    • The fast radio burst luminosity function and death line in the low-twist Magnetar Model 

      Wadiasingh, Zorawar; Beniamini, Paz; Timokhin, Andrey; Baring, Matthew G.; Van der Horst, Alexander J. (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 

      Wadiasingh, Zorawar; Chirenti, Cecilia (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 ...
    • A NICER view of spectral and profile evolution for three x-ray-emitting millisecond pulsars 

      Rowan, Dominick M.; Venter, Christo; Ghazi, Zaynab; Lugo, Lauren; Spano, Elizabeth (IOP, 2020)
      We present two years of Neutron star Interior Composition Explorer (NICER) X-ray observations of three energetic rotation-powered millisecond pulsars (MSPs): PSRs B1937+21, B1821−24, and J0218+4232. We fit Gaussians and ...
    • Spatially-dependent multi-wavelength modeling of pulsar wind nebulae 

      Van Rensburg, Carlo (North-West University (South Africa), Potchefstroom Campus, 2020)
      The next era of ground-based Cherenkov telescope development will see a great increase in both quantity and quality of γ-ray morphological data. This initiated the development of a spatio-temporal leptonic transport code ...
    • X-ray polarimetry with the Polarization Spectroscopic Telescope Array (PolSTAR) 

      Krawczynski, Henric S.; Böttcher, Markus; Stern, Daniel; Harrison, Fiona A.; Kislat, Fabian F. (Elsevier, 2016)
      This paper describes the Polarization Spectroscopic Telescope Array (PolSTAR), a mission proposed to NASA’s 2014 Small Explorer (SMEX) announcement of opportunity. PolSTAR measures the linear polarization of 3–50 keV ...
