You have just detected a fast radio burst. The burst had a flux of 2.3x10-20 W m- and lasted for 1.4 milli-seconds. You were able to determine that the burst came from a galaxy at redshift 0.00106. A) If the burst was fired out equally in all directions from the source, what was the total energy of the burst? (5 marks) B) Now imagine that the burst came from a jet fired out from the source, travelling at 99% the speed of light, in a direction straight towards the Earth. What would be the approximate total energy of the burst now
