Multi-epoch X-ray observations of the Seyfert 1.2 galaxy Mrk 79: bulk motion of the illuminating X-ray source

Gallo, Luigi C.; Miniutti, G.; Miller, J. M.; Brenneman, L. W.; Fabian, A. C.; Guainazzi, M.; Reynolds, C. S. (Oxford University Press, 2011-02)

Multi-epoch X-ray spectroscopy (0.3–25 keV) of the Seyfert 1.2 galaxy Mrk 79 (UGC3973) spanning nearly 8 yr and a factor of 3 in broad-band flux are analysed. The data are obtained at seven epochs with either XMM–Newton ...
New constraints on the black hole low/hard state inner accretion flow with NuSTAR

Miller, J. M.; Tomsick, J. A.; Bachetti, M.; Wilkins, D. R.; Boggs, S. E.; Christensen, F. E.; Craig, W. W.; Fabian, A. C.; Grefenstette, B. W.; Hailey, C. J. (American Astronomical Society, 2015-01-20)

We report on an observation of the Galactic black hole candidate GRS 1739−278 during its 2014 outburst, obtained with NuSTAR. The source was captured at the peak of a rising “low/hard” state, at a ﬂux of ~0.3 Crab. A broad, ...
Stellar-mass black hole spin constraints from disk reflection and continuum modeling

Gallo, Luigi C.; Miller, J. M.; Reynolds, C. S.; Fabian, A. C.; Miniutti, G. (American Astronomical SocietyIOP Publishing, 2009-05-20)

Accretion disk reflection spectra, including broad iron emission lines, bear the imprints of the strong Doppler shifts and gravitational redshifts close to black holes. The extremity of these shifts depends on the proximity ...
