SDSS J151451.78+311654.0 also known as CSO 1085, is a quasar located in the constellation of Corona Borealis. At the redshift of 2.13, the object is located 10.6 billion light-years from Earth.[1]
Characteristics[edit]
SDSS J151451.78+311654.0 is classified as a radio-quiet luminous quasar between the redshift range between 1.7 ≤ z ≤ 2.7.[2] It has a bolometric luminosity correction that is relative to 2500 Å BC2500 Å =2.75 ± 0.40 via from integrated light from 1 μm-2 keV through spectral energy distributions (SEDs) whom researchers used mid-infrared data from Spitzer and WISE, near-infrared data from the Two Micron All Sky Survey and UKIDSS, optical data from the Sloan Digital Sky Survey, and ultraviolet data from the Galaxy Evolution Explorer.[3] It is also known to be variable, which it is at rest-frame wavelengths from 1000 Å to 6000 Å[4] with one emission-line present at full width at half maximum larger than 500 km s-1.[5]
Black hole[edit]
The black hole in SDSS J151451.78+311654.0 is estimated to have a solar mass of logMBH between 7.1 and 9.9 M⊙ with a bolometric luminosity between 44.4 and 47.3 logLbol erg s-1 according to researchers calculating single-epoch virial black hole masses (MBH) for the sample using Hβ, Mg II, and C IV emission lines based from derived emission line parameters. By using the ratio of Lbol to the Eddington luminosity as a measure of the accretion rate for the quasar, the logarithm of the accretion rate is found between the ranges between -2.06 and 0.43.[6]
