Oxygen Absorption in M87: Evidence for a Warm+Hot ISM
David A. Buote
We present a re-analysis of the ROSAT PSPC data within the central 100 kpc of M87 to search for intrinsic oxygen absorption similar to that recently measured in several galaxies an…
Oxygen Absorption in Cooling Flows
David A. Buote
The inhomogeneous cooling flow scenario predicts the existence of large quantities of gas in massive elliptical galaxies, groups, and clusters that have cooled and dropped out of t…
ROSAT Evidence for Intrinsic Oxygen Absorption in Cooling Flow Galaxies and Groups
David A. Buote
Using spatially resolved, deprojected ROSAT PSPC spectra of 10 of the brightest cooling flow galaxies and groups with low Galactic column densities we have detected intrinsic absor…
Iron Gradients in Cooling Flow Galaxies and Groups
David A. Buote
Previous studies of the Fe abundances in the hot gas of galaxies and groups have reported conflicting results with most studies finding very sub-solar Fe abundances that disagree w…
