Parkes observations for project P860 semester 2018OCTS_05
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 are in the final stages of our first pass processing with our periodicity search algorithm, and have already discovered 106 previously unknown pulsars. We expect that processing should be co... moremplete within the 2018OCTS semester. Extrapolation and population synthesis shows that the Galactic plane survey should result in a further 5 discoveries.
Interesting science can usually only be derived from a new pulsar after confirmation and a follow-up timing campaign is carried out. One year of initial timing is the minimum 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 interesting pulsar systems discovered from the HTRU Galactic plane survey. Since all of the pulsars on the observing list here are being followed-up for the first 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 parameter 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
