Evidence for Dark Matter.

For decades astronomers and astrophysicists have been aware that not all of the matter in the universe is visible. However, just because we can't see this matter directly , the gravitational influence of this unseen "stuff" can still be observed indirectly. We now call this "stuff" dark matter. Furthermore, we now know that ark matter is different from ordinary matter and that there is more dark matter in the universe than ordinary matter. In this talk we will discuss have we have arrived at this astonishing conclusion and what we know about dark matter.

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.
