Field Flux Picture with Generalized Gauss's law of Gravity for Galactic Disks

[ Oral ]

Te Chun Wang

It is shown first that a gravitational field flux distribution picture within the framework of generalized Gauss's law of Gravity can be used to display the flat rotation curve and Baryonic Tully Fisher Relation of disk galaxies. The flat rotation curve is attributed to an anisotropic cylindrical distribution of the gravitational field flux. The Baryonic Tully Fisher Relation is interpreted as a Gaussian disk thickness approaching twice the radius of a Gaussian sphere with a critical field (10^-10 m/s^2) on the surface. The extension of this scenariao to larger structures including galaxy cluster and cosmic web is discussed.
