Universality of gravitational radiation from magnetar magnetospheres
Arthur G. Suvorov, Petros Stefanou, José A. Pons
The intense magnetic fields inferred from magnetars suggest they may be strong gravitational-wave emitters. Although emissions due to hydromagnetic deformations are more promising…
General-relativistic magnetar magnetospheres in 3D with physics-informed neural networks
Petros Stefanou, Arthur G. Suvorov, José A. Pons
Magnetar phenomena are likely intertwined with the location and structure of magnetospheric currents. General-relativistic effects are important in shaping the force-free equilibri…
Magnetar field dynamics shaped by chiral anomalies and helicity
Clara Dehman, José A. Pons
The chiral magnetic effect (CME) -- a macroscopic manifestation of the quantum chiral anomaly -- induces currents along magnetic field lines, facilitating mutual conversion between…
Revealing the nature of long-period transients with space-based gravitational-wave interferometers
Arthur G. Suvorov, Clara Dehman, José A. Pons
A few members of the recently discovered class of long-period transients have been identified as binaries with white-dwarf primaries. In most cases, however, electromagnetic data a…
Magnetar structure in non-linear electrodynamics with mixed poloidal-toroidal fields
Arthur G. Suvorov, José A. Pons
Magnetars have inferred polar field strengths in excess of the Schwinger limit, where non-linear electromagnetic effects can be significant. Their internal fields may be even stron…
