posted in: Uncategorized | 0

COSMIC THURSDAYS, a series of public and free talks on astronomy. The talks are designed with the general audience in mind. They are fun, easy to understand, and engaging.

  • Date: Thursday, August 22 – 6:30 PM
  • Speaker:  Prof. Brian Siana (Department of Physics and Astronomy, UCR)
  • Place: UC Riverside, Bourns Hall, Room #A265
  • Talk: Galaxies with a Heartbeat: How Rapid Changes Allow Tiny Galaxies to Alter the Evolution of the Universe

We are familiar with big spiral galaxies like our own Milky Way and elliptical galaxies. But much of the evolution of the early universe was driven by much smaller galaxies. These “dwarf” galaxies are not just scaled down versions of bigger galaxies.  Instead, they are subject to rapid transformations from winds and energy from stars and supernovae.  In this talk, Prof. Brian Siana will discuss what we know about dwarf galaxies, his group’s research to understand these rapid transformations, and the implications for dwarf galaxies’ effects on the universe.
