Magnetic field configuration favoring X-class solar flares: violation of Joy's and Hale's laws
S. Liu, J. T. Su, M. Zhang +1
We investigate the statistical relationship between magnetic tilt angle and X-class flare productivity using 39 flare-productive active regions that produced 64 X-class flares. By…
A Timescale-Resolved Analysis of the Breathing Effect in Quasar Broad Line Regions
C. -Z. Jiang, J. -X. Wang, H. Sou +1
The single-epoch virial method is a fundamental tool for estimating supermassive black hole (SMBH) masses in large samples of AGNs and has been extensively employed in studies of S…
The origin of X-ray intra-day variability in HBL PKS 2155-304
W. Hu, J. L. Kang, J. X. Wang +2
The origin and physics of X-ray intra-day variability (IDV) in blazars, which is a long-standing issue, is studied by modelling the broad-band X-ray spectrum, the light curves (LCs…
Unraveling the untwisting process and upward mass transfer of a twisted prominence driven by vortex motion
X. F. Zhang, G. P. Zhou, C. L. Jin +7
Solar filaments/prominences are common features in the Sun's atmosphere that contain cool chromospheric material suspended within the hot corona. However, the intricate topology of…
Characterization of Kepler targets based on medium-resolution LAMOST spectra analyzed with ROTFIT
A. Frasca, J. Molenda-Zakowicz, J. Alonso-Santiago +7
In this work we present the results of our analysis of 16,300 medium-resolution LAMOST spectra of late-type stars in the Kepler field with the aim of determining the stellar parame…
Variability-selected low-luminosity active galactic nuclei candidates in the 7 Ms Chandra Deep Field-South
N. Ding, B. Luo, W. N. Brandt +13
In deep X-ray surveys, active galactic nuclei (AGNs) with a broad range of luminosities have been identified. However, cosmologically distant low-luminosity AGN (LLAGN, $L_{\mathrm…
