2020 Physics/Theoretical Colloquium Thursday, January 30th , 2020 3:45 – 4:45 p.m. Rosen Auditorium (TA-53, Bldg. 001) Refreshments at 3:15pm Speaker: Prof. Sanjay Reddy Dept of Physics, University of Washington “Neutron Stars come of Age” Abstract: About 50 years after their discovery, neutron stars are poised to take centre stage in this era of multi-messenger astrophysics. In the not-so-distant-future (10-20 years) next-generation gravitational wave observatories will likely detect gravitational waves from hundreds of mergers involving neutron stars every year. I will highlight advances in theory and mention some key observations that have already provided fundamental new insights about neutron star properties and their central role in nuclear astrophysics. I will discuss how neutron stars, and extreme phenomena involving them, can serve as laboratories to study phase transitions in dense matter, nucleosynthesis, and dark matter in the coming decades.
