Idit Zehavi (Hebrew: עדית זהבי; born 1969) is an Israeli astrophysicist and researcher who discovered an anomaly in the mapping of the cosmos, which offered insight into how the universe is expanding. She is part of the team completing the Sloan Digital Sky Survey and is one of the world's most highly cited scientists according to the list published annually by Thomson Reuters.

## Biography

[edit]

Idit Zehavi was born in Israel in 1969[1] and completed her education in Jerusalem, earning a PhD from the Racah Institute of Physics at the Hebrew University of Jerusalem in 1998.[2] That same year, while researching the expansion of the universe, she and a colleague, Avishai Dekel, noted an anomaly in the cosmos which suggested that the portion of the galaxy where earth lies is expanding faster than the entirety of the universe. The findings were independently noted by another researcher, Adam Riess, from the University of California, Berkeley.[3] Soon after, Zehavi moved to the United States to complete her post-doctorate studies in galaxy clustering at the University of Chicago and participate in research at the Fermi National Accelerator Laboratory.[4] She left Fermilab in 2004 for the University of Arizona and continued working on the research of the Sloan Digital Sky Survey (SDSS).[5] In 2005, she participated in research under the direction of Daniel Eisenstein, which detected "cosmic ripples",[6] which confirmed the cosmological theory of the creation of the universe.[7]

In 2006, she joined Case Western Reserve University of Cleveland, Ohio, as an Associate Professor in the Astronomy Department.[1][8] In 2009, Zehavi was awarded a grant from the U.S. National Science Foundation to continue her work with the SDSS to expand her work on galaxy clustering to encompass a larger scale view of the universe.[9] According to the annual listing produced by Thomson Reuters, Zehavi is one of the world's most highly cited scientists.[10]
