Testing general relativity with black hole-pulsar binaries

Physical Review D, 2018
Binary pulsars allow us to carry out precision tests of gravity and have placed stringent bounds on a broad class of theories beyond general relativity. Current and future radio telescopes, such as FAST, SKA, and MeerKAT, may find a new astrophysical system, a pulsar orbiting around a black hole, which will provide us a new source for probing gravity ...

Random Number Generation from Pulsars

Pulsars exhibit signals with precise inter-arrival times that are on the order of milliseconds to seconds, depending on the individual pulsar. There are subtle variations in the timing of pulsar signals. We show that these variations can serve as a natural entropy source for the creation of Random Number Generators (RNGs).

Testing General Relativity with Pulsar Timing Arrays

Proceedings of the Wisconsin Space Conference, 2012
Pulsar timing arrays are a promising tool for probing the universe through gravitational radiation. A variety of astrophysical and cosmological sources are expected to contribute to a stochastic background of gravitational waves (GWs) in the pulsar timing array (PTA) frequency band.

Improving pulsar search efficiency in next-generation pulsar surveys with artificial intelligence

Monthly Notices of the Royal Astronomical Society
ABSTRACT Pulsar searching with next-generation radio telescopes requires efficiently sifting through millions of candidates generated by search pipelines to identify the most promising ones. This challenge has motivated the utilization of artificial intelligence (AI)-based tools.

Increasing the detectability of long-period and nulling pulsars in next-generation pulsar surveys

Publications of the Astronomical Society of Australia
Abstract Recent discoveries of multiple long-period pulsars (periods ${\sim}10\,$ s or larger) are starting to challenge the conventional notion that coherent radio emission cannot be produced by objects that are below the many theorised death lines.
