I will share my experience from the first CTAO School and give a brief overview of the EMU discovery of a new high-latitude Galactic supernova remnant, G289.6+5.8, coinciding with a young X-ray binary.

Current-generation radio surveys, such as the EMU survey with ASKAP, are revealing an increasing number of low-surface brightness radio SNRs at high Galactic latitudes, such as the newly discovered Ancora supernova remnant (SNR) was recently detected with ASKAP at (l, b) = (288.8, -6.3) by Filipovic et al. 2023. Analysing 15 years of Fermi-LAT data, we detect spatially extended γ-ray emission...

I will provide an update on the Square Kilometre Array Observatory (SKAO), the fundamental science drivers together with their synergies with high-energy astronomy, and the expected design and scope of the project. I will also provide an update specifically on the progress of the growing SKAO entity in Australia and South Africa, including the Science and Engineering Operations Centres, and...

I will provide an overview about some current research I am conducting, which is analysing a potentially interacting pair of galaxies, NGC 5078 and IC4222, to investigate the potential impact of an AGN jet impacting a nearby galaxy. The radio jet of the AGN NGC 5078 appears to be oriented towards the smaller IC4222 and there is some evidence of physical interaction. Some preliminary SED...

There is an observed discrepancy of nearly 700 sources between theory and observation for the supernova remnants (SNRs) population in the Galactic plane. Their mean radio spectral index of −0.5 makes these objects brighter at low frequencies. The Murchison Widefield Array, a low-frequency radio interferometer, is a useful resource in detecting radio emissions from SNRs thanks to the wide field...

I will present an update of the CTA prospects for dark matter detection based on galactic centre observations, using dark matter effective field theory and simplified models as theoretical templates.

The nature of dark matter is now ubiquitous as one of the greatest puzzles to modern physics. Various efforts exist to narrow down its nature, including indirect direct detection experiments. These experiments presume dark matter particles annihilate, decay or through other means produce standard model particles that we can observe and relate back to the dark matter physics involved. One such...

An excess of gamma rays has long been observed by the Fermi-LAT experiment in the galactic centre in the GeV range. Although it is consistent with dark matter annihilation, it has been shown that it could also be due to an unresolved population of Millisecond Pulsars (MSPs). I will present an analysis that investigates under what conditions the Cherenkov Telescope Array could resolve TeV...

Optical polarimetry is an identified area in which Australia can contribute to CTAO. We are planning to construct a prototype polarimeter to be installed on one or more Australian optical telescopes.
Over the last few months, we've been able to look at our test data to check for sensitivity to polarisation signals. We find that one spot is brighter than the other, and this seems to be consistent.

AAL provides ongoing funding and administrative support for the Australian engagement with the CTAO. We also look after several other international engagements. This update will describe how all the AAL projects fit together and the prospects for deepening the relationship with CTAO.

The Scutum Supershell’s blowout includes spine and bow shock components, which are studied to investigate their physical and ionization properties. Previous studies have revealed optical from Hα, [S II], radio continuum PMN, and IR emissions in the right bow shock, characterised by high intensities in Hα and [S II] but lacking clear overlaps with known shock excitation sources. Spectroscopy...

We use the GALPROP cosmic ray (CR) framework to model the Galactic CR distributions and associated non-thermal diffuse emissions up to PeV energies. We consider ensembles of discrete, finite lifetime CR sources, e.g.~supernova remnants (SNRs), for a range of creation rates and lifetimes. We find that global properties of the CR sources are likely not directly recoverable from the current...

The Square Kilometre Array Observatory (SKAO) Science Operations Team is focused on the development and implementation of various workflows and procedures to ensure that SKA-Low and SKA-Mid will be operationally ready for transformational science. In this talk, I will give an overview of who we are and our current key objectives. I will discuss progress for envisioning a ‘year in the life’ of...

We present a new radio detection associated with the reflection nebula VdB-80 (nicknamed Lagotis). Reflection nebulae are typically associated with reflection of starlight off gas and dust in the optical range, making the detection of radio emission unique and interesting. This radio-continuum emission was discovered in the ASKAP EMU survey. The reflection nebula is situated in the...
