Late-time post-merger modeling of a compact binary: effects of relativity, r-process heating, and treatment of transport effects

Milad Haddadi, Matthew D. Duez, Francois Foucart +8

Detectable electromagnetic counterparts to gravitational waves from compact binary mergers can be produced by outflows from the black hole-accretion disk remnant during the first t…

Long-term 3D-MHD Simulations of Black Hole Accretion Disks formed in Neutron Star Mergers

Steven Fahlman, Rodrigo Fernández

We examine the long-term evolution of accretion tori around black hole (BH) remnants of compact object mergers involving at least one neutron star, to better understand their contr…

Probing magnetar emission mechanisms with spectropolarimetry

Ilaria Caiazzo, Denis González-Caniulef, Jeremy Heyl +1

Over the next year, a new era of observations of compact objects in X-ray polarization will commence. Among the key targets for the upcoming Imaging X-ray Polarimetry Explorer miss…

The Role of Magnetic Field Geometry in the Evolution of Neutron Star Merger Accretion Discs

I. M. Christie, A. Lalakos, A. Tchekhovskoy +4

Neutron star mergers are unique laboratories of accretion, ejection, and r-process nucleosynthesis. We used 3D general relativistic magnetohydrodynamic simulations to study the rol…

Stability of a Spherical Accretion Shock with Nuclear Dissociation

Rodrigo Fernández, Christopher Thompson

We examine the stability of a standing shock wave within a spherical accretion flow onto a gravitating star, in the context of core-collapse supernova explosions. Our focus is on t…

Resonant Cyclotron Scattering in Three Dimensions and the Quiescent Non-thermal X-ray Emission of Magnetars

Rodrigo Fernandez, Christopher Thompson

Although the surface of a magnetar is a source of bright thermal X-rays, its spectrum contains substantial non-thermal components. The X-ray emission is pulsed, with pulsed fractio…
