Careers for Physicists
Becoming a Professor
Time: 3:30 pm - 4:30 pm
Place: 2124 Chamberlin
Speaker: Segev BenZvi and Naoko Kurahashi Neilson, UW-Madison
Abstract: How do you apply for faculty positions? How do you get interviews? What are faculty interviews like? If you ever wondered about how one gets interviews and faculty positions, come join us for this panel discussion on academic job application and interviewing. Postdocs currently undergoing the application and interview processes will discuss what their experiences have been like.

Distinguished Lecture Series
Cosmology on a Moving Mesh
Time: 4:00 pm - 5:00 pm
Place: 1310 Sterling Hall
Speaker: Lars Hernquist, Harvard University
Abstract: Understanding the formation and evolution of galaxies in a cosmological context using numerical simulations remains an elusive goal. In this talk, I describe a new approach to modeling the hydrodynamics of galaxy formation in which the equations of motion are solved on a moving mesh. The use of a moving mesh makes the scheme fully Lagrangian, unlike popular particle-based codes which are quasi-Lagrangian in nature, and mitigates against advection errors when a spatially fixed grid is used. I present results from an initial study comparing results for a moving mesh with those obtained using a smoothed particle hydrodynamics solver. This preliminary work suggests that the new approach offers promise for resolving the long-standing problems which have plagued this field for nearly two decades.<br>
