FDF 4683 (abbreviation of FORS Deep Field 4683), also known as QSO B0103-260, Q0103-260 or simplify as QSO 0103–260, is a quasar located in the constellation of Sculptor. With the redshift of 3.36, the object is located 11.4 billion light-years from Earth.[1] The quasar is known to contain a high abundance of chemical elements, vital for studying the evolution of galaxies from early universe[2] with emission-line fluxes of NV 1240, CIV1549, and HeII1640 and a cosmological model applied with Omega _M =~ 0.3, Omega _Lambda =~ 0.7, and H_o =~ 65 km s−1 Mpc−1 that indicates the first violent star formation epoch starting at a redshift of z_f =~ 6 to 10.[3]

Observational history
edit
First seen as a bright white source by the FORS deep field program[4][5] and via Very Large Telescope at European Southern Observatory in 1998,[6] FDF 4683 was rediscovered in 2004 when astronomers decided to study it for cosmic evolution whom they observed the characteristic spectral properties, the evolution of the quasar's luminosity function and its chemical enrichment of the universe.[7][2]
