Parkes observations for project PX600 semester 2020APRS_137

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

Parkes observations for project P595 semester 2025OCTS_08

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.

Parkes observations for project P1382 semester 2025OCTS_12

The prevalence of millisecond pulsars (MSPs) in and around the Galactic center and the bulge has been one of the key questions in pulsar astronomy. In addition to finding more exotic and interesting binary systems at and around the Galactic center and bulge due to the enhanced density of stars/stellar remnants, MSPs are also proposed to be one of the candidates to explain the observed Fermi gamma-ray excess. However, most of the MSPs discovered so far are field (disk) MSPs or those in globular clusters. Initial steps towards addressing the question of Galactic center/bulge MSPs were made with the discovery of the first MSPs in a Galactic filament, but more progress comes from the discovery of a sample of MSPs around the Galactic center. Blind surveys targeting MSPs can suffer from many observational biases that smear the pulses due to binary acceleration, scattering from the enhanced density, and so on, which increases the parameter space for discovery and can sometimes make the problem intractable. However, if pulsar candidates can be identified reliably from imaging surveys, then targeted observations can make the problem tractable in identifying the pulsations. We followed up a sample of polarized sources identified in the MeerKAT bulge imaging survey and discovered a sample of 16 new MSPs. Here we request the timing observations of 8 interesting MSPs (a subset of our discovery sample), to study the binary nature of these sources and their potential inclusion in pulsar timing array efforts.

Young and energetic pulsars can power pulsar wind nebulae (PWNe), which are observable across the electromagnetic spectrum from radio to X-rays. Occasionally, the origin of a PWNe is connected to the parent supernova remnants (SNR). The exceptional sensitivity and high resolution of next-generation radio surveys conducted with ASKAP and MeerKAT make them particularly effective in discovering diffuse and low surface brightness objects in our Galaxy, such as PWNe and SNRs. We can then use these PWN and SNR associations to guide our targeted search for radio pulsars. This strategy has proven successful with our recent discoveries of two high-dispersion measure (DM) pulsars powering a bow-shocked PWNe. Building on this success, we continue our search and have selected the most promising and scientifically compelling candidates for detailed follow-up investigation. We propose to use the Parkes Ultra-Wideband Low (UWL) receiver to conduct a targeted search for three pulsar candidates. Given that the pulsar candidates are embedded in SNRs and/or PWNe, located near the Galactic Plane, and may be at large distances, we expect them to have high DMs. High DMs result in scattering and pulse broadening, making them difficult to detect in conventional low-frequency pulsar surveys. The wide frequency coverage of UWL, particularly its high-frequency band (3-4 GHz), presents a unique opportunity to mitigate these effects and significantly enhance the detectability of distant, highly dispersed pulsars.

Long-term project observations for project P1101 semester 2025OCTS_02

We propose a long-term project to monitor a very active repeater, FRB 20190520B, with Murriyang's UWL system. Our previous observations show that FRB 20190520B is not only among the most active FRBs that can be observed with Murriyang, but also shows extreme rotation measure (RM) and dispersion measure (DM) evolution, along with distinctive behavior at 3GHz frequency. This makes the UWL receiver uniquely suited for detailed studies and long-term monitoring of this repeating FRB. Through this program, we anticipate detecting a large sample of bursts from this FRB. In collaboration with FAST, we aim to investigate the time evolution of various properties of FRB 20190520B, enhance our understanding of polarisation across an extremely wide bandwidth with high sensitivity, and gain deeper insights into the local environment and emission mechanisms of FRBs.

Parkes observations for project P1362 semester 2025OCTS_02

PSR J1757-1854 is the most relativistic galactic double neutron star system. Its eccentricity makes it an ideal playground for gravity experiments with pulsar timing. Via observations of its profile evolution, we can constraint its rate of geodetic precession. Currently, there are four possible geometric configurations that explain the time evolution of the polarisation swing. The geodetic precession and the Lense-Thirring effect will eventually manifest themselves in the post-Keplerian parameters within the next decade, allowing for two further tests of gravity. We propose a single observation with a maximum integration of ~8 hours allowed by LST time for this semester. We will inspect the polarisation properties of this observation, and we will add the ToAs to a global timing campaign. These observations will be added to joint GBT and (past) MeerKAT observations, and they will be part of a long-term, global observational program of this pulsar.

Long-term project observations for project P1321 semester 2025OCTS_04

The atomic interstellar medium shows tiny-scale optical depth fluctuations on the scale of 0.1~10,000 AU, whose origin and nature are poorly understood. The existence of this Tiny-Scale Atomic Structure (TSAS) has significant implications, potentially calling into question our fundamental understanding of heating, cooling and dynamical processes in the interstellar medium. Yet observations remain sparse. This long-term project plans to search for temporal variations in HI absorption spectra seen against background pulsars to characterise TSAS in the Milky Way interstellar medium (ISM). These observations constitute the largest number of sightlines and densest temporal sampling ever performed in a single experiment, and will test predictions that TSAS is the tail end of a turbulent cascade, constrain its minimum size scale (down to resolutions of ~0.05 AU) and potentially provide the first direct measurements of pressures in "large" TSAS features of &gt; 1000 AU. We make use of the phase-resolved spectral line mode that we have recently implemented on Parkes, which has cut data rates and processing times by factors of ~1000 compared to past studies. This is an expansion of our pilot P1321 to a long term study.

