The Department of Physics welcomes Katerina Chatziioannou, a research fellow at the Flatiron Institute.
Abstract: Neutron stars, the most dense astrophysical bodies we know of, are at the heart of many interesting astrophysical phenomena from their birth in supernova explosions to their deaths in collisions with other dense objects. Even though we have been witnessing the births of neutron stars in the night (or even day!) sky for thousands of years, the collision of two neutron stars was detected for the first time only two years ago through gravitational waves.
In this talk I will briefly discuss what gravitational waves are, what creates them, and why they have the potential to serve as a novel messenger about the Universe that is complementary to electromagnetic waves. I will focus on the signal detected during the merger of two neutron stars, GW170817, and describe what information it has offered about the properties of astrophysical neutron stars. I will discuss what we expect to discover in the next few years with a focus on understanding the properties of matter that is more dense than the nuclei everyday atoms are made of.
All talks begin promptly at 12:10 p.m. Lunch will be served from 11:50 to 12:10.
