PDS 456 is a relatively nearby radio-quiet quasar located in the constellation of Serpens.[1] This is a luminous active galactic nucleus (AGN) with a redshift of (z) 0.184, first discovered by astronomers conducting the Pico dos Dias survey in 1997.[2][3][4] The object is known to have prototypical ionized ultra-fast X-ray outflows[5] and a bolometric luminosity value of 1047 erg s-1.[6][7][8]
