The Parkes High Time Resolution Universe (HTRU) Legacy Survey is a comprehensive radio survey of our own Milky Way galaxy and beyond, led by researchers at Swinburne University of Technology. Over a 6 year period (from 2008 to 2013) the survey has, and will continue to, discover astrophysical objects such as pulsars (rapidly rotating neutron stars), rotating radio transients and potentially sources of gravitational waves. The survey has exceptional sensitivity to short-duration extragalactic radio bursts, or millisecond pulsars, resulting from the substational increase in frequency resolution compared to previous surveys.
The high-latitude survey provides a snapshot of the transient sky at 64 microsecond resolution. Further from the galactic plane, the detection rate of pulsars at high-latitudes is expected to decrease. However this high-latitude survey explores a part of the sky that has never been searched for fast transient radio sources. It is possible that many of these radio sources will be from galaxies other than our own.
Survey parameters for the High-latitude Survey:
- Region/sky coordinates: (declination) δ < +10 degrees
- Time of each observation: 270 seconds
- Frequency Band: 340 MHz
- Frequency Bandwidth: 390 kHz
- Sampling time: 64 micro-seconds
- Number of channels: 870
- Data length (samples): 4194304 (4 Megasamples)
- Data per beam: 1.0 Gigabytes
- Total Data: 435 Terabytes
Data is acquired using the Parkes 21-cm Multi-beam Receiver on the CSIRO Parkes Radio Telescope. The Berkeley-Parkes-Swinburne-Recorder (BPSR) system consists of 26 digital spectrometers connected to 13 server class workstations that format the data and write it to disk. Further processing is currently being carried out at the Jodrell Bank Centre for Astrophysics and the Swinburne Centre for Astrophysics and Supercomputing via the Swinburne Pulsar Portal. The project is ongoing with an expected completion date of 2015.
