Journal ArticleDOI
Broad iron L line and X-ray reverberation in 1H0707-495
Abderahmen Zoghbi,A. C. Fabian,Phil Uttley,Giovanni Miniutti,Luigi C. Gallo,Christopher S. Reynolds,Jon M. Miller,Gabriele Ponti +7 more
TL;DR: In this article, a detailed analysis of a long XMM-Newton observation of the narrow-line type 1 Seyfert galaxy 1H0707-495 is presented, including spectral fitting, spectral variability and timing studies.
Journal ArticleDOI
Spectral evolution of magnetic flares and time lags in accreting black hole sources
Juri Poutanen,A. C. Fabian +1 more
TL;DR: In this article, the authors present a model for the short timescale spectral variability of accreting black holes, which describes well the time-averaged spectra as well as temporal characteristics such as power-density spectrum, time/phase lags, and coherence function of Cygnus X-1.
Journal ArticleDOI
The corona contracts in a black-hole transient
Erin Kara,James F. Steiner,A. C. Fabian,Edward M. Cackett,Phil Uttley,Ron Remillard,Keith C. Gendreau,Zaven Arzoumanian,Diego Altamirano,S. Eikenberry,Teruaki Enoto,Jeroen Homan,Joseph Neilsen,Abigail L. Stevens +13 more
TL;DR: In this article, the authors reported that the reverberation time lags between the continuum-emitting corona and the irradiated accretion disk are 6 to 20 times shorter than previously seen.
Journal ArticleDOI
A broad iron line in LMC X-1
James F. Steiner,James F. Steiner,Rubens C. Reis,A. C. Fabian,Ronald A. Remillard,Jeffrey E. McClintock,Lijun Gou,Ryan Cooke,Laura Brenneman,Jeremy S. Sanders +9 more
TL;DR: In this paper, the spin parameter of the black hole in LMC X-1 was constrained by modeling broad relativistic reflection features in a soft disc-dominated spectrum, showing that enhanced Comptonization strengthened disc reflection.
Journal ArticleDOI
Suzaku observations of Markarian 335: evidence for a distributed reflector
Josefin Larsson,Giovanni Miniutti,A. C. Fabian,Jon M. Miller,Christopher S. Reynolds,Gabriele Ponti +5 more
TL;DR: In this article, a model consisting of a power law and two reflectors provides the best fit to the time-averaged spectrum of a 151-ks net exposure Suzaku observation of the narrow line Seyfert 1 galaxy Mrk 335.
