Research Abstract

A quasar, a super massive black hole locates at the center, is surrounded by ionized gas. Though physical properties of the gas are clues to unveil origin and evolution of quasars, it was hard to directly probe the spatial structure due to the large distance. However, a method by using gravitational lens which is developed by us make it possible. After we have finished analysis of observational data and model calculations, we found that ionized gas at the large distance extends as the same spatial scale as the gas in nearby quasars.
