description Sandra Faber Overview

Sandra Faber is a prominent modern astronomer specializing in the study of galaxy evolution. Her work has significantly advanced our understanding of how galaxies form and change over time. Notably, she co-discovered the Faber-Jackson relation, a key correlation describing the luminosity of elliptical galaxies based on their size. This research is primarily valuable for astronomers and cosmologists investigating large-scale structure and the formation history of the universe.

help Sandra Faber FAQ

What is the Faber-Jackson relation, and why is it important?

Discovered with Robert Jackson in 1976, the Faber-Jackson relation establishes that the luminosity of an elliptical galaxy is proportional to the velocity dispersion of its stars. It provided astronomers with a vital tool to estimate the distances to elliptical galaxies based on their observable brightness.

Did Sandra Faber help design the Hubble Space Telescope?

Yes, Sandra Faber was heavily involved in the planning and instrumentation of the Hubble Space Telescope. She co-authored a proposal for the Wide Field and Planetary Camera, one of the primary instruments used to capture Hubble's famous early deep-space images.

What observatory did Sandra Faber work at for most of her career?

Faber spent the majority of her prestigious career working as an astronomer at the Lick Observatory, operated by the University of California. From there, she utilized the Shane 3-meter telescope to study galaxy formation and dark matter.

What major scientific award did Sandra Faber receive?

Sandra Faber was awarded the National Medal of Science by President Barack Obama in 2013. She was recognized for her lifelong contributions to understanding the evolution of the universe and the role of dark matter in galaxy formation.
