WebMar 11, 2015 · This ladder can be calibrated at z ∼ 0 using local determinations of the Hubble constant or at high redshift using the CMB determination of the sound horizon at radiation drag. The first approach is the classic (direct) cosmic distance ladder calibration while we refer to the second as an inverse cosmic distance ladder.

A direct distance measurement of an astronomical object is possible only for those objects that are "close enough" (within about a thousand … See more At the base of the ladder are fundamental distance measurements, in which distances are determined directly, with no physical assumptions about the nature of the object in question. The precise measurement of … See more Gravitational waves originating from the inspiral phase of compact binary systems, such as neutron stars or black holes, have the useful property that energy emitted as gravitational … See more With few exceptions, distances based on direct measurements are available only out to about a thousand parsecs, which is a modest portion of our own Galaxy. For distances beyond that, measures depend upon physical assumptions, that is, the assertion that one … See more A succession of distance indicators, which is the distance ladder, is needed for determining distances to other galaxies. The reason is that objects bright enough to be recognized … See more Almost all astronomical objects used as physical distance indicators belong to a class that has a known brightness. By comparing this known luminosity to an object's observed brightness, the distance to the object can be computed using the inverse-square law. … See more Another class of physical distance indicator is the standard ruler.
