Detecting gravitational waves from coalescing binaries of neutron stars and black holes

We focus on the research area of gravitational wave signal processing, high-performance supercomputing, and multi-messenger astronomy including gravitational waves using data from ground-based interferometric gravitational-wave detectors.

Summary of the project

It is an exciting time for gravitational wave research.  The first gravitational wave signal from merging binary black holes was detected in September 2015 during the first science run of the Laser Interferometer Gravitational-wave Observatory (LIGO) in the United States.  This not only confirmed Einstein’s theory on gravitational waves but also marked the beginning of a new era in astronomy.   The second LIGO science run is scheduled in October 2016. Up to tens of new detections are expected from this run and many more are expected in the next few years.

We are leading one of the online detection pipelines for gravitational waves from coalescing binaries of black holes and neutron stars using detector data.  Our group was actively searching for gravitational waves online using the LIGO data during the first science run where the first discovery was made. The group will continue to be actively involved in detecting gravitational waves in science runs of LIGO as well as the Virgo detector in Europe.

The prospect student is expected to work on some of the following aspects:

  • Directly involving in the online real-time searches for gravitational wave signals in LIGO/Virgo detector data
  • Speed up of gravitational wave searches using high-performance supercomputing techniques including the use of Graphics Processing Units (GPUs)
  • Testing Einstein’s theory of general relativity using data of discovered gravitational wave events
  • Optimizing future detector network to maximize the scientific potential of gravitational wave astronomy
  • Analytically and numerically investigating new binary black hole merger models with potentially observable electromagnetic counterpart

Eligibility criteria

General UWA PhD entrance requirements can be found on the Future Students website.

Requirements specific to this project:

  • We are looking for highly motivated applicants with interest in gravitational wave search and multi-messenger astronomy including gravitational waves. Background with astrophysics and/or high-performance computing is desirable. For applicant with interest in search pipeline development, software programming experience using C/C++, Python are required, and programming ability for Graphics Processing Units (GPUs) is a plus.
