Dark Energy, Dark Matter, and Otters – Prof. Sarah Tuttle (UW)
Channel: Astronomy On Tap Seattle
Date: 29/06/2017

On May 25, 2017 we were joined by Professor Sarah Tuttle* who spoke on "Dark Energy, Dark Matter, and Otters - The universe in three parts," describing among other things her lead role in designing and building the instruments that allow the HETDEX project to measure dark energy. 

Each FREE Astronomy on Tap event features accessible, engaging science presentations on topics ranging from planets to black holes to the beginning of the Universe. Most events have games and prizes to test and reward your new-found knowledge! There is always lots of time to ask questions and interact with the presenters and other scientists who inevitably stick around for the beer.

Speaker Bio
-------------------

* Professor Sarah Tuttle (bio from her webpage)
Sarah Tuttle is primarily an instrumental astrophysicist who dabbles in observations of nearby galaxies. Her work is focused on novel approaches to observing faint and diffuse matter, as well as techniques supporting integral field spectroscopy. Her past work involved using UV spectroscopy to try and detect the intergalactic medium. She was also the instrument scientist for VIRUS – a massively replicated spectrograph currently coming online at McDonald Observatory to detect dark energy at intermediate redshifts. Professor Tuttle’s current interests include novel materials for astronomical gratings and filters, as well as approaches to bring polarimetry (and spectropolarimetry) to small telescopes.
