Monitoring the power spectrum of magnetic field fluctuations across the simulated intracluster medium
T. Bartalesi, F. Vazza, S. Ettori +2
Thanks to the current and forthcoming radio interferometers, Faraday rotation measure maps extend out to the outskirts of galaxy clusters. Interpreted through models of the magneti…
ICM-SHOX III. The case of MACS J0018.5+1626, a radio relic that looks like a radio halo?
P. Domínguez-Fernández, J. A. ZuHone, E. M. Silich +9
We present the first detailed numerical modeling of the radio emission from MACS J0018.5+1626 as part of the Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Op…
Jet interaction with galaxy cluster mergers
Paola Domínguez-Fernández, John ZuHone, Rainer Weinberger +4
AGN bubbles in cool-core galaxy clusters are believed to facilitate the transport of cosmic ray electrons (CRe) throughout the cluster. Recent radio observations are revealing comp…
Intergalactic medium rotation measure of primordial magnetic fields
Salome Mtchedlidze, Paola Domínguez-Fernández, Xiaolong Du +5
The Faraday rotation effect, quantified by the Rotation Measure (RM), is a powerful probe of the large-scale magnetization of the Universe - tracing magnetic fields not only on gal…
Radio surface fluctuations in radio relics
Paola Domínguez-Fernández, Dongsu Ryu, Hyesung Kang
Recent observations have revealed detailed structures of radio relics in a wide range of frequencies. In this work, we perform three-dimensional magnetohydrodynamical simulations o…
Weak-Lensing Analysis of the Complex Cluster Merger Abell 746 with Subaru/Hyper Suprime-Cam
Kim HyeongHan, Hyejeon Cho, M. James Jee +15
The galaxy cluster Abell 746 (A746; =0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intr…
On the Polarisation of Radio Relics
Matthias Hoeft, Kamlesh Rajpurohit, Denis Wittor +2
Radio relics are extended radio emission features which trace shock waves in the periphery of galaxy clusters originating from cluster mergers. Some radio relics show a highly pola…
Turbulent magnetic fields in the merging galaxy cluster MACS J0717.5+3745: polarization analysis
K. Rajpurohit, M. Hoeft, D. Wittor +20
We present wideband polarimetric observations, obtained with the Karl G. Jansky Very Large Array (VLA), of the merging galaxy cluster MACS J0717.5+3745, which hosts one of the most…
Accretion of a Vlasov gas on to a black hole from a sphere of finite radius and the role of angular momentum
Aldo Gamboa, Carlos Gabarrete, Paola Domínguez-Fernández +2
The accretion of a spherically symmetric, collisionless kinetic gas cloud on to a Schwarzschild black hole is analysed. Whereas previous studies have treated this problem by specif…
Exploring the spectral properties of radio relics I: Integrated spectral index and Mach number
Denis Wittor, Stefano Ettori, Franco Vazza +3
Radio relics are the manifestation of electrons presumably being shock (re-)accelerated to high energies in the outskirts of galaxy clusters. However, estimates of the shocks' stre…
Dissecting nonthermal emission in the complex multiple-merger galaxy cluster Abell 2744: Radio and X-ray analysis
K. Rajpurohit, F. Vazza, R. J. van Weeren +14
We present the first deep low frequency radio observations of the massive and highly disturbed galaxy cluster Abell 2744 using the upgraded Giant Metrewave Radio Telescope (uGMRT).…
Polarisation of Radio Relics in Galaxy Clusters
Denis Wittor, Matthias Hoeft, Franco Vazza +2
Radio emission in the form of giant radio relics is observed at the periphery of galaxy clusters. This non-thermal emission is an important tracer for cosmic-ray electrons and intr…
A Song of Shocks and Dynamo: Numerical Studies of a Galaxy Cluster Merger in the HIMAG Project
Denis Wittor, Paola Domínguez-Fernández, Franco Vazza +1
With ENZO simulations run on the Jülich supercomputers, we have investigated the evolution of magnetic fields in the largest cosmic structures (namely galaxy clusters and filaments…
Dynamical evolution of magnetic fields in the intracluster medium
Paola Domínguez-Fernández, Franco Vazza, Marcus Brüggen +1
We investigate the evolution of magnetic fields in galaxy clusters starting from constant primordial fields using highly resolved () cosmological MHD simulation…
The challenge of detecting intracluster filaments with Faraday Rotation
Nicola Locatelli, Franco Vazza, Paola Domínguez-Fernández
The detection of filaments in the cosmic web will be crucial to distinguish between the possible magnetogenesis scenarios and future large polarization surveys will be able to shed…
