Kerr Black Holes are Not Unique to General Relativity
Dimitrios Psaltis, Delphine Perrodin, Keith R. Dienes +1
Considerable attention has recently focused on gravity theories obtained by extending general relativity with additional scalar, vector, or tensor degrees of freedom. In this paper…
Constraining Radiatively Inefficient Accretion Flows with Polarization
D. R. Ballantyne, F. Ozel, D. Psaltis
The low-luminosity black hole Sgr A* provides a testbed for models of Radiatively Inefficient Accretion Flows (RIAFs). Recent sub-millimeter linear polarization measurements of Sgr…
Angular Momentum Transport in Accretion Disks: Scaling Laws in MRI-driven Turbulence
Martin E. Pessah, Chi-kwan Chan, Dimitrios Psaltis
We present a scaling law that predicts the values of the stresses obtained in numerical simulations of saturated MRI-driven turbulence in non-stratified shearing boxes. It relates…
Testing General Metric Theories of Gravity with Bursting Neutron Stars
Dimitrios Psaltis
I show that several observable properties of bursting neutron stars in metric theories of gravity can be calculated using only conservation laws, Killing symmetries, and the Einste…
