Interaction between the intergalactic medium and central radio source in the NGC 4261 group of galaxies
Ewan O'Sullivan, Diana M. Worrall, Mark Birkinshaw +4
Using observations from the Chandra and XMM-Newton X-ray observatories, we examine the interaction between the intra-group medium and central radio source in the nearby NGC 4261 ga…
Heating the hot atmospheres of galaxy groups and clusters with cavities: the relationship between jet power and low-frequency radio emission
Ewan O'Sullivan, Simona Giacintucci, Laurence P. David +4
We present scaling relations between jet power and radio power measured using the Giant Metrewave Radio Telescope (GMRT), Chandra and XMM-Newton, for a sample of 9 galaxy groups co…
A combined low-radio frequency/X-ray study of galaxy groups I. Giant Metrewave Radio Telescope observations at 235 MHz and 610 MHz
Simona Giacintucci, Ewan O'Sullivan, Jan Vrtilek +12
We present new Giant Metrewave Radio Telescope observations at 235 MHz and 610 MHz of 18 X-ray bright galaxy groups. These observations are part of an extended project, presented h…
