Gravitational Wave Parity-Violating Strain from Pulsar Glitches in Chern-Simons Modified Gravity
Abhishek Rout, Brett Altschul
We investigate gravitational-wave birefringence from pulsar glitches in dynamical Chern-Simons gravity, a parity-violating extension of general relativity motivated by string theor…
Primordial Gravitational Wave Birefringence in a de Sitter Background with Chern-Simons Coupling
Abhishek Rout, Brett Altschul
In this work, we investigate tensor perturbations in a de Sitter background within the framework of Chern-Simons modified gravity. We introduce transverse-traceless perturbations a…
First Order Axial Perturbation of the Reissner-Nordström Metric in a Possible Parity-Violating Gravity Background
Abhishek Rout, Brett Altschul
We study axial perturbations of Reissner-Nordström black holes within the general framework of parity-violating modified gravity theories. We derive the governing equations for a c…
Exiting Inflation with a Smooth Scale Factor
Harry Oslislo, Brett Altschul
The expectation that the physical expansion of space occurs smoothly may be expressed mathematically as a requirement for continuity in the time derivative of the metric scale fact…
