Electron-Capture and Low-Mass Iron-Core-Collapse Supernovae: New Neutrino-Radiation-Hydrodynamics Simulations
David Radice, Adam Burrows, David Vartanyan +2
We present new 1D (spherical) and 2D (axisymmetric) simulations of electron-capture (EC) and low-mass iron-core-collapse supernovae (SN). We consider six progenitor models: the ECS…
The Galactic Center Weather Forecast
Monika Moscibrodzka, Hotaka Shiokawa, Charles F. Gammie +1
In accretion-based models for Sgr A* the X-ray, infrared, and millimeter emission arise in a hot, geometrically thick accretion flow close to the black hole. The spectrum and size…
Near-Infrared and X-ray Quasi-Periodic Oscillations in Numerical Models of Sgr A*
Joshua C. Dolence, Charles F. Gammie, Hotaka Shiokawa +1
We report transient quasi-periodic oscillations (QPOs) on minute timescales in relativistic, radiative models of the galactic center source Sgr A*. The QPOs result from nonaxisymme…
Numerical Models of Sgr A*
M. Moscibrodzka, C. F. Gammie, J. Dolence +2
We review results from general relativistic axisymmetric magnetohydrodynamic simulations of accretion in Sgr A*. We use general relativistic radiative transfer methods and to produ…
