X-ray absorption by ionized oxygen in ASCA spectra of the infrared quasar IRAS 13349+2438
W. N. Brandt, S. Mathur, C. S. Reynolds +1
We present evidence for X-ray absorption by ionized oxygen in ASCA spectra of the prototype infrared quasar IRAS 13349+2438. This powerful (2E46 erg/s) quasar was studied in detail…
A multi-wavelength study of the Seyfert 1 galaxy MCG-6-30-15
C. S. Reynolds, M. J. Ward, A. C. Fabian +1
We present a multiwaveband spectroscopic study of the nearby Seyfert 1 galaxy MCG-6-30-15. New optical spectra from the Anglo-Australian Telescope are presented which clearly show…
Iron fluorescence from within the innermost stable orbit of black hole accretion disks
Christopher S. Reynolds, Mitchell C. Begelman
The fluorescent iron Ka line is a powerful observational probe of the inner regions of black holes accretion disks. Previous studies have assumed that only material outside the rad…
