Dark Matter in the Solar System
X. Xu, E. R. Siegel
We determine the density and mass distribution of dark matter within our Solar System. We explore the three-body interactions between dark matter particles, the Sun, and the planet…
What Millisecond Pulsars Can Tell Us About Matter In The Galaxy
E. R. Siegel
I demonstrate that precision timing of millisecond pulsars possess the capabilities of detecting the gravitational effects of intervening galactic substructure. This analysis is ap…
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…
Dark Matter on the Smallest Scales
E. R. Siegel, G. D'Amico, E. Di Napoli +5
This work investigates the dark matters structures that form on the smallest cosmological scales. We find that the types and abundances of structures which form at approximately Ea…
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…
Cosmological Structure Formation Creates Large-Scale Magnetic Fields
E. R. Siegel, J. N. Fry
This paper examines the generation of seed magnetic fields due to the growth of cosmological perturbations. In the radiation era, different rates of scattering from photons induce…
