Asymmetric Distribution of the Solar Photospheric Magnetic-Field Values
Gao, Peng-Xin; Li, Ke-Jun; Xu, Jing-Chen
Understanding the characteristics of the solar magnetic field is essential for interpreting solar activities and dynamo. In this research, we investigated the asymmetric distribution of the solar photospheric magnetic-field values, using synoptic charts constructed from space-borne high-resolution magnetograms. It is demonstrated that the Lorentzi…
The Nonrelaxation of Magnetic Field Lines in Solar Wind Magnetic Reconnection Exhausts
Xu, Qi; Xu, Xiaojun; Xu, Jiaying +2 more
We present a case study using data from multiple spacecraft and statistics from the ACE spacecraft to investigate the relaxation of reconnected magnetic field lines in solar wind magnetic reconnection exhausts, which constitute one of the two outflow regions resulting from magnetic reconnection, and which are often characterized by a plasma jet, m…
The Galaxy Environment of Extremely Massive Quasars. I. An Overdensity of Hα Emitters at z = 1.47
Im, Myungshin; Jun, Hyunsung D.; Hyun, Minhee +8 more
We measure a strong excess in the galaxy number density around PG 1630+377, an extremely massive (MBH ≃ 109.7M⊙) quasar at z = 1.475, using near-infrared narrowband imaging. We identify 79 narrow H-band excess objects in a 525 arcmin2 area including the vicinity and surroundings of the quasar. These sour…
