Kolkata-born Indian-American astrophysicist Sukanya Chakrabarti has been elected a Fellow of the American Physical Society (APS), one of the leading professional honours in the physics community. The recognition highlights her research into dark matter and efforts to develop innovative methods to understand its distribution across the Milky Way.
Chakrabarti serves as the Pei-Ling Chan Endowed Chair in the College of Science at the University of Alabama in Huntsville. Her research focuses on detecting dark matter by measuring the extremely small accelerations it produces in stars and other astronomical objects.
Expressing her appreciation for the recognition, Chakrabarti said she had been developing new approaches to mapping dark matter throughout the Galaxy. Her work uses highly precise astronomical measurements to investigate the gravitational effects of matter that cannot be observed directly through conventional light-based observations.
By combining precision measurements of stars, pulsars and eclipsing binary systems, her research team aims to identify dark matter concentrations on increasingly smaller scales. These structures could provide important clues about the nature and behaviour of dark matter.
Dark matter remains one of the biggest unanswered questions in modern physics. Although it cannot be directly observed through emitted or reflected light, scientists infer its existence from its gravitational influence on stars, galaxies and the large-scale structure of the universe.
Understanding how dark matter is distributed could help researchers distinguish between competing theoretical models and explain how galaxies form and evolve.
Chakrabarti’s approach seeks to use the subtle gravitational effects of dark matter as a tool for identifying its otherwise invisible structures. By studying how astronomical objects move, researchers can investigate the presence of dark matter concentrations that might otherwise remain undetected.
The American Physical Society’s fellowship recognises significant contributions to physics. Chakrabarti’s election highlights the importance of her research and the broader scientific effort to address fundamental questions about the universe.
Her achievement also adds to the growing international recognition of scientists of Indian origin working at the forefront of scientific research. Through precision astronomy and innovative observational techniques, Chakrabarti and her collaborators are working to advance understanding of one of the universe’s most enduring mysteries.
