  报告题目:The Cool Gas Reservoir Cycle of Galaxies

  摘    要:The cycle of gas into and out of galaxies governs their observable evolution. Both accretion of gas onto galaxies and expulsion of gas from galaxies are driven by a variety of processes, whose relative importance is still not well understood. In this talk, I will give an overview of my research aimed at understanding some of these processes, including studying the disk-halo interface of the Milky Way, the connection between star formation and the gaseous content of early-type galaxies, and the search for extended HI disks as a source for missing baryons.

  报 告 人:Heather Alyson Ford (NRAO)

  报告人简介:Alyson is the Lead Scientist for the NRAO 140ft Telescope in Green Bank, which is currently operating as the Green Bank Earth Station for the Spektr-R satellite. Alyson's research has focused primarily on the gaseous content of galaxies and the processes that shape this gas, including star formation, stellar feedback, and accreting gas. To study these topics, she has performed observations at wavelengths ranging from the UV through the optical to the radio. Her other interests include instrumentation, passive, bistatic and active radar, space debris, and image processing.
