Searching for High Energy, Horizon-scale Emissions from Galactic Black Hole Transients during Quiescence
Lupin Chun-Che Lin, Hung-Yi Pu, Kouichi Hirotani +5
We search for the gamma-ray counterparts of stellar-mass black holes using long-term Fermi archive to investigate the electrostatic acceleration of electrons and positrons in the v…
Enhanced gamma radiation toward the rotation axis from the immediate vicinity of extremely rotating black holes
Yoogeun Song, Hung-Yi Pu, Kouichi Hirotani +3
We investigate the acceleration of electrons and positrons by magnetic-field-aligned electric fields in the polar funnel of an accreting black hole (BH). Applying the pulsar outer-…
Lepton acceleration in the vicinity of the event horizon: Very-high-energy emissions from super-massive black holes
Kouichi Hirotani, Hung-Yi Pu, Lupin Chun-Che Lin +5
Around a rapidly rotating black hole (BH), when the plasma accretion rate is much less than the Eddington rate, the radiatively inefficient accretion flow (RIAF) cannot supply enou…
Benchmarking COSI's detector effects engine
Clio C. Sleator, Steven E. Boggs, Jeng-Lun Chiu +11
The Compton Spectrometer and Imager (COSI) is a balloon-borne gamma-ray (0.2-5 MeV) telescope with inherent sensitivity to polarization. COSI's main goal is to study astrophysical…
The 2016 Super Pressure Balloon flight of the Compton Spectrometer and Imager
Carolyn A. Kierans, Steven E. Boggs, Jeng-Lun Chiu +11
The Compton Spectrometer and Imager (COSI) is a balloon-borne, soft-gamma ray imager, spectrometer, and polarimeter with sensitivity from 0.2 to 5 MeV. Utilizing a compact Compton…
