Spletof the mass-to-light ratio (M/L) with galaxy luminosity. It is now clear that the Faber–Jackson relation is the projection of a thin plane, the Fundamental Plane (FP; … Spletof the M /L ratio is expected to decrease linearly with redshift, and the coefficient depends on K(IMF), qo, and Zform. This equation is valid for qo ~ 0, and high Zform. The equation implies that therate at which M / L ratio decreases is a function of several unknownvariables, and a direct interpretation of the observed decrease of the M /L ...

Splet12. apr. 2024 · The ratio of the mass of an object to its total luminosity. The mass and luminosity are usually measured in terms of solar mass and solar luminosity; hence the mass-to-light ratio of the Sun is 1. Most extragalactic objects have mass-to-light ratios greater than 1, indicating that not all their mass is in the form of visible stars. Spletthe half-mass radius, but the measurement is based on the half-light radius, and we don’t know whether total mass follows the light distribution (in general, it doesn’t). This value of r h is therefore almost certainly too small, resulting in an underestimate of the total mass and mass-to-light ratio.
