 Title: Exploring Galactic Gas Flows During Cosmic Afternoon

 Speaker: Prof. David Koo, Univ. of California, Santa Cruz

 Time: 3 PM, Nov. 9 (Wednesday)

 Location: Middle conference room, 3rd floor

 Abstract: 

While inflowing gas is clearly needed during the formation of galaxies, the outflows of gas from galaxies are increasingly recognized as being also critical to explain key properties of galaxies. This talk will describe several of our discoveries that such galactic outflows of cool gas are very common, almost ubiquitous, among strong star-forming, massive galaxies at moderate redshifts from 0.5 to 1.5. This era is during "cosmic afternoon" when average rates of star formation are declining from its peak ("cosmic noon") at redshifts about 2. This talk will also describe our current follow-up, larger, and deeper survey of these galactic winds. Called DEEPwinds, it is being conducted within fields (known as CANDELS), which possess especially deep, multi-wavelength data that richly complement our new spectra and are relevant to wind studies.
