Galaxy Evolution in a Computer Box, or “How to turn a PhD on Theoretical Galaxy Evolution into a Scientific Programming Career with NASA”
Jacob Vander Vliet, NASA/SOFIA
I graduated from NMSU in 2017 with a PhD entitled “Observing the Baryon Cycle in Hydrodynamic Cosmological Simulations”. I am happy to discuss the journey I took from primarily scientific interest in this problem to a primarily programming and computational interest in this problem. One of the major outcomes of my dissertation was to build pipeline software for analysis of the hydrodynamic simulations using the “quasar absorption line technique from which we study the circumgalactic medium in the simulations in order to learn about the so-called baryon cycle. Following graduation, I continued on as a “research assistant” at NMSU, and then landed a job with NASA at Stratospheric Observatory for Infrared Astronomy (SOFIA) and a scientific programmer. I will discuss the type of science done at SOFIA and the virtues and differences of a non-academic position out of graduate school.

Simulating Planetesimal Formation in the Kuiper Belt and Beyond
Rixin Li, University of Arizona
A critical step in planet formation is to build super-km-sized planetesimals in protoplanetary disks. The origin and demographics of planetesimals are crucial to understanding the Solar System, circumstellar disks, and exoplanets. I will overview the current status of planetesimal formation theory. Specifically, I will present our recent simulations of planetesimal formation by the streaming instability, a mechanism to aerodynamically concentrate pebbles in protoplanetary disks. I will then discuss the connections between our numerical models and recent astronomical observations and Solar System explorations. I will explain why all planetesimals likely formed as binaries.
