Complex X-ray spectral behaviour of NGC 4051 in the low flux state
P. Uttley, R. D. Taylor, I. M. McHardy +4
The Narrow Line Seyfert 1 galaxy NGC 4051 was observed in one of its prolonged low-lux states by XMM-Newton in November 2002. Here we present the results of an analysis of EPIC-pn…

Catching NGC4051 in the low state with XMM-Newton
P. Uttley, R. D. Taylor, I. M. McHardy +4
The Narrow Line Seyfert 1 galaxy NGC4051 shows unusual low flux states, lasting several months, when the 2-10 keV X-ray spectrum becomes unusually hard (photon index<1) while the s…
