Far Infrared Emission from Galaxy Clusters and Early-Type Galaxies
Joel N. Bregman, Caroline V. Cox
Infrared emission has been detected from normal elliptical galaxies and from clusters of galaxies at 60um and 100um with the IRAS satellite. In both cases, the emission has the cha…
Low Mass X-ray Binaries As the Source of the Very Soft X-ray Emission in the X-ray Faintest Early-Type Galaxies
Jimmy A. Irwin, Craig L. Sarazin
The X-ray emission from the faintest X-ray elliptical and S0 galaxies is characterized by a hard ~5 keV component, and a very soft ~0.2 keV component. The hard component has genera…
Extreme Ultraviolet Emission from Clusters of Galaxies: Inverse Compton Radiation from a Relic Population of Cosmic Ray Electrons?
Craig L. Sarazin, Richard Lieu
We suggest that the luminous extreme ultraviolet (EUV) emission which has been detected recently from clusters of galaxies is Inverse Compton (IC) scattering of Cosmic Microwave Ba…
X-Ray Spectral Properties of the Cluster Abell 2029
Craig L. Sarazin, Michael W. Wise, Maxim L. Markevitch
We have analyzed ASCA and ROSAT PSPC spectra and images of the galaxy cluster Abell 2029. The ASCA spectra of the cluster indicate that the gas temperature declines with radius. Th…
The Temperature Structure of 30 Nearby Clusters Observed with ASCA. Similarity of Temperature Profiles
M. Markevitch, W. R. Forman, C. L. Sarazin +1
We present ASCA temperature profiles and, when possible, crude temperature maps for a sample of bright clusters with 0.04<z<0.09. Together with several previously published cluster…
A High Resolution ROSAT X-Ray Study of Abell 4059
Z. Huang, C. L. Sarazin
We have analyzed the ROSAT HRI image and PSPC spectra of Abell~4059. The most striking feature of the X-ray image is the two X-ray holes and an orthogonal X-ray bar in the center o…
