Microwave Imaging of Quasi-periodic Pulsations at Flare Current Sheet
Yuankun Kou, Xin Cheng, Yulei Wang +4
Quasi-periodic pulsations (QPPs) are frequently detected in solar and stellar flares, but the underlying physical mechanisms are still to be ascertained. Here, we show microwave QP…
Numerical Modeling of Energetic Electron Acceleration, Transport, and Emission in Solar Flares: Connecting Loop-top and Footpoint Hard X-Ray Sources
Xiangliang Kong, Bin Chen, Fan Guo +8
The acceleration and transport of energetic electrons during solar flares is one of the outstanding topics in solar physics. Recent X-ray and radio imaging and spectroscopy observa…
Non-thermal Broadening of IRIS Fe XXI Lines Caused by Turbulent Plasma Flows in the Magnetic Reconnection Region During Solar Eruptions
Chengcai Shen, Vanessa Polito, Katharine K. Reeves +3
Magnetic reconnection is the key mechanism for energy release in solar eruptions, where the high-temperature emission is the primary diagnostic for investigating the plasma propert…
Photon emissions from Kerr equatorial geodesic orbits
Yanming Su, Minyong Guo, Haopeng Yan +1
We consider the light emitters moving freely along the geodesics on the equatorial plane near a Kerr black hole and study the observability of these emitters. To do so, we assume t…
Circular orbits and polarized images of charged particles orbiting Kerr black hole with a weak magnetic field
Tsai-Chen Lee, Zezhou Hu, Minyong Guo +1
In this work, we study circular motions of charged particles and their polarized images around the Kerr black hole immersed in a weak magnetic field. We pay special attention to th…
Frequency Agile Solar Radiotelescope: A Next-Generation Radio Telescope for Solar Physics and Space Weather
Dale E. Gary, Bin Chen, James F. Drake +4
The Frequency Agile Solar Radiotelescope (FASR) has been strongly endorsed as a top community priority by both Astronomy & Astrophysics Decadal Surveys and Solar & Space Physics De…
Image of Kerr-Melvin black hole with thin accretion disk
Yehui Hou, Zhenyu Zhang, Haopeng Yan +2
In this present work, we study the observational appearance of Kerr-Melvin black hole (KMBH) illuminated by an accretion disk. The accretion disk is assumed to be located on the eq…
Shadows of Kerr black holes with a Gaussian-distributed plasma in the polar direction
Zhenyu Zhang, Haopeng Yan, Minyong Guo +1
In this work, we study the shadow of Kerr black hole surrounded by an axisymmetric plasma, whose density takes a Gaussian distribution in the polar direction. Along the radial dire…
Modeling Electron Acceleration and Transport in the Early Impulsive Phase of the 2017 September 10 Solar Flare
Xiaocan Li, Fan Guo, Bin Chen +2
The X8.2-class limb flare on September 10, 2017 is among the best studied solar flare events owing to its great similarity to the standard flare model and the broad coverage by mul…
Implications for additional plasma heating driving the extreme-ultraviolet late phase of a solar flare with microwave imaging spectroscopy
Jiale Zhang, Bin Chen, Sijie Yu +6
Extreme-ultraviolet late phase (ELP) refers to the second extreme-ultraviolet (EUV) radiation enhancement observed in certain solar flares, which usually occurs tens of minutes to…
Analytic Kludge Waveforms for Extreme Mass Ratio Inspirals of Charged Object around Kerr-Newman Black Hole
Tieguang Zi, Ziqi Zhou, Hai-Tian Wang +3
We derive the approximate, ``analytic-kludge'' (AK) waveforms for the inspiral of a charged stellar-mass compact object (CO) into a charged massive Kerr-Newman (KN) black hole (BH)…
Polarized Images of Synchrotron Radiations in Curved Spacetime
Zezhou Hu, Yehui Hou, Haopeng Yan +2
In this work, we derive two formulas encoding the polarization direction and luminosity of synchrotron radiations from the moving electrons in curved spacetime under the geometric…
A model of double coronal hard X-ray sources in solar flares
Xiangliang Kong, Jing Ye, Bin Chen +6
A number of double coronal X-ray sources have been observed during solar flares by RHESSI, where the two sources reside at different sides of the inferred reconnection site. Howeve…
