This proposal aims to create the first database of the simulated stellar content of the Universe,
from the earliest stars to the most exotic black hole binaries. This comprehensive stellar library will
be a world-wide scientific resource for astronomers, and an educational asset for the public. With
a state-of-the-art suite of computational tools, we can calculate the physical properties of individual
stars, evolve them in time, and track how they interact with each other as they age. With this library
of stellar populations that spans the known range of star formation histories and initial elemental
abundances, it is possible to tackle fundamental science questions that have been out of reach in
general relativity, astronomy, and cosmology. As a group we will use this database to characterize the
population of supernova progenitor stars that have been used to discover the mysterious dark energy
that accelerates the expansion of the Universe; we can calculate how (if at all) binary evolution
facilitates the formation of ultra-luminous X-ray sources, and we can model the number and physical
properties of neutron stars and black holes that strongly emit gravitational waves that are at the
heart of research into gamma-ray bursts – the most energetic explosions known-to-date. The data
that we create can be mined not only to match current observations, but to predict how the sky
will appear to future astronomical observatories as new windows to the Universe open. Altogether,
this proposal will allow us to consolidate a strong and highly visible research group; an independent
computational center that trains a new cohort of highly educated students, and communicates with
the public via innovative science venues, and offer a fresh look at the Universe.
