Extraction method for response functions from X-ray light curves of AGN by optimization algorithm
Sanhanat Deesamutara, Tirawut Worrakitpoonpon, Poemwai Chainakun +4
We introduce a numerical optimization method to extract the X-ray reverberation response functions from the multi-band light curves of the active galactic nuclei. This approach doe…

Constraining black hole spin in PG 1535+547 amidst complex multi-layered absorption
A. Madathil-Pottayil, D. J. Walton, Jiachen Jiang +7
We present a spectroscopic analysis of XMM-Newton and NuSTAR observations of the 'complex' NLS1 PG 1535+547 at redshift . These observations span three epochs: 2002 and 20…

Narrow-Line Seyfert 1 Galaxies Beyond the Local X-ray Universe: An X-ray spectral sample
Jiachen Jiang, Dominic J. Walton, Luigi C. Gallo +8
Narrow-line Seyfert 1 AGNs (NLS1s) represent a unique stage in the black hole growth history, characterised by low black hole masses of approximately - solar masses…
