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...
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...
I will present an update on the status of CTA, an overview Australia's involvements in CTA, and future funding plans for Australia's contributions moving towards the operational phase of CTA.
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.
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 current capabilities and future prospects of the Australia Telescope Compact Array and Long Baseline Array will be presented.
