Parkes observations for project PX500 semester 2025APRS_29

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 P512 semester 2006APRS_01

We propose to undertake a pulsar survey along the Galactic Plane using the new Methanol Multibeam receiver in order to uncover pulsars previously selected against in lower frequency surveys. The scientific aims of this survey are
(a) to discover young pulsars in the spiral arms, hidden at lower frequencies, (b) to improve our knowledge of the distribution of dispersing and scattering material, particularly in the inner Galaxy, (c) strike it lucky and discover unique objects (e.g. a pulsar with a black hole companion and short period binary pulsars) and
(d) to survey the transient radio sky at high frequencies. Simulations have shown that we expect to find a total of 200 pulsars of which about one half will be new detections.

Parkes observations for project P1211 semester 2024APRS_22

Traditional pulsar searching techniques are not sensitive enough to extreme pulsars such as millisecond pulsars (MSPs) in compact binaries (e.g., Pulsar-Blackhole binary systems), extremely fast spinning pulsars (e.g., sub-MSPs), and high dispersion measure (DM) pulsars. Such a situation is now changed thanks to the development of next generation radio telescope arrays such as Australian Square Kilometer Array Pathfinder (ASKAP). ASKAP is capable of conducting highly sensitive radio continuum surveys with wide sky coverage (e.g, Evolutionary Map of The Universe survey). One of the solutions is to find pulsar candidates in radio continuum surveys such as ASKAP surveys and then carry out targeted searches. This technique allows us to search over the wide bandwidth with full field of view while avoiding the need for expensive pixel-by-pixel high time resolution searches. In this proposal, we propose to observe 16 pulsar candidates identified in the Galactic plane using new ASKAP EMU images. We found 22 candidates by selecting sources with spectral index steeper than -2.0 and compactness less than 1.2. Among them 13 are known pulsars and a reasonable number of candidates to follow up (9 sources). In total, we have 16 candidates including seven sources from 2023APRS semester. Because of the dense ionised medium in the Galactic Plane, MSPs are likely to be missed by previous pulsar surveys carried out at 1.4 GHz. Here, we propose a targeted pulsar search with the Parkes UWL which allow us to search pulsation at higher frequencies and therefore avoid strong DM smearing and scattering effects.

Parkes observations for project P630 semester 2011APRS_09

We propose to carry out the most ambitious and comprehensive all-sky survey for pulsars and transient sources to date. Using the 20cm multibeam and a new digital filterbank array this survey will create a petabyte digital record of the sky that can be data mined in the future and used to search for relativistic binary and millisecond pulsars, RRATs, and extragalactic radio bursts. The survey should discover 100s of new millisecond and normal pulsars and help define the lower limit to pulsar periods, test theories of relativistic gravity, find transients and provide pulsars for gravitational wave detection.

Long-term project observations for project P1321 semester 2025APRS_14

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 P1357 semester 2025APRS_09

MeerKAT has already discovered a number of Galactic transients, which are most likely to be Rotating Radio Transients (RRATs). Previous observations of a few of these sources with the Parkes UWL receiver have proven its utility in follow-up timing observations of MeerKAT discoveries.
  MeerKAT has discovered a few more RRATs in its latest observing cycle and more good quality UWL observations of these sources are required to determine the rotational period and period derivative and also to facilitate the study of their emission properties. Therefore, we request follow-up observations of 5 new sources to achieve this and to further enable spectral and polarization studies of these sources. Given the potential link between RRATs, magnetars, and some fast radio bursts (FRBs) suggested by both observations and theories, this study could reveal more similarities between these different classes of transient sources and significantly advance our understanding of their origins.

Parkes observations for project P595 semester 2025APRS_24

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 P960 semester 2025APRS_10

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.

Spatial causal network for hydrogen production in the Pilbara region, Western Australia

This dataset was compiled by the Water for Sustainable Hydrogen project from source data referenced within the dataset and/or metadata. The spatial causal network comprises a rigorous and comprehensive scientific assessment of potential causal pathways by which hydrogen and renewable energy development can affect environmental assets. The network approach is coupled with a systematic evaluation of the likelihood, consequence and mitigation options for each causal pathway from one or more human activities to multiple valued assets. The method includes analysis of the confidence in these evaluations, recognizing where knowledge gaps constrain assessments of risks to particular assets. The causal network approach is complemented by a spatially explicit analysis of the region that allows residual risk (i.e. risk remaining after all feasible mitigations) to be mapped for all valued assets. This identifies which activities could lead to potential impacts of varying concern (rated from ‘very low’ to ‘very high’), their likely pathways, which valued assets are at risk and where these residual risks are greatest. The output maps reveal ‘risk hotspots’ where more detailed local-scale assessments and monitoring should focus. This dataset contains the spreadsheets describing the causal network for the region and the spatial grids evaluating likelihood, consequence and mitigation. The dataset also contains a spreadsheet summarising the results and all output grids with the level of concern.

