STOCKHOLM, Sweden, Jan. 20 (UPI) -- Four scientists have shared a total of $1.2 million in this year's Crafoord prizes in astronomy and mathematics, the Royal Swedish Academy of Science said.
The academy rotates the prizes through several disciplines annually, including astronomy and mathematics, geosciences, biosciences and the study of polyarthritis (rheumatoid arthritis).
Reinhard Genzel and Andrea Ghez were awarded the astronomy prize for their work showing a black hole probably resides at the center of the Milky Way.
Genzel works at the Max Planck Institute for Extraterrestrial Physics in Garching, Germany, and Ghez is based at the University of California, Los Angeles, Nature News reported.
The Crafoord prize in mathematics was awarded to Jean Bourgain and Terence Tao.
Tao is based at UCLA and works in multiple areas including harmonic analysis and the study of partial differential equations. Bourgain is with the Institute for Advanced Study in Princeton and also works in harmonics.
The 2013 prize will be awarded for geoscience, the academy said.
