Abstract:
The propagation and evolution of cold galactic winds in galactic haloes is crucial to galaxy formation models. However, modeling of this process in hydrodynamic simulations of galaxy formation is over-simplified owing to a lack of numerical resolution and often neglects critical physical processes such as hydrodynamic instabilities and thermal conduction. In this thesis, I propose an analytic model, Physically Evolved Winds (PhEW), that calculates the evolution of individual clouds moving supersonically through a uniform ambient medium. The model reproduces predictions from very high resolution cloud-crushing simulations that include isotropic thermal conduction over a wide range of physical conditions. I also describe the implementation of this model into cosmological hydrodynamic simulations of galaxy formation as a sub-grid prescription to model galactic winds more robustly both physically and numerically.
It is with immense pleasure that we announce Dr. Alexandra Pope's promotion to Full Professor. Congratulations Prof. Pope!

Sinclaire's research focuses on studying the enigmatic population of dusty star-forming galaxies in the early Universe.
"The Goldwater Scholarship Program, one of the oldest and most prestigious national scholarships in the natural sciences, engineering,and mathematics in the United States, seeks to identify and support college sophomores and juniorswho show exceptional promise of becoming this Nation’s next generation of research leaders in these fields."
Kate is a Physics major with a concentration in Astronomy, who is working on a project to understand star formation in nearby galaxies.
Profs. Gopal Narayanan and Pete Schloerb are among the authors of a new publication by the Event Horizon Telescope collaboration on the supermassive black hole in the center of the galaxy M87. This new paper shows, for the first time, the signatures of the magnetic field surrounding the black hole. These observations help illuminate how black holes launch powerful, galactic-scale jets.
