“…In the next future we will see the advent of a new generation of Imaging Atmospheric Telescopes (IACTs) for gamma-ray observations, as the Cherenkov Telescope Array (CTA, Actis et al 2011) or the ASTRI 3 Mini-Array (Scuderi et al, 2022). If compared with water Cherenkov detectors, as LHAASO or Tibet As-γ, they will operate in a reduced energy range but with a much better sensitivity and resolution.…”

Pulsar wind nebulae are fascinating systems, and archetypal sources for high-energy astrophysics in general. Due to their vicinity, brightness, to the fact that they shine at multi-wavelengths, and especially to their long-living emission at gamma-rays, modelling their properties is particularly important for the correct interpretation of the visible Galaxy. A complication in this respect is the variety of properties and morphologies they show at different ages. Here we discuss the differences among the evolutionary phases of pulsar wind nebulae, how they have been modeled in the past and what progresses have been recently made. We approach the discussion from a phenomenological, theoretical (especially numerical) and observational point of view, with particular attention to the most recent results and open questions about the physics of such intriguing sources.

“…Future observations with the next-generation Imaging Atmospheric Cherenkov Telescopes, as ASTRI Mini-Array [65][66][67][68][69] or Cherenkov Telescope Array (CTA) [70,71] would be important to reveal any point source populations that can contribute to gamma-rays above a few GeV from these GMCs. The estimated neutrino flux in this work for the GMCs under consideration has been compared with the current IceCube sensitivity in figure 8.…”

Recently, the Fermi-LAT gamma-ray satellite has detected six Giant Molecular Clouds (GMCs) located in the Gould Belt and the Aquila Rift regions. In half of these objects (Taurus, Orion A, Orion B), the observed gamma-ray spectrum can be explained using the Galactic diffused Cosmic Ray (CR) interactions with the gas environments. In the remaining three GMCs (Rho Oph, Aquila Rift, Cepheus), the origin of the gamma-ray spectrum is still not well established. We use the GEometry ANd Tracking (GEANT4) simulation framework in order to simulate gamma-ray emission due to CR/GMC interaction in these three objects, taking into account the gas density distribution inside the GMCs. We find that propagation of diffused Galactic CRs inside these GMCs can explain the Fermi-LAT detected gamma-ray spectra. Further, our estimated TeV-PeV fluxes are consistent with the HAWC upper limits, available for the Aquila Rift GMC. As last step, we compute the total neutrino flux estimated for these GMCs and compare it with the IceCube detection sensitivity.

“…In this context, the ASTRI Mini-Array will be fundamental thanks to its unprecedented sensitivity and spatial resolution at E > 10 TeV and its wide FoV. The ASTRI Mini-Array is being built at Teide observatory (Tenerife, Canary Sslands) thanks to an agreement between INAF and the Instituto de Astrofisica de Canarias, IAC [13]. The ASTRI Mini-Array includes Italian (universities of Perugia, Padova, Catania, Genova and the Milano Polytechnic, INFN sections of Roma Tor Vergata and Perugia,) and international partners (University of São Paulo with FAPESP in Brasil and the North Western University in South Africa) and it will have the first 3 telescopes operative within 2023 and it will be completed (all the nine telescopes) in 2025.…”

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.
