• The detection of GW170817 and its electromagnetic counterparts allows to constrain the equation of state of dense matter in new and complementary ways. Very stiff equations of state are ruled out by the upper limit on the average tidal deformability, $\tilde\Lambda \lesssim 800$, imposed by the detected gravitational wave signal. A lower limit, $\tilde\Lambda \gtrsim 400$, can also be extracted by considering the large amount of ejected matter which powers the kilonova AT2017gfo. By using… CONTINUE READING
