The XMM-Newton view of AGN with intermediate mass black holes
G. Miniutti, G. Ponti, J. E. Greene +3
We have observed with XMM-Newton four radiatively efficient active type 1 galaxies with black hole masses < 10^6 Msun, selected optically from the SDSS. We show here that their sof…
Giant cavities, cooling and metallicity substructure in Abell 2204
J. S. Sanders, A. C. Fabian, G. B. Taylor
We present results from deep Chandra and XMM-Newton observations of the relaxed X-ray luminous galaxy cluster Abell 2204. We detect metallicity inhomogeneities in the intracluster…
INTEGRAL and XMM-Newton Spectroscopy of GX 339-4 During Hard/Soft Intermediate and High/Soft States in the 2007 Outburst
M. D. Caballero-Garcia, J. M. Miller, M. Diaz Trigo +5
We present simultaneous XMM-Newton and INTEGRAL observations of the luminous black hole transient and relativistic jet source GX 339-4. GX 339-4 started an outburst on November of…
Collisional heating as the origin of filament emission in galaxy clusters
G. J. Ferland, A. C. Fabian, N. A. Hatch +4
[Abridged] Photoionization, whether by starlight or other sources, has difficulty in accounting for the observed spectra of the optical filaments that often surround central galaxi…
Simultaneous X-ray/optical/UV snapshots of active galactic nuclei from XMM-Newton: spectral energy distributions for the reverberation mapped sample
R. V. Vasudevan, A. C. Fabian
We employ contemporaneous optical, UV and X-ray observations from the XMM-Newton EPIC-pn and Optical Monitor (OM) archives to present, for the first time, simultaneous spectral ene…
Reflection dominated X-ray spectra of Narrow Line Seyfert 1 Galaxies: Mrk 478 and EXO 1346.2+2645
A. Zoghbi, A. C. Fabian, L. C. Gallo
Multi-epoch XMM-Newton spectra of the two Narrow Line Seyfert 1 (NLS1), Mrk 478 and EXO 1346.2+2645, are presented. The data were fitted with different models, including the relati…
