Extended VHE γ-ray emission towards SGR1806-20, LBV 1806-20, and stellar cluster Cl 1806-20
(EDP Sciences, 2018)Using the High Energy Spectroscopic System (H.E.S.S.) telescopes we have discovered a steady and extended very high-energy (VHE) γ-ray source towards the luminous blue variable candidate LBV 1806−20, massive stellar cluster ... -
Opacities for photon splitting and pair creation in neutron star magnetospheres
(Oxford Univ Press, 2019)Over the last four decades, persistent and flaring emission of magnetars observed by various telescopes has provided us with a suite of light curves and spectra in soft and hard X-rays, with no emission yet detected above ... -
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 ... -
Resonant inverse Compton scattering spectra from highly magnetized neutron stars
(IOP Publishing, 2018)Hard, nonthermal, persistent pulsed X-ray emission extending between 10 and ~150 keV has been observed in nearly 10 magnetars. For inner-magnetospheric models of such emission, resonant inverse Compton scattering of soft ... -
Revival of the Magnetar PSR J1622-4950: observations with MeerKAT, Parkes, XMM-Newton, Swift, Chandra, and NuSTAR
(IOP Publishing, 2018)New radio (MeerKAT and Parkes) and X-ray (XMM-Newton, Swift, Chandra, and NuSTAR) observations of PSR J1622–4950 indicate that the magnetar, in a quiescent state since at least early 2015, reactivated between 2017 March ...
