Quasars, also known as QSo or Quasi-Stellar Objects, is an Powerful luminous active galactic nucleus (AGN). The AGN occurs when, a gaseous accretion disk surrounds a Supermassive Black Hole that is millions to billions fold the size of The Sun. The gaseous accretion disk plummets into The Supermassive Black Hole producing tons of energy called electromagnetic radiation. The Super Power produced by a Quasar is colossal and The Top Powerful Quasars produce a luminosity multi thousandfold that of a Galaxy.
Quasars were first discovered in The Late 1950's via The All-Sky Radio Surveys with the first two being 3C 48 & 3C 273. In 1960, Hundreds of Quasars were discovered that year alone. These discoveries were recorded in the Third Cambridge Catalogue. In 1963, The ID of 3C 48 as an olptical object was confirmed. IN The 1970's it was discovered that not all quasars were Super Powerful as initially researched in the earlier years.
Subtypes of Quasars
The taxonomic scheme of Quasars come in many varieties of different subtypes. Some of these are:
- Broad Absorption-line Quasars or (BAL) Quasars are those quasars that display a broad amount of absorption lines that are blue shifted to that of it's own rest frame. This is a result of the gas flowing out of the active nucleus in the direction of the observer.
- Optically Violent Variable or (OVV) Quasars are those that are radio-loud and have The Jet are pointed toward the observer.
- Radio-Loud Quasars are quasars with Powerful Jets that are intense sources of radio-wavelength emission.
- Radio-Quiet Quasars are quasars less powerful jets, with weaker radio emission than that of the radio-loud Quasars.
- Red Quasars are quasars with optical colors that are redder than normal and this is thought to be because of moderate amounts of dust within the quasar host galaxy.
- Type II Quasars are quasars where the accretion disk and broad emission lines are highly obscured by a dense amount of gas and dust
- Weak Emission Line Quasars are quasars that have a hard to make out emission lines of that of the ultraviolet/optical spectrum.
Name of Quasars
A few of the names of confirmed Quasars are 3C 48, 3C 273, Einstein Cross, Twin Quasar, Triple Quasar, Cloverfield, Teacup Galaxy, Webster LQG & QQQ J1519+0627
