Performance of a small array of Imaging Air Cherenkov Telescopes sited in Australia

چکیده

As TeV gamma-ray astronomy progresses into the era of Cherenkov Telescope Array (CTA), there is a desire for capacity to instantaneously follow up on transient phenomena and continuously monitor flux at energies above $10^{12}$ eV. To this end, worldwide network Imaging Air Telescopes (IACTs) required provide triggers CTA observations complementary continuous monitoring. An IACT array sited in Australia would contribute significant coverage Southern Hemisphere sky. Here, we investigate suitability small how different design factors influence its performance. Monte Carlo simulations were produced based Small-Sized (SST) Medium-Sized (MST) designs from CTA. Angular resolution improved with larger baseline distances 277m between telescopes, energy thresholds lower 1000m altitude than 0m. The $\sim$300 GeV threshold MSTs proved more suitable observing transients $\sim$1.2 SSTs. four was estimated give 5.7$\sigma$ detection an RS Ophiuchi-like nova eruption 4-hour observation. We conclude that MST-class IACTs Australian site ideally complement capabilities

Optical SETI with Imaging Cherenkov Telescopes

The idea of searching for optical signals from extraterrestrial civilizations has become increasingly popular over the last five years, with dedicated projects at a number of observatories. The method relies on the detection of a brief (∼ few ns), intense light pulse with fast photon detectors. Ground-based gamma-ray telescopes such as the Whipple 10m, providing a large mirror area and equipped...

Observations of Pulsar Wind Nebulae with the VERITAS Array of Imaging Atmo- spheric Cherenkov Telescopes

Many of the recently discovered galactic very high-energy (VHE) γ-ray sources are associated with Pulsar Wind Nebulae, which is the most populous Galactic source category at TeV energies. The extended synchrotron nebulae of these objects observed in the X-ray band are a hallmark of the relativistic winds, generated by the young, energetic neutron stars, that interact with the matter ejected by ...

Triggering of Imaging Air Cherenkov Telescopes : PMT trigger rates due to night - sky photons

Imaging air Cherenkov telescopes are usually triggered on a coincidence of two or sometimes more pixels, with discriminator thresholds in excess of 20 photoelectrons applied for each pixel. These thresholds required to suppress night-sky background are significantly higher than expected on the basis of a Poisson distribution in the number of night-sky photoelectrons generated during the charact...
