Ronald David Ekers(born 18 September 1941) FRS FAA is an Australian radio astronomer. His fields of specialty include the study of active galactic nuclei, cosmology, and radio astronomy techniques.
Ron Ekers was born in Victor Harbor, South Australia. He showed interest in astronomy at a young age.
Ron Ekers graduated from the University of Adelaide in 1963 and received his PhD in astronomy at the Australian National University (ANU) in 1967. His postdoctoral supervisor at ANU was the astronomer John Gatenby Bolton. After graduating from ANU, his first postdoctoral studies were performed at Caltech, during which time Richard P. Feynman and Fred Hoyle were active. When Ron was in his teenage years, he bought a telescope and recorded the position of stars.
He was director of the Very Large Array (VLA) from 1980 until 1987. From 1988 to 2003 he was Foundation Director of CSIRO's Australia Telescope National Facility. In 2002 he was awarded a prestigious Federation Fellowship. He is a past President of the International Astronomical Union (IAU) (2003–2006) and a member of the Advisory Board for the Peter Gruber Foundation Cosmology Prize.
He was elected a Fellow of the Australian Academy of Science, a Foreign Member of the Royal Netherlands Academy of Arts and Sciences in 1993,a Foreign Member of the American Philosophical Society in 2003, a Fellow of the Royal Society in 2005, and a Foreign Associate of the US National Academy of Sciences in 2018.
Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was in 1932, when Karl Jansky at Bell Telephone Laboratories observed radiation coming from the Milky Way. Subsequent observations have identified a number of different sources of radio emission. These include stars and galaxies, as well as entirely new classes of objects, such as radio galaxies, quasars, pulsars, and masers. The discovery of the cosmic microwave background radiation, regarded as evidence for the Big Bang theory, was made through radio astronomy.
Grote Reber was an American pioneer of radio astronomy, which combined his interests in amateur radio and amateur astronomy. He was instrumental in investigating and extending Karl Jansky's pioneering work, and conducted the first sky survey in the radio frequencies.
Bartholomeus Jan "Bart" Bok was a Dutch-American astronomer, teacher, and lecturer. He is best known for his work on the structure and evolution of the Milky Way galaxy, and for the discovery of Bok globules, which are small, densely dark clouds of interstellar gas and dust that can be seen silhouetted against brighter backgrounds. Bok suggested that these globules may be in the process of contracting, before forming into stars.

James Edward Gunn is the Eugene Higgins Professor of Astronomy at Princeton University. Gunn's early theoretical work in astronomy has helped establish the current understanding of how galaxies form, and the properties of the space between galaxies. He also suggested important observational tests to confirm the presence of dark matter in galaxies, and predicted the existence of a Gunn–Peterson trough in the spectra of distant quasars.
Joseph Lade Pawsey was an Australian scientist, radiophysicist and radio astronomer.
Brian Paul Schmidt is the Vice-Chancellor of the Australian National University (ANU). He was previously a Distinguished Professor, Australian Research Council Laureate Fellow and astrophysicist at the University's Mount Stromlo Observatory and Research School of Astronomy and Astrophysics. He is known for his research in using supernovae as cosmological probes. He currently holds an Australia Research Council Federation Fellowship and was elected a Fellow of the Royal Society (FRS) in 2012. Schmidt shared both the 2006 Shaw Prize in Astronomy and the 2011 Nobel Prize in Physics with Saul Perlmutter and Adam Riess for providing evidence that the expansion of the universe is accelerating, making him the only Montana-born Nobel laureate.
Lisa Jennifer Kewley is a Professor and Director of the ARC Centre of Excellence for All Sky Astrophysics in 3-D and ARC Laureate Fellow at the Australian National University College of Physical and Mathematical Sciences. Specialising in galaxy evolution, she won the Annie Jump Cannon Award in Astronomy in 2005 for her studies of oxygen in galaxies, and the Newton Lacy Pierce Prize in Astronomy in 2008. In 2014 she was elected a fellow of the Australian Academy of Science. In 2020 she received the James Craig Watson Medal. In 2021 she was elected as an international member of the National Academy of Sciences.
Kenneth Charles Freeman is an Australian astronomer and astrophysicist who is currently Duffield Professor of Astronomy in the Research School of Astronomy and Astrophysics at the Mount Stromlo Observatory of the Australian National University in Canberra. He was born in Perth, Western Australia in 1940, studied mathematics and physics at the University of Western Australia, and graduated with first class honours in applied mathematics in 1962. He then went to Cambridge University for postgraduate work in theoretical astrophysics with Leon Mestel and Donald Lynden-Bell, and completed his doctorate in 1965. Following a postdoctoral appointment at the University of Texas with Gérard de Vaucouleurs, and a research fellowship at Trinity College, Cambridge, he returned to Australia in 1967 as a Queen Elizabeth Fellow at Mount Stromlo. Apart from a year in the Kapteyn Institute in Groningen in 1976 and some occasional absences overseas, he has been at Mount Stromlo ever since.
The Reber Radio Telescope is a historic radio telescope, located at the Green Bank Observatory near Green Bank, West Virginia. Built in 1937 in Illinois by astronomer Grote Reber, it is the first purpose-built parabolic radio telescope. It was designated a National Historic Landmark in 1989.
Professor Kurt Lambeck AC, FRS, FAA, FRSN is Professor of Geophysics at the Australian National University in Canberra, Australia. He has also taught at University of Paris and at Smithsonian and Harvard Observatories.
Harvey Raymond Butcher III is an astronomer who has made significant contributions in observational astronomy and instrumentation which have advanced understanding of the formation of stars and of the universe. He received a B.Sc. in Astrophysics from the California Institute of Technology in 1969, where he contributed to the development of advanced infrared spectrometry applied in the first survey of the sky at infrared wavelengths.
Govind Swarup was a radio astronomer and one of the pioneers of radio astronomy, known not only for his many important research contributions in several areas of astronomy and astrophysics, but also for his outstanding achievements in building ingenious, innovative and powerful observational facilities for front-line research in radio astronomy. He was the key scientist behind concept, design and installation of the Ooty Radio Telescope (India) and the Giant Metrewave Radio Telescope (GMRT) near Pune. Under his leadership, a strong group in radio astrophysics has been built at Tata Institute of Fundamental Research that is comparable to the best in the world.
Marek Janusz Kukula is a British astronomer and an author of works on popular science.
