SDSS J082535.19+512706.3 also known as QSO J0825+5127, is a quasar located in the constellation Lynx. Its redshift is 3.495596, which corresponds the object to be located 11.5 billion light-years from Earth.[1]

Characteristics[edit]

SDSS J082535.19+512706.3 was first discovered in 2003 by a team of astronomers, whom they presented 16,713 objects from the SDSS First Data Release which contain high luminosities than Mi=-22 (in a cosmology with H0=70 km s-1 Mpc-1, ΩM=0.3, and ΩΛ=0.7). These quasars also contain at least one emission line with FWHM larger than 1000 km s-1, with high redshifts ranging from 0.08 to 5.41, with a median value of 1.43.[2]

SDSS J082535.19+512706.3 is classified as a broad absorption line quasar,[1][3][4] specifically containing a high ionization trough, including an absorption redshift that is relative to the quasar's rest frame. Its redshifted trough extends upwards to velocities of v ≃ 12 000 km s−1, with its widths exceeding at least 3000 km s−1.[5]

Such of these broad absorption line quasars like SDSS J082535.19+512706.3 have a unique morphology, which they contain gas clouds absorbing flux at wavelengths of common quasar spectral features although their blueshifts have higher velocities more than 0.1c. These makes them interesting as they provide signatures of significant feedback, but also compromise cosmological studies, which the quasars are studied for their impact on accurate redshifts as well as measurements of the matter density distribution traceable by their Lyman-alpha forest.[6]

According to researchers, it has been proposed SDSS J082535.19+512706.3 might have gone a galaxy merger, triggering its active galactic nucleus that leads to large amounts of outflows pouring out from the quasar's center. This potentially affects the chemical make-up of interstellar medium thus reducing star formation in its host galaxy.[7][8]

Black hole[edit]

From the study conducted by researchers, it is found that the supermassive black hole in the center of SDSS J082535.19+512706.3 is surrounded by a luminous accretion disk, in which the quasar radiates hot amounts of interstellar gas. These signs indicates that SDSS J082535.19+512706.3 is in the process of rapid enlargement.[9]

Moreover, SDSS J082535.19+512706.3 is a hyperluminous quasar containing Mg II and Hβ emissions, which the said lines were used by scientists to study its black hole. Through the Eddington ratio, the black hole in SDSS J082535.19+512706.3 is found to have a solar mass of (1.12 + 0.20) x 1010. This makes the quasar to contain one of the most massive black holes.[9]
