Kerstin Fredga (born 1935) is a Swedish astronomer and spectroheliographer whose research involves the spectra of the sun and other stars. She is the former director of the Swedish National Space Agency and former president of the Royal Swedish Academy of Sciences.
Fredga was born in Stockholm in 1935, one of five children of chemistry professor Arne Fredga and his wife, a kindergarten teacher, who encouraged her to pursue her interest in astronomy. After studies at Uppsala University, she completed a Ph.D. in astronomy in 1962. [1]
She began her career working at the Institute for Solar Physics on Capri. After continued research on rocket-based ultraviolet solar observation at the Goddard Space Flight Center in the US, and in the Astronomical Institute and Space Research Laboratory of the University of Utrecht, she returned to Sweden, and in 1973 became a professor at Stockholm University, at the same time moving from research towards academic administration in the Swedish National Space Agency. She was project scientist for Viking, Sweden's first satellite, which launched in 1986, [2] and directed the agency for ten years beginning in 1989. [1] She has also chaired the Space Science Council of the European Space Agency. [3]
Fredga was elected to the Royal Swedish Academy of Sciences in 1978, and later became its president. [1] [3] She was also elected to the Royal Swedish Academy of Engineering Sciences in 1986, and to the Academia Europaea in 1988. [3]
She was the 1983 recipient of the KTH Great Prize of the KTH Royal Institute of Technology, citing "her broad knowledge in astronomy and space physics as well as experiences from American space projects". [4]
The KTH Royal Institute of Technology, abbreviated KTH, is a public research university in Stockholm, Sweden. KTH conducts research and education in engineering and technology and is Sweden's largest technical university. Currently, KTH consists of five schools with four campuses in and around Stockholm.
Sandra Moore Faber is an American astrophysicist known for her research on the evolution of galaxies. She is the University Professor of Astronomy and Astrophysics at the University of California, Santa Cruz, and works at the Lick Observatory. She has made discoveries linking the brightness of galaxies to the speed of stars within them and was the co-discoverer of the Faber–Jackson relation. Faber was also instrumental in designing the Keck telescopes in Hawaii.
Hannes Olof Gösta Alfvén was a Swedish electrical engineer, plasma physicist and winner of the 1970 Nobel Prize in Physics for his work on magnetohydrodynamics (MHD). He described the class of MHD waves now known as Alfvén waves. He was originally trained as an electrical power engineer and later moved to research and teaching in the fields of plasma physics and electrical engineering. Alfvén made many contributions to plasma physics, including theories describing the behavior of aurorae, the Van Allen radiation belts, the effect of magnetic storms on the Earth's magnetic field, the terrestrial magnetosphere, and the dynamics of plasmas in the Milky Way galaxy.
Antony Hewish was a British radio astronomer who won the Nobel Prize for Physics in 1974 for his role in the discovery of pulsars. He was also awarded the Eddington Medal of the Royal Astronomical Society in 1969.
Catherine Jeanne Cesarsky is an Argentine and French astronomer, known for her research activities in astrophysics and for her leadership in astronomy and atomic energy. She is the current chairperson of the Square Kilometre Array's governing body, SKAO Council. She was the first female president of the International Astronomical Union (2006-2009) and the first female director general of the European Southern Observatory (1999-2007).
Michele Karen Dougherty is a British astrophysicist who is a Professor of Space Physics at Imperial College London. She is leading unmanned exploratory missions to Saturn and Jupiter and is Principal Investigator for J-MAG – a magnetometer for the European Space Agency's Jupiter Icy Moons Explorer, launched in April 2023.
Leonard John Celistus Culhane FRS is an Irish-born British astronomer, former director of the Mullard Space Science Laboratory at University College London.
Claudia Megan Urry is an American astrophysicist, who has served as the President of the American Astronomical Society, as chair of the Department of Physics at Yale University, and as part of the Hubble Space Telescope faculty. She is currently the Israel Munson Professor of Physics and Astronomy at Yale University and Director of the Yale Center for Astronomy and Astrophysics. Urry is notable not only for her contributions to astronomy and astrophysics, including work on black holes and multiwavelength surveys, but also for her work addressing sexism and sex equality in astronomy, science, and academia more generally.
Natalie M. Batalha is professor of Astronomy and Astrophysics at UC Santa Cruz. Previously she was a research astronomer in the Space Sciences Division of NASA Ames Research Center and held the position of Science Team Lead, Mission Scientist, and Project Scientist on the Kepler Mission, the first mission capable of finding Earth-size planets around other stars. Before moving to NASA, Batalha was a Professor of Physics and Astronomy at San Jose State University.
Louise Harra is a Northern Irish physicist, born in Lurgan, County Armagh, Northern Ireland. She is the Director of the World Radiation Centre of the Physical Meteorological Observatory in Davos (PMOD/WRC) and affiliated professor at the Institute of Particle Physics and Astrophysics of ETH Zurich.
Heino Falcke is a German professor of radio astronomy and astroparticle physics at the Radboud University Nijmegen (Netherlands). His main field of study is black holes, and he is the originator of the concept of the 'black hole shadow'. In 2019, Falcke announced the first Event Horizon Telescope results at the EHT Press Conference in Brussels.
Johannes Alphonsus Marie "Johan" Bleeker is a Dutch space research and technology scientist. He was director of the Netherlands Institute for Space Research from 1983 to 2003. He was involved in the setting up of the Horizon 2000 and Horizon 2000+ long term space science programs of the European Space Agency.
Hiranya Vajramani Peiris is a British astrophysicist at the University of Cambridge, where she holds the Professorship of Astrophysics (1909). She is best known for her work on the cosmic microwave background radiation, and interdisciplinary links between cosmology and high-energy physics. She was one of 27 scientists who received the Breakthrough Prize in Fundamental Physics in 2018 for their "detailed maps of the early universe".
Lyndsay Fletcher is a Scottish astrophysicist at the University of Glasgow who specialises in solar flares.
The Institute of Theoretical Astrophysics is a research and teaching institute dedicated to astronomy, astrophysics and solar physics located at Blindern in Oslo, Norway. It is a department of The Faculty of Mathematics and Natural Sciences at the University of Oslo. It was founded in its current form by Svein Rosseland with funding from the Rockefeller Foundation in 1934, and was the first of its kind in the world when it opened. Prior to that, it existed as the University Observatory which was created in 1833. It thus is one of the university's oldest institutions. As of 2019, it houses research groups in cosmology, extragalactic astronomy, and The Rosseland Centre for Solar Physics, a Norwegian Centre of Excellence.
