Summary: The Schwarzschild-Couder Telescope (SCT) utilizes a dual-mirror optical design and a high-density silicon photomultiplier camera to detect Cherenkov emission. The prototype SCT (pSCT) has a 9.7 m diameter primary mirror and was inaugurated in January 2019. In the first observation campaign in January and February 2020, gamma-ray emission from the Crab Nebula was detected with a statistical significance of 8.6 sigma.

Summary: The study focused on the search for very-high-energy gamma-ray emission from near three supersonic pulsars, with no clear detection of TeV emission from their X-ray or radio signatures so far. Upper limits on TeV flux and luminosity were provided, suggesting at least one of the pulsar tails could be detected in more sensitive observations. The analysis also has implications for understanding the properties of pulsar tails detectable in TeV.

Summary: The article describes a new method that uses sub-threshold event candidates to search for transient events using archival very-high-energy gamma-ray data from IACTs. This method has the potential to be applied to future LIGO/Virgo data releases and other sub-threshold studies for multimessenger transients.

Summary: Two different formalisms for modeling the energy deposition of macroscopically sized quark nuggets were compared, revealing a significant discrepancy in macro luminosity predictions. This finding was used to estimate the sensitivity for macro detection in space-based and suborbital experiments.

Summary: POEMMA aims to accurately observe ultra-high-energy cosmic rays and cosmic neutrinos from space with sensitivity over the full celestial sky. The spacecraft are designed to re-orientate quickly to follow up transient neutrino sources and obtain unparalleled neutrino flux sensitivity. The mission will provide measurements that open new multi-messenger windows onto the most energetic events in the universe, enabling the study of new astrophysics and particle physics at extreme energies.

Summary: This study explores the gamma-ray variability and spectral characteristics of three FSRQs observed at GeV and TeV energies by Fermi-LAT and VERITAS, and explains the GeV flux distributions of the sources using a model based on a stochastic differential equation. The study also analyzes the daily and subdaily variability and gamma-ray energy spectra of the distinct flares identified. Furthermore, the study models the broadband spectral energy distributions of two FSRQs during high-energy flares, providing constraints on the jet Doppler factors and gamma-ray emission region locations. The study also discusses the theoretical constraints on the production of PeV-scale neutrinos during these flares.

Summary: The gamma-ray observations of the binary system HESS J0632 + 057 over a 15-year period from 2004 to 2019 show significant modulation in very high-energy gamma-ray fluxes with a period of 316.7 +/- 4.4 days. Short-timescale variability with flux-decay timescales of less than 20 days at high energies was observed. The correlation between X-ray and gamma-ray emissions was confirmed, but no correlation was found between optical H alpha parameters and fluxes at X-ray or gamma-ray energies.

Summary: HESS J0632+057 belongs to a rare subclass of binary systems that emit gamma rays above 100 GeV. NuSTAR and VERITAS conducted contemporaneous observations during the secondary peak between 2019 December and 2020 February, revealing X-ray spectral evolution and TeV emission. By fitting a leptonic wind-collision model to the multiwavelength spectra data, the study constrained the pulsar spin-down luminosity and the magnetization parameter at the shock. Despite long-term monitoring, no significant variation in emission lines was detected, but analysis of X-ray spectra allowed measurement of higher neutral hydrogen column density at certain phases.

Summary: Gamma-ray astronomy is a key experimental method for testing quantum gravity theories. By combining data from multiple experiments and using likelihood analysis, this study provides constraints on time delays and energy scales, laying the foundation for further research.

Summary: The low-temperature characteristics of GaN p-i-n avalanche photodiodes (APDs) are presented in this study. The devices demonstrate a breakdown voltage of -95V and a temperature dependence of approximately 0.0159 +/- 0.0034 V/K near 300K. At room temperature, the dark-count rate (DCR) for a 75 x 75 μm² device biased at 1% overvoltage is 23.8 MHz. The DCR decreases by half when the temperature is lowered by 50°C. Band-to-band tunneling is identified as the dominant mechanism for DCR generation based on the temperature-dependent characteristics of the DCR.

Summary: In this study, a deep-ultraviolet Al0.6Ga0.4N p-i-n avalanche photodiode (APD) was grown on an AlN bulk substrate using metalorganic chemical vapor deposition. The performance of the APDs with and without ion implantation was compared, and it was found that the devices fabricated with ion implantation showed improved performance in terms of lower dark current density and higher optical gain.
