Spectral Variation of the Seyfert 1 Galaxy MCG-6-30-15 observed with Suzaku (2009)
Miyakawa, Takehiro, Ebisawa, Ken, Terashima, Yuichi, Tsuchihashi, Fuminori, Inoue, Hajime, Zycki, Piotr
We have investigated spectral variation of the Seyfert 1 galaxy MCG-6-30-15 observed with Suzaku in January 2006 for three separate periods spreading over fourteen days. We found that the...
X-ray Emission from Megamaser Galaxy IC 2560 (2005)
Madejski, Greg, Done, Chris, Zycki, Piotr, Greenhill, Lincoln
Observation of the H2O megamaser galaxy IC 2560 with the Chandra Observatory reveals a complex spectrum composed of soft X-ray emission due to multi-temperature thermal plasma, and a hard continuum...
Mueller, Martin, Madejski, Greg, Done, Chris, Zycki, Piotr
For light curves sampled on an uneven grid of observation times, the shape of the power density spectrum (PDS) includes severe distortion effects due to the window function, and simulations of light...

Ultra-luminous Compact X-ray Sources (ULXs) in nearby spiral galaxies and Galactic superluminal jet sources share the common spectral characteristic that they have unusually high disk temperatures...

The Ultra-luminous Compact X-ray Sources (ULXs) in nearby spiral galaxies and the Galactic super-luminal jet sources share the common spectral characteristic that they have extremely high disk...
Relativistic Distortions in the X-ray Spectrum of Cyg X-1 (1998)
We present the first significant detection of relativistic smearing of the X-ray reflection spectrum from the putative accretion disk in the low/hard state of Cyg X-1. The ionization state, and...
Evolution of the accretion flow in Nova Muscae 1991 (1998)
Zycki, Piotr, Done, Chris, Smith, David
We identify the X-Ray reflected component in the Ginga spectra of Nova Muscae 1991, a Black Hole transient system used as the prototype for the recent model of Esin, McClintock & Narayan (1997) based...
Relativistically smeared X-ray reprocessed components in the GINGA spectra of GS 2023+338 (1997)
Zycki, Piotr, Done, Chris, Smith, David
We present results of spectral analysis of Ginga data obtained during the decline phase after the 1989 outburst of GS 2023+338 (V404 Cyg). Our analysis includes detailed modelling of the effects of...
