Circumgalactic Gas Modeling & Effective Science Education

Dr. Cameron Hummels (Caltech)
October 17, 2017 - 4:00pm


Breaking all rules of academic presentation convention, I will give a talk on two
distinct and disparate topics: the physics of the circumgalactic medium and
public education in the form of non-traditional astronomy-based activities.
For the science half of the talk, I will discuss my recent work
at modeling the circumgalactic medium, the tenuous gas surrounding galaxies,
with a focus on the size scale of individual absorbers as probed through the
FIRE and the Tempest simulations, the two highest resolution zoom hydro
simulations produced to date.  On the education side, I will describe the
increased need for all scientists to be pro-active in truly reaching out to
the sometimes science-wary public, along with many tips and opportunities
for doing so effectively, based on my experiences running Caltech and Columbia's
astronomy outreach programs.  Feel free to come to whichever half (or both)
that is relevant to you!
