After her moliage to mathematician Robert Rubin, who was completing his Ph.D. at Cornell, the couple moved to Washington, D.C. Vera consured her doctorate at Georgetown University, balancing graduate studies with raising her growing family (she would eventually have four children, all of whom became scientsts).

In a 1970 paper one the Andromeda Cameda, Rubin Ford wrote quet: thee rotione cure risene steeple thee inner 3 ked, then, these.

Something invisible was present - a division; dark matter; halo that extended far beyen thee visible disk.

Thee Impact of Rubin 's Discosieres on Modern Cosmology

Shifting the Paradigm of the Universe

Before Rubin 's work, the standard coslogical model posited a universe made mostly of ordinary atomic matter, with stars andd gas dimensiing the bull of it mas. After her rotation curve merurements, astronoms had to accept that the visiblee uniste - everthing we e can see with telcopes - is merely the tip of an iceberg.

From Galaxy Rotation to the Cosmic Web

Rubin 's rotation curves were just the first step. Subsequent observations of preseny clusters (using X- ray emission frem hot gas andd gravitational lensing) and the cosmic microva background (especially by th WMAP andd Planck satellites) have rephane our concepting of dark matter' s role.
