The predictive power of the baryon distribution in galaxy kinematics - Joint Particle/Cosmology Seminar

The orbital speeds of stars and gas in galaxies
are famously faster than expected from the observed mass in baryons, leading to
the inference of cosmically ubiquitous dark matter.  Yet galaxies are not
the incomprehensibly complicated non-linear systems that we expect
from structure formation arguments.  Instead, many of their dynamical
properties are predictable based solely on the observed distribution of
baryons.  I will discuss some examples and the potential implications for
physical theory.
