The Origin of Underdense Plasma Downflows Associated with Magnetic Reconnection in Solar Flares
Chengcai Shen, Bin Chen, Katharine K. Reeves +3
Magnetic reconnection is a universal process that powers explosive energy release events such as solar flares, geomagnetic substorms, and some astrophysical jets. A characteristic…
Photon emissions from near-horizon extremal and near-extremal Kerr equatorial emitters
Haopeng Yan, Zezhou Hu, Minyong Guo +1
We consider isotropic and monochromatic photon emissions from equatorial emitters moving along future-directed timelike geodesics in the near-horizon extremal Kerr (NHEK) and near-…
QED Effects on Kerr Black Hole Shadows immersed in uniform magnetic fields
Zhen Zhong, Zezhou Hu, Haopeng Yan +2
In this work, taking the QED effect into account, we investigate the shadows of the Kerr black holes immersed in uniform magnetic fields through the numerical backward ray-tracing…
Correspondence of eikonal quasinormal modes and unstable fundamental photon orbits for Kerr-Newman black hole
Peng-Cheng Li, Tsai-Chen Lee, Minyong Guo +1
In this work, we study the relation of the eikonal quasinormal modes (EQNMs) and the unstable fundamental photon orbits (UFPOs) in the Kerr-Newman spacetime. We find that in the ei…
Observability of Zero-angular-momentum Sources Near Kerr Black Holes
Haopeng Yan, Minyong Guo, Bin Chen
We revisit monochromatic and isotropic photon emissions from the zero-angular\linebreak-momentum sources (ZAMSs) near a Kerr black hole. We investigate the escape probability of th…
Plasma Heating Induced by Tadpole-Like Downflows in the Flaring Solar Corona
Tanmoy Samanta, Hui Tian, Bin Chen +4
As one of the most spectacular energy release events in the solar system, solar flares are generally powered by magnetic reconnection in the solar corona. As a result of the re-arr…
Revisiting the shadow of braneworld black holes
Yehui Hou, Minyong Guo, Bin Chen
We revisit the shadows of rotating braneworld black holes in the Randall-Sundrum type II model, by considering not only the metric in the near region of the black hole but also the…
