Damping of Primordial Gravitational Waves from Generalized Sources
James B. Dent, Lawrence M. Krauss, Subir Sabharwal +1
It has been shown that a cosmological background with an anisotropic stress tensor, appropriate for a free streaming thermal neutrino background, can damp primordial gravitational…
Schrodinger Picture of Quantum Gravitational Collapse
Tanmay Vachaspati
The functional Schrodinger equation is used to study the quantum collapse of a gravitating, spherical domain wall and a massless scalar field coupled to the metric. The approach in…
Gravitational Lensing by Cosmic String Loops
Andrew A de Laix, Tanmay Vachaspati
We calculate the deflection of a light ray caused by the gravitational field of a cosmic string loop in the weak field limit and reduce the problem to a single quadrature over a ti…
Galactic Cosmic Strings as Sources of Primary Antiprotons
Glenn D. Starkman, Tanmay Vachaspati
A possible signature of a class of superconducting cosmic strings trapped in the Milky Way plasma is the emission of low energy antiprotons due to baryon number violating processes…
Big Bang Nucleosynthesis Constraints on Primordial Magnetic Fields
Peter. J. Kernan, Glenn D. Starkman, Tammay Vachaspati
We reanalyze the effect of magnetic fields in BBN, incorporating several features which were omitted in previous analyses. We find that the effects of coherent magnetic fields on t…
Electroweak String Configurations with Baryon Number
Tanmay Vachaspati, George B. Field
In the context of electroweak strings, the baryon number anomaly equation may be reinterpreted as a conservation law for baryon number minus helicity. Since the helicity is a sum o…
