A multi-faceted view of the X-ray spectral variability in Seyfert galaxy Ark 120
Lu-Xin Ren, Jun-Xian Wang, Jia-Lai Kang
Utilizing a range of techniques including multi-band light curves, softness ratio analysis, structure functions, rms spectra, cross-correlation functions, and ratios of spectra fro…
Chandra detects low-luminosity AGN with in nearby (), dwarf and star-forming galaxies
Mainak Singha, Julissa Sarmiento, Sangeeta Malhotra +8
We searched the Chandra and XMM archives for observations of 900 green pea galaxies to find AGN signatures. Green peas are low-mass galaxies with prominent emission lines, similar…
Integrated Study of X-ray Spectrum and Time Lags for HBL Mrk 421 within the Framework of the Multiple-Zone Leptonic Model
Wen Hu, Jia-Lai Kang, Zhen-Yi Cai +3
We present the timing analysis of 10 archived \XMM observations with an exposure of ks of Markarian 421. Mrk 421 is the brightest high-frequency-peaked BL Lac object (HBL) em…
The X-ray high-energy cutoff in Compact Symmetric Object Mrk 348
Mai Liao, Junxian Wang, Jialai Kang +2
Compact radio AGN are thought to be young radio active galactic nuclei (AGN) at the early stage of AGN evolution, thus are ideal laboratory to study the high-energy emission throug…
What can be learnt from a highly informative X-ray occultation event in NGC 6814? A marvellous absorber
Jia-Lai Kang, Jun-Xian Wang, Shu-Qi Fu
A unique X-ray occultation event in NGC 6814 during an XMM-Newton observation in 2016 has been reported, providing useful information of the absorber and the corona. We revisit the…
