Alternative characterization of a black hole boundary
Pravin Kumar Dahal
After reviewing the shortcomings of existing definitions used to characterize the boundary of a black hole, we present a new method for its characterization. This definition could…
Polarization rotation and near-Earth quantum communications
Pravin Kumar Dahal, Daniel R. Terno
We revisit polarization rotation due to gravity, known as the gravitational Faraday effect, with a view on its role in quantum communications with Earth-orbiting satellites. In a s…
Trapped region in Kerr-Vaidya space-time
Pravin Kumar Dahal
We review the basic definitions and properties of trapped surfaces and discuss them in the context of Kerr-Vaidya line-element. Our study shows that the apparent horizon does not e…
Properties of space-time in the vicinity of trapped regions
Pravin Kumar Dahal
We investigate the near horizon geometry of the simplest representative of the class of axisymmetric space-times: the Kerr Vaidya metrics. Kerr Vaidya metrics can be derived from t…
Kerr-Vaidya black holes
Pravin Kumar Dahal, Daniel R. Terno
Kerr-Vaidya metrics are the simplest nonstationary extensions of the Kerr metric. We explore their properties and compare them with the near-horizon limits of the spherically symme…
Review of Pulsar Timing Array for Gravitational Wave Research
Pravin Kumar Dahal
Ongoing research on Pulsar Timing Array (PTA) to detect gravitational radiation is reviewed. Here, we discuss the use of millisecond pulsars as a gravitational wave detector, the s…
