Type Ia supernovas and fusion of black holes: Do they complement each other in measuring the expansion of the universe?

Abstract

This work aims to show if it is possible to perform distance measurements, complementing type Ia supernovae with the fusion of black holes. It will be evaluated if it is possible to refine the measurement of the accelerated expansion of the universe, through the detection of gravitational waves generated by the fusion of black holes and comparing them with the intrinsic luminosity of type Ia supernovae.
