The Sleeping Monster: NuSTAR observations of SGR 1806-20, 11 years after the Giant Flare

George Younes, Matthew G. Baring, Chryssa Kouveliotou +5

We report the analysis of 5 NuSTAR observations of SGR 1806-20 spread over a year from April 2015 to April 2016, more than 11 years following its Giant Flare (GF) of 2004. The sour…

Resonant Inverse Compton Scattering Spectra from Highly-magnetized Neutron Stars

Zorawar Wadiasingh, Matthew G. Baring, Peter L. Gonthier +1

Hard, non-thermal, persistent pulsed X-ray emission extending between 10 keV and keV has been observed in nearly ten magnetars. For inner-magnetospheric models of such e…

X-ray Synchrotron Polarization from Turbulent Plasmas in Supernova Remnants

Matthew G. Baring

As supernova remnants (SNRs) age, they become efficient cosmic ray accelerators at their outer shell shocks. The current paradigm for shock acceleration theory favors turbulent fie…

Hard X-ray Quiescent Emission in Magnetars via Resonant Compton Upscattering

M. G. Baring, Z. Wadiasingh, P. L. Gonthier +1

Non-thermal quiescent X-ray emission extending between 10 keV and around 150 keV has been seen in about 10 magnetars by RXTE, INTEGRAL, Suzaku, NuSTAR and Fermi-GBM. For inner magn…

Constraining Relativistic Bow Shock Properties in Rotation-Powered Millisecond Pulsar Binaries

Zorawar Wadiasingh, Alice K. Harding, Christo Venter +2

Multiwavelength followup of unidentified Fermi sources has vastly expanded the number of known galactic-field "black widow" and "redback" millisecond pulsar binaries. Focusing on t…

Scaling of Relativistic Shear Flows with Bulk Lorentz Factor

Edison Liang, Wen Fu, Markus Boettcher +1

We compare Particle-in-Cell simulation results of relativistic electron-ion shear flows with different bulk Lorentz factors, and discuss their implications for spine-sheath models…

X-ray and radio observations of the magnetar SGR J1935+2154 during its 2014, 2015, and 2016 outbursts

George Younes, Chryssa Kouveliotou, Amruta Jaodand +10

We analyzed broad-band X-ray and radio data of the magnetar SGR J1935+2154 taken in the aftermath of its 2014, 2015, and 2016 outbursts. The source soft X-ray spectrum <10 keV is w…
