Keck Observatory Donor Salon: Unveiling Outflowing Galactic Winds with the Keck Cosmic Web Imager
Dr. Alison Coil
Associate Dean in Division of Physical Sciences, Professor of Physics
University of California at San Diego
In this talk, research will be presented that Dr. Coil and collaborators have been leading on extremely fast outflowing galactic winds being ejected from compact, starburst galaxies. Such outflows are thought to be a key process in galaxy evolution, specifically in shutting down star formation and creating quiescent galaxies, but the details of how this process works – and how common it is – are still unknown. Using the Keck Cosmic Web Imager, the team has imaged several large-scale outflowing winds, and discovered the single largest galactic outflow ever observed. Dr. Coil will show data on these galaxies from other Keck instruments, including HIRES and ESI, and discuss what can be learned from different instruments. In addition, Alison will discuss exciting upcoming James Webb Space Telescope galaxy observations the team is eagerly awaiting.
The staff and management of the W. M. Keck Observatory wish to offer our deepest gratitude to our Astronomy Talk Series sponsors, Rob and Terry Ryan.
