Special and General Relativistic Effects in Galactic Rotation Curves
Alan Cooney, Dimitrios Psaltis, Dennis Zaritsky
The observed flat rotation curves of galaxies require either the presence of dark matter in Newtonian gravitational potentials or a significant modification to the theory of gravit…
Modeling Collisional Cascades In Debris Disks: The Numerical Method
Andras Gaspar, Dimitrios Psaltis, Feryal Ozel +2
We develop a new numerical algorithm to model collisional cascades in debris disks. Because of the large dynamical range in particle masses, we solve the integro-differential equat…
Neutron Stars in f(R) Gravity with Perturbative Constraints
Alan Cooney, Simon DeDeo, Dimitrios Psaltis
We study the structure of neutron stars in f(R) gravity theories with perturbative constraints. We derive the modified Tolman-Oppenheimer-Volkov equations and solve them for a poly…
Gravity with Perturbative Constraints: Dark Energy Without New Degrees of Freedom
Alan Cooney, Simon DeDeo, Dimitrios Psaltis
Major observational efforts in the coming decade are designed to probe the equation of state of dark energy. Measuring a deviation of the equation-of-state parameter w from -1 woul…
