Spin and Relativistic Phenomena Around Black Holes
L. Brenneman, J. M. Miller, K. Nandra +13
Since the seminal work of Penrose (1969) and Blandford & Znajek (1977), it has been realized that black hole spin may be an important energy source in astrophysics. The radio-loud/…
Fundamental Accretion and Ejection Astrophysics
J. M. Miller, M. Nowak, K. Nandra +11
Disk accretion may be the fundamental astrophysical process. Stars and planets form through the accretion of gas in a disk. Black holes and galaxies co-evolve through efficient dis…
Stellar-Mass Black Holes and Their Progenitors
J. M. Miller, P. Uttley, K. Nandra +14
If a black hole has a low spin value, it must double its mass to reach a high spin parameter. Although this is easily accomplished through mergers or accretion in the case of super…
XMM-Newton and Suzaku analysis of the Fe K complex in the Seyfert 1 galaxy Mrk 509
G. Ponti, M. Cappi, C. Vignali +11
We report on partially overlapping XMM-Newton (~260 ks) and Suzaku (~100 ks) observations of the iron K band in the nearby, bright Seyfert 1 galaxy Mrk 509. The source shows a reso…
Unveiling the broad band X-ray continuum and iron line complex in Mkr 841
P. O. Petrucci, G. Ponti, G. Matt +7
Mkr 841 is a bright Seyfert 1 galaxy known to harbor a strong soft excess and a variable K iron line. It has been observed during 3 different periods by XMM for a total cumulate…
Magnetic flares in Active Galactic Nuclei: Modeling the iron Kalpha-line
R. W. Goosmann, B. Czerny, M. Mouchet +5
The X-ray spectra of Active Galactic Nuclei (AGN) are complex and vary rapidly in time as seen in recent observations. Magnetic flares above the accretion disk can account for the…
