-
A.
A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae
chosen
"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.
-
B.
Tolman surface brightness test
The Tolman surface brightness test is an observational cosmology method that checks whether the universe is expanding by examining how the surface brightness of distant galaxies diminishes with redshift.
-
C.
Faber–Jackson relation paper
The Faber–Jackson relation paper is a landmark astrophysics publication that established a correlation between the luminosity and stellar velocity dispersion of elliptical galaxies, providing key insights into their structure and evolution.
-
D.
Hubble sequence of galaxy classification
The Hubble sequence of galaxy classification is a morphological system that organizes galaxies into categories such as ellipticals, spirals, and irregulars based on their visual appearance.
-
E.
The Expanding Universe
"The Expanding Universe" is a chapter in Stephen Hawking’s popular science book *A Brief History of Time* that explains how observations and cosmological theory reveal that the universe is growing larger over time.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
