Summary[edit]
DescriptionColor composite image using data from both Gemini and the NOT (geminiann15012a).tiff |
English: 30"x30" color composite g+r+i image using data from both Gemini and the NOT, highlighting the three brighter lensed quasar images for which time delays have now been measured. Image C leads all other images of the quasar by several years, and hence predicts the future behaviour. Lensing of quasars is achromatic, but the NOT data (r,i) and Gemini data (g) were taken at different times, and hence image C appears in this composite to be a different color than images A and B. |
