Parkes observations for project P1348 semester 2024OCTS_04

We have discovered 6 candidate eclipsing binary millisecond pulsar (BMSPs) systems via image-plane searches for steep-spectrum radio sources with periodic variability. The radio emission, short eclipse periods (&lt;1day), and Fermi association suggest they could be spider PSRs. Millisecond pulsations have recently been detected from a similarly identified candidate system. The discovery of millisecond pulsars (MSPs) in these systems would provide insights into the formation and evolution of spider PSRs. It would also improve predictions of the BMSP and MSP populations detectable by upcoming, highly sensitive image-plane surveys at low frequencies using precursors to, and eventually, the Square Kilometre Array (SKA) itself. Finally, 5 of our 6 candidates are also located in the Galactic bulge. If all such systems include MSPs, it would provide further compelling evidence that the Fermi GeV gamma-ray excess is coming from thousands of MSPs.

Long-term project observations for project P1361 semester 2025APRS_04

PSR J1227-6208 is a recycled pulsar in a bianry with a massive white dwarf companion. A recent timing measurement from combined MeerKAT and Parkes observations shows the companion mass to be between 1.2 and 1.5 $M_\odot$, very close to the Chandrasekhar, resulting in potential profound physical implications. However, the timing precision is limited by the DM timing noise. We propose regular monitoring of this pulsar with the Parkes UWL receiver in conjunction with MeerKAT observations during the following four years. The joint monitoring will significantly improve the constraints on the Post-Keplerian parameters, with Parkes observations contributing to constrain the DM noise due to its large frequency bandwidth. These observations will be added to the already existing 11-year-long timing baseline, of which the later 5 years already include high-precision MeerKAT data and Parkes UWL data. After four years of further timing with the inclusion of UWL observatiosn, we predict an uncertainty on the masses smaller than 0.01 solar masses based on simulations. If UWL is not included, the mass uncertanites may saturate on their current values.

Parkes observations for project P1356 semester 2025APRS_09

Magnetars are neutron stars with exceptionally high magnetic fields. From the 30 known magnetars, only six have had radio emission detected so far. The remaining 24 magnetars are generally only searched for radio emission after an X-ray outburst. This added a strong selection bias to whether magnetars are radio loud or not. From the known six radio loud magnetars, we know that the radio emission changes quickly with time and for the magnetar XTE J1810-197, it has been observed that the radio flux increases strongly without an enhancement in X-ray flux. Thus, it remains unclear whether the radio quiet magnetars are in fact radio quiet and the radio X-ray relation appears to be rather complex.
  In this proposal, we propose a regular monitoring campaign of 4 radio quiet magnetars with bi-weekly observations using the Parkes UWL receiver. For 3 of the sources, we will have accompanying X-ray observations and thus, this will give an unique data set to probe the relation between radio and X-ray independent outbursts. Any detection of radio emission, i.e. single pulses or folded profiles, would be a major discovery and help to constrain the emission mechanisms of magnetars. This will also help to improve the understanding of the emission mechanism of fast radio bursts. However, also a non-detection of radio emission will provide upper limits that serve as a baseline before any future outburst of the observed magnetars as well as allow to constrain the formation process of magnetars in contrast to pulsars.

Parkes observations for project P1345 semester 2025APRS_08

This proposal aims to constrain burst rates and spin down properties of a sample of new Rotating Radio Transients (RRATs) discovered with the ASKAP CRAFT Coherent upgrade (CRACO) system. Over the past 12-months of commissioning, CRACO discovered and precisely localised 15 new RRATs, characterised by their sporadic pulses with dispersion measures (DM) consistent with Galactic sources. We request 22.5h of Parkes time split into three 30min observations spanning 6-months for each target. This can help constrain periods and potentially phase-coherent timing solutions given that we already have arcsec-precision interferometric localisations. Our main science goals are: 1) to measure their burst rates, periods, and spin-down properties; 2) to assess their nulling fraction and intermittency; 3) to measure their polarimetric properties and constrain their emission mechanism; 4) to determine if the CRACO RRATs are fundamentally different from the known RRAT population. Some of these goals can be answered even with the detection of a limited number of pulses.

Long-term project observations for project P574 semester 2025APRS_05

We request time to observe 270 pulsars on a regular basis in order to achieve three main science goals. The first is to understand pulsars: how do they spin down and what disrupts this process, how and why their profiles vary with time, whether they precess or have planetary mass companions, in short all the things that make pulsar timing noisier than the perfect clock. Secondly we want to understand the interstellar medium of our Galaxy through repeated monitoring of dispersion measure, rotation measure and flux density variations in conjunction with scintillation parameters. Finally, we provide these data as a community service both to the high-energy community where we have strong collaborative links (particularly to Fermi) and to the radio pulsar astronomers generally through the CSIRO archive. The project is on-going since 2007, we are (co-)authors on 106 papers arising from the P574 data. The data have contributed to the PhD theses of students from Bordeaux, Manchester, Oxford, Stanford, and Swinburne. We are seeking long-term project status with a view to continuing the project into the SKA era.

