CTA's survey of blazars will require large-scale polarimetric follow-up, both on-demand and scheduled, using moderate-sized telescopes. The CTA-Oz consortium will prototype a new polarimeter that is optimised for this work, and commission it on local telescopes, leading to a full-scale plan for polarimetric follow-up infrastructure for CTA. I will sketch the landscape for CTA-Oz' polarimetry...
We will give an overview of the All-Sky Virtual Observatory (ASVO), including the services it provides and how it fits into the broader astronomical landscape. We will then focus on how the Data Central node of the ASVO can help CTA by providing fine-grained access control to data products, as well as supporting research teams to collaborate and spend more time on science. Finally we will look...
I report on the development of a Bayesian inference software pipeline to determine the sensitivity of CTA to dark matter annihilation events in the Galactic Centre. After highlighting the theoretical foundation of the pipeline I'll describe its components. I'll show predicted limits on the velocity-averaged annihilation cross section as the function of dark matter mass for one of the simplest...
ATCA in single-dish mode is able to map the HCO+ emission from ionised molecular gas. This not only traces ionisation, it can act as a finder chart for DCO+ observations to measure the cosmic-ray ionisation rate. I will present the state of our mapping of HCO+ towards the clouds around the W28 SNR, and outline future developments in molecular gas mapping.
The Fermi Bubbles are giant, γ-ray emitting lobes emanating from the nucleus of the Milky Way discovered in∼1-100 GeV data collected by the Large Area Telescope on board the Fermi Gamma-Ray Space Telescope. Previous work has revealed substructure within the Fermi Bubbles that has been interpreted as a signature of collimated outflows from the Galaxy’s super-massive black hole. I will show...
The extreme and often varying nature of Active Galactic Nuclei, along with gamma-ray bursts and other transients, can be investigated with observations of very-high-energy gamma rays. Studying them requires uninterupted availability and the capacity to take continuous observations over large spans of time. The Cherenkov Telescope Ring is thus an idea to establish a worldwide network of Imaging...
Peter Marinos aims to simulate the Galactic TeV diffuse gamma-ray emission with GALPROP for a variety of model parameters, and to make comparisons between these models and the diffuse emission estimated by the H.E.S.S. telescope array in their Galactic plane survey.
Kirsty Feijen aims to reveal the origin of HESS J1804−216 by modelling both the spectral and spatial gamma-ray morphology from...
During the next decade, the Vera C. Rubin Observatory will obtain high-resolution optical images of the Southern Sky at unprecedented depths. It will detect every night, millions of potential transient objects. I will introduce Fink, a broker developed on high-end technology and designed for fast and efficient analysis of Rubin big data. Fink will receive and process all transients detected by...
