Strong Polarization Signatures from Magnetically Stabilized Luminous Thin Accretion Disks
P. Chris Fragile, Peter Anninos, Madeline Breiling +2
We utilize the Monte Carlo radiation transport capabilities of Cosmos++ to explore the polarization and Faraday rotation of radiation emitted from a set of general relativistic rad…
r-Process nucleosynthesis from hyperaccreting neutron stars in common envelopes
Peter Anninos, Matthew Portman, Scott Carmichael +2
We investigate nuclear reactions and feedback in hyperaccreting neutron star environments, considering accretion rates in the range 0.3 - yr, typical…
Stability and convergence of nuclear detonations in white dwarf collisions
Peter Anninos, David Cruz-Lopez, Brighten Jiang +1
We investigate the numerical stability of thermonuclear detonations in 1D accelerated reactive shocks and 2D binary collisions of equal mass, magnetized and unmagnetized white dwar…
X-ray Spectra from General Relativistic RMHD Simulations of Thin Disks
Nathaniel Roth, Peter Anninos, P. Chris Fragile +1
We compare X-ray emission from several general relativistic, multi-frequency, radiation magnetohydrodynamic simulations of thin black hole accretion disks with different accretion…
Graviton-Photon Oscillations in an Expanding Universe
Peter Anninos, Tony Rothman, Andrea Palessandro
Through the Gertsenshtein effect, the presence of a large external B-field may allow photons and gravitons to mix in a way that resembles neutrino oscillations and is even more sim…
Multi-Frequency General Relativistic Radiation-Magnetohydrodynamic Simulations of Thin Disks
P. Chris Fragile, Peter Anninos, Nathaniel Roth +1
We present a set of six general relativistic, multi-frequency, radiation magnetohydrodynamic simulations of thin accretion disks with different target mass accretion rates around b…
