"What's a Galaxy?"

Speaker's website »

This seems like a simple enough question.  Recently, the question has
referred to the difference between dwarf galaxies and star clusters.  Instead,
I will look at the subtle back and forth over the last decades in our
understanding of galaxies and clusters of galaxies.  I will give a simple
definition of "galaxy",  show the phenomenology behind the
transition and speculate on the physical mechanisms that are responsible.
