TL;DR: Polarimeters for Energetic Transients (POET) as discussed by the authors is a mission concept designed to t within the envelope of a NASA Small Explorer (SMEX) mission to uncover the energy release mechanism associated with the formation of stellar-mass black holes and investigate the physics of extreme magnetic ields in the vicinity of compact objects.
Journal ArticleDOI

Takao Kitaguchi,Kevin Black,Kevin Black,Teruaki Enoto,Asami Hayato,Joanne E. Hill,Wataru Iwakiri,Philip Kaaret,Tsunefumi Mizuno,Toru Tamagawa +9 more
TL;DR: In this article, a convolutional neural network (CNN) was used to predict the azimuthal angle and 2D position of the initial photoelectron emission from a 2D track image projected along the X-ray incident direction.
Proceedings ArticleDOI

TL;DR: The NSF Firefly CubeSat is a 3U mission designed to perform cutting-edge science, as a secondary payload1,2. Firefly will be the first dedicated mission launched to study Terrestrial Gamma ray Flashes (TGFs), their link to lightning, and their effect in producing energetic electrons that may become stably trapped in the inner radiation belt as discussed by the authors.
