I will present a brief status report on CTAO.
I will give an update on recent SKAO activities since the last CTAO | Australia meeting in late 2024.
Gamma-ray emission from stellar activity, usually generated from relativistic particles, plays an important role in the space weather and habitability of exoplanets. Young dwarf stars of K-type and later are far more magnetically active than the Sun, yet only one other isolated main sequence star (TVLM 513-46546) apart from the Sun is detected in gamma-rays. Stacking surveys of radio, optical...
I will discuss modelling work we are embarked on that considers injection, transport, energy loss, and radiation of cosmic rays in the low density plasma trapped in dark matter halos surrounding galaxies, galaxy groups, and galaxy clusters. I will show that we can neither blithely ignore the hadronic gamma-ray emission from these particles nor their potential gas dynamical implications. The...
Astronomical and Cosmological data irrefutably point towards an invisible matter component of the universe 5 times denser than the visible matter. The masses of particle physics dark matter masses can span over 30 orders of magnitude. On the heavy dark matter mass, high energy gamma ray telescopes provide an unique opportunity to probe the parameter space of well-motivated models. I will...
The Small Sized Telescopes (SST) of the Cherenkov Telescope Array Observatory are one of three designs to be used in the array, specifically focused on observing TeV gamma-rays. A partial prototype of the final camera design for these telescopes (QCAMi) has been built, and will undergo on-sky testing in Tenerife this June/July. As part of this commissioning process, waveform data is produced...
The Cherenkov Telescope Array Observatory (CTAO) is a next-generation gamma-ray observatory in both the Southern (Paranal, Chile) and Northern Hemisphere (La Palma, Spain) and will consist of up to 100 imaging atmospheric Cherenkov telescopes. With sensitivity far exceeding current facilities, CTAO will provide detailed measurements of gamma rays from GeV up to a few 100s of TeV. CTAO has a...

Quick updates on MoU arrangements for the Consortium
From ATCA project proposal C3145: "We are building on Australia’s rich tradition of spectral line legacy surveys to deliver a 7-mm dense gas survey of the Fourth Quadrant Galactic Plane in multiple molecular spectral lines and continuum emission. Using ATCA autocorrelation data, the "Full Strength" MALT45 will address a wide range of astrophysical challenges, including directly testing...
I will present the results of a new multi-frequency analysis of one of the largest supernova remnants in the nearby Large Magellanic Cloud. I will present the new high-resolution radio data available from the MeerKAT telescope to analyse the radio properties. The results show new filamentary structure which extend the size of J0450-7050 and a flat spectral index of -0.26.
