Intrinsic absorbers in BL Lac objects: the XMM-Newton view
A. J. Blustin, M. J. Page, G. Branduardi-Raymont
We present XMM-Newton observations of four BL Lac objects (1H1219+301, H1426+428, Markarian 501 and PKS 0548-322), which have been found with past X-ray missions to contain evidenc…
The XMM-Newton HBS28 sample: studying the obscuration in hard X-ray selected AGNs
A. Caccianiga, P. Severgnini, V. Braito +8
This paper presents the analysis of a statistically complete sample of 28 serendipitous X-ray sources selected in 82 pointed XMM-Newton fields down to a count-rate of 0.002 counts…
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…
XMM-Newton RGS spectroscopy of LMC X-3
M. J. Page, R. Soria, K. Wu +3
We present soft X-ray spectroscopy of the black hole binary LMC X-3 from the XMM-Newton Reflection Grating Spectrometer. The observations span the full range of spectral states see…
The obscured QSO 1SAX J1218.9+2958
Nicola Loaring, M. J. Page, G. Ramsay
We present results from XMM-Newton observations of the obscured QSO 1SAX J1218.9+2958. We find that the previously reported optical and soft X-ray counterpart positions are incorre…
