On the origin and excitation of the extended nebula surrounding NGC 1275
N. A. Hatch, C. S. Crawford, A. C. Fabian +1
We use line-of-sight velocity information on the filamentary emission-line nebula of NGC 1275 to infer a dynamical model of the nebula's flow through the surrounding intracluster g…
A very deep Chandra observation of the Perseus cluster: shocks, ripples and conduction
A. C. Fabian, J. S. Sanders, G. B. Taylor +4
We present the first results from a very deep Chandra X-ray observation of the core of the Perseus cluster of galaxies. A pressure map reveals a clear thick band of high pressure a…
The extended H-alpha emitting filaments surrounding NGC4696, the central galaxy of the Centaurus cluster
C. S. Crawford, N. A. Hatch, A. C. Fabian +1
We present images of NGC4696, the central galaxy in the Centaurus cluster, showing the large extent of cool filaments which are bright in H-alpha line emission. These filaments sha…
X-rays from the Type II quasar in the hyperluminous infrared galaxy IRAS F15307+3252
K. Iwasawa, C. S. Crawford, A. C. Fabian +1
We report the detection of X-ray emission from the hyperluminous infrared galaxy IRAS F15307+3252 at z=0.93 and its properties obtained from XMM-Newton observations. Although the X…
The giant H-alpha/X-ray filament in the cluster of galaxies A1795
C. S. Crawford, J. S. Sanders, A. C. Fabian
The cluster of galaxies A1795 hosts a 46 kpc-long filament at its core, which is clearly visible in the light of H-alpha and X-ray emission. We present optical slit spectroscopy an…
