Bridging the mass gap: Diffuse radio emission in GAMA galaxy groups using EMU and DINGO survey data
Sai Wagh, Tessa Vernstrom, Luke J. M. Davies +11
Diffuse radio emission provides a powerful probe of non-thermal processes in the large-scale structure, yet its properties in galaxy groups remain poorly constrained. Using deep 94…
The Large-Scale Structure of the Universe through the SKA lenses
Virginia Cuciti, Surajit Paul, Viral Parekh +11
The large-scale distribution of galaxies in the Universe forms an intricate, interconnected network known as the cosmic web. Cosmological simulations within the standard Lambda-CDM…
Isochrones in primordial magnetic field evolution
Axel Brandenburg, Mattia Cielo, Oksana Iarygina +1
In the early universe, a primordial magnetic field undergoes a turbulent decay while its length scale increases due to an inverse cascade. The size of the largest processed eddy sc…
The Impact of the Magnetised Cosmic Web on Ultra High Energy Cosmic Ray Propagation
Allegra Firinu, Franco Vazza, Carmelo Evoli
The origin of ultra-high-energy cosmic rays (UHECRs) remains an open question. Extragalactic magnetic fields can modify their propagation and, at sufficiently low energies, suppres…
A perfect power-law spectrum even at highest frequencies: The Toothbrush relic
K. Rajpurohit, F. Vazza, M. Hoeft +12
Radio relics trace shock fronts generated in the intracluster medium (ICM) during cluster mergers. The particle acceleration mechanism at the shock fronts is not yet completely und…
The Complexity and Information Content of Simulated Universes
Franco Vazza
The emergence of a complex, large-scale organisation of cosmic matter into the Cosmic Web is a beautiful exemplification of how complexity can be produced by simple initial conditi…
New constraints on the magnetization of the cosmic web using LOFAR Faraday rotation observations
S. P. O'Sullivan, M. Brüggen, F. Vazza +11
Measuring the properties of extragalactic magnetic fields through the effect of Faraday rotation provides a means to understand the origin and evolution of cosmic magnetism. Here w…
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…
Unveiling the Galaxy Cluster - Cosmic Web Connection with X-ray observations in the Next Decade
Stephen A. Walker, Daisuke Nagai, A. Simionescu +35
In recent years, the outskirts of galaxy clusters have emerged as one of the new frontiers and unique laboratories for studying the growth of large scale structure in the universe.…
The turbulent pressure support in galaxy clusters revisited
F. Vazza, M. Angelinelli, T. W. Jones +4
Due to their late formation in cosmic history, clusters of galaxies are not fully in hydrostatic equilibrium and the gravitational pull of their mass at a given radius is expected…
LOFAR discovery of radio emission in MACSJ0717.53745
A. Bonafede, M. Brüggen, D. Rafferty +16
We present results from LOFAR and GMRT observations of the galaxy cluster MACSJ0717.53745. The cluster is undergoing a violent merger involving at least four sub-clusters, a…
Simulations of extragalactic magnetic fields and of their observables
F. Vazza, M. Brüggen, C. Gheller +3
The origin of extragalactic magnetic fields is still poorly understood. Based on a dedicated suite of cosmological magneto-hydrodynamical simulations with the ENZO code we have per…
On the complexity and the information content of cosmic structures
Franco Vazza
The emergence of cosmic structure is commonly considered one of the most complex phenomena in Nature. However, this complexity has never been defined nor measured in a quantitative…
Discovery of radio halos and double-relics in distant MACS galaxy clusters: clues to the efficiency of particle acceleration
A. Bonafede, M Brueggen, R. van Weeren +6
We have performed 323 MHz observations with the Giant Metrewave Radio Telescope of the most promising candidates selected from the MACS catalog. The aim of the work is to extend ou…
Turbulent Motions and Shocks Waves in Galaxy Clusters simulated with AMR
F. Vazza, G. Brunetti, A. Kritsuk +3
We have implemented an Adaptive Mesh Refinement criterion explicitly designed to increase spatial resolution around discontinuities in the velocity field in ENZO cosmological simul…
