Supernova Cosmology
Abstract:
Supernovae
have developed into a versatile tool for cosmology.
Their impact on the cosmological model has been profound
and led to the discovery of the accelerated expansion.
The current status of the cosmological model as perceived
through supernova observations will be presented. Supernovae
are currently the only astrophysical objects that can
measure the dynamics of the cosmic expansion during
the past eight billion years. Ongoing experiments are
trying to determine the characteristics of the accelerated
expansion and give insight into what might be the physical
explanation for the acceleration.
