A Chandra X-ray view of Stephan's Quintet: Shocks and Star-formation
E. O'Sullivan, S. Giacintucci, J. M. Vrtilek +2
We use a deep Chandra observation to examine the structure of the hot intra-group medium of the compact group of galaxies Stephan's Quintet. The group is thought to be undergoing a…
Star formation in galaxies falling into clusters along supercluster-scale filaments
Scott C. Porter, Somak Raychaudhury, Kevin A. Pimbblet +1
With the help of a statistical parameter derived from optical spectra, we show that the current star formation rate of a galaxy, falling into a cluster along a supercluster filamen…
A GMRT multifrequency radio study of the isothermal core of the poor galaxy cluster AWM 4
S. Giacintucci, J. M. Vrtilek, M. Murgia +7
We present a detailed radio morphological study and spectral analysis of the wide-angle-tail radio source 4C +24.36 associated with the dominant galaxy in the relaxed galaxy cluste…
The Distribution of Dark Matter in the Halo of the early-type galaxy NGC 4636
Dalia Chakrabarty, Somak Raychaudhury
We present the density structure of dark matter in the outer parts (to about 7 effective radii) of the elliptical galaxy NGC 4636, from the radial velocities of 174 globular cluste…
Evidence for Non-Hydrostatic Gas Motions in the Hot ISM of Centaurus A
R. P. Kraft, M. J. Hardcastle, G. R. Sivakoff +16
We present preliminary results from a deep (600 ks) {\em Chandra} observation of the hot interstellar medium of the nearby early-type galaxy Centaurus A (Cen A). We find a surface…
Globular Clusters and X-ray Point Sources in Centaurus A (NGC 5128)
Kristin A. Woodley, Somak Raychaudhury, Ralph P. Kraft +6
We detect 353 X-ray point sources, mostly low-mass X-ray binaries (LMXBs), in four Chandra observations of Centaurus A (NGC 5128), the nearest giant early-type galaxy, and correlat…
