How is redshift used to measure distance
WebAt high redshift, the angular diameter distance is such that 1 arcsec is on the order of 5 kpc. There is also an angular diameter distance DA12between two objects at redshifts z1and z2, frequently used in gravitational lensing. It is not found by subtracting the two individual angular diameter distances! The correct formula, for WebTo determine the distance to a galaxy one would only need to measure its apparent (angular) size, and use the small angle equation: a = s / d, where a is the measured …
