Parkes observations for project P1219 semester 2025APRS_02

Magnetic fields are fundamental in regulating star formation and the evolution of molecular clouds. Zeeman splitting offers a unique method to directly measure line-of-sight magnetic field strengths in interstellar environments, from the diffuse ISM to dense cores. Observations of HI and OH absorption toward pulsars provide an unprecedented opportunity to measure magnetic fields with high precision, benefiting from pulsars' small angular sizes and reliable Stokes V spectra unaffected by instrumental effects. Our recent tentative Zeeman splitting detections in OH absorption toward PSR J1644-4559 with Parkes reveal magnetic field strengths that suggest magnetically subcritical states, where magnetic pressure counteracts gravity. This challenges conventional theories of subcritical cold neutral medium (CNM) transitioning to supercritical star-forming molecular clouds, emphasizing the need for detailed investigation. We propose a continuation of Zeeman splitting studies through high-sensitivity OH and HI absorption observations of pulsars PSR J1644-4559, J1721-3532, and J1852+0031 using Parkes. By employing an innovative phase-resolved spectral technique and extending integration times, we aim to enhance Zeeman detection sensitivity and study magnetic field transitions in the CNM and quiescent molecular clouds. This work will refine our understanding of subcritical-to-supercritical transitions in star formation, establish pulsar absorption as a robust probe of interstellar magnetic fields, and advance observational techniques critical to star formation studies.

Parkes observations for project P1171 semester 2025APRS_02

The origin of Fast Radio Bursts (FRBs) is still unclear with a plethora of theoretical models for their origin.
  Several models predict associated multi-wavelength emission, but previous searches for optical, X-ray or
  gamma-ray counterparts of FRBs have not led to any detection. The Galactic magnetar SGR 1935+2154A has
  been observed to simultaneously emit FRB-like bursts and X-ray flares, which suggests that also extragalactic
  FRB sources may exhibit X-ray counterparts. Because of the high cost of X-ray satellites and in face of the
  relatively low FRB detection probability in their small field of view, coordinated radio and X-ray observations are
  logistically very difficult to set up. We propose a new approach using the X-ray satellite XMM-Newton and the
  Parkes/Murriyang radio telescope to put constraints on the theoretical models: We aim to conduct shadowing
  observations with the Parkes telescope to search for new FRBs in fields that are simultaneously covered by
  XMM-Newton. We hereby target regular XMM observations of nearby (low-z) galaxies, to increase our
  detection chances of possibly associated X-ray emission. In case of an FRB detection in the radio band, we will
  have guaranteed simultaneous X-ray coverage and will get detailed information about the associated X-ray
  spectrum and light curve since all XMM-Newton data will become public a year after the observation.

Parkes observations for project PX500 semester 2025APRS_11

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 P1338 semester 2025APRS_17

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.

A common standard template for representing stable isotope results and associated metadata

This dataset contains a common standard template for representing the metadata of stable isotope results environmental samples (e.g., soils, rocks, water, gases) and a CSIRO-specific vocabulary for use across CSIRO research activities. The templates includes core properties of stable isotope results, analytical methods, and uncertainty of analyses, as well as associated metadata such as such as their name, identifier, type, and location. The templates enables users with disparate data to find common ground regardless of differences within the data itself i.e. sample types, collections.
The standardized templates can prevent duplicate sample metadata entry and lower metadata redundancy, thereby improving the stable isotope data curation and discovery. They have been developed iteratively, revised, and improved based on feedback from researchers and lab technicians.
Use of this template and vocabularies will facilitate interoperable and machine-readable platform-ready data collections.

ASKAP Data Products for Project AS321 (ASKAP monitoring of three long-period radio transients): images and visibilities

The long-period radio transients are an emerging class of unusual astrophysical phenomena that generate bursts of radio waves at slow periodicities (minutes to hours). Their nature is mysterious and very little data exists toward the ~ten that are known (10-20 pulses is typical). As novel and rare transients, most radio observations carried out so far have consisted of Directors' Discretionary Time and Target-of-Opportunity requests. Consistent monitoring campaigns are challenging, as the sources only generate radio waves infrequently, making long dwells inefficient. Here we propose leveraging ASKAP's wide field-of-view to target three long-period radio transients in a single pointing, obtaining over 150 pulse measurements with 25 hours of observing time, in full polarisation, using CRACO and the correlator together to probe timescales of 100ms to tens of minutes. This will be a treasure trove for understanding the nature of these sources and will be the first consistent monitoring campaign at these frequencies.

Application-ready quantile-delta-change (QDC) scaled CMIP6 climate projections for Australia (time-slices, 5km grid)

This collection consists of application-ready climate projections based on observations, adjusted through a quantile-delta-change method to incorporate projected climate changes from CMIP6 Global Climate Models.
The collection consists of daily projections of precipitation, mean downwelling shortwave radiation, maximum and minimum near-surface temperature, maximum, mean and minimum near-surface relative humidity, and mean near-surface wind speed for 9 CMIP6 models. Two 30-year windows of projections are available (2035-2064 and 2070-2099) for four shared socio-economic pathways (SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5). Data is available with two sources of historic climate observations for Australia: AGCD (for precipitation and temperature only) and BARRA-R2. The BARRA-R2 baseline data has been interpolated to the same resolution as AGCD (~5km).
In addition, historical baseline data for 1985-2014 from AGCD and BARRA-R2 used for the quantile-delta-change adjustment are also available in the collection.

Long-term project observations for project P574 semester 2025APRS_01

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.

Long-term project observations for project P1361 semester 2025APRS_01

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 P1327 semester 2025APRS_05

The radio radiation neutron star includes objects with spin periods ranging from milliseconds to tens of seconds. In the past years, however, the discovery of ultra-long period radio transient sources has posed a new challenge to the classical theoretical framework of the neutron star magnetospheric dipole model. In Parkes' observations, we detected single pulses with similar durations to fast radio bursts (FRBs), notably containing quasi-periodic substructures similar to some FRBs, and similar phenomena may have similar physical mechanisms. By observing its single-pulse structures and polarization profiles, we hope to understand the origin of radio emission from magnetars and establish the potential association between Galactic neutron stars and FRBs. Hence, we strongly request to keep monitoring this source, aiming to detect more signal pulses and interesting multi-structure pulses from PSR J0901-4046 to provide insights into magnetars as possible progenitor origins of FRBs, strengthening the link between magnetars and FRBs.

Parkes observations for project P1054 semester 2025APRS_03

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.

Parkes observations for project P1183 semester 2025APRS_04

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 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 theRM 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.

Long-term project observations for project P885 semester 2025APRS_03

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.
