Public Lectures

Ever wonder what goes on at SLAC National Accelerator Laboratory? The SLAC Public Lecture Series is your chance to find out! Every other month, SLAC opens its doors to the local community for an evening lecture highlighting the cutting-edge science happening at the laboratory. From the nanotechnology of diamonds to the latest Higgs Boson discoveries, SLAC public lectures provide non-scientists with a unique insight into the workings of our universe.

Galaxy Clusters and the Life and Death of the Universe

Public Lecture Poster - Galaxy Clusters and the Life and Death of the Universe
Description:

The distribution of galaxies in the universe is patchy. Galaxies are bound together in clusters made of stars, hot gas and invisible dark matter. These galaxy clusters are part of a cosmic web of filaments, nodes and empty voids that has been building up over 13 billion years. How do we observe this structure, and how do we use gravitational lensing and satellite X-ray observations to measure its mass? How do galaxy clusters trace the past expansion of the universe and reveal our future? This lecture will highlight data from the Dark Energy Survey, today’s largest cosmic survey, to answer these questions.

 

About the speaker:

SLAC Research Scientist Eli Rykoff has been weighing the universe for over a decade. He received his PhD from the University of Michigan in 2005, where he built a worldwide network of automated telescopes for following gamma-ray bursts, the most energetic explosions in the universe. After graduating, he transitioned to studying galaxy clusters, which evolve over billions of years rather than fractions of seconds, and did postdoctoral research at the University of California, Santa Barbara and Lawrence Berkeley National Laboratory. Rykoff moved to SLAC in 2012, where he works on galaxy cluster finding and other studies for the Dark Energy Survey and the upcoming Large Synoptic Survey Telescope. He also develops educational astronomy apps for the iPhone and iPad, including CosmoCalc, a full-featured cosmological calculator, and GravLens3, a gravitational lens simulator.

 

Lecture will be held at the Panofsky Auditorium (the Science and User Support Building)
