So it's not really accurate to estimate quasar thermal temperature from the "Brightness temperature," because the latter only applies to objects closely fitting Planck's black body law. We aim to study several key physical properties of quasar absorption-line. Make about energy transfer within the disk etc. Temperature of warm gas at z 2, constraints on the Mg isotopic ratio. On what parameters you put in to the model and what assumptions you To the details of what the emission spectrum looks like depends a lot The Luminosity of the Milky Way is equivalent to 25 billion Lsun. The Luminosity of the Sun is described as 1Lsun. Luminosity is the amount of energy that a star or galaxy produces. In fact, this quasar (designated SMSS J114447.77- 430859.3) is also the most luminous of these events for around the past two-thirds of the universes 13.8 billion-year existence. Temperature either: the temperature is higher towards the center, but Quasar Luminosity / Temperature If we use 1LMW as the luminosity of the Milky Way Galaxy, a quasar could have the luminosity power of 10 to 100,000 LMW. 15.9 Existence status Confirmed Discovery date 1957 Discovered by Braulio Iriarte and Enrique Chavira Physical properties Characteristics Extremely luminous Hosts the largest known black hole Distance 18.2 billion ly Brightness 100 trillion Suns Absolute mag. And a single accretion disk doesn't have a single Masses, different matter infall rates and generally differentĮnvironments. (and also it depends on what angle you are viewing the AGN fromĪnd similarly, there isn't a single value you can quote for theĪccretion disk temperature. The percentage of radiation that is thermal versus non-thermal variesįrom quasar to quasar, and for a single quasar is going to beĭifferent at different wavelengths, so there isn't one simple answer A question/answer over at discusses the issue of quasar spectral output.
