Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline, James Keeler, said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–what they are, rather than where they are." Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, astrophysicists apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.
Virginia Louise Trimble is an American astronomer specializing in the structure and evolution of stars and galaxies, and the history of astronomy. She has published more than 600 works in Astrophysics, and dozens of other works in the history of other sciences. She is famous for an annual review of astronomy and astrophysics research that was published in the Publications of the Astronomical Society of the Pacific, and often gives summary reviews at astrophysical conferences. In 2018, she was elected a Patron of the American Astronomical Society, for her many years of intellectual, organizational, and financial contributions to the society.
Eugene Newman Parker was an American solar and plasma physicist. In the 1950s he proposed the existence of the solar wind and that the magnetic field in the outer Solar System would be in the shape of a Parker spiral, predictions that were later confirmed by spacecraft measurements. In 1987, Parker proposed the existence of nanoflares, a leading candidate to explain the coronal heating problem.
The Center for Astrophysics | Harvard & Smithsonian (CfA), previously known as the Harvard–Smithsonian Center for Astrophysics, is an astrophysics research institute jointly operated by the Harvard College Observatory and Smithsonian Astrophysical Observatory. Founded in 1973 and headquartered in Cambridge, Massachusetts, United States, the CfA leads a broad program of research in astronomy, astrophysics, Earth and space sciences, as well as science education. The CfA either leads or participates in the development and operations of more than fifteen ground- and space-based astronomical research observatories across the electromagnetic spectrum, including the forthcoming Giant Magellan Telescope (GMT) and the Chandra X-ray Observatory, one of NASA's Great Observatories.
Dame Carole Jordan,, is a British physicist, astrophysicist, astronomer and academic. Currently, she is Professor Emeritus of Astrophysics at the University of Oxford and Emeritus Fellow at Somerville College, Oxford. From 1994 to 1996, she was President of the Royal Astronomical Society; she was the first woman to hold this appointment. She won the Gold Medal of the Royal Astronomical Society in 2005; she was only the third female recipient following Caroline Herschel in 1828 and Vera Rubin in 1996. She was head of the Rudolf Peierls Centre for Theoretical Physics at the University of Oxford from 2003 to 2004 and 2005 to 2008, and was one of the first female professors in Astronomy in Britain. She was made a Dame Commander of the Order of the British Empire in 2006 for services to physics and astronomy.

Marie E. Machacek is an astrophysicist conducting research in the High Energy Astrophysics Division of the Smithsonian Astrophysical Observatory. She earned a BA in physics and mathematics from Coe College, in 1969; an MS in physics from the University of Michigan, in 1970; and a PhD in physics from the University of Iowa, in 1973. Her current research explores interacting galaxies and the evolution of galaxies in galaxy groups and clusters. She is also the current coordinator for the SAO Astronomy Intern Program.
Katharine Reeves is an astronomer and solar physicist who works at the Center for Astrophysics | Harvard & Smithsonian (CfA).. She is known for her work on high temperature plasmas in the solar corona, and measurement/analysis techniques to probe the physics of magnetic reconnection and thermal energy transport during solar flares; these are aspects of the coronal heating problem that organizes a large part of the field. She has a strong scientific role in multiple NASA and international space missions to observe the Sun: Hinode ; IRIS ; SDO; Parker Solar Probe; and suborbital sounding rockets including the MaGIXS and Hi-C FLARE high-resolution spectral imaging packages.
Vassiliki Kalogera is a Greek astrophysicist. She is a professor at Northwestern University and the Director of the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA). She is a leading member of the LIGO Collaboration that observed gravitational waves in 2015.
