Dr. John Mulchaey, Acting Director, Carnegie Observatories in PasadenaThe light we see with our eyes only tells a small part of the Universe's story. To get a complete picture of how the Universe works, astronomers must study objects over the full range of light, the electromagnetic spectrum. This includes gamma rays, X-rays, ultraviolet, visible, infrared, micro- waves and radio waves. Each type of light requires different instruments, and provides unique information about the source that emitted it. Join us on Wednesday when Dr. Mulchaey will explain how Carnegie astronomers and their colleagues are combining observations across the electromagnetic spectrum to help solve the mysteries of the Universe.
Dr. Mulchaey holds a Ph.D. from the University of Maryland and has been a Carnegie astronomer for over 20 years. He studies groups and clusters of galaxies, elliptical galaxies, dark matter, active galaxies and black holes. He is also actively involved in public outreach and education.
The Carnegie Observatories was founded by George Ellery Hale in 1904. Located in Pasadena, California, the Observatories operates telescopes on Cerro Las Campanas, Chile. The Carnegie Institution (www.CarnegieInstitution.org) has been a pioneering force in basic scientific research since 1902. It is a private, nonprofit organization with six research departments throughout the U.S.