Parkes observations for project PX600 semester 2020APRS_119

The Galactic Center (GC) is a key target for the radio component of Breakthrough Listen (BL) program. Offering the largest amount of stars in any given direction in the sky, the GC is widely cited as a location believed to harbour advanced civilizations, and it is also the most energetic region in the Milky Way. We aim to conduct BL-GC Survey with Parkes radio telescope for around 350 hours. We will cover the frequency range from 700 MHz to 4 GHz, utilizing the newly installed ultra-wideband receiver. Our team has already leveraged both standard and bespoke tools to construct a flexible software stack to search data for signals of interest. We will look for signals from extraterrestrial intelligence (ETI) by searching for both simple narrow-band signals and complex modulated signals. Along with that, as an ancillary science, we will also search for accelerated pulsars — likely orbiting a supermassive black hole at the centre of the Milky Way Galaxy. Data products produced during this program will also be publically available to engage larger pulsar community

We propose to continue the PULSE@Parkes project in which high school students from Australia and around the World use the Parkes radio telescope in a remote observing model to observe and analyse pulsar data. The data from some PULSE@Parkes observations are used to support the space missions, other observations supplement the P456 Pulsar Timing Array project and the remainder were chosen in order to make a detailed analysis of pulsar timing irregularities and intermittency.

Long-term project observations for project P885 semester 2025APRS_06

We propose a modest program to continue monitoring 4 of the 6 known radio magnetars in order to achieve three primary science goals. The first is to characterise magnetar outbursts over long timescales, for which tracking their rotational, flux density, and polarisation properties provide a clear view of the impulse response of their magnetic fields. Second, understanding the links between magnetars the mysterious fast radio burst phenomenon through the discovery of rare emission and propagation effects, shared spectro-temporal phenomenology, and connections to high-energy (X-ray/gamma-ray) phenomena. Lastly, our continued monitoring has enormous benefit to the wider magnetar community, providing rapid alerts to changes in activity, adding context to unusual behaviour detected by high-enery observations, and a host of supplementary science through the teams extensive collaborative networks. The project and its precursors have been running since 2007 and have contributed to 21 publications since then. We are seeking to convert the project to long-term status, thereby also carrying these investigations into the SKA era.

We aim to carry out receiver pointing and characterisation tests of Parkes receivers. Typically, these tests are carried out after the receiver package is installed, but time does not always allow for proper characterisation. Receivers for consideration include UWL, MARS and 13MM packages. In addition to cross-referencing C007 for flux calibration via pointing, we aim to conduct gain-elevation and system temperature experiments using the Moon, to ensure users of the Parkes Observatory have the most accurate information available for calibration purposes.

Long-term project observations for project P456 semester 2025APRS_04

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. We are now in an exciting regime where a signal detected in our (and other data sets) has the form expected for a gravitational wave background. We, along with the international community, are now working hard to either confirm or deny this result, and to determine the astrophysical origin of this signal. With this proposal, we aim to maintain our pre-eminent position in the field. This is a continuing proposal for which observations of millisecond pulsars (MSPs) will continue to improve bounds on ultra-low-frequency gravitational waves until they are detected with confidence. 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, continued observations will resolve the background origin and individual sources will be identified; advancing the nascent field of gravitational wave astronomy.

Parkes observations for project P1364 semester 2025APRS_03

The propagation effects of the ionized interstellar medium (IISM) on pulsars are not well understood, and increase uncertainty on pulsar timing measurements. As high-precision pulsar timing is critical for using pulsars to detect phenomena as varied as gravitational waves and neutron star glitches, it is important to improve our understanding of these propagation effects. One such effect is chromatic dispersion, which contributes to timing noise but has been detected only once. We propose a set of 4 pointings with the Murriyang 64m Parkes Radio Telescope Ultra-Wide bandwidth Low frequency receiver (UWL), totaling 10 hours of telescope time. Our three targets are all strongly polarized pulsars in the Galactic plane, selected to maximize our chances of detecting one or both of the two types of chromatic dispersion. Non-detections will place upper limits on magnetic field strength and electron density in the IISM.

We propose a timing follow-up project for two newly discovered pulsars, J0915-6635 and J0917-6642, from the MWA-SMART survey. These pulsars were recently discovered from a blind periodic search of an 80-min SMART survey observation, with an localisation precision of 4 arcminutes. Initial flux density estimates suggest they are faint, requiring follow-up with the Parkes UWL receiver for precise timing solutions, flux density measurements, and polarimetric analysis. Initial analysis suggests a flux density 0.2-0.5 mJy for J0915-6635, and 0.1-0.3 mJy for J0917-6642  at 1.4 GHz, assuming a spectral index of -1.6. Observations with the Murriyang's UWL receiver will help enable a faster convergence to the full coherent timing solution and determine their spin and astrometric parameters, as well as further investigate this through measurements of pulsar flux densities and spectral indices. We will also perform a polarimetric analysis across a wide frequency range to better constrain the pulsars' geometries and emission properties.

