Data and Scripts for Tulloch et al (2025) - Airborne eDNA signal persistence

This dataset accompanies the study "Persistence of simulated airborne eDNA across capture materials and environmental conditions". The experiment assessed how environmental conditions (temperature, light exposure) and collection substrates influence the persistence and detectability of airborne environmental DNA (eDNA). Over a 180-day controlled laboratory trial, pork meat meal was used as a vertebrate DNA proxy, applied to a range of dry and liquid substrates. Samples were incubated under ambient (23 °C) and elevated (40 °C) temperatures with three light exposure levels.
Data types included:
Raw qPCR data: Cp and Ct from triplicate amplifications across all timepoints, materials, and environmental treatments.
Inhibition data: Percent signal reduction from inhibition tests across substrate types.
Environmental data: Continuous temperature and humidity readings from incubators, and periodic UV irradiance measurements.
R script: Annotated analysis script used to model DNA degradation, perform statistical tests, generate plots, and prepare publication figures.

Parkes observations for project PX500 semester 2025APRS_23

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 P1362 semester 2025APRS_03

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 to observe it with Parkes UWL every two months to track the profile evolution in this pulsar, and to derive times of arrival for an eventual detection of the affected Post-Keplerian parameters. 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.

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.

Long-term project observations for project P1041 semester 2025APRS_04

Omega Cen is the largest globular cluster in the Milky Way. I contains at least 18 known MPSs, and there are solid hints for the presence of an even larger pulsar population. We propose a regular monthly follow-up to refine the timing solutions of the five Parkes discoveries from 2020, and to find timing solutions for the 13 MeerKAT discoveries from 2023, in combination with six MeerKAT observations between 2021 and 2023, and future MeerKAt observations. These timing solutions should enable the detection of derivatives of the spin periods of these puslars, allowing us to probe the dynamics of Omega Cen and the the presence of a possible IMBH at its centre. Timing solutions will also enable the search for X-ray and gamma-ray pulsations in the multiple sources detected in this cluster. This study will allow us to better understand the populations of this globular cluster and its formation history. We request observations until 2030, when we expect to have measurements of the second period derivative of the five brighter discoveries, and first period derivative measurements for the later discoveries. These observations will also contribute to the study of eclipsing binaries, and may include future discoveries from pending searches in MeerKAT data.

Long-term project observations for project P456 semester 2025APRS_06

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 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.

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.

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.

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.

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

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.
