Data Analysis
The OzSTAR Supercomputer
PRESS observational data are processed on the OzSTAR Supercomputer at Swinburne University of Technology. OzSTAR supports the ARC Centre of Excellence in Gravitational Wave Discovery (OzGrav) and operates as a national facility for the astronomy community through the GPU Supercomputer for Theoretical Astrophysics Research (gSTAR) program, which receives funding from Astronomy Australia Limited.
We are very grateful to the Swinburne High Performance Computing (HPC) support team for granting our project 70 TB of storage to support the development and verification of our data reduction pipeline. The advice and guidance of the Swinburne HPC support team also greatly helped us to optimize our usage of the OzSTAR supercomputer.
The beta version of the PRESS data reduction pipeline utilises the Polarimetric Calibration Pipeline, which is based on the PSRCHIVE software library. After it is fully demonstrated and verified, the components of this pipeline will be integrated into the single-pulse pipeline of the MeerTime 1000 Pulsar Array project.
Data Analysis Developments
As part of our pioneering effort to better understand pulsar emission physics, we develop new signal processing algorithms for polarimetric calibration, Radio Frequency Interference mitigation, statistical analysis, and data visualisation. The novel tools that we develop are described and documented here.
