A1.00001: First Look from the Hobby-Eberly Telescope Dark Energy Experiment Invited Speaker: Prof. Karl Gebhardt We have started a large observational program to quantify the expansion of the universe and understand the nature of dark energy. The universe is expanding at an accelerated rate, currently not understood, and might signify new physics, or a different model of the Big Bang, or something completely unexpected. HETDEX was started over 10 years ago to address dark energy; we are just now starting the observational program. I will update on the latest thinking and potential impact from HETDEX.

A1.00002: Neutrino Oscillations: From Discovery to Precision Measurements Invited Speaker: Prof. Lisa Whitehead Koerner The neutrino is one of the elementary particles which make up the universe. Neutrinos are produced in the fusion reactions inside the sun and other stars, by natural radiation inside the earth, by supernovae, and by charged particles bombarding Earth’s atmosphere. Despite their abundance, they interact very rarely with matter, and sensitive detectors with large masses are required to observe their interactions. Neutrinos come in three types, called flavors, and experimental observations have established that neutrinos undergo flavor oscillations as they propagate due to quantum mechanical mixing between the mass states and flavor states. In this talk, I will discuss the experiments that discovered neutrino oscillations and describe what we hope to learn from current and future experiments. [Preview Abstract] |
