Gloria Dubner (born May 5, 1950) is an Argentinian astrophysicist and director of the Instituto de Astronomía y Física del Espacio inBuenos Aires and a senior researcher at theNational Scientific and Technical Research Council. She is known for her research onsupernovas.
Dubner was born on May 5, 1950, in the city ofChajarí, located in theEntre Ríos Province inArgentina. She received herLicentiate degree inphysics in 1974 from theUniversity of Buenos Aires at the age of 23. She then attendedNational University of La Plata, where she received her PhD inphysics in 1982 under the mentorship of astronomer andGuggenheim Fellow Fernando Raúl Colomb.[1]
Between 1975 and 1987, Dubner worked at theArgentine Institute of Radio Astronomy. In 1988, she began working at the Instituto de Astronomía y Física del Espacio (IAFE).[2] In 1997, she also was appointed as a researcher at theNational Scientific and Technical Research Council, continuing her study of supernovas.[3] In 2009, she became the director of IAFE and also serves as the director of the Supernovas and Interstellar Environment group.[4]
Dubner has participated in a number of international collaborations to study galactic supernova remnants. For instance, in 1994, she and her American collaboratorsFrank Winkler and W. Miller Gross were awarded aNational Science Foundation grant to image the expanding shell of gas left over after a star explodes using data collected fromradio telescopes in the US and Argentina.[5]
Starting in 2015, Dubner also led a collaboration between five observatories that led to the production of the most detailed image produced of theCrab Nebula, a brightsupernova explosion first observed by Chinese astronomers in 1054.[6][7][8] The collaboration leveraged data collected at different wavelengths to create a composite image using:infrared data generated by theSpitzer Space Telescope from NASA'sJet Propulsion Laboratory, visible light data from theHubble Space Telescope,ultraviolet data from theXMM-Newton operated by theEuropean Space Agency, radio image and X-ray data from NASA'sChandra X-ray Observatory, and radio data from theVery Large Array operated by theNational Radio Astronomy Observatory.[9]
Dubner is an active member of theInternational Astronomical Union (IAU), serving on a variety of commissions including the Working Group for Historic Radio Astronomy, the Division for Interstellar Matter and Local Universe, and the Commission for Astrochemistry.[10] In 2006, she served on the Organizing Committee to report advances in the field ofradio astronomy between 2002 and 2005.[11] In 2012, she was part of the organizing committee of the IAU's XXVIII General Assembly for Women in Astronomy Meeting.[12] In June 2008, the minor planet9515 Dubner was named in her honor, recognizing her achievements at the IAU.[13] The planet was first discovered at the observatory inEl Leoncito National Park in 1975.[14] In 2023 she won the PlatinumKonex Award as the most important physicist in Argentina.[15][16]
