“…We note that the ASTRI Mini-Array performance remains almost stable across the 10°FoV, with a degradation at its edge by roughly a factor of two [3,6]. On the other side, the EASs have 2 sr field of view, but their energy and angular resolution in the same energy range as the ASTRI Mini-Array (about 10 TeV) are at least a factor of 3-4 worse, making the ASTRI Mini-Array extremely competitive in studying the morphology of extended sources, crowded fields, and accurately monitoring multiple targets in the same pointing.…”

“…The energy range above a few TeVs is the right spot for the ASTRI Mini-Array. In [3] we simulated a GRB 190114C-like source with a prompt energy of 3 × 10 53 erg placed at = 0.1 and = 0.25 (GRB 221009A is at = 0.15) and we predicted the capability to detect photons up to and above 10 TeV within few minutes from the burst.…”

“…In particular, the ASTRI Mini-Array is expected to improve the MAGIC sensitivity in the North for E > few TeV and, at the same time, to operate for a few years before the full completion of CTAO North. Therefore, the ASTRI Mini-Array will have a vast discovery space in the field of extreme gamma-rays, up to 100 TeV and beyond, as described in [3][4][5]. We can summarize the main ASTRI Mini-Array performance as follows: wide field of view (FoV) of about 10°; energy range from 1 TeV up to 200 TeV, angular resolution ∼ 3 ′ at 10 TeV and energy resolution ∼ 10% at 10 TeV .…”

Celestial sources emitting at high-energy (HE, E >100 MeV) and at very high-energy (VHE, E >100 GeV) gamma-rays are of the order of a few thousands and a few hundreds, respectively. On the other hand, the number of sources emitting at ultra high-energy (UHE, E > several tens of TeV) gamma-rays are just a few dozens, and are currently being investigated by means of both ground-based imaging atmospheric Cherenkov telescopes (IACTs) and particle shower arrays. These rare VHE and UHE sources represent a new frontier in astrophysics. An array composed of nine ASTRI Cherenkov telescopes is under construction at the Observatorio del Teide (Tenerife, Spain). The ASTRI Mini-Array aims at providing robust answers to a few selected open questions in the VHE and UHE domains. The scientific program during the first four observing years will be devoted to the following Core Science topics: the origin of cosmic rays, the extra-galactic background light and the study of fundamental physics, the novel field in the VHE domain of gamma-ray bursts and multi-messenger transients, and finally the use of the ASTRI Mini-Array to investigate ultra high-energy cosmic rays and to undertake stellar intensity interferometry studies. We review the scientific prospects assessed through dedicated simulations, proving the potential of the ASTRI Mini-Array in pursuing breakthrough discoveries and discuss the synergies with current and future VHE facilities in the Northern hemisphere, such as MAGIC, LHAASO, HAWC, Tibet AS-, and CTAO-N.

“…Its angular resolution (0.05 • at 10 TeV) will be fundamental for a morphological reconstruction of extended sources like SNRs, PWNe and MSCs. Therefore, soon, the ASTRI Mini-Array will have a vast discovery space in the field of extreme 𝛾-rays, up to 100 TeV and beyond [14][15][16].…”

Despite the enormous efforts done in very recent years, both theoretically and experimentally, the basic three questions about the cosmic rays origin remain without clear answers: what are their sources, how are they accelerated, how do they propagate? Gamma-ray astronomy plays a fundamental role in this field. Both relativistic protons and electrons can emit in the 𝛾ray band through different processes, but only the detection of hadronic 𝛾-ray emission can probe the acceleration of cosmic rays. In particular, due to the Klein-Nishina suppression of inverse Comptonemission at the highest energies, the detection of 𝛾-ray emission above 100 TeV was expected to provide firm proof of the acceleration of PeV hadrons. However, the recent results published by the LHAASO collaboration revealed the existence of several PeV sources likely related to PWNe, well known leptonic factories (e.g. the Crab Nebula for all). As a consequence, a 𝛾-ray detection at PeV energies may no longer be the final proof of hadronic acceleration. However, the limited angular resolution of LHAASO makes associations uncertain and more detailed and deeper studies are needed. In this context, the ASTRI Mini-Array, with its unprecedented sensitivity and angular resolution at E>10 TeV, not only can extend the gamma-ray spectra of candidate Cosmic Ray factories but could help to distinguish emission regions from PWNe and other LHAASO sources, shedding light on the nature of the highest energy emission.

TeV haloes are a recently discovered class of very high energy gamma-ray emitters. These sources consist of extended regions of multi-TeV emission, originally observed around the two well-known and nearby pulsars, Geminga and PSR B0656+14 (Monogem), and possibly, with different degrees of confidence, around few more objects with similar age. Since their discovery, TeV haloes have raised much interest in a large part of the scientific community, for the implications their presence can have on a broad range of topics spanning from pulsar physics to cosmic ray physics and dark matter indirect searches. In this article, we review the reasons of interest for TeV haloes and the current status of observations. We discuss the proposed theoretical models and their implications, and conclude with an overlook on the prospects for better understanding this phenomenon.
