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.

Using every photon to learn about the physics of solar plasmas

Phil Judge, High Altitude Observatory, Boulder CO.

The Sun has traditionally been the Rosetta Stone that can overcome the gap in regimes between laboratory and astronomical plasmas.   Theories applicable in the laboratory may not readily apply to solar plasmas, and vice-versa. Yet we still face challenges in understanding how the observable plasmas are produced, and why the magnetic field threading and energizing them must globally reverse every 11 years. I will give a general overview of currently pressing problems in solar physics, followed by two specific examples: one concerning the physics of flares through infrared spectroscopy and polarimetry, the other concerning how we might wring every last ounce of information from the emitted photons. Along the way I will introduce the NMSU-operated Dunn Solar Telescope, the new DKIST, Parker Solar Probe and Solar Orbiter, and suggest how we might take advantage of these new facilities to make lasting progress.
