Astronomy on Tap Atlanta: IceCube, High-Energy Neutrinos, Stellar Astrophysics, & Climate Change

**Speaker #1:**GA Tech Physics Professor Dr. Ignacio Taboada

Title: IceCube and the Birth of High-Energy Neutrino Astrophysics

Summary: IceCube, a neutrino telescope in operation at the geographic South Pole, has enabled a new way to look at the Cosmos: high energy neutrinos. In this presentation I’ll tell you what neutrinos are, why we use them to do astronomy and what are some of the most important discoveries that IceCube has made. It’s not a rap; it’s about the Universe.

Title: When Stellar Astrophysics, Climate Change, and the Bush Administration Walk Into a Bar: The Soon and Baliunas Controversy

Summary: Stars change over time. So does the Earth. And so do people. Join a dramatic re-telling of how two scientists made foundational developments in astrophysics, then turned to climate change denialism while receiving secret payouts, caused half the editors of a scientific journal to resign, and laid the groundwork for political suppression of global warming information within the EPA. Astronomy & public policy & congressional hearings, oh my!
