LOFAR, VLA, and Chandra observations of the Toothbrush galaxy cluster
R. J. van Weeren, G. Brunetti, M. Brüggen +39
We present deep LOFAR observations between 120-181 MHz of the "Toothbrush" (RX J0603.3+4214), a cluster that contains one of the brightest radio relic sources known. Our LOFAR obse…
Chandra observations of the elusive pulsar wind nebula around PSR B0656+14
L. Bîrzan, G. G. Pavlov, O. Kargaltsev
PSR B0656+14 is a middle-aged pulsar with a characteristic age kyr and spin-down power erg s. Using Chandra data, we searched for a pu…
Wide-Band, Low-Frequency Pulse Profiles of 100 Radio Pulsars with LOFAR
M. Pilia, J. W. T. Hessels, B. W. Stappers +84
LOFAR offers the unique capability of observing pulsars across the 10-240 MHz frequency range with a fractional bandwidth of roughly 50%. This spectral range is well-suited for stu…
The Hot and Energetic Universe: AGN feedback in galaxy clusters and groups
J. H. Croston, J. S. Sanders, S. Heinz +25
Mechanical feedback via Active Galactic Nuclei (AGN) jets in the centres of galaxy groups and clusters is a crucial ingredient in current models of galaxy formation and cluster evo…
The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
Kirpal Nandra, Didier Barret, Xavier Barcons +237
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of tw…
