This book addresses the mechanism of enrichment of heavy elements in galaxies, a long standing problem in astronomy. It mainly focuses on explaining the origin of heavy elements by performing state-of-the-art, high-resolution hydrodynamic simulations of dwarf galaxies. In this book, the author successfully develops a model of galactic chemodynamical evolution by means of which the neutron star mergers can be used to explain the observed abundance pattern of the heavy elements synthesized by the rapid neutron capture process, such as europium, gold, and uranium in the Local Group dwarf galaxies. The book argues that heavy elements are significant indicators of the evolutionary history of the early galaxies, and presents theoretical findings that open new avenues to understanding the formation and evolution of galaxies based on the abundance of heavy elements in metal-poor stars.
Yutaka Hirai is a special postdoctoral researcher (SPDR) at the RIKEN Center for Computational Science. He has participated in studies of galactic chemical and dynamical evolution using high-resolution hydrodynamic simulations. His research has mainly focused on enrichment of heavy elements from neutron star mergers and supernovae in Local Group galaxies. He received his B.Sc. in Physics from Waseda University in 2013, M.Sc. in Astronomy in 2015, and Ph.D. in Astronomy in 2018 from the University of Tokyo. He was awarded a Research Fellow by Japan Society for the Promotion of Science (JSPS) from April 2015 to March 2018.
