Observational Overview
... In 1963, objects that looked like stars – called Quasars – were discovered to be the most distant objects in the Universe and thus incredibly luminous. The first object discovered 3C 273 was at a distance of 900 Mpc (= 3 billion l yr). The only possible explanation for the huge luminosities of such ...

These orbit black holes with masses of ~106-9 M, and radiate up to 1014 L, outshining all of the stars in the host galaxy. If we assume the black hole is not rotating, we can describe its spacetime with the Schwarzschild m ...

The disk includes new stars, planets, dust, and gas that all rotate around the center which is called the Galactic Center. The bulge consist of millions of o ...
