E. S. Battistelli, E. Barbavara, P. de Bernardis +33
Galaxy clusters and surrounding medium, can be studied using X-ray bremsstrahlung emission and Sunyaev Zel'dovich (SZ) effect. Both astrophysical probes, sample the same environmen…
A multishock scenario for the formation of radio relics
David C. Smolinski, Denis Wittor, Franco Vazza +1
Radio relics are giant sources of diffuse synchrotron radio emission in the outskirts of galaxy clusters that are associated with shocks in the intracluster medium. Still, the orig…
Euclid preparation. LII. Forecast impact of super-sample covariance on 3x2pt analysis with Euclid
Euclid Collaboration, D. Sciotti, S. Gouyou Beauchamps +221
Deviations from Gaussianity in the distribution of the fields probed by large-scale structure surveys generate additional terms in the data covariance matrix, increasing the uncert…
Constraints on the magnetic field in the inter-cluster bridge A399-A401
M. Balboni, A. Bonafede, G. Bernardi +7
Galaxy cluster mergers are natural consequences of the structure formation in the Universe. Such events involve a large amount of energy ( erg) dissipated during the…
A three-component giant radio halo: the puzzling case of the galaxy cluster Abell 2142
L. Bruno, A. Botteon, T. Shimwell +16
Turbulence introduced into the intra-cluster medium (ICM) through cluster merger events transfers energy to non-thermal components, and can trigger the formation of diffuse synchro…
A New Galaxy Cluster Merger Capable of Probing Dark Matter: Abell 56
David Wittman, Rodrigo Stancioli, Kyle Finner +3
We report the discovery of a binary galaxy cluster merger via a search of the redMaPPer optical cluster catalog, with a projected separation of 535 kpc between the BCGs. Archival X…
Synchrotron Intensity Gradient Revealing Magnetic Fields in Galaxy Clusters
Yue Hu, C. Stuardi, A. Lazarian +3
Magnetic fields and their dynamical interplay with matter in galaxy clusters contribute to the physical properties and evolution of the intracluster medium. However, the current un…
On the redshift evolution of the baryon and gas fraction in simulated groups and clusters of galaxies
M. Angelinelli, S. Ettori, K. Dolag +2
We study the redshift evolution of the baryon budget in a large set of galaxy clusters from the {\it Magneticum} suite of SPH cosmological simulations. At high redshifts, we obtain…
Investigating the large-scale environment of wide-angle tailed radio galaxies in the local Universe
V. Missaglia, A. Paggi, F. Massaro +7
We present a statistical analysis of the large-scale (up to 2 Mpc) environment of an homogeneous and complete sample, both in radio and optical selection, of wide-angle tailed radi…
Investigating the turbulent hot gas in X-COP galaxy clusters
Simon Dupourqué, Nicolas Clerc, Etienne Pointecouteau +3
Turbulent processes at work in the intracluster medium perturb this environment, displacing gas, and creating local density fluctuations that can be quantified via X-ray surface br…
Optical/X-ray/radio view of Abell 1213: A galaxy cluster with anomalous diffuse radio emission
W. Boschin, M. Girardi, S. De Grandi +5
Context. Abell 1213, a low-richness galaxy system, is known to host an anomalous radio halo detected in data of the VLA. It is an outlier with regard to the relation between the ra…
Weakly interacting massive particle cross section limits from LOFAR observations of dwarf spheroidal galaxies
L. Gajović, F. Welzmüller, V. Heesen +8
Weakly interacting massive particles (WIMPs) can self-annihilate, thus providing us with a way to indirectly detect dark matter (DM). Dwarf spheroidal (dSph) galaxies are excellent…
Polarized accretion shocks from the cosmic web
Tessa Vernstrom, Jennifer West, Franco Vazza +3
On the largest scales, galaxies are pulled together by gravity to form clusters, which are connected by filaments making a web-like pattern. Radio emission is predicted from this c…
