dc.description.abstract |
The detection rate of electromagnetic (EM) and gravitational wave (GW)
transients is growing exponentially. As the accuracy of the transient rates
will significantly improve over the coming decades, so will our understanding
of their evolution through cosmic history. To this end, we present predicted
rates for EM and GW transients over the age of the Universe using Binary
Population and Spectral Synthesis (BPASS) results combined with four cosmic
star formation histories (SFH). These include a widely used empirical SFH of
Madau & Dickinson and those from three cosmological simulations:
MilliMillennium, EAGLE and IllustrisTNG. We find that the choice of SFH
significantly changes our predictions: transients with short delay times are
most affected by the star formation rate, while long-delay time events tend to
depend on the metallicity evolution of star formation. Importantly we find that
the cosmological simulations have very different metallicity evolution that
cannot be reproduced by the widely used metallicity model of Langer & Norman,
which impacts the binary black hole merger and stripped-envelope supernovae
rates in the local Universe most acutely. We recommend against using simple
prescriptions for the metallicity evolution of the Universe when predicting the
rates of events that can have long delay times and that are sensitive to
metallicity evolution. |
