25 New Quasars at Redshift 4.6 to 6.9: Peering Deep into Early Universe, Astronomers have identified 25 new quasars in the distant universe with redshifts between 4.6 and 6.9 (meaning their light began traveling towards us when the universe was very young). Six of those are at z is greater than equal to 6.5. These quasars are powered by supermassive black holes, and getting good spectra lets scientists estimate their masses and how fast they are accreting material. This pushes back our picture o

SOLVED: The spectrum of a quasar with a redshift of 0.20 contains twosets of absorption lines, redshifted by 0.17 and 0.185,respectively. If H0 = 70 km/s/Mpc, estimate the distance betweenthe intervening galaxies responsible for the two sets of lines inMpc.

It is concluded from measurements of the red shift of the emitted light that quasar Q1 is moving away from us at a speed of 0.788 c. Quasar Q2, which lies in the same direction in space but is closer to us, is moving away from us at speed 0.413 c. What velocity for Q2 would be measured by an observer on Q1 ? | Numerade
