Abstract:
'The ASTRI Mini-Array is a system of nine imaging atmospheric Cherenkov telescopes to be deployed at the Observatorio del Teide (Tenerife, Spain). In a first phase, the instrument will be operated as an experiment, with an observation schedule focused on primary science cases at multi-TeV energies (origin of cosmic rays, cosmology and fundamental physics, GRBs and multi-messenger astrophysics). Afterwards, a guest-observer observatory phase will follow, in which other significant targets will be pointed at. In this contribution, we focus on this second phase, presenting the observational feasibility of the most relevant extragalactic gamma-ray emitters (high-synchrotron peaked blazars, Seyfert 2 galaxies, self-interacting dark matter dominated dwarf spheroidal galaxies) and astrophysical processes detectable over long-term time scales that best complement and expand the ASTRI Mini-Array core science. In order to derive our results, detailed simulations have been performed by means of the most up-to-date ASTRI Mini-Array instrument response functions. The prospects of observing extragalactic targets with the ASTRI Mini-Array include the characterization of spectral shape and features of the multi-TeV emission from the analyzed classes of AGN with mid-to-long duration (5 to 500 h) observations, the improvement of the constraints on cross section and lifetime of dark matter particles with 100-h observations of optimal dwarf galaxies, and the possibility to serendipitously detect ancillary sources falling in the same field of view (a few degrees) of the ASTRI Mini-Array main pointings.'