Parkes observations for project P1054 semester 2025APRS_15

With this proposal we ask time to continue our timing follow-up campaign of pulsars discovered with the MeerKAT telescope. Fourtytwo sources have been discovered in targeted observations of Fermi unidentified point sources, two towards Supernova Remnants, 19 in the Magellanic Clouds, 105 in Globular Clusters and 81 in a survey of the Galactic plane. A large fraction of the new discoveries are recycled pulsars (including a few relativistic systems and several 'spider' binaries), or young pulsars. Timing observations have an essential role in exploiting the full potential of any pulsar discovery, allowing for the precise measurement of rotational, astrometric and orbital parameters which, in turn, give us powerful tools to improve our understanding of the physics in extreme environments as well as of the population of neutron stars as a whole. The UWL receiver of the Parkes telescope is a sensitive, versatile instrument that is allowing us to successfully time these new sources, in the bright-end of TRAPUM discoveries.

Drastic index map for the Pilbara region

This dataset represents the intrinsic aquifer vulnerability to contamination evaluated for unconfined aquifers in Fitzroy, based on the DRASTIC method (Aller et al. 1987). This semi-quantitative but spatially distributed method is especially suited for regional investigations with limited data availability. The DRASTIC index is calculated based on seven components: Depth to groundwater, net recharge, Aquifer media, soil media, topography (slope), impact of vadose zone and hydraulic conductivity of the aquifer (Aller et al. 1987). Areas with unconfined aquifers or with shallow water tables receive a high index and, vice versa, area with fractured rock aquifers and deep water tables have a low index.

For the Pilbara region, based on the spatial distribution of index values, unconfined aquifer contamination due to a spill at the surface is considered not possible if the drastic index is less than 100. In grid cells with DRASTIC index between 100 and 125, unconfined aquifer contamination due to spill at the surface is considered possible but not material. In areas with DRASTIC indices above 125, unconfined aquifer contamination due to a spill at surface is considered material, so avoidance and mitigation strategies are considered.

Further information about the DRASTIC map and the development of this map is described in Holland et al. (2024) [Securing water for an emerging Australian hydrogen industry - Methods report].

Parkes observations for project P1338 semester 2025APRS_48

Fast radio bursts (FRBs) are millisecond-duration radio bursts of extragalactic origin. Since the discovery of the first FRB in the archival Parkes/Murriyang multibeam data, a broad dichotomy in population has emerged. Some FRBs have been seen to be repeating, while others are not, despite a significant amount of follow-up using different radio telescopes. The repeating FRB 20240114A was recently discovered by CHIME/FRB, which has been seen to have an exceptionally high burst activity. Such extreme burst activity has not been seen in any other source. The repeating FRBs, such as FRB 20240114A, provide an unparalleled window into their circumburst environment due to their repeating nature, which can be used to constrain possible progenitor models and test underlying emission mechanisms. The previous Parkes/Murriyang source follow-up has also revealed intriguing spectro-polarimetric properties, such as frequency-dependent evolution of burst central frequency or chromaticity, a possible activity window, significantly large circular polarisation (CP), and frequency-dependent CP. These properties hold the key towards understanding the circumburst environment of the FRBs, and test possible progenitor models. A large bandwidth instrument with reliable polarimetry has been critical in uncovering these properties. The ultra-wideband low (UWL) receiver on Parkes/Murriyang is ideally suited to explore the source's wideband spectro-temporal and polarimetric behaviour. We propose a campaign to regularly follow up FRB 20240114A to ascertain its long-term evolution of spectro-temporal properties.

Parkes observations for project P1183 semester 2025APRS_13

After nearly two years of monitoring, comprising 126.7 hours over 57 observations with the Parkes telescope and 49.4 hours across 101 observations with the FAST telescopes, we have determined that FRB 20220529 is an extremely active repeater. It exhibits one of the longest activity durations and a potential period. Due to frequent observations scheduled with both Parkes and FAST, we recently observed an abrupt rotation measure (RM) flare in this source. This is the first detection of such an <code>RM flare'' in a fast radio burst (FRB), suggesting that the source is in an environment with occasionally erupting coronal mass ejection. This presents a unique opportunity to study the eruption environment of FRBs and investigate the relation between burst activity and other burst parameters. If confirmed, the periodicity and the</code>RM flare'' of FRB 20220529 would corroborate each other and become a ``smoking gun'' of the binary origin of FRB. In our previous analysis, both Parkes and FAST observations have proven essential. While FAST's higher sensitivity has enabled the capture of many bursts, Parkes' wideband receiver has provided a good burst detection rate even during low-rate phases. Notably, during the RM flare, two high signal-to-noise ratio bursts from Parkes have been crucial in understanding the RM variations. To further investigate FRB 20220529, we have scheduled regular FAST observations every fortnight, monitoring the source for 20 minutes each time. Therefore, we also propose to monitor FRB 20220529 using the Parkes UWL receiver, ensuring high-time resolution and employing full-polarization observations.

Parkes observations for project PX600 semester 2020APRS_126

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
