Polarization Diagnostics for Cool Core Cluster Emission Lines
William B. Sparks, James E. Pringle, Robert F. Carswell +6
The nature of the interaction between low-excitation gas filaments at ~10^4 K, seen in optical line emission, and diffuse X-ray emitting coronal gas at ~10^7 K in the centers of ga…
Hundred Thousand Degree Gas in the Virgo Cluster of Galaxies
W. B. Sparks, J. E. Pringle, R. F. Carswell +6
The physical relationship between low-excitation gas filaments at ~10^4 K, seen in optical line emission, and diffuse X-ray emitting coronal gas at ~10^7 K in the centers of many g…
On Identifying the Progenitors of Type Ia Supernovae
Mario Livio, J. E. Pringle
We propose two new means of identifying the main class of progenitors of Type Ia supernovae--single or double degenerate: (i) If the range of supernova properties is significantly…
Discovery of CIV Emission Filaments in M87
W. B. Sparks, J. E. Pringle, M. Donahue +4
Gas at intermediate temperature between the hot X-ray emitting coronal gas in galaxies at the centers of galaxy clusters, and the much cooler optical line emitting filaments, yield…
