“…The parametrization presented here improves the precision in the description of the angular distribution of Cherenkov light in comparison to models found in previous publications [8,24,26]. Beside the needed update of the parametrizations concerning the new shower models made available after the previous works, this paper aims at the improvement of the precision requested by the new generation of experiments [7,19] and at the refinement demanded by the new uses of Cherenkov light as the main signal source in FD analyses [15,16]. Moreover, a unified view of the two regimes is presented for the first time.…”

“…Traditionally, Cherenkov light was considered as an unwanted noise in the FD measurements [13], but recently the Cherenkov light seen by FDs has been used as signal to detect showers with energies down to 2 PeV [14][15][16]. Direct Cherenkov light is also used to study UHECR with ground detectors [17,18] and is proposed to be used as an important signal source in future space experiments [19]. The angu-lar distribution of Cherenkov photons in an air shower is an important feature for all UHECR experiments because it determines the lateral spread of light and the balance between fluorescence and Cherenkov-light signals measured by the FDs, including large angles (> 10 • ) and great distances (several km) from the shower axis.…”

The Cherenkov light produced in air showers largely contributes to the signal observed in ground-based gamma-ray and cosmic-ray observatories. Yet, no description of this phenomenon is available covering both regions of small and large angles to the shower axis. To fill this gap, a parametrization of the angular distribution of Cherenkov photons is performed in terms of a physically-motivated parametric function. Model parameters are constrained using simulated gamma-ray and proton showers with energies in the TeV to EeV region. As a result, a new parametrization is obtained that improves the precision of previous works. Results presented here can be used in the reconstruction of showers with imaging Cherenkov telescopes as well as in the reconstruction of shower profiles with fluorescence detectors.

“…The modeled airglow data might contribute to understanding the processes in the interface region between the space environment and Earth's atmosphere. Even more, the absolute values of airglow intensities and the range of their variation are crucial for future missions like EUSO‐SPB2 (Wiencke, 2019) and POEMMA (Anchordoqui et al., 2020; NASA Probe Study report, 2020). These missions are designed to observe extensive air showers induced by ultra‐high energy cosmic rays and to observe Cherenkov light induced by cosmic neutrinos.…”

“…In more optimistic models that assume a R max ⇠ 10 20.5 eV, a second photon bump appears at 1-10 EeV as indicated by the comparison, we show the fluxes of the six-year high-energy starting events (HESE six-year muon neutrino events (orange shaded region) [77], nine-year extremeupper limit [71] measured by IceCube (thick red curve), and the 90% upper limi data from 1 Jan 04 -31 Mar 17 (thin red curve, [72]), as well as the extragalactic observed by Fermi-LAT [80,84], and the differential limit of UHE photons in Auger [75]. For reference, we also show the cosmic-ray spectra measured by TA [35,78,79]. K. Fang for this review.…”

Nature is providing particles with energies exceeding 100 EeV. Their existence imposes immediate questions: Are they ordinary particles, accelerated in extreme astrophysical environments, or are they annihilation or decay products of super-heavy dark matter or other exotic objects? If the particles are accelerated in extreme astrophysical environments, are their sources related to those of high-energy neutrinos, gamma rays, and/or gravitational waves, such as the recently observed mergers of compact objects? The particles can also be used to study physics processes at extreme energies; is Lorentz invariance still valid? Are the particles interacting according to the Standard Model or are there new physics processes? The particles can be used to study hadronic interactions (QCD) in the kinematic forward direction; what is the cross section of protons at center-of-mass energies √ > 100 TeV? These questions are addressed at present by installations like the Telescope Array and the Pierre Auger Observatory. After the year 2030, a next-generation observatory will be needed to study the physics and properties of the highest-energy particles in Nature, building on the knowledge harvested from the existing observatories. It should have an aperture at least an order of magnitude bigger than the existing observatories. Recently, more than 200 scientists from around the world came together to discuss the future of the field of multi-messenger astroparticle physics beyond the year 2030. Ideas have been discussed towards the physics case and possible scenarios for detection concepts of the Global Cosmic Ray Observatory -GCOS. A synopsis of the key results discussed during the brainstorming workshop will be presented.
