LBA observations for project V252 semester 2019OCTS

The TANAMI VLBI monitoring program has not only consistently met its stated objectives but evolved to incorporate new opportunities as they arise. As a result, in addition to anchoring numerous studies of AGN jets in the southern sky, TANAMI is a central player in the exciting emerging world of multimessenger astrophysics. Here we propose a continuation of this spectacularly successful program in a manner that will prepare us to exploit the emerging opportunity provided by TeV observations with the Cherenkov Telescope Array in combination with ongoing GeV observations by Fermi/LAT. VLBI observations will be vital as the only window to parsec scale kinematics and morphology of AGN providing jet parameters and structural change information essential to understanding the energetics of AGN jets.

LBA observations for project V447 semester 2019APRS

While there are an estimated 100 million black holes in our Galaxy, there are relatively few observational constraints on the mechanisms by which such exotic objects form. Theoretical work suggests that the most massive black holes should form via direct collapse, whereas those less massive should undergo a natal supernova. During a supernova, different magnitude velocity kicks can be imparted to the black hole, depending on the nature of the supernova. We propose to continue our successful program of high angular resolution LBA observations (triggered by our joint ATCA proposal) to test these predictions by measuring the proper motion of a black hole X-ray binary, which, when combined with the optically-determined systemic radial velocity and source distance, will provide the full three-dimensional space velocity of the system. Comparison with the predicted velocity from Galactic rotation will determine whether the system received a natal kick during a supernova, and hence place observational constraints on the formation mechanism of black holes. Natal kick distributions are a key parameter in simulating the expected rates of black hole mergers, which give rise to gravitational waves. With only a handful of BH proper motions having been measured to date, the sample size must be increased if we are to test the theoretical predictions for BH formation. We therefore request up to 24 hours of time with the LBA over the next year to perform high-precision astrometric observations during the hard states of the outburst of a black hole X-ray binary.

LBA observations for project V558 semester 2019APRS

PSR J0437–4715 is the nearest, brightest, and inarguably best-studied radio millisecond pulsar. Its radio pulses can be timed exceedingly accurately, making it one of the key objects in searching for low-frequency gravitational waves. The latest timing astrometry has provided a kinematic distance of 156.79+/–0.25 pc, which is five times more accurate than the existing VLBI distance and makes PSR J0437–4715 become the only known pulsar with a distance error &lt;1 pc. To verify the kinematic distance independently and provide a stringent constraint on the time stability of the Newton's gravitational constant G by high-precision VLBI phase-referencing astrometry, we have performed 12-hour (two epochs) in-beam phase-referencing observations of the pulsar and two nearby (&lt;1 arcmin) in-beam calibrators with the LBA+T6Km at 6.6 GHz. According to our preliminary data analysis, we have achieved a positional precision of ~25 microarcsec in the 2nd epoch. In this proposal, we request 19.5 hours (3 epochs, 6.5 hour per epoch, within about 1 year) observations of PSR J0437–4715 field with the same experiment setup. With five epochs total, we expect to measure the VLBI parallax with an accuracy of ~10 microarcsec. This would lead to a distance measurement as accurate as the kinematic distance measurement and a nearly one order of magnitude tighter constraint on the time variability of the gravitational constant G.

Tasmanian Orange Roughy Stereo Image Machine Learning Dataset

The Tasmanian Orange Roughy Stereo Image Machine Learning Dataset is a collection of annotated stereo image pairs collected by a net-attached Acoustic and Optical System (AOS) during orange roughy (Hoplostethus atlanticus) biomass surveys off the northeast coast of Tasmania, Australia in July 2019. The dataset consists of expertly annotated imagery from six AOS deployments (OP12, OP16, OP20, OP23, OP24, and OP32), representing a variety of conditions including different fish densities, benthic substrates, and altitudes above the seafloor. Each image was manually annotated with bounding boxes identifying orange roughy and other marine species. For all annotated images, paired stereo images from the opposite camera have been included where available to enable stereo vision analysis. This dataset was specifically developed to investigate the effectiveness of machine learning-based object detection techniques for automating fish detection under variable real-world conditions, providing valuable resources for advancing automated image processing in fisheries science.

