6. This question is related to the mergers of stellar corpses. The relevant animations have been uploaded on D2L. (a) Consider a binary system consisting of two black holes. The orbits of the black holes decay till they eventually merge into one large black hole. After the merger, the single black hole eventually settles down. The entire process described was responsible for LIGO's 2015 signal, shown below. Strain LIGO's 2015 signal Jhmm Time a i. What is strain representative of? (5 points) ii. Explain the entire signal shown. Your answer should explain why the signal is a wave and why part of the signal shows a larger wave than others. (10 points) (b) What are gamma (7) ray bursts and why are they useful? (5 points) (c) Consider now a binary system consisting of two neutron stars. Their orbits also decay till the two stellar corpses merge into one. List two ways in which we can observe a neutron star merger. (5 points) (Total: 25 points)