Parkes observations for project P1378 semester 2025OCTS_02

We propose to observe 2XMM J104608.7-594306 with the Murriyang UWL receiver. This is a known thermally X-ray emitting neutron star in the Carina Nebula, which was recently discovered to show remarkable bursts of coherent radio emission. This is the first of this class of neutron stars to be seen to emit radio pulses. The primary goal of this proposal is to search for more coherent radio bursts from this object, and study their morphology, spectral features and polarization properties. These aims will provide us with crucial insights into the common emission mechanism operating over a wide range of magnetic field strengths and neutron star ages, which will help to understand the physical link between the different classes of neutron stars and their evolutionary pathways.

Parkes observations for project P1386 semester 2025OCTS_05

J0045-7319 is a B star/pulsar binary in the Small Magellanic Cloud (SMC) with an orbital period of 51 days. The system is highly eccentric, with a closest approach of only 6 B-star radii, and it offers an unusual probe into massive stars in the SMC. Although similar systems exhibit strong dispersion measure (DM) variation during periastron arising from the stellar wind, observations in 1996 on the Parkes 70 cm receiver found no evidence of a wind from the B star. We propose a new set of observations on the Ultra-Wide Low-frequency receiver (UWL) designed to measure the wind. A null result will decrease the known upper limit on the B-star wind's contribution to DM by a factor of 9.

Parkes observations for project P1380 semester 2025OCTS_07

The association of FRB 200428 with the Galactic magnetar SGR 1935+2154 confirms that magnetars can power fast radio bursts (FRBs). However, FRB 200428 is 4 to 8 orders of magnitude less energetic than the typical population of cosmological FRBs. This discrepancy is likely due to the moderate magnetic field strength and evolved age of SGR 1935+2154. In contrast, newborn extragalactic magnetars, such as those formed in gamma-ray burst (GRB) central engines, are expected to have much stronger magnetic fields, more rapid spin-down, and highly dynamic magnetospheres, all of which favor the production of brighter and more frequent FRBs.
We propose a targeted search for FRBs from the recently localized GRB 230307A, a long-duration GRB with evidence suggesting the formation of a young magnetar. Given the source's relatively close distance (291 Mpc) and possible youth (less than 3 years), it offers a compelling opportunity to test FRB generation mechanisms during the early evolution of a magnetar.
We request 30 hours of observing time with the Parkes 64-m Murriyang telescope using the ultra-wideband low-frequency (UWL) receiver. Our plan includes one 10-hour long-duration session to detect rare or clustered bursts, and ten 2-hour sessions spread over 2-3 months to sample temporal variability. Data will be processed with state-of-the-art pipelines for single-pulse searches and coherent dedispersion.
A detection would strongly support magnetar-origin FRB models and provide key constraints on the early-time activity of GRB-formed neutron stars.

Australia-wide 30 m machine learning-derived canopy height models composites: best pick and median

This dataset is part of the OzTreeMap project and provides two new 30 m spatial resolution canopy height products for continental Australia: (1) the best-pick canopy height model (pick-CHM); and (2) the median canopy height model (med-CHM). Both products were generated and validated as part of the study titled “Accuracy of Machine Learning-Derived Canopy Height Models at Continental Scale.”
The pick-CHM is a composite model in which each 30 m pixel adopts the most accurate canopy height value among four publicly available machine learning-derived CHMs—Tolan et al. (2024), Lang et al. (2023), Potapov et al. (2021), and Liao et al. (2020)—based on the vegetation class (Scarth et al., 2019) that the pixel represents and our vegetation-specific accuracy assessment (see lineage). The med-CHM represents a pixel-wise median composite of the same four CHMs and achieved the highest overall accuracy when validated against 22,967 km² of reference airborne point cloud data across 16 Australian vegetation classes.
Both datasets are provided as single-band GeoTIFF rasters in EPSG:3577 (Australian Albers) coordinate reference system, with 30 m spatial resolution and float32 data type. These CHMs offer improved accuracy and spatial consistency compared to the individual global products supporting continental-scale applications in forest structure monitoring, carbon accounting, and ecosystem assessment.

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.

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.

We recently discovered two new pulsars J1849+1001 (35.1 ms) and J1839+0543 (57.9 ms) in a FAST pulsar survey at intermediate Galactic latitudes (PT2020_0141). Follow-up timing observations show that they are in circular orbits with massive companions. This suggests that PSR J1849+1001 and J1839+0543 can be classified as the intermediate-mass binary pulsar (IMBP). Their massive companions also make them promising systems to measure "Post-Keplerian" parameters through pulsar timing. These Parkes observations will be combined with regular timing observations with FAST or MeerKAT to measure "Post-Keplerian" parameters and then measure both neutron star and companion masses.