Python workflow for seamlessly merging high resolution digital elevation models

This set of python scripts and Jupyter notebooks constitutes a workflow for seamlessly merging multiple digital elevation models (DEMs) to produce a hydrologically robust high-resolution DEM for large river basins.
The DEM merging method is adapted from Gallant, J.C. (2019) Merging lidar with coarser DEMs for hydrodynamic modelling over large areas, in: El Sawah, S. (Ed.) MODSIM2019, 23rd International Congress on Modelling and Simulation. Presented at the 23rd International Congress on Modelling and Simulation (MODSIM2019), Modelling and Simulation Society of Australia and New Zealand. https://mssanz.org.au/modsim2019/K24/gallant.pdf
The workflow runs on the CSIRO EASI platform https://research.csiro.au/easi/ and expects data stored in an AWS s3 bucket. Dask is used for parallel processing.
The workflow was built to merge all the available high-resolution DEMs for the Murray Darling Basin, Australia, using 852 individual lidar and photogrammetry DEMs from the Geoscience Australia elevation data portal Elvis https://elevation.fsdf.org.au/ and the Forests and Buildings removed DEM (FABDEM; Hawker et al. 2022- https://doi.org/10.1088/1748-9326/ac4d4f), a bare-earth radar-derived, 1 arc-second resolution global elevation model. The seamless composite high-resolution Murray Darling Basin DEM datasets (5 m and 25 m resolutions) produced with this workflow can be downloaded here https://doi.org/10.25919/e1z5-mx88.
The workflow is divided into three parts: 1) Preprocessing, 2) DEM merging and 3) Postprocessing and validation. The Jupyter notebooks in the workflow are also provided in html format for initial access to the content, without needing a python kernel.

Parkes observations for project P1321 semester 2024APRS_01

We propose to search for temporal variations in HI absorption spectra seen against background pulsars to characterise Tiny Scale Atomic Structure (TSAS) in the Milky Way interstellar medium (ISM). We will re-observe seven previously studied bright pulsars at two observing epochs in this semester, resulting in minimum and maximum experimental baselines of 0.25 and 50 years. These observations will test predictions that there is a minimum size scale set by the thermal and turbulent properties of the ISM, below which TSAS is only sporadically seen, and will potentially provide the first direct measurements of pressures in "large" TSAS features of &gt; 1000 AU.  By using a new phase-resolved spectral line mode that we have recently implemented on Parkes, we will cut data rates and processing times by factors of ~1000. Following the success of this pilot project, we plan to expand to a long-term monitoring programme. Successful demonstration of our techniques will lay the groundwork for future programmes on the SKA.

Extent of cropping, horticulture and plantation forestry in inland northern Australia between 1999 and 2023

The project mapped irrigated and rainfed cropping, horticulture and plantation forestry for the years 1999 and 2023. This was done to be able to determine the change in agricultural land use between 1999 and 2023. The study area is basically all areas north of the Tropic of Capricorn (ToC) and west of the great divide. However, the whole of the Gascoyne, Western Australia has been included and the whole of the Northern Territory (NT) including areas south of the ToC. Off-shore Islands are not included except for the Tiwi Islands (NT). The project has produced two ESRI shapefile files that can be used in a geographic information system (GIS).

Parkes observations for project P595 semester 2025APRS_01

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_01

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.

Parkes observations for project P1328 semester 2025APRS_01

Fast radio bursts are peculiar micro-millisecond duration transients, which have been seen to be extragalactic in origin. Since their discovery, a dichotomy has emerged in their population. Some FRBs have been seen to be repeating, while others have not been seen to be repeating. The repeating FRBs, such as FRB 20180301A, 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. Additionally, FRB 20180301A has been seen to have interesting polarisation properties, such as a switch in the sign of RM, indicating a reversal in the magnetic field and a marked reduction in the linear polarisation fraction towards lower frequencies (depolarisation). The previous Parkes/Murriyang source follow-up has also revealed a temporal evolution in the dispersion measure (DM) of the source and tentative evidence for correlation in the DM and rotation measure (RM). The ultra-wideband low (UWL) receiver on Parkes/Murriyang is ideally suited to explore the wideband spectro-temporal and polarimetric behaviour of the source. We propose regular monitoring of FRB 20180301A using UWL to model the magnetic field evolution, study its circumburst media using depolarisation behaviour, and constrain any correlation of DM and RM.
