The effect of an offset polar cap dipolar magnetic field on the modeling of the Vela pulsar's γ-ray light curves
(IOP Publishing, 2016)We performed geometric pulsar light curve modeling using static, retarded vacuum, and offset polar cap (PC) dipole B-fields (the latter is characterized by a parameter epsilon), in conjunction with standard two-pole caustic ... -
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 ... -
Pressure balance and intrabinary shock stability in rotation-powered-state redback and transitional millisecond pulsar binary systems
(IOP Publishing, 2018)A number of low-mass millisecond pulsar (MSP) binaries in their rotation-powered state exhibit double-peaked X-ray orbital modulation centered at inferior pulsar conjunction. This state, which has been known to persist for ... -
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 ... -
Whole Earth Telescope discovery of a strongly distorted quadrupole pulsation in the largest amplitude rapidly oscillating Ap star
(Oxford Univ Press, 2018)We present a new analysis of the rapidly oscillating Ap (roAp) star, 2MASS J19400781 − 4420093 (J1940; V = 13.1). The star was discovered using SuperWASP broad-band photometry to have a frequency of 176.39 d−1 (2041.55 μHz; ...
