Magnetic, thermal and rotational evolution of isolated neutron stars
José A. Pons, Clara Dehman, Daniele Viganò
The strong magnetic fields of neutron stars are closely linked to their observed thermal, spectral, and timing properties, such as the distribution of spin periods and their deriva…
Late-blooming magnetars: awakening as long period transients after a dormant cooling epoch
Arthur G. Suvorov, Clara Dehman, José A. Pons
Long-period transients are an elusive class of compact objects uncovered by radio surveys. While magnetars are a leading candidate for those sources that appear isolated, several o…
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…
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 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…
