center of some galaxies. They are powered by supermassive black holes and emit large amounts of energy, including light, radio waves, and X-rays.
Quasars emit light through the process of accretion, where matter is pulled into the supermassive black hole at the center of the galaxy. As the matter spirals towards the black hole, it becomes extremely hot and emits light and other forms of energy.
The light emitted by a quasar can provide information about the physical properties of the quasar, such as its size, energy output, and the amount of matter being accreted by the black hole. It can also tell us about the environment surrounding the quasar and any gas or dust that may be present.
Quasars are among the most distant objects in the universe, with some being billions of light years away. This means that the light emitted by a quasar can allow us to see very far into the past, providing information about the early universe and the processes that were occurring at that time.
While the light emitted by quasars can provide valuable information for scientists, it is not currently used for practical applications. However, the technology and techniques used to study quasars have led to advancements in other fields, such as communications and imaging technologies.
