Influence of Extragalactic Magnetic Fields on Extragalactic Cascade Gamma-Ray Emission
Universe, 2022 We discuss the influence of extragalactic magnetic fields on the intensity of gamma-ray emission produced in electromagnetic cascades from ultra-high energy cosmic rays propagating in extragalactic space.

Constraints on UHECR Sources and Extragalactic Magnetic Fields from Directional Anisotropies [PDF]
The Astrophysical JournalA dipole anisotropy in ultra–high-energy cosmic ray (UHECR) arrival directions, of extragalactic origin, is now firmly established at energies E > 8 EeV.

UHECR anisotropy and extragalactic magnetic fields with the Telescope Array [PDF]
EPJ Web of Conferences, 2023 We study the energy-dependent distribution of ultra-high energy cosmic ray arrival directions with respect to luminous matter in the local Universe. We use a specially designed test statistic (TS) that is robust to uncertainties of the galactic magnetic ...

Magnetic fields and UHECR propagation [PDF]
EPJ Web of Conferences, 2023 I review the main observational tools used to detect and measure magnetic fields in the interstellar medium of our Galaxy (considering both the Galactic disk and the Galactic halo), in the interstellar medium of external galaxies, and in the ...

The Astrophysical Journal Letters, 2023 Faraday rotation measures (RMs) of fast radio bursts (FRBs) offer the prospect of directly measuring extragalactic magnetic fields. We present an analysis of the RMs of 10 as yet nonrepeating FRBs detected and localized to host galaxies with robust ...

Cosmic Rays in Galactic and Extragalactic Magnetic Fields [PDF]
Space Science Reviews, 2011 We briefly review sources of cosmic rays, their composition and spectra as well as their propagation in the galactic and extragalactic magnetic fields, both regular and fluctuating. A special attention is paid to the recent results of the X-ray and gamma-ray observations that shed light on the origin of the galactic cosmic rays and the challenging ...

A Wideband Polarization Observation of Hydra A with the Jansky Very Large Array
The Astrophysical Journal, 2023 We present the results of a wideband high-resolution polarization study of Hydra A, one of the most luminous FR I radio galaxies known and among the most well studied. The radio emission from this source displays extremely large Faraday rotation measures

New Limits on Extragalactic Magnetic Fields from Rotation Measures [PDF]
Physical Review Letters, 2016 We take advantage of the wealth of rotation measures data contained in the NRAO VLA Sky Survey catalogue to derive new, statistically robust, upper limits on the strength of extragalactic magnetic fields. We simulate the extragalactic magnetic field contribution to the rotation measures for a given field strength and correlation length, by assuming ...
