Long-term performance of SiPMs in space environment measured by GRBAlpha, GRBBeta, and VZLUSAT-2 CubeSats

Jakub Ripa, Filip Munz, Marianna Dafcikova +46

In this work, we report the successful application of silicon photomultipliers (SiPMs) in gamma-ray burst (GRB) detectors used in CubeSats operating in the low Earth orbit (LEO) ra…

Relativistic single-electron wavepacket in quantum electromagnetic fields II: Quantum radiation emitted by a uniformly accelerated electron

Shih-Yuin Lin, Bei-Lok Hu

We compute the quantum radiation emitted by wavepackets of relativistic single electrons, both at rest and undergoing uniform acceleration in the Minkowski vacuum of the electromag…

The Search for $K_{L} \to π^{0} π^{0} γ γ$ and $K_{L} \to π^{0} π^{0} X$ where $X \to 2 γ$ at the KOTO Experiment

J. Redeker, C. Lin, Y. W. Wah +23

We performed searches for $K_{L} \to π^{0} π^{0} X$ where $X$ may be an axion-like particle which promptly decays to two photons, and the first search for $K_{L} \to π^{0} π^{0} γ γ$ …

In-orbit Demonstration of X-ray Pulsar Navigation with NinjaSat

Naoyuki Ota, Takuya Takahashi, Toru Tamagawa +26

This study demonstrated the pulsar navigation capability of the CubeSat X-ray observatory NinjaSat, which is equipped with two Gas Multiplier Counters (GMCs). The GMCs are sensitiv…

Search for Dark Particles in $K_{L}^{0} \to γ X$ at the KOTO Experiment

T. Wu, Y. C. Tung, Y. B. Hsiung +24

We report a search for an invisible particle $X$ in the decay $K_{L}^{0} \to γ X$ ( $X \to invisible$ ), where $X$ can be interpreted as a massless or massive dark photon. N…
