The Quasar Enigma –Massively Dense Luminous Objects at the Dawn of the Universe


Quasars of Early Universe


Black holes are usually formed in the explosive deaths of massive stars. In dense environments like globular clusters and the cores of massive galaxies, several black holes can merge together, forming an even more massive black hole. In addition, black holes at the centers of galaxies can accrete infalling gas, gaining in mass and size. If this process continues for billions of years, the black hole can become a supermassive black hole, like the one located at the center of our Milky Way Galaxy, weighing in at four million times the mass of the sun. 


Is Dark Energy Evolving? –Ancient Quasars May Offer the Answer

The Teacup Quasar


Observational cosmologists are actively searching for a “new physics” that may solve the enduring enigma of our rapidly expanding Universe. Quasars are the ancient cores of galaxies where a supermassive black hole is actively pulling in matter from its surroundings at very intense rates may old the clue to solving the mystery.
