The Dark Galaxy Problem and the Effects of Substructure on Gravitational Lenses
R. Benton Metcalf
I argue that the cold dark matter (CDM) model requires that even within a few kpc of the center of a galactic halo a significant fraction (greater than a few percent) of the surfac…

Prospects for the Lensing of Supernovae
R. Benton Metcalf
Observations of high redshift type Ia supernovae (SNe) will enable us to probe the structure of galaxy halos and the composition of dark matter. The future prospects for this field…

The Detection of The Gravitational Lensing of Supernovae
R. Benton Metcalf
The weak gravitational lensing of high redshift type Ia supernovae has the potential of probing the structure of matter on galaxy halo scales. This is complementary to the weak len…
