With funding now available, we are starting the project to construct, deploy and operate the prototype polarimeter for CTA MWL observations. I will update the meeting on progress and plans.
I report on our work published in arXiv:2112.10371.
The design and detector prototype tests of the detectors for the Southern Wide-field Gamma-ray Observatory are underway. The University of Adelaide is contributing with the design and construction of the water Cherenkov tanks and the geo-membranes that will go inside the tanks.
The nature of the most extreme astronomical phenomena is better understood through observing their GeV and TeV gamma-ray flux, preferably by quickly following up on any transient events and continuously monitoring source flux variation. An Imaging Air Cherenkov Telescope (IACT) site in Australia, as part of a worldwide network of IACTs, would be a crucial part in achieving 24-hour all-sky...
To search for PeVatrons we need to make the absolute most of our highest energy event observations, but they are often at significant distances away from the detector array, potentially only triggering a single telescope, and the images may appear "truncated" or cut off in the telescope camera. Applying the pixel peak-time information is one way to try and recover these events, which may...
Short review of Milky Way PeVatrons in the latest surveys from the new-age radio telescopes. Cross-referencing these images with surveys in other frequencies, we are looking for previously not-detected SNRs.
SNR RXJ1713.7-3946 is one of the brightest young supernova remnants detected in the HESS Galactic Plane Survey. We have studied the C[II] emission towards the remnant and will provide an update on our analysis.
I report about my investigation of the optical “outflow” towards the Scutum supershell using multi-wavelength observations of HI, CO, X-rays, gamma rays and optical Halpha. This also includes studying the possible origin scenario for such an extended outburst.
HESS J1825-137 is one of the most powerful and luminous TeV gamma-ray pulsar wind nebulae (PWN). This makes HESS J1825-137 an excellent laboratory to study particle transportation in and around the powering pulsar. We have modelled the diffusive and advective transport of electrons from the powering pulsar, PSR 1826-1334. The resulting X-ray and gamma-ray emission was predicted through...
HESS J1804-216 is one of the brightest yet most mysterious TeV gamma-ray sources discovered so far. Previous arcminute-scale investigations of the interstellar medium (ISM) surrounding this source revealed that HESS J1804-216 is likely powered by a middle-aged supernova remnant (SNR) or pulsar. SNRs are believed to accelerate cosmic-ray protons at their shock front. These cosmic rays interact...
