The Structure and Evolution of Early-Type Galaxies: A Lensing Perspective
David Rusin (U. Penn.) - October 8 at 12:00 noon
Gravitational lenses represent a unique sample of galaxies: they are
mass-selected, dominated by early-type morphologies, and naturally span
the redshift range 0 < z < 1. Moreover, the observed properties of lensed
images are sensitive to the galaxy mass distribution, and the geometry
provides a model-independent measurement of the projected mass. Lenses are
thus powerful tools for investigating the structure and evolution of
early-type galaxies. I will review recent progress on these fronts using
individual lenses, and introduce statistical methods to constrain the
radial mass profile in early-type galaxies, trace the evolution of their
stellar populations, and address the relationship between luminous and
dark matter on galaxy scales.
The seminar will be held in 501 Campbell Hall.
