X-ray time delays in the Narrow Line Seyfert 1 galaxy PG 1244+026

William Alston, Chris Done, Simon Vaughan

We analyse the X-ray time-lags in the Narrow Line Seyfert 1 (NLS1) galaxy PG 1244+026 ( $M_{BH} \sim 1 0^{7} M_{sun}$ , $L / L_{Edd} \sim 1$ ). The time delay between the soft (0…

The flux-dependent X-ray time lags in NGC 4051

W. N. Alston, S. Vaughan, P. Uttley

We present an analysis of the X-ray time lags for the highly variable Seyfert 1 galaxy NGC 4051, based on a series of XMM-Newton observations taken in 2009. We investigate the Four…
