Hybrid corona and transient soft X-ray lags in Fairall 9
K. Khanthasombat, P. Chainakun, W. Luangtip +2
Fairall 9 is among the most massive Seyfert galaxies exhibiting a strong soft X-ray excess, but it is challenging to probe soft X-ray reverberation lags (if any) due to the long in…

Extracting the X-ray reverberation response functions from the AGN light curves using an autoencoder
Sanhanat Deesamutara, Poemwai Chainakun, Tirawut Worrakitpoonpon +5
We study the X-ray reverberation in active galactic nuclei (AGN) using the variational autoencoder (VAE), which is a machine-learning algorithm widely used for signal processing an…

Parameter dependency on the public X-ray reverberation models kynxilrev and kynrefrev
K. Khanthasombat, P. Chainakun, A. J. Young
We present a comparative study of the constrained parameters of active galactic nuclei (AGN) made by the public X-ray reverberation model kynxilrev and kynrefrev that make use of t…
