The Soft and Medium–energy X–ray Variability of Ngc 5548: a Reanalysis of Exosat Observations
We present a detailed cross–correlation (CCF) and power spectrum re–analysis of the X–ray light curves of the bright Seyfert 1 galaxy NGC5548 obtained with EXOSAT. The 0.05–2 keV and 1–4 keV light curves are cross–correlated with the 1–9 keV and 4–9 keV light curves respectively. We discuss how spurious time lags can be introduced by systematic effects related to detector swapping as well as th...
متن کاملTime resolved photoelectron spectroscopy with ultrafast soft x-ray light
2001 This thesis entitled: Time resolved photoelectron spectroscopy with ultrafast soft x-ray light written by Lora Nugent-Glandorf has been approved for the Department of Chemistry and Biochemistry Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentione...
متن کاملX ? Ray Photon Spectroscopy with the Yohkoh Soft X ? Ray Telescope
Individual X ? ray photons in the keV energy range produce hundreds of photoelectrons in a single pixel of a CCD array detector. The number of photoelectrons produced is a linear function of the photon energy, allowing the measurement of spectral information with an imaging detector system. The Yohkoh Soft X ? ray Telescope uses a CCD in an integrating mode and makes temperature estimates from ...
متن کاملOptimum driving a Z-pinch for soft X-Ray lasers
A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...
متن کاملSoft X - ray Spectroscopy of Seyfert 2 Galaxies
Soft X-ray spectroscopy of Seyfert 2 galaxies provides perhaps the best method to probe the possible connection between AGN activity and star formation. Obscuration of powerful radiation from the inferred nucleus allows for detailed study of circumnuclear emission regions. And soft X-ray spectroscopy of these regions allows for robust discrimination between warm gas radiatively-driven by the AG...
