Rare ‘Einstein ring’ discovered

An international team of astrophysicists has stumbled upon an unusual astronomical object — an Einstein ring which is a distorted image of a very distant galaxy termed as “the source”.

The distortion is produced by the bending of the light rays from the source due to a massive galaxy, termed “the lens”, lying between it and the observer.

Doctoral student Margherita Bettinelli from the Instituto de Astrofisica de Canarias (IAC) and the University of La Laguna (ULL) discovered the phenomenon. The results were published in the international journal Monthly Notices of the Royal Astronomical Society . — IANS
