Exploring Composition Mixing in Kilonova Ejecta with Ray-by-ray Simulations
Ruocheng Zhai, David Radice, Fabio Magistrelli +2
Binary neutron star merger (BNSM) ejecta are considered a primary repository of -process nucleosynthesis and a source of the observed heavy-element abundances. We implement comp…
Impact of in situ nuclear networks and atomic opacities on neutron star merger ejecta dynamics, nucleosynthesis, and kilonovae
Fabio Magistrelli, Sebastiano Bernuzzi, Albino Perego +2
Modeling binary neutron star merger (BNSM) ejecta evolution requires simulations involving hydrodynamics, nuclear reactions, and radiative processes. The impact of nuclear burning…
Impact of Neutrino Flavor Conversions on Neutron Star Merger Dynamics, Ejecta, Nucleosynthesis, and Multi-Messenger Signals
Yi Qiu, David Radice, Sherwood Richers +3
We present numerical relativity simulations of binary neutron star mergers incorporating neutrino flavor transformations triggered by fast flavor instability, quantum many-body eff…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Remnant properties of binary neutron star mergers undergoing prompt collapse
Arnab Dhani, Alessandro Camilletti, David Radice +4
We study the properties of remnants formed in prompt-collapse binary neutron star mergers. We consider non-spinning binaries over a range of total masses and mass ratios across a s…
Direct Measurement of the Accretion Disk Formed in Prompt Collapse Mergers with Future Gravitational-Wave Observatories
Arnab Dhani, Alessandro Camilletti, Alessio Ludovico De Santis +6
The production site of heavy r-process elements, such as Gold and Uranium, is uncertain. Neutron star mergers are the only astrophysical phenomenon in which we have witnessed their…
