  • The ‘triple’ quasar, PG1115 +08 (which actually contains at least four objects: A1, A2, B and C) was the second gravitational lens object to be found1. But because of its small angular scale (<2.5 arc s separation between components) and lack of detectable radio emission, which precludes the use of high-resolution interferometric radio techniques, not much is known about this object. In particular, the lensing object(s) have not been identified. Here we report imaging observations made on a… CONTINUE READING
