... For H o = 65 km/sec/ Mpc , matter density Omega M = 0.25 and cosmological constant lambda = 0.75, the luminosity distance of this source is 43 billion lightyears. ... 11 Dec 98 - The Sloan Digital Sky Survey has found several new quasars with redshifts greater than 4.9 in a tiny fraction of their planned survey area. ... The spectrum of the new quasar with redshift z = 5.0 , seen at right, has three obvious emission lines so the line identification is secure and thus the redshift is reliable. ...
