Abstract: Quasars are extremely luminous active galactic nuclei (AGNs) which consist of supermassive blackholes (SMBHs), surrounded by a rapidly rotating accretion disk, located at the centre of massive galaxies. Spectral analysis stands as a primary avenue for investigating these objects. Given the presence of broad emission lines (BELs) and broad absorption lines (BALs) in quasar spectra, the interpretation of these spectra holds significant importance. Analysing spectra of quasars offers valuable insights about the behaviour of quasars themselves and the behaviour of their parent galaxies.
