Megan Donahue Professor of Physics and Astronomy from Michigan State University will present at JILA Auditorium n Boulder on CU Campus on Monday, February 1, 2016, 4:00pm.
In massive galaxies and in clusters of galaxies, the thermodynamic state of the circumgalactic gas seems to regulate whether or not star formation is occurring in the central galaxy. Megan will discuss the observational evidence for this claim. She will also discuss implications for lower mass galaxies if regulation via precipitation triggering plays an important role in those galaxies as well. Physical predictions of this model will be presented. Learn more and register.
More about Megan: I grew up on a farm near Inland, Nebraska, a town of about 60 people. I attended St Cecilia's, a small Catholic school in Hasting, Nebraska. I have a physics S.B. degree from MIT (1985) and a Ph.D. in astrophysics from the University of Colorado, Boulder (1990). I met my husband Mark Voit, who is also an astronomer, in graduate school. I did post-doctoral research in observational astronomy at the Observatories of the Carnegie Institution of Washington, in Pasadena, California and at the Space Telescope Science Institute (STScI) in Baltimore, Maryland. I was an astronomer for STScI, working on the data archive and the James Webb Space Telescope until 2003, when I started as a professor at Michigan State University in East Lansing, Michigan. I have three children, Michaela, Sebastian, and Angela.
