Do any quasars presently exist in our universe? Or are all the quasars gone?

A quasar is an extremely luminous and distant active galactic nucleus, powered by a supermassive black hole at the center of a galaxy. They emit large amounts of energy across the electromagnetic spectrum, making them one of the brightest objects in the universe.
Quasars are formed when gas and dust are pulled into the accretion disk surrounding a supermassive black hole. The intense gravitational forces cause the material to heat up and emit large amounts of radiation, creating the bright appearance of a quasar.
Quasars are located at extremely large distances from Earth, with some being billions of light years away. This means we are seeing them as they appeared billions of years ago, due to the time it takes for their light to reach us.
Studying quasars can provide insights into the early universe and the evolution of galaxies. They can also help us better understand the behavior of supermassive black holes and the effects of their powerful gravitational forces.
No, quasars are not visible to the naked eye. They are extremely distant objects and require powerful telescopes to be observed. However, some quasars have been observed in the infrared and radio wavelengths, which are not visible to the human eye.
