Astrophysicist Patrick Brady at the University of Wisconsin-Milwaukee yesterday began his duties as spokesperson for the international scientific collaboration that studies gravitational waves using the Laser Interferometer Gravitational-Wave Observatory (LIGO). The spokesperson of the LIGO Scientific Collaboration (LSC) speaks on behalf of the 1,300 scientists in 20 countries who are engaged in gravitational wave research with data from observatories located in Hanford, Washington, and Livingston, Louisiana. Brady, a UWM professor of physics and director of the Leonard E. Parker Center for Gravitation, Cosmology and Astrophysics, is sixth in an elite group of scientists who have served as LSC spokespersons since the LSC formed in the late 1990s. Former spokespersons were Nobel Prize winner Rainer Weiss (Massachusetts Institute of Technology), Peter Saulson (Syracuse University), Dave Reitze (Caltech), Gabriela Gonzalez (Louisiana State University) and David Shoemaker (MIT). Brady’s research focuses on the analysis and interpretation of data from the network of gravitational-wave detectors. He served on the executive committee of the LSC from 2004-2006, and has co-chaired the LSC Inspiral Analysis Group and chaired the LSC Data Analysis Software Working Group. He joined the UW-Milwaukee faculty in 1999, after a fellowship at Caltech. In 2010 he was elected a Fellow of the American Physical Society, and he shared in the 2016 Special Breakthrough Prize.

Professor Kshitij Thorat is an astronomer and an associate professor at the University of Pretoria (UP). He is a member of UP’s astronomy group within the Department of Physics at the Faculty of Natural and Agricultural Sciences. He specialises in doing research with the MeerKAT telescope and using artificial intelligence (AI) in astronomy. He’s part of the team that has solved the mystery of X-shaped radio galaxies with the help of striking images from the MeerKAT telescope and second author of the study whose results will be published in the Monthly Notices of the Royal Astronomical Society.

University of Pretoria (UP) astrophysicist Professor Roger Deane was part of the international group of scientists who have captured the first image of a black hole. His group worked to develop simulations of the complex, Earth-sized telescope used to make this historic discovery. These simulations attempt to mimic and better understand the data coming from the real instrument, which is made up of antennas across the globe.

About four years ago, Prof Deane started working with the team on the Event Horizon Telescope (EHT), which captured the image that was globally released today (Please see up.ac.za for the official media release). Prof Deane, who grew up in Welkom in the Free State, developed a passion for astronomy from an early age, when he was dazzled by the excellent view of the Milky Way.”
