An SKA-Low RM Grid for constraining the origin of cosmic magnetism
Shane P. O'Sullivan, Franco Vazza, Ettore Carretti +2
Understanding the origin and evolution of cosmic magnetic fields is a key science goal for the SKAO. Recent advances in metre-wavelength (m-) Faraday rotation measure (RM) grids…
Magnetic field spreading from stellar and galactic dynamos into the exterior
Axel Brandenburg, Oindrila Ghosh, Franco Vazza +1
The exteriors of stellar and galactic dynamos are usually modeled as current-free potential fields. A more realistic description might instead be that of a force-free magnetic fiel…
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…
Can galactic magnetic fields diffuse into the voids?
Oindrila Ghosh, Axel Brandenburg, Chiara Caprini +2
Cosmic voids are magnetized at the level of at least G on Mpc scales, as implied by blazar observations. We show that an electrically conducting plasma is present in the…
Radio Observations as a Probe of Cosmic Web Magnetism
Ettore Carretti, Franco Vazza
The Universe's magnetogenesis can be investigated with radio observations of cosmic filaments, where the information on the initial magnetic field seeds is expected to be preserved…
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…
Intergalactic magnetism in a gamma-ray beam as a model of Porphyrion
A. Neronov, F. Vazza, A. Brandenburg +1
We estimate the magnetic field in the jets of the recently discovered 7 Mpc long Porphyrion system. We use non-detection of the system in gamma-rays to derive a lower bound on the…
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…
Discovery of Magnetic Fields Along Stacked Cosmic Filaments as Revealed by Radio and X-Ray Emission
Tessa Vernstrom, George Heald, Franco Vazza +5
Diffuse filaments connect galaxy clusters to form the cosmic web. Detecting these filaments could yield information on the magnetic field strength, cosmic ray population and temper…
Magnetism Science with the Square Kilometre Array
George Heald, Sui Ann Mao, Valentina Vacca +41
The Square Kilometre Array (SKA) will answer fundamental questions about the origin, evolution, properties, and influence of magnetic fields throughout the Universe. Magnetic field…
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…
