The MIni-Halos in MIni-Clusters (MIMIC) project: New insights into the origin of mini-halos from a LOFAR, uGMRT, and MeerKAT study of diffuse radio emission in Abell 496 and ZwCl 235
F. Ubertosi, S. Giacintucci, A. Botteon +18
We aim at investigating the presence of diffuse radio emission in low-mass (M M), relaxed galaxy clusters. We present a pilot study for the MIMI…
Investigating the magnetic field in the inter-cluster filament between Abell 3667 and Abell 3651 with POSSUM
C. Stuardi, S. P. O'Sullivan, L. Rudnick +19
[Abridged abstract] The objective of this study is to measure the magnetic field within the prominent inter-cluster filament recently detected in X-rays by the extended ROentgen Su…
Detection of magnetic fields in superclusters of galaxies
G. V. Pignataro, S. P. O'Sullivan, A. Bonafede +3
Magnetic fields in large scale structure filaments beyond galaxy clusters remain poorly understood. Superclusters offer a unique setting to study these low density environments, wh…
Mind the Gap between A2061 and A2067: Unveiling new diffuse large-scale radio emission
G. V. Pignataro, A. Bonafede, G. Bernardi +11
The clusters Abell 2061 and Abell 2067 in the Corona Borealis supercluster have been studied at different radio frequencies and are both known to host diffuse radio emission. The a…
Abell 0399-Abell 0401 radio bridge spectral index: the first multifrequency detection
G. V. Pignataro, A. Bonafede, G. Bernardi +12
Recent low-frequency radio observations at 140 MHz discovered a 3 Mpc-long bridge of diffuse emission connecting the galaxy clusters Abell 0399 and Abell 0401. We present follow-up…
Probing diffuse radio emission in bridges between galaxy clusters with uGMRT
G. V. Pignataro, A. Bonafede, G. Bernardi +3
The main purpose of this work is to investigate the properties of the non-thermal emission in the interacting clusters pairs Abell 0399-Abell 0401 and Abell 21-PSZ2 G114.9, found i…
The self-confinement of electrons and positrons from dark matter
Marco Regis, Michael Korsmeier, Gianni Bernardi +3
Radiative emissions from electrons and positrons generated by dark matter (DM) annihilation or decay are one of the most investigated signals in indirect searches of WIMPs. Ideal t…
Diffuse radio emission from non-Planck galaxy clusters in the LoTSS-DR2 fields
D. N. Hoang, M. Brüggen, A. Botteon +17
The presence of large-scale magnetic fields and ultra-relativistic electrons in the intra-cluster medium (ICM) is confirmed through the detection of diffuse radio synchrotron sourc…
The probability of galaxy-galaxy strong lensing events in hydrodynamical simulations of galaxy clusters
Massimo Meneghetti, Antonio Ragagnin, Stefano Borgani +27
Meneghetti et al. (2020) recently reported an excess of galaxy-galaxy strong lensing (GGSL) in galaxy clusters compared to expectations from the LCDM cosmological model. Theoretica…
A strong lensing model of the galaxy cluster PSZ1 G311.65-18.48
G. V. Pignataro, P. Bergamini, M. Meneghetti +10
We present a strong lensing analysis of the galaxy cluster PSZ1 G311.65-18.48 (z=0.443) using multi-band observations with Hubble Space Telescope, complemented with VLT/MUSE spectr…
High star cluster formation efficiency in the strongly lensed Sunburst Lyman-continuum galaxy at z=2.37
E. Vanzella, M. Castellano, P. Bergamini +16
We investigate the strongly lensed (μx10-100) Lyman continuum (LyC) galaxy, dubbed Sunburst, at z=2.37, taking advantage of a new accurate model of the lens. A characterization of…
