Slipher galaxy redshift measurements
E1529102
UNEXPLORED
Slipher galaxy redshift measurements are early 20th-century spectroscopic observations by Vesto Slipher that first revealed significant radial velocities of spiral nebulae, laying crucial groundwork for the discovery of the expanding universe.

How this entity was disambiguated
This entity first appeared as the object of triple T22275368 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Hubble–Humason galaxy redshift measurements
The Hubble–Humason galaxy redshift measurements are a landmark set of observations that extended and refined Edwin Hubble’s work on the expanding universe by systematically measuring the redshifts of distant galaxies.
-
B.
A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae
"A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae" is Edwin Hubble’s landmark 1929 paper that established the linear relationship between galaxies’ distances and their recessional velocities, providing the first strong evidence for the expanding universe.
-
C.
“A New Method of Determining Distances to Galaxies”
“A New Method of Determining Distances to Galaxies” is a scientific paper that presents an innovative technique for measuring the distances to external galaxies, contributing to more accurate extragalactic distance scaling in astronomy.
-
D.
Zwicky catalog of galaxies
The Zwicky catalog of galaxies is an influential astronomical catalog compiled by Swiss astronomer Fritz Zwicky that systematically lists and classifies thousands of galaxies and galaxy clusters.
-
E.
Tully-Fisher relation distances
Tully-Fisher relation distances are galaxy distance measurements derived from the empirical correlation between a spiral galaxy’s luminosity and its rotational velocity.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
