When was sandra faber born

Schmadel , and Charles Piazzi Smyth. Among people born in , Sandra Faber ranks Among people born in United States , Sandra Faber ranks 5, out of 15, Before her are Gerard K. In , Faber obtained a B. She went on to receive her Ph.

Faber was the head of a team known as the Seven Samurai that discovered a mass concentration called "The Great Attractor". She was also the Principal Investigator of the Nuker Team, which used the Hubble Space Telescope to search for supermassive black holes at the centers of galaxies.

She has made important discoveries linking the brightness of galaxies to the speed of stars within them and was the co-discoverer of the Faber—Jackson relation. Faber was also instrumental in designing the Keck telescopes in Hawaii.

Gallagher published a seminal paper collecting all of the evidence for the existence of dark matter that had been published at that point. In , she published original research showing that dark matter was not composed of fast-moving neutrinos "hot dark matter" and that instead, it was likely composed of slow-moving particles yet to be discovered "cold dark matter". Around , Faber collaborated with Joel Primack , George Blumenthal , and Martin Rees to elucidate their theory of how dark matter was part of galaxy formation and evolution.

This was the first proposal of how galaxies have formed and evolved from the Big Bang to today. While some details have been proven wrong, the paper still stands as the current working paradigm for structure information in the universe.

She and her collaborators discovered high-speed galaxy flows. In , Faber was involved with the construction of the Keck Telescope and building the first wide-field planetary camera for the Hubble Space Telescope. UC Berkeley physicist Jerry Nelson designed the Keck telescope, but Faber helped to sell the idea of large optical telescopes all over the world.

The Keck telescope is the second largest optical telescope in the world, with a meter primary mirror of a novel type that consists of 36 hexagonal segments. She also continued to insist on high optical quality for the primary mirror of the Keck I, and went on to work on the Keck II as well. During the later s, Faber got involved in an eight-year project called the "Seven Samurai" collaboration, which attempted to catalogue the size and orbital speeds of galaxies.

Though this goal was not met, the group developed a way to estimate the distance to any galaxy, which became one of the most reliable ways to measure the total density of the universe.
