Deficient Reasoning for Dark Matter in Galaxies
James Q. Feng, C. F. Gallo
Astronomers have been using the measured luminosity to estimate the {\em luminous mass} of stars, based on empirically established mass-to-light ratio which seems to be only applic…
Mass distribution in rotating thin-disk galaxies according to Newtonian dynamics
James Q. Feng, C. F. Gallo
An accurate computational method is presented to determine the mass distribution in a rotating thin-disk galaxy from given rotation curve by applying Newtonian dynamics for an axis…
Modeling the Newtonian Dynamics for Rotation Curve Analysis of Thin-Disk Galaxies
James Q. Feng, C. F. Gallo
We present an efficient, robust computational method for modeling the Newtonian dynamics for rotation curve analysis of thin-disk galaxies. For a disk galaxy with a typical flat ro…
Rotating thin-disk galaxies through the eyes of Newton
James Q. Feng, C. F. Gallo
By numerically solving the mass distribution in a rotating disk based on Newton's laws of motion and gravitation, we demonstrate that the observed flat rotation curves for most spi…
Galactic Rotation Described with Bulge+Disk Gravitational Models
C. F. Gallo, James Q. Feng
Observations reveal that mature spiral galaxies consist of stars, gases and plasma approximately distributed in a thin disk of circular shape, usually with a central bulge. The rot…
Galactic Rotation Described with Various Thin-Disk Gravitational Models
James Q. Feng, C. F. Gallo
For mature spiral galaxies, the rotation velocities quickly increase from the galactic center and achieve a constant velocity from the core to the periphery. This dynamic behavior…
