Physics & Astronomy Colloquium: Laboratory and Astronomical Observations of Dense Matter, March 14

The Physics & Astronomy Colloquium Series presents Chuck Horowitz of Indiana University on “Laboratory and Astronomical Observations of Dense Matter” on Friday, March 14, at 4:10 p.m. in Walter 245.

Abstract: Compress almost anything enough (to ten to the eleventh grams per cc or more) and electrons react with protons to make neutron rich dense matter. This material is at the heart of many fundamental questions in nuclear physics and astrophysics. What are the high-density phases of QCD? Where did chemical elements come from? What is the structure of many compact and energetic objects in the heavens, and what determines their electromagnetic, neutrino, and gravitational-wave radiations? We present four very short stories how neutron rich matter is being probed in the laboratory with precision electron scattering experiments, through X-ray observations of neutron star radii, with supernova neutrinos, and finally with gravitational wave observations of mountains on spinning neutron stars.
