Cold gas in the Perseus cluster core: Excitation of molecular gas in filaments
P. Salomé, F. Combes, Y. Revaz +4
We have recently detected CO lines in the well-known filaments around NGC 1275, the galaxy at the centre of the Perseus cluster of galaxies. These previous observations, with the H…
Discovery of atomic and molecular mid infra-red emission lines in off-nuclear regions of NGC 1275 and NGC 4696 with the Spitzer Space Telescope
R. Johnstone, N. Hatch, G. Ferland +3
We present Spitzer high-resolution spectra of off-nuclear regions in the central cluster galaxies NGC 1275 and NGC 4696 in the Perseus and Centaurus clusters, respectively. Both ob…
Magnetic Fields in the Center of the Perseus Cluster
G. B. Taylor, N. E. Gugliucci, A. C. Fabian +3
We present Very Long Baseline Array (VLBA) observations of the nucleus of NGC 1275, the central, dominant galaxy in the Perseus cluster of galaxies. These are the first observation…
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 low-power nucleus of PKS 1246-410 in the Centaurus Cluster
G. B. Taylor, J. S. Sanders, A. C. Fabian +1
We present Chandra, Very Large Array (VLA), and Very Long Baseline Array (VLBA) observations of the nucleus of NGC 4696, a giant elliptical in the Centaurus cluster of galaxies. Li…
Radio Bubbles in Clusters
R. J. H. Dunn, A. C. Fabian, G. B. Taylor
We extend our earlier work on cluster cores with distinct radio bubbles, adding more active bubbles, i.e. those with Ghz radio emission, to our sample, and also investigating ``gho…
