Swift detection of all previously undetected blazars in a micro-wave flux-limited sample of WMAP foreground sources

P. Giommi, M. Capalbi, E. Cavazzuti +19

Almost the totality of the bright foreground sources in the WMAP CMB maps are blazars, a class of sources that show usually also X-ray emission. However, 23 objects in a flux-limit…

The mass-energy budget of the ionised outflow in NGC 7469

A. J. Blustin, G. A. Kriss, T. Holczer +6

Although AGN feedback through ionised winds is of great importance in models of AGN/galaxy coevolution, the mass and energy output via these winds, even in the nearby universe, is…

Anatomy of A Dark Burst - The Afterglow of GRB 060108

S. R. Oates, C. G. Mundell, S. Piranomonte +20

We report the first detection of an optical afterglow of a GRB (060108) that would have been classified as 'dark' in the absence of deep, rapid ground-based optical imaging with th…

Principal component analysis of the X-ray variability in NGC 7469

A. J. Blustin, S. V. Fuerst, G. Branduardi-Raymont +3

We apply Principal Component Analysis (PCA) to study the variability of the X-ray continuum in the Seyfert 1 galaxy NGC 7469. The PCA technique is used to separate out linear compo…

The nature and origin of Seyfert warm absorbers

A. J. Blustin, M. J. Page, S. V. Fuerst +2

We collate the results of recent high resolution X-ray spectroscopic observations of 23 AGN, and use the resulting information to try to provide answers to some of the main open qu…

XMM-Newton observations of the heavily absorbed Seyfert 1 galaxy IC 4329A

K. C. Steenbrugge, J. S. Kaastra, M. Sako +5

We detect seven distinct absorbing systems in the high-resolution X-ray spectrum of the Seyfert 1 galaxy IC 4329A, taken with XMM-Newton. Firstly we detect absorption due to cold g…

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…
