SUMMARY:The Importance of Being Eccentric\, Physics Department Colloqu
 ium\, Ann-Marie Madigan\, UC Boulder
DESCRIPTION:The Importance of Being Eccentric
\nThe collective gravity
  of bodies on eccentric orbits is key to understanding the evolution o
 f gravitational systems from planets to galaxies. In this talk\, I wil
 l demonstrate wide-ranging implications of these dynamics such as the 
 orbital clustering of icy bodies in the outer solar system (observatio
 ns of which have motivated the Planet 9 hypothesis)\, the feeding of s
 tars and gas to supermassive black holes\, and surprising locations of
  galactic dark matter over-densities.

\nDr. Ann-Marie Madigan is an
  associate professor of Astrophysics and Planetary Sciences at the Uni
 versity of Colorado Boulder. Born in Dublin\, she was one of the first
  students in Ireland to receive an undergraduate degree in Astronomy (
 at the University of Ireland\, Galway). She received her PhD in astron
 omy from Leiden University in The Netherlands and was a NASA Einstein 
 Postdoctoral Fellow at the University of California\, Berkeley.
