title: Parkes observations for project P892 semester 2015OCTS

description: SUPERBx is an extension to the SUPERB survey which looks at the highest Galactic latitudes in a search for fast radio bursts (FRBs). Recent results show that there is a strong latitude dependence to FRB detectability so SUPERBx will search above 25 degrees in Galactic latitude. It will use optimised GPU codes to search for pulsars and fast radio bursts (FRBs), making discoveries in real time. Handling our data as it comes in is essential for the SKA Phase I era so this work applies directly to the high-data rates of next generation telescopes. The FRBs discovered will have much more associated information than all previous detections. Firstly the discovery lag will be ~1 second, rather than months/years. The Parkes observations will be shadowed by other radio telescopes (Molonglo, GMRT, MWA) to allow, for the first time, localisation of FRBs, and a host of optical and high-energy telescopes will then be triggered as appropriate. This is key for identifying FRB host galaxies, so as to solve the mystery of their progenitors.

title: Parkes observations for project P455 semester 2015OCTS

description: This project is to continue timing and profile studies of the first double-pulsar system, a unique laboratory for gravitational physics. The main aims of this proposal are to provide the strongest tests to date for general relativity and to measure for the first time the moment-of-inertia of a neutron star. Additionally, we will determine the system geometry and map the pulsar beams via geodetic precession.

description: XSS J1227-4859 is the second "Transitional" pulsar binary system discovered in the galactic field. We plan to continue our campaign of observations at 50cm, 20cm, and 10cm with the aims of: (i) discriminating the various proposed mechanisms responsible for the orbital variations seen in the system; (ii) studying the time evolution and the nature of the radio eclipses; (iii) investigating the nature of the gamma-ray emission from the binary; (iv) determining the critical X-ray luminosity above which the pulsed radio emission disappears;  (v) constraining the geometry of the emission from the system in the radio, X-ray and gamma-ray bands.

title: Parkes observations for project P737 semester 2015OCTS

description: Pulsar observations using the Parkes radio telescope have led to some of the most exciting astronomical results in the last few years.  The aim of this proposal is to carry out tests of the new backend instruments which cannot be carried out during standard maintenance periods. High precision pulsar timing experiments require cross-coupling in the feed to be measured.  This can only be done using observations of PSR J0437-4715 from rise-to-set.  We propose to undertake such observations and make the results available for any users of the telescope.

title: Parkes observations for project P885 semester 2015OCTS

description: We propose to observe 1E 1547.0-5408 weekly, one of two magnetars
known to currently emit radio pulsations, to track its rotation,
flux density, and polarisation. Less frequently we will monitor
PSR J1622-4950 and XTE J1810-197, which used to emit radio pulsations,
to be on the lookout for their revival. After years with unsteady
radio emission, 1E 1547.0-5408 is now detected 100% of the time,
allowing us to obtain a continuous record of its torque which
illuminates the continued release of magnetic energy in the neutron
star. 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: Since the year 2005, the Parkes Pulsar Timing Array (PPTA) project has been placing ever more stringent constraints on the amplitude of a gravitational wave background signal.  Our most recent constraints rule out the standard models for galaxy formation and black hole evolution.  It is essential for the PPTA project, its Northern Hemisphere counterparts and key science projects on MeerKAT and the SKA to know the amplitude of the expected gravitational wave signal. We therefore propose to observe our most precisely timed pulsar, PSR J1909-3744, regularly in order to either obtain the lowest bound possible before MeerKAT and the SKA are commissioned or to identify the characteristic gravitational wave signal in the data set for this single pulsar.

title: Parkes observations for project P456 semester 2015OCTS_BPSR_01

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 gravitational waves until they are finally detected. Continued Parkes observations will remain valuable until the first stage of the SKA is able to offer the same sensitivity as Parkes and the same observing time. 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 P860 semester 2015OCTS_BPSR_01

description: 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. Currently, 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.

title: Parkes observations for project P863 semester 2015OCTS_BPSR_01

description: In this proposal we request observations from the Parkes radio telescope to survey time variability in the radio emission from a sample of pulsars. The aim is to elucidate different phenomena occurring in the pulsars' magnetospheres.  We have chosen a sample of ten pulsars that exhibit various characteristics of the state-changing phenomenon (some are moding pulsars and some are intermittent pulsars).   We plan to use the dual-band receiver that will simultaneously provide us with information at widely separated frequency bands.

