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…

Revealing Hidden Repeaters in the CHIME/FRB Catalog: Semi-Supervised Insights into the Fast Radio Burst Population
N. Mankatwit, P. Thongkonsing, S. Loekkesee +3
Fast radio bursts (FRBs) are millisecond-duration extragalactic transients, observationally classified as repeaters or nonrepeaters. This classification may be biased, as some appa…

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…
