5 000 A Student Is Observing An Image Of A Distant Quasar A Galaxy With Active Black Hole In Its Center Via A Telesco 1 (117.01 KiB) Viewed 23 times

5.000 A student is observing an image of a distant quasar (=a galaxy with active black hole in its center) via a telescope coupled to a spectrometer. He found that the prominent green Balmer line of hydrogen (486.1 nm) is seen shifted well into near infrared region - as 2119 nm line. How much is the speed of the quasar versus the student then? v= m/s; v/c= Is the quasar moving away or is it approaching the student? How far is the quasar from Earth? light years = m. Assume Hubble constant to be 70 km/s per Mpc. The student also found that the very same quasar image also shows bright 162 nm line in its center. Assuming that he sees the same 486.1 nm green line, student hypotheses that a hydrogen plasma jet is shooting from the central black hole pole at a very high speed. Find the velocity of this jet v= m/s, v/c = and state if the plasma in the jet is receding from the student or approaching How much is the speed of the jet versus the quasar itself? m/s; v/c (Note here that it can't exceed the speed of light)
