Standard supernovas and the future of the Universe.
In the early 20th century when astronomers realized that the Universe was expanding. Since that time one of the most profound questions we have puzzled over is "What is the future of the Universe?". Our ideas about this have changed rapidly over the past two decades as we have developed a method of using supernovae to measure the distance to galaxys. This has lead us to the surprising result that the Universe is accelerating it's rate of expansion. This talk will explain these ideas and concepts that are behind our rapidly changing view of the cosmos.
Prof. Swesty has been associated with astronomy at Stony Brook for twenty one years, initially as a graduate student and then, after 5 years at the University of Illinois, returning as a faculty member. He has studied core collapse supernovae, neutron stars, the behavior of neutron stars in close binary systems, and the properties of neutron star material.
