Variability In A Low-Mass AGN: Oscillation Or Eruption?

Robbie Webbe, A. J. Young

Following the discovery of a new class of X-ray variability seen in four galaxies, dubbed Quasi-Periodic Eruptions (QPEs), we reconsider the variability seen in the low-mass AGN 2X…

Mapping the X-ray corona evolution of IRAS 13224-3809 with the power spectral density

Poemwai Chainakun, Wasuthep Luangtip, Jiachen Jiang +1

We develop the power spectral density (PSD) model to explain the nature of the X-ray variability in IRAS 13224-3809, including the full effects of the X-ray reverberation due to th…

X-ray timing and spectral analysis of reverberating active galactic nuclei

Stephen Hancock, Andy Young, Poemwai Chainakun

We use the publicly available XMM-Newton archive to select a sample of 20 active galactic nuclei (AGN) known to exhibit reverberation signatures caused by the reflection of X-rays…

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…

Effects of the refractive index of the X-ray corona on the emission lines in AGN

P. Chainakun, A. Watcharangkool, A. J. Young

X-ray reflection from an accretion disc produces characteristic emission lines allowing us to probe the innermost regions in AGN. We investigate these emission lines under a framew…
