Shear dynamo problem: Quasilinear kinematic theory
S. Sridhar, Kandaswamy Subramanian
Large-scale dynamo action due to turbulence in the presence of a linear shear flow is studied. Our treatment is quasilinear and kinematic but is non perturbative in the shear stren…
Imbalanced Strong MHD Turbulence
Yoram Lithwick, Peter Goldreich, S. Sridhar
We present a phenomenological model of imbalanced MHD turbulence in an incompressible magnetofluid. The steady-state cascades, of waves traveling in opposite directions along the m…
Folded Fields as the Source of Extreme Radio-Wave Scattering in the Galactic Center
Peter Goldreich, S. Sridhar
A strong case has been made that radio waves from sources within about half a degree of the Galactic Center undergo extreme diffractive scattering. However, problems arise when sta…
Recovery of transverse velocities of steadily rotating patterns in flat galaxies
S. Sridhar, Niranjan Sambhus
The transverse velocities of steadily rotating, non--axisymmetric patterns in flat galaxies may be determined by a purely kinematical method, using two dimensional maps of a tracer…
Dynamical Modeling of the Stellar Nucleus of M31
Niranjan Sambhus, S. Sridhar
We present stellar dynamical models of the lopsided, double-peaked nucleus of M31, derived from Hubble Space Telescope (HST) photometry. A Schwarzscild-type method, in conjunction…
Stellar orbits in triaxial clusters around black holes in galactic nuclei
Niranjan Sambhus, S. Sridhar
We investigate the orbital structure of a model triaxial star cluster, centered around a supermassive black hole (BH), appropriate to galactic nuclei. Sridhar and Touma (1999) prov…
