Parkes observations for project P860 semester 2015OCTS_BPSR_01
This is a request for observing time for the initial follow-up of pulsar discoveries from the low-latitude Galactic plane section of the HTRU survey (P630). We have already discovered 66 pulsars from 55% of processed data. Extrapolation and population synthesis show that the Galactic plane survey will result in at least a further 60 discoveries. Cu... morerrently, with data processing on-going employing all available computing resources, we expect about 15 new discoveries per semester.
The discovery of pulsars is just a ?rst step and interesting science can usually only be revealed when a follow-up timing campaign is carried out. One year of initial timing is the minimal timespan required to fully-characterise any newly-discovered pulsars, essential for deriving pulsar parameters such as the characteristic age, magnetic ?eld strength, spin-down rate, as well as to detect any unexpected behaviour of the pulsar which might result from emission instabilities.
This follow-up timing project is necessary for identifying any individual interesting pulsar systems discovered from the HTRU Galactic plane survey. Since all of the pulsars on the observing list here are followed-up for the ?rst time, they will produce completely new and exciting results. In addition, this timing project will enable a large-scale examination of the Galactic plane pulsar population, exploring the true boundaries of pulsar phase space. Given the large number of discoveries expected and the long integration length required, this dedicated follow-up timing campaign is vital for achieving our science goals. less

P860 - Initial Follow-up of Pulsar Discoveries from the HTRU Galactic Plane Survey
Pulsars are the collapsed cores of once-massive stars. They are giant flywheels in the Universe and the fastest one can spin up to an incredible 700 times per second. At the same time they have extremely strong magnetic field up to multiple quadrillions of times larger than that of the Earth. The Parkes telescope has discovered more pulsars than al... morel the rest of the telescopes put together. Once discovered and followed-up, these pulsars allow scientists to test theories of gravity, search for the signatures of massive black holes spiralling together and help determine how nuclear matter is bounded together. We hope to understand these exotic stars and to use them as a probe to study the fundamental physics that governs the Universe. less
