Simulating the LOcal Web (SLOW): VII. Intergalactic magnetic field models for multi-messenger applications

Johannes Stoiber, Klaus Dolag, Francesca Capel +4

Context. The propagation of ultra-high-energy cosmic rays (UHECRs) and ultra-high-energy gamma-rays remains an open question in astroparticle physics, with the intergalactic magnet…

Entity -- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. III: Higher-order shape functions & generalized field stencils

Ludwig M. Böss, Arno Vanthieghem, Hayk Hakobyan +2

Modern particle-in-cell (PIC) codes have become an integral tool in plasma astrophysics. As most plasma phenomena grow from initially small instabilities, it is important to ensure…

Single- and double-headed odd radio circles in the LOFAR surveys

F. De Gasperin, M. Brüggen, T. Pasini +7

Deep radio surveys are now producing catalogs with millions of radio sources. Radio sources can have complex morphologies that depend on both the production mechanisms and the loca…

Cosmological Zoom-In Simulation of Odd Radio Circles as Merger-Driven Shocks in Galaxy Groups

Anna Ivleva, Ludwig M. Böss, Klaus Dolag +2

Odd Radio Circles (ORCs) are a new class of distinct radio objects that has recently been discovered. The origin of these features is yet unclear because their peculiar properties…

Entity -- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. I: Curvilinear Special Relativistic Module

Hayk Hakobyan, Ludwig M. Böss, Yangyang Cai +8

Entity is a new-generation, fully open-source particle-in-cell (PIC) code developed to overcome key limitations in astrophysical plasma modeling, particularly the extreme separatio…

Magnetic Fields in the Shapley Supercluster Core with POSSUM: Challenging Model Predictions

D. Alonso-López, S. P. O'Sullivan, A. Bonafede +18

Faraday Rotation Measure (RM) Grids provide a sensitive means to trace magnetized plasma across a wide range of cosmic environments. We study the RM signal from the Shapley Supercl…
