** This entry is dedicated to the life and work of Dr. **Evelyn B. Thompson**, a renowned American astrophysicist who made groundbreaking contributions to our understanding of **dark matter** and **galaxy evolution**. ## Overview Dr. **Evelyn B. Thompson** (1955-2020) was an American astrophysicist who spent her career studying the mysteries of the universe. Born in **New York City**, Thompson developed a passion for physics at a young age, which led her to pursue a degree in **astronomy** from **Harvard University**. Her academic journey took her to **Stanford University**, where she earned her Ph.D. in **astrophysics** in 1982. Thompson's research focused on understanding the behavior of **dark matter**, a type of matter that does not emit, absorb, or reflect any electromagnetic radiation, making it invisible to our telescopes. Thompson's work took her to various institutions, including the **California Institute of Technology (Caltech)** and the **Harvard-Smithsonian Center for Astrophysics**. Her research collaborations and mentorship played a significant role in shaping the careers of several prominent astrophysicists. Thompson's dedication to science education and outreach led her to participate in various public engagement initiatives, including the **National Science Foundation's Science and Technology Center**. ## History/Background Thompson's interest in astrophysics was sparked by the **Apollo 11 moon landing** in 1969. She was fascinated by the vastness of space and the mysteries that lay beyond our planet. Her academic journey was influenced by the works of **Subrahmanyan Chandrasekhar**, a Nobel laureate in physics who made significant contributions to our understanding of **stellar evolution**. Thompson's Ph.D. research focused on the **rotation curves of galaxies**, which led her to investigate the presence of dark matter. In the 1990s, Thompson's research team made a groundbreaking discovery using the **Hubble Space Telescope**. They observed the **galaxy rotation curves**, which revealed a discrepancy between the observed and predicted rotation speeds of galaxies. This finding provided strong evidence for the existence of dark matter, a concept first proposed by **Friedmann** in the 1920s. Thompson's work on dark matter led to a deeper understanding of galaxy evolution and the formation of structure in the universe. ## Key Information - **Dark matter**: Thompson's research focused on understanding the behavior of dark matter, which is thought to make up approximately 27% of the universe's mass-energy density. - **Galaxy evolution**: Thompson's work on galaxy rotation curves provided insights into the evolution of galaxies and the role of dark matter in their formation. - **Hubble Space Telescope**: Thompson's team used the Hubble Space Telescope to observe galaxy rotation curves, providing evidence for the existence of dark matter. - **National Science Foundation's Science and Technology Center**: Thompson participated in various public engagement initiatives, including the National Science Foundation's Science and Technology Center. - **California Institute of Technology (Caltech)**: Thompson worked at Caltech, where she collaborated with prominent astrophysicists and contributed to the development of new research initiatives. ## Significance Thompson's contributions to our understanding of dark matter and galaxy evolution have had a significant impact on the field of astrophysics. Her work has inspired a new generation of scientists to pursue research in these areas. Thompson's legacy extends beyond her scientific contributions; she was a dedicated mentor and advocate for science education and outreach. INFOBOX: - Name: **Evelyn B.
