An intense radio source is found to coincide with a starlike object whose spectrum contains a pattern of intense emission lines in the visible range that matches that of the Lyman UV hydrogen spectral lines but is very redshifted.What is this object?

Question

Quizplus · Accepted Answer

The presence of intense radio emissions and a redshifted spectrum matching Lyman UV hydrogen spectral lines suggest the object is a quasar, which is a type of active galactic nucleus with a supermassive black hole at its center, emitting large amounts of energy and radiation. Option A is ruled out as the object is not a supernova explosion, but rather a continuous source of radiation. Option B is less likely as a black hole alone would not emit such intense radiation, and option D is not relevant as pulsars do not match the given characteristics of the object.
