New biorthogonal potential--density basis functions
Alireza Rahmati, Mir Abbas Jalali
We use the weighted integral form of spherical Bessel functions, and introduce a new analytical set of complete and biorthogonal potential--density basis functions. The potential a…
Unstable Disk Galaxies. II. the Origin of Growing and Stationary Modes
Mir Abbas Jalali
I decompose the unstable growing modes of stellar disks to their Fourier components and present the physical mechanism of instabilities in the context of resonances. When the equil…
Inferring statistics of planet populations by means of automated microlensing searches
M. Dominik, U. G. Jorgensen, K. Horne +17
(abridged) The study of other worlds is key to understanding our own, and not only provides clues to the origin of our civilization, but also looks into its future. Rather than in…
A New 3D Potential-Density Basis Set
Alireza Rahmati, Mir Abbas Jalali
A set of bi-orthogonal potential-density basis functions is introduced to model the density and its associated gravitational field of three dimensional stellar systems. Radial comp…
f(R) Gravity: From the Pioneer Anomaly to the Cosmic Acceleration
Reza Saffari, Sohrab Rahvar
We use metric formalism in modified gravity to study the dynamics of various systems from the solar system to the cosmological scale. we assume an ansatz for the derivative…
Unstable Disk Galaxies. I. Modal Properties
Mir Abbas Jalali
I utilize the Petrov-Galerkin formulation and develop a new method for solving the unsteady collisionless Boltzmann equation in both the linear and nonlinear regimes. In the first…
