With a description as immense as the cosmic wonder itself, quasar tsunamis carry huge amounts of energy across their host galaxies at over 10 percent of the speed of light.
Recently, NASA’s Hubble Space Telescope provided observations to study 13 quasars and their outflows, but astronomers using the international Gemini Observatory in Maunakea, Hawaiʻi, have uncovered an even more powerful source, which now sits at the top of the “most energetic quasar tsunami†list.
Found at the heart of massive galaxies, quasars are created when supermassive black holes are fed with material from its host galaxy.
As the active black hole pulls in the surrounding matter, it heats up gas around it to such extreme temperatures that it can shine 1,000 times brighter than its host galaxy.
The intense radiation emitted from the hot gas, which creates the quasar, also drives torrential winds that sweep material away from the galaxy’s center.-----
As detailed in The Astrophysical Journal, the outflow from SDSS J135246.37+423923.5 quasar was found by astronomers to travel at nearly 13 percent of the speed of light, powered by a supermassive black hole 8.6 billion times as massive as the Sun.
