- 요약Neutrinos in the Very-High Energy (VHE) range (a 10 PeV) and Ultra-High Energy (UHE) range (aEeV) have not been detected. Extending the observation of neutrinos at these energy ranges would enable the exploration of the most energetic processes in the Universe, testing the limits of the Standard Model, and potentially providing evidence related to the nature of Dark Matter. In the past decade, multiple neutrino observatories have been proposed and developed.This has been driven by the discovery of astrophysical neutrinos by the IceCube Neutrino Observatory (IceCube) and the potential identification of their sources. Ground-based, balloon-borne and space observatories are being developed to expand the current observations of astrophysical neutrinos. The Antarctic Impulsive Transient Antenna (ANITA) is particularly relevant to my research.ANITA monitors the Antarctic ice in search of neutrinos using the Askaryan effect. It can detect the radio emission from neutrinos interacting inside the Antarctic ice. ANITA is also sensitive to extensive air showers (EASs) developing in the atmosphere. Events observed by ANITA can be classified as direct detections or reflected detections. ANITA has observed a few anomalous events consistent with direct detections originating from below the Earth's horizon.During its 1st and 3rd flights, ANITA observed events with steep emergence angles. The reconstructed angles of these events are unusually large based on our current understanding of standard model Earth emergence probabilities. The events from ANITA's 4th flight require an explanation for the number of events recorded, which is incompatible with the non-detection of these events by IceCube and Auger if a diffuse flux is assumed. Considering IceCube's lack of detection and ANITA IV's observations, the standard-model explanation of a diffuse neutrino flux is excluded with a " 3σ significance. Follow-up observations on the anomalous events from ANITA IV's flight have not yet been conducted.Interactions of ultra-high energy cosmic rays with matter and radiation create a flux of ultra-high energy astrophysical neutrinos. Those originating from sources too far away to be resolved produce a diffuse flux of neutrinos. Tau neutrinos are not produced in astrophysical processes. When neutrinos travel long distances to reach Earth, they undergo flavor oscillations, resulting in an almost equal flux of the three neutrino flavors.When tau neutrinos pass through the Earth, they can interact inside the Earth and produce a tau lepton through a charged current (CC) interaction. There's a possibility that the tau lepton will escape the Earth and enter the atmosphere. Once in the atmosphere, the tau lepton can cause an extensive air shower (EAS) through its decay products. As these energetic EASs develop, they produce Cherenkov radiation. For the first time, we are attempting to capture images of EASs using the Cherenkov radiation channel from a sub-orbital flight.I worked on the Extreme Universe Space Observatory - Super Pressure Balloon 2 (EUSO-SPB2) project, which took flight on May 13th, 2023. The mission involved 2 telescopes designed to detect EASs: a fluorescence telescope and an IACT. My role was building, characterizing, and operating the IACT on board EUSO-SPB2. Unfortunately, the mission ended prematurely on the night of May 14th, 2023, due to a balloon leak. However, I was able to utilize the observations from the Cherenkov Telescope on board EUSO-SPB2 to investigate anomalous events reported from ANITA-IV.
