Extended steep-spectrum radio emission in a galaxy cluster is usually associated with a recent merger. However, given the complex scenario of galaxy cluster mergers, many of the discovered sources hardly fit into the strict boundaries of a precise taxonomy. This is especially true for radio phoenixes that do not have very well defined observational criteria. Radio phoenixes are aged radio galaxy lobes whose emission is reactivated by compression or other mechanisms. Here, we present the… 
Ultra-steep spectrum emission in the merging galaxy cluster Abell 1914
A number of radio observations have revealed the presence of large synchrotron-emitting sources associated with the intra-cluster medium. There is strong observational evidence that the emitting
LOFAR discovery of a 700-kpc remnant radio galaxy at low redshift
Remnant radio galaxies represent the final "dying" phase of radio galaxy evolution, in which the jets are no longer active. Due to their rarity in flux limited samples and the difficulty of
Multi-wavelength Observations of the Dissociative Merger in the Galaxy Cluster CIZA J0107.7+5408
We present results based on X-ray, optical, and radio observations of the massive galaxy cluster CIZA J0107.7+5408. We find that this system is a post core passage, dissociative, binary merger, with
Diffuse Radio Emission from Galaxy Clusters
In a growing number of galaxy clusters diffuse extended radio sources have been found. These sources are not directly associated with individual cluster galaxies. The radio emission reveal the
Radio relic and the diffuse emission trail discovered in low-mass galaxy cluster Abell 1697
We report the discovery of a putative radio relic, 830 kpc in length, and found towards the outskirts of galaxy cluster Abell 1697 (z = 0.181), using the LOFAR Two Meter Sky Survey at 144 MHz. An
A radio ridge connecting two galaxy clusters in a filament of the cosmic web
Simulations are performed to show that a volume-filling distribution of weak shocks may reaccelerate a preexisting population of relativistic particles, producing emission at radio wavelengths that illuminates the magnetic ridge.
Gentle reenergization of electrons in merging galaxy clusters
It is proposed that the interplay between radio-emitting plasma and the perturbed intracluster medium can gently reenergize relativistic particles initially injected by active galactic nuclei to maintain electrons at higher energies than radiative aging would allow.
Merging Cluster Collaboration: Optical and Spectroscopic Survey of a Radio-selected Sample of 29 Merging Galaxy Clusters
Multi-band photometric and multi-object spectroscopic surveys of merging galaxy clusters allow for the characterization of the distributions of constituent dark matter and galaxy populations,
Deep Chandra study of the truncated cool core of the Ophiuchus cluster
We present the results of a deep (280 ks) Chandra observation of the Ophiuchus cluster, the second-brightest galaxy cluster in the X-ray sky. The cluster hosts a truncated cool core, with a
Deep Very Large Array Observations of the Merging Cluster CIZA J2242.8+5301: Continuum and Spectral Imaging
Despite progress in understanding radio relics, there are still open questions regarding the underlying particle acceleration mechanisms. In this paper we present deep 1--4 GHz VLA observations of


On the Connection Between Giant Radio Halos and Cluster Mergers
The frequently observed association between giant radio halos (RHs) and merging galaxy clusters has driven present theoretical models of non-thermal emission from galaxy clusters, which are based on
Diffuse radio emission in MACS J1752.0+4440
We report the discovery of large-scale diffuse radio emission in the galaxy cluster MACS J1752.0+4440 (z = 0.366). Using Westerbork Synthesis Radio Telescope (WSRT) observations we find that the
A search for steep spectrum radio relics and halos with the GMRT
Context. Diffuse radio emission, in the form of radio halos and relics, traces regions in clusters with shocks or turbulence, probably produced by cluster mergers. The shocks and turbulence are
On the formation of cluster radio relics
ABSTRA C T In several merging clusters of galaxies so-called cluster radio relics have been observed. These are extended radio sources which do not seem to be associated with any radio galaxies. Two
Four Extreme Relic Radio Sources in Clusters of Galaxies
We describe the results of the highest-resolution radio observations yet made of four relic radio sources in the Abell clusters A13, A85, A133, and A4038. Our Very Large Array images at 1.4 GHz with
Rise and fall of radio haloes in simulated merging galaxy clusters
We present the first high resolution MHD simulation of cosmic-ray electron reacceleration by turbulence in cluster mergers. We use an idealised model for cluster mergers, combined with a numerical
Many galaxy clusters host megaparsec-scale radio halos, generated by ultrarelativistic electrons in the magnetized intracluster medium. Correlations between the synchrotron power of radio halos and
Bow Shock and Radio Halo in the Merging Cluster A520
Chandra observations of the merging galaxy cluster A520 reveal a prominent bow shock with M = 2.1. This is only the second clear example of a substantially supersonic merger shock front in clusters.
Reviving fossil radio plasma in clusters of galaxies by adiabatic compression in environmental shock waves
We give for a plasma with a history of several expansion and contraction phases an analytical model of the evolution of a contained relativistic electron population under synchrotron, inverse Compton
A new double radio relic in PSZ1 G096.89+24.17 and a radio relic mass-luminosity relation
Radio relics are diffuse synchrotron sources in galaxy clusters that are believed to trace large-scale shock waves. We have discovered a new double radio relic system in PSZ1 G096.89+24.17 (z=0.3)
