Suzaku broadband spectroscopy of Swift J1753.5-0127 in the Low-Hard State (2009)
Reynolds, Mark, Miller, Jon, Homan, Jeroen, Miniutti, Giovanni
We present Suzaku observations of the Galactic black hole candidate Swift J1753.5-0127 in the low-hard state. The broadband coverage of Suzaku enables us to detect the source over the energy range...
Constraints on the absorption-dominated model for the X-ray spectrum of MCG-6-30-15 (2009)
Reynolds, Christopher S., Fabian, Andrew C., Brenneman, Laura W., Miniutti, Giovanni, Uttley, Phil, Gallo, Luigi C.
Complexities in the X-ray spectrum of the nearby Seyfert 1.2 galaxy MCG-6-30-15 are commonly interpreted in terms of a broad iron line and the associated Compton reflection hump from the innermost...
Grupe, Dirk, Komossa, Stefanie, Gallo, Luigi C., Fabian, Andrew C., Larsson, Josefin, Pradhan, Anil K., ...
We report the discovery of strong soft X-ray emission lines and a hard continuum above 2 keV in the Narrow-Line Seyfert 1 galaxy Mrk 335 during an extremely low X-ray flux state. Mrk 335 was observed...

Wide-band spectroscopy of the Compton thick Seyfert 2 galaxy Mrk 3 with Suzaku (2007)
Awaki, Hisamitsu, Anabuki, Naohisa, Fukazawa, Yasuchi, Gallo, Luigi, Ikeda, Shinya, Isobe, Naoki, ...
We obtained a wide-band spectrum of the Compton-thick Seyfert 2 galaxy Mrk 3 with Suzaku. The observed spectrum was clearly resolved into weak, soft power-law emission, a heavily absorbed power-law...

Revealing the high energy emission from the obscured Seyfert galaxy MCG−5–23–16 with Suzaku (2007)
Reeves, James N., Awaki, Hisamitsu, Dewangan, Gulab C., Fabian, Andy C., Fukazawa, Yasushi, Gallo, Luigi, ...
Suzaku observation of 1H0707-495: puzzling spectral drop around 7 keV (2007)
Hayashida, Kiyoshi, Anabuki, Naohisa, Gallo, Luigi, Iwasawa, Kazushi, Tanaka, Yasuo, Miniutti, Giovanni, ...
The long Suzaku observation of MCG-6-30-15 (2007)
Miniutti, Giovanni, Fabian, Andrew C., Crummy, Jamie, Larsson, Josefin, Anabuki, Naohisa, Fukazawa, Yasushi, ...
Revealing the High Energy Emission from the Obscured Seyfert Galaxy MCG -5-23-16 with Suzaku (2006)
Reeves, James N., Awaki, Hisamitsu, Dewangan, Gulab C., Fabian, Andy C., Fukazawa, Yasushi, Gallo, Luigi, ...
We report on a 100 ks Suzaku observation of the bright, nearby (z=0.008486) Seyfert 1.9 galaxy MCG -5-23-16. The broad-band (0.4-100 keV) X-ray spectrum allows us to determine the nature of the high...
Miniutti, Giovanni, Fabian, Andrew C., Anabuki, Naohisa, Crummy, Jamie, Fukazawa, Yasushi, Gallo, Luigi, ...
Suzaku has, for the first time, enabled the hard X-ray variability of the Seyfert 1 galaxy MCG-6-30-15 to be measured. The variability in the 14-45 keV band, which is dominated by a strong reflection...
The X-ray spectra of accreting Kerr black holes (2005)
Fabian, Andrew C., Miniutti, Giovanni
The relativistic broad iron lines seen in the X-ray spectra of several active galaxies and Galactic black hole systems are reviewed. Most such objects require emission from within the innermost...
The XMM-Newton view of Mrk3 and IXO30 (2005)
Bianchi, Stefano, Miniutti, Giovanni, Fabian, Andrew C., Iwasawa, Kazushi
We present the analysis of the XMM-Newton EPIC pn spectrum of the Seyfert 2 galaxy, Mrk3. We confirm that the source is dominated by a pure Compton reflection component and an iron K$\alpha$ line,...
The Simon and Simon-Mars Tensors for Stationary Einstein-Maxwell Fields (2004)
Bini, Donato, Cherubini, Christian, Jantzen, Robert T., Miniutti, Giovanni
Modulo conventional scale factors, the Simon and Simon-Mars tensors are defined for stationary vacuum spacetimes so that their equality follows from the Bianchi identities of the second kind. In the...
Gravitational waves from newly born, hot neutron stars (2002)
Ferrari, Valeria, Miniutti, Giovanni, Pons, Jose' A.
We study the gravitational radiation associated to the non--radial oscillations of newly born, hot neutron stars. The frequencies and damping times of the relevant quasi--normal modes are computed...
The Cotton, Simon-Mars and Cotton-York Tensors in Stationary Spacetimes (2001)
Bini, Donato, Jantzen, Robert T, Miniutti, Giovanni
The Cotton-York and Simon-Mars tensors in stationary vacuum spacetimes are studied in the language of the congruence approach pioneered by Hawking and Ellis. Their relationships with the Papapetrou...
