Predicting the black hole mass and correlations in X-ray reverberating AGN using neural networks
P. Chainakun, I. Fongkaew, S. Hancock +1
We develop neural network models to predict the black hole mass using 22 reverberating AGN samples in the XMM-Newton archive. The model features include the fractional excess varia…
X-ray reverberation models of the disc wind in ultraluminous X-ray source NGC 5408 X-1
W. Luangtip, P. Chainakun, S. Loekkesee +3
Majority of ultraluminous X-ray sources (ULXs) are believed to be super-Eddington objects, providing a nearby prototype for studying an accretion in super-critical regime. In this…
The nature of the extreme X-ray variability in the NLS1 1H 0707-495
M. L. Parker, W. N. Alston, L. Härer +11
We examine archival XMM-Newton data on the extremely variable narrow-line Seyfert 1 (NLS1) active galactic nucleus (AGN) 1H 0707-495. We construct fractional excess variance (Fvar)…
Machine learning application to detect light echoes around black holes
P. Chainakun, N. Mankatwit, P. Thongkonsing +1
X-ray reverberation has become a powerful tool to probe the disc-corona geometry near black holes. Here, we develop Machine Learning (ML) models to extract the X-ray reverberation…
Evolution of the truncated disc and inner hot-flow of GX 339-4
P. Chainakun, W. Luangtip, A. J. Young +2
Aims. We study the changes in geometry of the truncated disc and the inner hot-flow of GX 339-4 by analyzing the Power SpectralDensity (PSD) extracted from six XMM-Newton observati…
Modelling the X-ray power spectra of AGN by using reprocessing echoes from an extended corona
Poemwai Chainakun
Characteristic signatures that X-ray reverberation from an extended corona can manifest in the observed PSD of AGN are investigated. The presence of two X-ray blobs illuminating an…
