Title: Nucleosynthesis and electromagnetic outcome from compact object mergers and their legacy.
Abstract:
In the last decade the gravitational waves and multi-messenger time-domain astronomy provides a fresh view of the dynamic Universe andprecursor a new era in astrophysics. Notably, shed light on the astrophysics of compact objects,origin of the heaviest elements, and allow for unique probes of fundamental physics. Those heavy elements produced via the rapid neutron capture process and remains a question of intense debate for many years.A fresh example event is the "kilonova" emission that accompanied GW170817 revealed binary neutron star merger. I will discuss recent results on the binary neutron stars simulation and how other explosive transient like the collapse of massive rotating stars "collapsars" which give rise to long GRBs and the formation of heavy elements in the universe. In particular,I will focuson two frontier research areas - neutron star mergers and collapsar (/massive- collapsar). Also, highlight how multi-messenger astronomy may answer how does the Universe create the heaviest elements?
