Vera Florence Cooper Rubin (/ ˈ r uː b ɪ n /; July 23, 1928 – December 25, 2016) was an American astronomer who pioneered work on galaxy rotation rates. [ 1 ] [ 2 ] She uncovered the discrepancy between the predicted and observed angular motion of galaxies by studying galactic rotation curves .
She used galaxies' rotations to discover the first direct evidence of dark matter in the 1970s while working at the Carnegie Institution in Washington.
1981: Vera Rubin was the second female astronomer elected to the National Academy of Science. Beginning her academic career as the sole undergraduate in astronomy at Vassar College , Rubin went on to graduate studies at Cornell University and Georgetown University , where she observed deviations from Hubble flow in galaxies and provided ...
In an important paper co-authored with astronomer Vera Rubin in 1970, [6] and a follow-up paper in 1980, [7] Rubin and Ford established that the orbits of stars around the center of galaxies (the "galaxy rotation curve") does not decrease with distance from the galactic center, as expected from Kepler's rotation law, but remains constant (or "flat") with distance.
Robert Joshua Rubin (/ ˈ r uː b ɪ n /; August 17, 1926 – January 18, 2008) [1] was an American mathematician whose work involved modelling complex physical systems. [2] He worked principally at the National Bureau of Standards, and was a Fellow of the American Association for the Advancement of Science and also a Fellow of the American Physical Society.

Buckley added that Rubin's death was sudden, saying "he was here with us yesterday." In a statement on social media, KTLA shared, "KTLA 5 is profoundly saddened to report the death of Sam Rubin.
