Chandra Observations of the Spectacular A3411-12 Merger Event
Felipe Andrade-Santos, Reinout J. van Weeren, Gabriella Di Gennaro +17
We present deep Chandra observations of A3411-12, a remarkable merging cluster that hosts the most compelling evidence for electron re-acceleration at cluster shocks to date. Using…
Particle re-acceleration and Faraday-complex structures in the RXC J1314.4-2515 galaxy cluster
C. Stuardi, A. Bonafede, D. Wittor +9
Radio relics are sites of electron (re)acceleration in merging galaxy clusters but the mechanism of acceleration and the topology of the magnetic field in and near relics are yet t…
Growth and disruption in the Lyra complex
S. Clavico, S. De Grandi, S. Ghizzardi +16
Nearby clusters of galaxies, z<0.1, are cosmic structures still under formation. Understanding the thermodynamic properties of merging clusters can provide crucial information on h…
NGC 326: X-shaped no more
M. J. Hardcastle, J. H. Croston, T. W. Shimwell +7
We present new 144-MHz LOFAR observations of the prototypical `X-shaped' radio galaxy NGC 326, which show that the formerly known wings of the radio lobes extend smoothly into a la…
Observations of a Pre-Merger Shock in Colliding Clusters of Galaxies
Liyi Gu, Hiroki Akamatsu, Timothy W. Shimwell +10
Clusters of galaxies are the largest known gravitationally-bound structures in the Universe. When clusters collide, they create merger shocks on cosmological scales, which transfor…
Signatures from a merging galaxy cluster and its AGN population: LOFAR observations of Abell 1682
A. O. Clarke, A. M. M. Scaife, T. Shimwell +13
We present LOFAR data from 110--180~MHz of the merging galaxy cluster Abell 1682, alongside archival optical, radio and X-ray data. Our 6 arc-second resolution images at low freque…
