On the Robustness of Cool Disc Components in Bright ULXs
J. M. Miller, A. C. Fabian, M. C. Miller
In this letter, we comment on the robustness of putative cool (kT ~ 0.2 keV) accretion disc components in the X-ray spectra of the most luminous (L ~ 10^40 erg/s) ultra-luminous X-…
An explanation for the soft X-ray excess in AGN (Conference proceedings version)
J Crummy, AC Fabian, L Gallo +1
We present a large sample of type 1 AGN spectra taken with XMM-Newton. We fit them with the relativistically blurred photoionized disc model of Ross & Fabian (2005). This model is…
X-ray reflections on AGN
A. C. Fabian
X-ray reflection generates much of the spectral complexity in the X-ray spectra of AGN. It is argued that strong relativistic blurring of the reflection spectrum should commonly be…
An Explanation for the soft X-ray excess in AGN
J Crummy, AC Fabian, L Gallo +1
We present a large sample of type 1 active galactic nuclei (AGN) spectra taken with XMM-Newton, and fit them with both the conventional model (a power law and black body) and the r…
Discovery of a relativistic Fe line in PG 1425+267 with XMM--Newton and study of its short-timescale variability
G. Miniutti, A. C. Fabian
We report results from the XMM-Newton observation of the radio-loud quasar PG 1425+267 (z=0.366). The EPIC-pn data above 2 keV exhibit a double-peaked emission feature in the Fe K…
The extended H-alpha emitting filaments surrounding NGC4696, the central galaxy of the Centaurus cluster
C. S. Crawford, N. A. Hatch, A. C. Fabian +1
We present images of NGC4696, the central galaxy in the Centaurus cluster, showing the large extent of cool filaments which are bright in H-alpha line emission. These filaments sha…
