A recent study by a team of scientists using the AstroSat (India’s first dedicated multi wavelength space observatory) shows how the star-forming complexes in the outskirts of a dwarf galaxy migrate towards the central region and contribute to its growth in mass and luminosity. The processis an important link to understanding the bigger picture of the growth and evolution of galaxies. The research was jointly carried out by an international team of astronomers from India, the USA and France. The study was conceived by professor Kanak Saha at the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, and was published as a research paper on July 20 in the Nature journal. Anshuman Borgohain, the lead author of the paper, is a PhD student at the Tezpur University, Assam, working under the supervision of professor Rupjyoti Gogoi, who is a visiting associate at IUCAA, besides being a contributor to the research.
