Pulsars are highly magnetised, fast spinning neutron stars. Their pulsations can be observed across an extremely wide electromagnetic window, from radio to high energy Gamma-ray. In this talk, I will briefly review observational properties of different populations of pulsars (e.g., young pulsars, magnetars and millisecond pulsars) and their emissions from radio to Gamma-ray. I will then focus...
The Cherenkov Telescope Array (CTA) is the next-generation observatory for ground-based gamma-ray astronomy. With more than 100 telescopes equipped with state-of-the-art technologies, it will provide a new view of the sky at energies from 20 GeV to 300 TeV at unprecedented sensitivity and angular resolution. Australia has a strong reputation in radio and optical astronomy and has made major...
More than a century after their discovery, the origin of cosmic rays is still a matter of debate. Gamma ray observations are one of the most powerful ways to test our ideas about cosmic ray origin. This is because gamma-ray photons are unavoidably produced in interactions between these energetic particles and interstellar matter. In this talk, I will briefly review the status of the field, and...
Very-high-energy (VHE) gamma-ray astroparticle physics is a relatively young field, and observations over the past decade have surprisingly revealed almost two hundred VHE emitters which appear to act as cosmic particle accelerators. These sources are an important component of the Universe, influencing the evolution of stars and galaxies. At the same time, they also act as a probe of physics...
