Let there be light: Illuminating kilonovae with POSSIS
Abstract: The detection of an electromagnetic counterpart to the gravitational-wave source GW 170817 marked year zero of the multi-messenger gravitational-wave era. This event was generated by the merger of two neutron stars and gave rise to an electromagnetic transient, dubbed a “kilonova”, which was intensively monitored with all the main ground-based and space-borne facilities. Kilonovae will be routinely discovered in the coming decade and our progress in multi-messenger astronomy will therefore be hampered by our ability to connect future observations to available models. In this talk, I will present the code POSSIS and show how radiative transfer simulations can provide such connection, predicting viewing-angle dependent synthetic observables - as light curves, spectra and polarization - that can be used to interpret data, place constraints on models and guide future follow-up campaigns of gravitational-wave triggers.
