Probing for primordial black hole candidates in exoplanet search data
Paul Halpern, Erik Cauley, Max Stoltzmann +1
We have sifted through astrophysical data collected by various radial velocity and gravitational microlensing searches for exoplanets with the goal of identifying potential signs o…
Energy conditions in a modified Brans-Dicke theory
Hootan Amani, Paul Halpern
We consider a modified version of Brans-Dicke theory (MBDT) in four dimensions obtained by applying the induced matter method of Wesson to a 5D generalized Brans-Dicke theory. In 5…
Energy Distribution of a Charged Black Hole with a Minimally Coupled Scalar Field
Paul Halpern
Using three different energy-momentum complexes, the Einstein, Landau-Lifshitz, and Papapetrou prescriptions, we calculate the energy of an electrically charged black hole exact so…
Energy of the Taub Cosmological Solution
Paul Halpern
We calculate the total energy of Taub's 1951 exact solution for a Bianchi type IX geometry using several different energy-localization procedures, including the prescriptions of Ei…
Energy Distribution of Black Plane Solutions
Paul Halpern
We use the Einstein energy-momentum complex to calculate the energy distribution of static plane-symmetric solutions of the Einstein-Maxwell equations in 3+1 dimensions with asympt…
The Mixmaster Universe in Five Dimensions
Paul Halpern
We consider a five dimensional vacuum cosmology with Bianchi type-IX spatial geometry and an extra non-compact coordinate. Finding a new class of solutions, we examine and rule out…