title: Parkes observations for project P888 semester 2015OCTS_BPSR_01

description: Erratically-emitting neutron stars like Rotating Radio Transients (RRATs), represent approximately 3% (and increasing) of radio-emitting pulsars as they are found via searches of archival and current pulsar surveys. The sporadic emission from these sources makes them difficult to study and nearly all information about the properties of the objects is the result of dedicated monitoring and timing programs at Parkes telescope. This project represents an effort to obtain accurate timing solutions and polarization profiles of a sample of sparse-emitting pulsars. We will monitor and time 6 sources to determine basic RRAT properties including spin period, spin period derivative, and polarization properties. Thus enabling us to identify physical causes for the extreme emission, enable high-energy follow-up observations, deduce how these pulsars are related to the general pulsar and magnetar populations, and explore the distribution of extreme radio intermittence in neutron stars.

title: Parkes observations for project P789 semester 2015OCTS_BPSR_01

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, 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.
This project also makes use of all beams of the 21-cm receiver to search for transient radio burst of extragalactic origin at the same time as performing timing observations.

title: Parkes observations for project P574 semester 2015OCTS

description: We request time to observe 230 pulsars on a regular basis in order to provide the accurate ephemerides necessary for the detection and characterisation of gamma-ray pulsars with the Fermi satellite. The main science goals are to increase the number of known gamma-ray pulsars (both radio loud and radio quiet), to determine accurate pulse profiles, and to characterise their high energy (phase-resolved) spectra. In the radio, the observations will also allow us to find glitches, characterise timing noise, investigate dispersion and rotation measure variability, and enhance our knowledge of single pulse phenomenology. To date, we
are (co-)authors on 48 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of students from the Bordeaux group and Stanford and are in remain in active use (detailed within).

title: Parkes observations for project P626 semester 2015OCTS

description: We plan to search for pulsed radio-emission in transient "magnetar" sources (already known or yet to be discovered at the time of submission of this proposal), during the phase following an X-ray outburst, i.e. after an increasing of the X-ray flux of the magnetar of a factor at least 10 with respect to the normal emission. Observations of past years showed that radio-emission has been triggered in transient magnetars in at least 4 cases over 11 after this kind of outburst. However, in several cases, no prompt radio observation had been planned, preventing to investigate the phase of onset of the radio emission. A more precise understanding of this phase may greatly contribute to clarify the nature of the radio-emission mechanism in magnetars and the relation between them and the canonical radio pulsars. A similar program of NAPA observations has been planned by our group at various X-ray satellites and ground-based infrared and optical telescopes, thus allowing a multi-wavelenght investigation of the sources. To fully exploit our multi-wavelength data sets, we also intend to perform simultaneous X-ray and radio follow-ups of magnetars for which a trigger of this programme was obtained during current or previous semester.

title: Parkes observations for project P898 semester 2015OCTS

description: Strader et al. (2015) have identified within the error box of the
gamma-ray source 3FGL J1417.5-4402 an extremely interesting optical
and X-ray system in a 5.4-day orbit that they interpret as a massive
neutron star (NS) with a giant companion currently undergoing
accretion. We have discovered at Parkes a radio millisecond pulsar
that is clearly the NS in this binary. This indicates that the
system is not currently accreting, although there are very likely
outflows from the companion. Our early radio results, together with
published optical data, suggest a mass ratio of about 6; for a
plausible companion mass, this would imply a massive NS, ~2.0 Msun.
Here we propose 1.4 GHz timing observations of PSR J1417-4402 in
order to precisely measure several characteristics of this system
that appears to be unique in the Galactic disk, including constraining
its NS mass.

title: Parkes observations for project P896 semester 2015OCTS

description: While pulsars are well known to emit over a wide range of frequencies, the total bandwidth over which the emission is correlated and the pulse-to-pulse variability of this bandwidth are poorly understood.    Given this uncertainty, it is unsurprising that the effects of this variability on precision pulsar timing are unknown.     We therefore propose to answer three questions about the broadband nature of pulsar emission: 
1) Over what bandwidths are individual pulses correlated?
2) Does this bandwidth vary across the pulsar population? 
and 3) How does this bandwidth affect pulsar timing?
To answer these questions, we propose to study 5 bright pulsars that span the neutron star population, exhibit a diverse range of pulsar phenomenology. We request 5 hours of Parkes observation time to conduct simultaneous multi-frequency single-pulse observations jointly with the MWA    These measurements will be used to construct better empirical models for pulsar emission, test theoretical predictions, and assess the effects of broadband variability on pulsar timing measurements.
