This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges

Numerical Simulations for Optimizing Small Satellite Constellations for TGF Studies
Abstract The detection of Terrestrial Gamma ray Flashes (TGFs) from space is mostly made by astrophysics satellites, which only provide single‐point measurements. Future TGF missions could consist in performing simultaneous detection by a detector array in space.

Search for Synchrotron Pair Echo Emission Following KM3-230213A
The KM3NeT Collaboration has recently reported the detection of an extraordinary ultrahigh-energy (HE) neutrino event with an energy of 220 PeV. UHE neutrinos and gamma rays are coproduced in UHE cosmic-ray interactions.

Review on Uniaxial Negative Thermal Expansion of Tr‐Zr Superconductors
In this paper, we review recent research progress of a study of uniaxial negative thermal expansion (NTE) along the c‐axis with transition (Tr) metal zirconide TrZr2 and TrZr3 superconductors. We introduce the unique thermal expansion properties of TrZr2 and TrZr3 and the flexibility of controlling thermal expansion properties.

Physics from Time Variability of the VHE Blazar PKS 2155-304 [PDF]
Blazars are the principal extragalactic sources of very high energy gamma-ray emission in the Universe. These objects constitute a sub-class of Active Galactic Nuclei whose emission is dominated by Doppler boosted non-thermal radiation from plasma ...

Initial Thermal States of Super‐Earth Exoplanets and Implications for Early Dynamos
Abstract The accretion of Earth and the formation of a metallic core released a large amount of primordial heat and may have enabled its evolution into a habitable world. Metal‐silicate segregation likely occurs in super‐Earth exoplanets as well, but its influence on their initial thermal states has not been fully examined.