Parkes observations for project P1363 semester 2025APRS_07

We propose to monitor the bursts from the hyperactive repeating fast radio burst FRB 20240619D over six months using the Murriyang UWL receiver. The primary aim is to study the evolution of burst activity and polarization properties with frequency and time, and to discover any potential periodicity in the burst activity. These insights will enhance our understanding of the progenitor, emission physics, and the immediate magneto-ionic environment of FRB 20240619D, thereby informing the general FRB population. A total of 15 hours of observing between August and November 2024 resulted in over 1300 bursts detected using the UWL receiver. Some bursts exhibit complex spectro-temporal emission patterns. The burst rate, based on Murriyang and MeerKAT observations, indicates that the source was active until September 2nd, after which it became inactive. Given that two other repeating FRBs have exhibited periodic activity cycles, it is reasonable to expect that FRB 20240619D could become active again, making continued monitoring crucial. The UWL receiver's broad frequency coverage and sensitivity are essential for detecting many bursts and enabling simultaneous observations at different frequencies. This is important for understanding the burst activity evolution with time and frequency, spectral properties, and underlying emission mechanisms. The combination of sensitivity and wide bandwidth makes Murriyang the ideal telescope for monitoring this FRB. Results from these observations will be pivotal in understanding FRB 20240619D's place within the broader repeater population and its potential connection to broader FRB progenitor models.

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 PX501) 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, relating to this proposal, 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 will be scheduled in shorter blocks and the data archived with a 10 year embargo.

Parkes observations for project P997 semester 2018OCTS

Ever since its detection in 1937 by Swings &amp; Rosenfeld, the methylidyne radical- CH, observed in diffuse clouds, has played an important role in studying the thermal, dynamical and chemical evolution these regions. In recent years the 532/536 GHz transitions of CH observed using HIFI on board Herschel has been established as an important tracer for H2 in diffuse and translucent clouds, which has led to a significant increase in its observations. The three ground state hyperfine structure (hfs) transitions of CH, observable in the radio range near 3.3 GHz although easily detected have weak intensities and non-LTE excitation and almost always appear in emission, even towards strong continuum sources. We would like to investigate the anomalous excitation of these lines utilizing the high sensitivity and spectral resolution provided by the new UWL receiver of the Parkes telescope, with the aim of (re-)establishing the 3.3 GHz lines of CH as a highly powerful probe of H2 in the Milky Way. In addition we would also like to observe the first rotational excited lines of CH at 0.7 GHz which due to Zeeman splitting will act as a useful potential magnetic probe. We would not only like to address the excitation conditions and enhanced emission at 3264 MHz but also constrain the physical conditions of the surrounding regions through non-LTE radiative transfer models utilizing collisional rate coefficients calculated by Paul Dagdigan, for which the Parkes observations will deliver strong constraints.

This dataset is the current total holdings of all Orthoptera - Rhaphidophoridae primary type specimens held at the Australian National Insect Collection.
ANIC is the World’s largest repository of Australian type specimens, currently holding about 19,000 primary types, which are the basis of every species description and the ultimate reference for species identification. Primary types are globally recognised as being the most valuable specimens of any collection, because they form the scientific basis of taxonomy, ensure stability of species names and are irreplaceable.
Digitising the irreplaceable primary type specimens will not only greatly benefit their curation and long-term safety but will also leverage biodiversity research outcomes of in-house and overseas researchers and facilitate reliable identification of native species and biosecurity threats.

LBA observations for project V629 semester 2023OCTS

The Evolutionary Map of the Universe (EMU) survey is currently underway using the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. This survey will catalogue up to 40 million sources, including high-z starbursts, normal star-forming galaxies, and active galactic nuclei (AGN). ASKAP has excellent surface brightness sensitivity, but its resolution limits its ability to investigate small-scale structures within sources, where much of the underlying physics can be revealed. 
We propose the EMU-VLBI pilot survey, a preparatory 48hr study of some high-interest targets that will allow us to prepare, scientifically and technically, for a future large programme that will eventually target thousands of high-value EMU sources. 
For this pilot survey, we will target eight high-value galaxy clusters. High-resolution observations will allow us to understand how jets in central cluster galaxies could suppress star formation, while other radio sources in the cluster could allow us to infer new insights into AGN triggering and the radio-galaxy life cycle. 
This survey is unique and will use the wide-field VLBI technique to target all sources within the primary beam, enhancing the legacy value of this proposal. This will allow us to cover further scientific aspects that include AGN identification, AGN-star-formation feedback, the role of radio emission in radio-quiet AGN, and the identification of other rare objects such as binary supermassive black holes and gravitational lenses.
