Pulsars Excerpt

This is an excerpt – at the moment a thumbnail sketch- from a commissioned piece for Audiograft 2017 and currently a work in progress. This sound work will be a performance of recorded sound heard via multiple hand held speakers in amongst an audience. It will focus on sound from pulsars found in and outside our galaxy. Different rhythmic pulses heard in the work will correspond to the rotations of different pulsars. Jodrel Bank research describes a pulsar as,
‘ …a highly magnetized neutron star, with a radius of 10-15 km. Radiation is beamed out along the magnetic poles and pulses of radiation are received as the beam crosses the Earth.’

The distance between the listener and the original source creating the energy we eventually hear is extreme. Although the amount of light years varies for each different pulsar heard in the work, in the course of attempting to think about these distances our imagined landscape is extended, via the sound.

One of the pulsars heard in the work will be the Vela Pulsar.
‘Vela Pulsar -supernova remnant PSR B0833-45 is the debris of the explosion of a massive star about 10,000 years old.’

This piece progresses the work I have done in the practical research for my PhD where I sonified live streamed alpha muons (cosmic rays) to an attic in Bristol. (You Are Here – 2013 http://vimeo.com/111437221). The energy source of the alpha muons was estimated to be from the galaxy Centaurus A or NGC – 5182 and situated 11 million light years from earth.
