title: Parkes observations for project P456 semester 2018OCTS_13

description: The Parkes Pulsar Timing Array (PPTA) project has three primary goals: (a) detection of gravitational waves from astronomical sources, (b) establishment of a pulsar timescale, and (c) improvement of our understanding of Solar-system dynamics. The PPTA is the oldest of three international pulsar timing groups. We have the smallest telescope and the smallest group, but the best measurements and the best results. Our bound on the strength of the incoherent gravitational wave background is the only bound which significantly constrains theoretical models. We have maintained our leading position because: we have the southern sky; we have a small but well-focussed group; we have the best-calibrated receivers; and we have been able to observe with an almost regular cadence of 15 to 20 days at three different wavelengths. With this proposal we aim to maintain our pre-eminent position in the field.

Unlike most observing proposals, this is a continuing proposal for which the observations will continue to improve bounds on ultra-low-frequency gravitational waves until they are finally detected. Continued Parkes observations will remain valuable at least until the first stage of the SKA is able to improve on our sensitivity and observing cadence. Even after the gravitational wave background is detected we will want to continue observations in support of the nascent field of gravitational wave astronomy!

title: Parkes observations for project P885 semester 2018OCTS_03

description: We propose to observe PSR J1622-4950 and 1E1547.0-5408 weekly, two
of three magnetars known to currently emit radio pulsations, to
track their rotation, flux density, and polarisation. Less frequently
we will monitor XTE J1810-197, which used to emit radio pulsations,
to be on the lookout for its revival - as recently happened with PSR
J1622-4950, which turned on in 2017 after more than 2 years dormant!
These observations yield a continuous record of torque, illuminating
the continued release of magnetic energy. Our broader aims are to
develop a better understanding of the dynamical behaviour of magnetar
magnetospheres, and to establish the conditions under which radio
emission takes place therein, in addition to characterising their
variable radio emission in order to place constraints on the emission
mechanisms, which in at least some respects differ from those of
ordinary pulsars.

description: This proposal relates to time purchased by the Chinese Academy of Sciences for Parkes follow-up confirmation and timing of FAST discoveries.  As the observing time has been purchased this proposal (and the related PX500) does not require TAC grading.  The primary reason for submitting a proposal is to ensure an outreach statement and that the proposal is entered into OPAL for the data archive to access. The Chinese team have two time requests. The time scheduled for the first (PX500) will be allocated in blocks of 24 hours and the data will become available in the data archive with an 18 month embargo period.  The second type of time (relating to this proposal) will be scheduled in shorter blocks and the data archived with a 10 year embargo.

title: Parkes observations for project P996 semester 2018OCTS_08

description: We propose to measure the polarisation of ~200 pulsars (~100 this semester) using the Ultra-Wideband Low (UWL) receiver to investigate the structure of the Galactic disk magnetic field in and between distant spiral arms. Previous Parkes pulsar observations have revealed field reversals in nearby arm and interarm regions. We wish to exploit the greater sensitivity of the UWL receiver to extend this to more distant regions, thereby allowing us to distinguish more clearly between different models for the structure of the disk field. This work will have important implications for theories for the generation of Galactic magnetic fields and for other areas, e.g., cosmic-ray physics, which depend on a knowledge of the large-scale Galactic magnetic field for their interpretation.

title: Parkes observations for project P789 semester 2018OCTS_05

description: Recently there has been great success at Parkes discovering millisecond pulsars (MSPs), a class that includes some of the most interesting and scientifically valuable pulsars known. In the last few years, we have discovered more than 40 MSPs though the High Time Resolution Universe Survey (P630) and Fermi searches (P675/P814). Here we propose to carry out precision timing of these sources to fully exploit these discoveries. Additionally, we continue to study the most significant of the discoveries from the Parkes Multibeam Pulsar Survey (P268). 
To maximise scientific impact, we have combined the most important sources from various previous proposals into this project, reducing total observation time required and easing the burden on the scheduler.

title: Parkes observations for project P971 semester 2018OCTS_14

description: We propose timing observations of the relativistic pulsar - white-dwarf binary PSR J1141-6545. This unique system offers access to a wide range of physics, from relativistic phenomena through pulsar emission cone studies, to the structure and distribution of interstellar plasma along our line-of-sight. The recently installed Parkes Ultra Wide Band Low Frequency (UWL) receiver has opened up the possibility of performing first-ever studies of its orbital dynamics at high temporal resolution and study of the effects of the intra-binary medium on the dispersion and polarisation of the pulse profile. Our analysis of data obtained to date suggests that the pulsar would precess away from our line-of-sight in the next 3-5 years. Hence, regular observations are crucial to maximizing its science outcome
