Scientific Rationale

Although celes,al sources emi1ng in the few tens of GeV up to a few TeV are being thoroughly
inves,gated by imaging atmospheric Cherenkov telescope arrays such as H.E.S.S., MAGIC, and
VERITAS, at higher energies, up to a few PeV, more suitable instrumenta,on is required to detect
ultra-high-energy photons, such as extensive air shower arrays, as HAWC, LHAASO, Tibet AS-.

The Italian Na,onal Ins,tute for Astrophysics has recently become the leader of an interna,onal project,
the ASTRI Mini-Array, to install and operate an array of nine dual-mirror Cherenkov telescopes at the
Observatorio del Teide, in Spain, star,ng the early science opera,ons already in 2025. The ASTRI
Mini-Array is expected to span a wide range of energies (1–200 TeV), with a large field of view
(approximately 10 degrees) and an angular and energy resolu,on of ∼3 arcmin and ∼10%,
respec,vely.

The first four years of opera,ons will be dedicated to the exploita,on of ASTRI Core
Science, with a limited selec,on of very deep poin,ngs to address some of the fundamental
ques,ons on the origin of cosmic rays, cosmology, and fundamental physics, the ,me-domain
astrophysics and non -ray studies (e.g., stellar intensity interferometry and direct measurements of
cosmic rays). Subsequently, four more years will be dedicated to ASTRI Observatory Science, open
to the scien,fic community through the submission of observa,onal proposals selected on a
compe,,ve basis. At the same ,me, up to 40 telescopes based on the same op,cal design of the
ASTRI Mini-Array ones will be installed at the southern site of the forthcoming Cherenkov Telescope
Array Observatory, to cons,tute its array of Small Sized Telescopes, capable of exploring the very
high energy gamma-ray sky above several TeV with unprecedented sensi,vity. This conference will
address both the technological and scien,fic aspects of small-sized telescopes for CTAO and ASTRI,
considering the synergies with current and upcoming observational facilities.
