A theoretical study of the time-lags due to Comptonization and the constraints on the X-ray corona in AGN
W. Zhang, I. E. Papadakis, M. Dovčiak +2
We study the Fourier time-lags due to the Comptonization of disc-emitted photons in a spherical, uniform, and stationary X-ray corona, which located on the rotational axis of the b…
Polarization constraints on the X-ray corona in Seyfert Galaxies: MCG-05-23-16
A. Marinucci, F. Muleri, M. Dovčiak +97
We report on the first observation of a radio-quiet Active Galactic Nucleus (AGN) using polarized X-rays: the Seyfert 1.9 galaxy MCG-05-23-16. This source was pointed with the Imag…
The peculiar spectral evolution of the new X-ray transient MAXI J0637-430
R. C. Ma, R. Soria, L. Tao +15
We studied the transient Galactic black hole candidate MAXI J0637-430 with data from Insight-HXMT, Swift and XMM-Newton. The broad-band X-ray observations from Insight-HXMT help us…
Response of the Fe K_alpha line emission to the X-ray continuum variability in the changing-look active galactic nucleus NGC 1566
W. C. Liang, X. W. Shu, J. X. Wang +5
NGC 1566 is a changing look AGN known to exhibit recurrent X-ray outbursts with each lasting for several years. The most recent X-ray outburst is observed on 2018, with a substanti…
