Parkes observations for project P1050 semester 2020APRS_17
This is a request for observing time for the initial follow-up of pulsar discoveries from the re-processing of the low-latitude Galactic plane section of the HTRU survey (P630). We have now completed a first pass re-processing of the 60 % of the survey with GPU based coherent acceleration search and template bank search pipelines, and have discover... moreed potential 54 previously unknown pulsars.
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 field strength, spin-down rate, as well as to detect any unexpected behaviour of the pulsar which might result from emission instabilities. This follow-up and timing project is necessary for following up on 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. less

P1050 - Initial Follow-up of Potential Pulsar Discoveries from Re-processing of the HTRU-S LowLat Galactic Plane Survey
Pulsars are the collapsed cores of once-massive stars. They weigh about 1.4 times the mass of our Sun, and spin at rates of up to
an incredible 700 times per second. They also have very strong magnetic fields, up to multiple quadrillions of times stronger than
the Earth's magnetic field. As a pulsar spins, beams of radio waves sweep out from the ... morepulsar's magnetic poles, causing it to act
like a cosmic lighthouse. This produces a regular, pulsing signal which we can detect with radio telescopes like Parkes. Over 2900
pulsars have been found in our Galaxy to date, and more than half of them have been discovered with Parkes.
Pulsars can be useful in many different areas of science, giving us the chance to understand many fundamental questions of
physics. They can be used to test theories of gravity such as Einstein's General Relativity, to look for the gravitational waves from
massive black holes spiralling together in distant space, to study the clouds of dust and gas which fill our Galaxy, or to probe the
structure of the ultra-dense nuclear matter which makes up each pulsar, which is so dense that a teaspoon of it would weigh more
than Mt. Everest. The goal of our project is to study some of the most recent pulsars which Parkes has discovered and to
determine the ways in which each of these new pulsars might be used in order to help answer some of these questions. less
