Probing Dark Matter Substructure with Pulsar Timing
E. R. Siegel, M. P. Hertzberg, J. N. Fry
We demonstrate that pulsar timing measurements may potentially be able to detect the presence of dark matter substructure within our own galaxy. As dark matter substructure transit…
Can Electric Charges and Currents Survive in an Inhomogeneous Universe?
E. R. Siegel, J. N. Fry
Although observations point to the neutrality and lack of currents on large scales in the universe, many mechanisms are known that can generate charges or currents during the early…
Effects of Inhomogeneities on Cosmic Expansion
E. R. Siegel, J. N. Fry
We evaluate the effect of inhomogeneity energy on the expansion rate of the universe. Our method is to expand to Newtonian order in potential and velocity but to take into account…
An estimate of Ω_m without priors
Hume A. Feldman, Roman Juszkiewicz, Pedro Ferreira +10
Using mean relative peculiar velocity measurements for pairs of galaxies, we estimate the cosmological density parameter and the amplitude of density fluctuations . Our…
