Physics and Astronomy Colloquium: "Exploring beyond the Standard Model with Lattice QCD"

Amy Nicholson (University of North Carolina)

4:00pm - 5:00pm David Rittenhouse Laboratory, A8

While the Standard Model (SM) of particle physics has been enormously successful in describing the world around us, there still remain many important and unanswered questions requiring…

Physics and Astronomy Colloquium: "Interstellar Objects"

Greg Laughlin (Yale University)

4:00pm - 5:00pm David Rittenhouse Laboratory, A8

During the past two years, two objects -- 1I 2017 'Oumuamua and C/2019 Borisov -- have been observed to pass through the Solar System after arriving from interstellar space. 'Oumuamua presented a series…

Rittenhouse Lecture: “The Illustris TNG hydrodynamic simulation of the Universe”

Lars Hernquist (Harvard University)

4:00pm - 5:00pm David Rittenhouse Laboratory, A8

A predictive theory of galaxy formation remains elusive, even after more than 50 years of dedicated effort by many renowned astrophysicists. The problem of galaxy formation is made difficult by the large range in…

Physics and Astronomy Colloquium: "Top Down Approach to Quantum Fields"

Jonathan Heckman (University of Pennsylvania)

4:00pm - 5:00pm David Rittenhouse Laboratory, A8

Quantum Field Theory (QFT) is the common language of particle physicists, cosmologists, and condensed matter physicists. Even so, many fundamental aspects of QFT remain poorly understood…

Physics and Astronomy Colloquium: "Exploring physics beyond the standard model of particle physics with neutrinos"

Christopher Mauger (University of Pennsylvania)

4:00pm - 5:00pm David Rittenhouse Laboratory, A8

Neutrinos are the most abundant type of fermion that we know exists, yet we do not understand basic properties of these particles like their masses. Since neutrinos are unaffected by strong and…
