Featured Presentation

The Galactic Ecosystem

By Crystal Martin, Professor of Physics, UC Santa Barbara


For decades, the galactic baryon deficit baffled astronomers. Adding up the mass of stars and gas in galaxies produced a total baryonic mass that was significantly less than expected. Dr. Martin will discuss an emerging solution to this cosmic accounting error, the circumgalactic medium. This nearly invisible gas surrounds galaxies, and our observations show this baryon reservoir is an integral part of the galactic ecosystem. She will show how scientists measured the rotation of the circumgalactic gas and discuss how this property shapes the growth of galactic disks.
