In essence the galaxy is eclipsing the quasar, but paradoxically its gravitational lens effect brightens the light received from the latter. |
The galaxy's hallmark is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy. |
You just don't get giant rotating disks from the accretion of small galaxy fragments. |
Astronomers discovered through CGRO data that the center of our galaxy glows in gamma rays created by the annihilation of matter and antimatter. |
At those rates, each galaxy could easily have formed the quasar and its black hole power source in just a few hundred million years. |
When she observed the galaxy later using the radio telescope, she found that it is embedded in a huge disk of atomic hydrogen gas. |
