India, March 30 -- Two astronomers from Pune are part of a research team that has developed a method to correct errors in measuring galaxy distances, a crucial step toward improving our understanding of the Universe's structure, dark matter, and cosmic evolution.

Prof. Surhud More from the Inter-University Centre for Astronomy and Astrophysics, Pune and Divya Rana, a former student of the centre currently at Leiden University, along with their international collaborators proposed a novel geometrical approach called the 'shear ratio method'. Their findings have been published in the international journal, Physical Review D.

A central concept in measuring galaxy distances is 'redshift': the measure of how much light from distant galaxies ...
