The highly variable X-ray spectrum of the luminous Seyfert 1 galaxy 1H 0419-577
K. L. Page, K. A. Pounds, J. N. Reeves +1
An XMM-Newton observation of the luminous Seyfert 1 galaxy 1H 0419-577 is presented. We find that the spectrum is well fitted by a power law of canonical slope (gamma ~ 1.9) and 3…
An XMM-Newton observation of the extreme Narrow Line Seyfert 1 Galaxy, Mrk 359
P. T. O'Brien, K. Page, J. N. Reeves +3
We present XMM-Newton observations of Mrk 359, the first Narrow Line Seyfert 1 galaxy discovered. Even among NLS1s, Mrk 359 is an extreme case with extraordinarily narrow optical e…
Multiwavelength Monitoring of the Narrow-Line Seyfert 1 Galaxy Akn 564. II. Ultraviolet Continuum and Emission-line Variability
S. Collier, D. M. Crenshaw, B. M. Peterson +15
We present results of an intensive two-month campaign of approximately daily spectrophotometric monitoring of the narrow-line Seyfert 1 galaxy Akn 564 with HST. The fractional vari…
An XMM-Newton observation of the luminous Seyfert 1 galaxy Markarian 509
Ken Pounds, James Reeves, Paul O'Brien +3
We present the spectral analysis of an early XMM-Newton observation of the luminous Seyfert 1 galaxy Markarian 509. We find the hard (2-10 keV) continuum slope, including reflectio…
