AGN Feedback in groups and clusters of galaxies
S. Raychaudhury, S. Giacintucci, E. O'Sullivan +5
The lack of very cool gas at the cores of groups and clusters of galaxies, even where the cooling time is significantly shorter than the Hubble time, has been interpreted as eviden…
A Joint GMRT/X-ray study of galaxy groups
E. O'Sullivan, S. Giacintucci, J. M. Vrtilek +4
We present results from combined low-frequency radio and X-ray studies of nearby galaxy groups. We consider two main areas: firstly, the evolutionary process from spiral-dominated,…
A statistically-selected Chandra sample of 20 galaxy clusters -- II. Gas properties and cool-core/non-cool core bimodality
Alastair J. R. Sanderson, Ewan O'Sullivan, Trevor J. Ponman +1
We investigate the thermodynamic and chemical structure of the intracluster medium (ICM) across a statistical sample of 20 galaxy clusters analysed with the Chandra X-ray satellite…
