Webinar Especial Semanaldo Observatório do Valongo com Dr. John C. Mather, prêmio Nobel de Física

Data do Evento: 
terça-feira, 8 Junho, 2021 - 14:00
Temos o prazer de anunciar que o Dr. John C. Mather, prêmio Nobel de Física, será o convidado especial dos seminários semanais do Observatório do Valongo no dia 08/06, às 14h. O Dr. Mather, atualmente Cientista de Projetos Sênior do telescópio espacial James Webb, apresentará uma palestra sobre os resultados esperados com o lançamento, em alguns meses.

Opening the Infrared Treasure Chest with JWST

Dr. John C. Mather

The long-awaited James Webb Space Telescope is planned for launch by Oct. 31, 2021. With its 6.5 m deployable primary mirror, and cameras and spectrometers covering 0.6 to 28 µm, it promises extraordinary improvements in observing capabilities. Webb will be able to observe the first objects that formed after the Big Bang, the growth of galaxies, the formation of stars and planetary systems, individual exoplanets through coronography and transit spectroscopy, and all objects in the Solar System from Mars on out. It could observe a 1 cm2 bumblebee at the distance of the Moon, in reflected sunlight and thermal emission. I will review the observatory capabilities and planned observing program, and illustrate the history of the concept from 1988 to now. The Webb is a joint project of NASA with the European and Canadian space agencies.
About the speaker

Dr. John C. Mather is an American astrophysicist, cosmologist and Nobel Prize in Physics laureate for his work on the Cosmic Background Explorer Satellite (COBE) with George Smoot. This work helped cement the big-bang theory of the universe. According to the Nobel Prize committee, "the COBE-project can also be regarded as the starting point for cosmology as a precision science."

Mather is a senior astrophysicist at the NASA Goddard Space Flight Center (GSFC) in Maryland and adjunct professor of physics at the University of Maryland College of Computer, Mathematical, and Natural Sciences. In 2007, Mather was listed among Time magazine's 100 Most Influential People in The World. In October, 2012, he was listed again by Time magazine in a special issue on New Space Discoveries as one of 25 most influential people in space. 

As an NRC postdoctoral fellow at the Goddard Institute for Space Studies (New York City), he led the proposal efforts for the Cosmic Background Explorer (74-76), and moved to GSFC to be the Study Scientist (76-88), Project Scientist (88-98), and also the Principal Investigator for the Far IR Absolute Spectrophotometer (FIRAS) on COBE. He showed that the cosmic microwave background radiation has a blackbody spectrum within 50 ppm. As Senior Project Scientist (95-present) for the James Webb Space Telescope, he leads the science team, and represents scientific interests within the project management. He has served on advisory and working groups for the National Academy of Sciences, NASA, and the NSF (for the ALMA, the Atacama Large Millimeter Array, and for the CARA, the Center for Astrophysical Research in the Antarctic).
