Constraining relativistic bow shock properties in rotation-powered millisecond pulsar binaries
(AAS, 2017)Multiwavelength follow-up of unidentified Fermi sources has vastly expanded the number of known galactic-field "black widow" and "redback" millisecond pulsar binaries. Focusing on their rotation-powered state, we interpret ... -
Constraining the emission geometry and mass of the white dwarf pulsar AR Sco using the rotating vector model
(IOP Publishing, 2019)We apply the standard radio pulsar rotating vector model to the white dwarf (WD) pulsar AR Sco's optical polarization position angle swings folded at the WD's spin period as obtained by Buckley et al. Owing to the long ... -
The fast radio burst luminosity function and death line in the low-twist Magnetar Model
(IOP, 2020)We explore the burst energy distribution of fast radio bursts (FRBs) in the low-twist magnetar model of Wadiasingh & Timokhin (WT19). Motivated by the power-law fluence distributions of FRB 121102, we propose an elementary ... -
Fast radio burst trains from magnetar oscillations
(IOP Publishing, 2020)Quasi-periodic oscillations inferred during rare magnetar giant flare tails were initially interpreted as torsional oscillations of the neutron star (NS) crust, and have been more recently described as global core+crust ... -
Periodicity in recurrent fast radio bursts and the origin of ultralong period magnetars
(Oxford Univ Press, 2020)The recurrent fast radio burst FRB 180916 was recently shown to exhibit a 16-d period (with possible aliasing) in its bursting activity. Given magnetars as widely considered FRB sources, this period has been attributed to ... -
Repeating fast radio bursts from magnetars with low magnetospheric twist
(IOP Publishing, 2019)We analyze the statistics of pulse arrival times in fast radio burst (FRB) 121102 and demonstrate that they are remarkably similar to statistics of magnetar high-energy short bursts. Motivated by this correspondence, we ...
