In 2009, the National Institute of Standards and Technology (NIST) issued a scientific paper stating that in addition to the typical white light brightness rating of display devices, there was a need for providing "an equivalent measurement that will better describe a projector's color performance when rendering full color imagery". [1]
The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.
Spectrum from quasar HE 0940-1050 after it has travelled through intergalactic medium This view, taken with infrared light, is a false-color image of a quasar-starburst tandem with the most luminous starburst ever seen in such a combination. Quasars also provide some clues as to the end of the Big Bang's reionization.
Twin Quasar: 1979 Lensed into 2 images The lens is a galaxy known as YGKOW G1: First quasar found with a jet with apparent superluminal motion 3C 279: 1971 [25] [26] [27] First quasar found with the classic double radio-lobe structure 3C 47: 1964 First quasar found to be an X-ray source 3C 273: 1967 [39] First "dustless" quasar found
3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2] The derived distance to this object is 749 megaparsecs (2.4 billion light-years).
The difference in brightness between two bands is referred to as an object's color index, or simply color. On color–color diagrams, the color defined by two wavelength bands is plotted on the horizontal axis , and the color defined by another brightness difference will be plotted on the vertical axis.
This establishes the current offsets in color display. Depending on the calibration software and type of monitor used, the software either creates a correction matrix (i.e. an ICC profile) for color values before being sent to the display or gives instructions for altering the display's brightness/contrast and RGB values through the OSD.
Quasar is an American brand of electronics, first used by Motorola in 1967 for a model line of transistorized color televisions. These TVs were marketed as containing all serviceable parts in a drawer beside the picture tube. It was then established as a subsidiary brand, with all Motorola-manufactured televisions being sold as Quasar by Motorola.
