GW190521 as a Merger of Proca Stars: A Potential New Vector Boson of 8.7 x 10 -13 eV

Advanced LIGO-Virgo have reported a short gravitational-wave signal (GW190521) interpreted as a quasicircular merger of black holes, one at least populating the pair-instability supernova gap, that formed a remnant black hole of ∼142  ⊙ at a luminosity distance of ∼5.3  Gpc. With barely visible pre-...
