Launching Jets in Tidal Disruption Events: Magnetic Flux Advection and Plasma Loading
Rin Oikawa, Yuri Sato
A tidal disruption event (TDE) occurs when a star approaches a black hole (BH) and is disrupted by its tidal forces. Although several hundred TDEs have been identified to date, onl…

Non-uniform particle injection into black hole jets by radiative magnetic reconnection
Rin Oikawa, Kenji Toma, Shigeo S. Kimura
Active galactic nuclei often exhibit highly collimated relativistic plasma outflows launched from the vicinity of their central black holes. One of the key theoretical challenges i…
