CONFERENCE SERIES | Volume: | XIV International Conference on Topics in Astroparticle and Underground Physics (TAUP 2015) | Number: | 718 | Issue: | 5 | First Page: | 052004 | Abstract: | ASTRI (“Astronomia a Specchi con Tecnologia Replicante Italiana”) is a flagship project of the Italian Ministry of Research (MIUR), devoted to the realization, operation and scientific validation of an end-to-end prototype for the Small Size Telescope (SST) envisaged to become part of the Cherenkov Telescope Array (CTA). The ASTRI SST-2M telescope prototype is characterized by a dual mirror, Schwarzschild-Couder optical design and a compact camera based on silicon photo-multipliers. It will be sensitive to multi-TeV very high energy (VHE) gamma rays up to 100 TeV, with a PSF ~ 6’ and a wide (9.6°) unaberrated optical field of view. Right after validation of the design in single-dish observations at the Serra La Nave site (Sicily, Italy) during 2015, the ASTRI collaboration will be able to start deployment, at the final CTA southern site, of the ASTRI mini-array, proposed to constitute the very first CTA precursor. Counting 9 ASTRI SST-2M telescopes, the ASTRI mini-array will overtake current IACT systems in differential sensitivity above 5 TeV, thus allowing unprecedented observations of known and predicted bright TeV emitters in this band, including some extragalactic sources such as extreme high-peaked BL Lacs with hard spectra. We exploited the ASTRI scientific simulator ASTRIsim in order to understand the feasibility of observations tackling blazar and cosmic ray physics, including discrimination of hadronic and leptonic scenarios for the VHE emission from BL Lac relativistic jets and indirect measurements of the intergalactic magnetic field and of the extragalactic background light. We selected favorable targets, outlining observation modes, exposure times, multi-wavelength coverage needed and the results expected. Moreover, the perspectives for observation of effects due to the existence of axion-like particles or to Lorentz invariance violations have been investigated. | Conference Name: | XIV International Conference on Topics in Astroparticle and Underground Physics (TAUP 2015) | Conference Place: | Torino, Italy | Conference Date: | 7 - 11 September, 2015 | URI: | http://hdl.handle.net/20.500.12386/26396 | URL: | https://iopscience.iop.org/article/10.1088/1742-6596/718/5/052004 | ISSN: | 1742-6588 | DOI: | 10.1088/1742-6596/718/5/052004 | Bibcode ADS: | 2016JPhCS.718e2004B | Fulltext: | open |
