Beschreibung
This book employs sophisticated statistical and computational techniques, including machine learning, to characterize the spectra of electromagnetic counterparts to gravitational wave sources. Specifically, the author studies the explosions associated with neutron star collisions called kilonovae, developing the SPARK tool to infer rapid neutron capture (r-process) abundance patterns and offer insight into the production of heavy elements in the Universe. The innovative methods implemented by the author in SPARK are insightful for characterizing spectra from the first neutron star merger, GW170817, and will be essential for understanding the properties of the broader population of kilonova explosions. SPARK is thus poised to become a high impact, open-source tool, making this thesis essential reading for the astrophysics research community.
Nominated as an outstanding PhD Thesis by McGill University, Canada Presents the SPARK tool and shows how it reveals new characterizations of the spectra of neutron star collisions Offers new insights into the origins of the heaviest elements
