Simulated Rotation Measure Sky from Primordial Magnetic Fields
Salome Mtchedlidze, Franco Vazza, Xiaolong Du +3
Primordial Magnetic Fields (PMFs) -- magnetic fields originating in the early Universe and permeating the cosmological scales today -- can explain the observed microGauss-level mag…
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…
Improved constraints on the Faraday rotation towards eight fast radio bursts using dense grids of polarized radio galaxies
Ayush Pandhi, Bryan M. Gaensler, Ziggy Pleunis +6
We present 2-4 GHz observations of polarized radio galaxies towards eight fast radio bursts (FRBs), producing grids of Faraday rotation measure (RM) sources with sky densities of 9…
LOFAR Deep Fields: Probing the sub-mJy regime of polarized extragalactic sources in ELAIS-N1. II. Analysis
S. Piras, C. Horellou, J. Conway +7
Deep polarization surveys at low radio frequencies are key to cosmic magnetism studies: Larger catalogs of polarized extragalactic sources and increased precision on Faraday rotati…
Intergalactic medium rotation measure of primordial magnetic fields
Salome Mtchedlidze, Paola DomÃnguez-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…
On the nature of LOFAR RMs and new constraints on magnetic fields in cosmic filaments and on magnetogenesis scenarios
E. Carretti, F. Vazza, S. P. O'Sullivan +6
The measurement of magnetic fields in cosmic web filaments can be used to reveal the magnetogenesis of the Universe. In previous work, we produced first estimates of the field stre…
