Kepler Observations of Rapid Optical Variability in Active Galactic Nuclei
Richard F. Mushotzky, Rick Edelson, Wayne H. Baumgartner +1
Over three quarters in 2010-2011, Kepler monitored optical emission from four active galactic nuclei (AGN) with ~30 min sampling, >90% duty cycle, and <~0.1% repeatability. These d…
Oxygen Abundances in the Milky Way Using X-ray Absorption Measurements Towards Galaxy Clusters
Wayne H. Baumgartner, Richard F. Mushotzky
We present measurements of the oxygen abundance of the Milky Way's ISM by observing the K-shell X-ray photoionization edge towards galaxy clusters. This effect is most easily obser…
Intermediate Element Abundances in Galaxy Clusters
W. H. Baumgartner, M. Loewenstein, D. J. Horner +1
We present the average abundances of the intermediate elements obtained by performing a stacked analysis of all the galaxy clusters in the archive of the X-ray telescope ASCA. We d…
