Slide 1: QUASARS SUMMITED BY : THIVYAN.R.R 09ME62 “B” SECTION CIT Slide 2: INTRODUCTIOIN WHAT IS QUASAR? PROPERTIES OF QUASARS QUASAR EMISSION GENERATION RED SHIFT BINARY QUASARS Slide 3: QUASARS ARE VERY ENERGITIC DISTANT GALAXCIES EMITTING INTENSE AMOUNT OF ELECTROMAGNETIC RADIATIONS. Slide 4: Quasars give off enormous amounts of energy - they can be a trillion times brighter than the Sun! Quasars are believed to produce their energy from massive black holes in the center of the galaxies in which the quasars are located Slide 5: Quasars and radio galaxies are simply different aspects of the same active galactic nucleus phenomenon, all powered ultimately by the same engines – supermassive black holes. :  Quasar emission spectrum :  Redshift is defined as an increase in the wavelength of electromagnetic radiation received by a detector compared with the wavelength emitted by the source. This increase in wavelength corresponds to a drop in the frequency of the electromagnetic radiation. Slide 8: In astrophysics, the red shift is denoted by z Slide 9: Quasars can be readily compared to those of small active galaxies powered by the emissions from supermassive black holes. :  BINARY QUASAR SYSTEM :  DOUBLE HELIX IN THE BINARY QUASAR EMISSION Slide 12: THANK YOU
