87. Cherenkov Telescope Array: The Next Generation Gamma-ray ObservatoryRene A. Ong, Christopher Eckner, Gašper Kukec Mezek, Samo Stanič, Serguei Vorobiov, Lili Yang, Gabrijela Zaharijas, Marko Zavrtanik, Danilo Zavrtanik, 2017, published scientific conference contribution Abstract: The Cherenkov Telescope Array (CTA) will be the next-generation gamma-ray observatory,
investigating gamma-ray and cosmic ray astrophysics at energies from 20 GeV to more than 300 TeV. The observatory, consisting of large arrays of imaging atmospheric Cherenkov telescopes in both the southern and northern hemispheres, will provide full-sky coverage and will achieve a sensitivity improved by up to an order of magnitude compared to existing instruments such as H.E.S.S., MAGIC and VERITAS. CTA is expected to discover hundreds of new TeV gammaray sources, allowing it to significantly advance our understanding of the origin of cosmic rays, to probe much larger distances in the universe, and to search for WIMP dark matter with unprecedented sensitivity in TeV mass range.
The development of CTA is being carried out by a worldwide consortium of scientists from
32 countries. Consortium scientists have developed the core scientific programme of CTA and
institutes of the Consortium are expected to provide the bulk of the CTA components. The
construction of CTA is overseen by the CTA Observatory that will in the future manage
observatory operations, the guest observer programme, and data dissemination.
This talk will review the scientific motivation for CTA, focusing on the key science projects
that form the core programme of research. The talk will outline the design of CTA, including the
science drivers, overall concept, performance optimization, and array layouts. The current
status of CTA, including sites, prototype telescope progress, and steps forward will also be
described. Keywords: CTA, next-generation gamma-ray observatory, gamma rays Published in RUNG: 16.02.2018; Views: 3902; Downloads: 140 Full text (1,35 MB) |

90. Very high-energy gamma-ray signature of ultrahigh-energy cosmic-ray acceleration in Centaurus AJagdish Joshi, Marlui Miranda, Lili Yang, Soebur Razzaque, 2017, published scientific conference contribution abstract Abstract: The association of at least a dozen ultrahigh-energy cosmic-ray (UHECR) events with energy 54 EeV or higher detected by the Pierre Auger Observatory from the direction of Centaurus-A, the nearest radio galaxy, supports the scenario of UHECR acceleration in the jets of radio galaxies. Multiwavelength observations of Centaurus-A suggest that the inner jet is likely the site for particle acceleration, which emits in X-ray to very high-energy (VHE) gamma-ray. We model broadband spectral energy distribution with emission from shock-accelerated electrons and protons in a combined synchrotron-self-Compton and photo-hadronic scenario. The UHECR flux from Centaurus-A, required to explain Pierre Auger data, successfully explains observed VHE gamma rays as photo-hadronic emission.
