Summary
[edit]DescriptionGalactic Super Smear - Flickr - geckzilla.png |
Here we have a spectacular example of strong gravitational lensing with a background galaxy forming a nearly complete ring through the lens of a massive foreground cluster. There are four repetitions of the same galaxy, much like the famous Einstein Cross, except a galaxy is an extended object, and therefore it forms a nice ring. Sorry about the fuzzy appearance when it's zoomed in. The IR data has about 1/3 of the resolution of the UVIS data, so I scaled the IR up to match. Hat tip to Dustin Lang spotting this and Observing Monkey over on Twitter for pointing this out to me. You may wish to follow Professor Jha to find out when he publishes his paper on this system! Data from the following proposal were used to create this image: Rings within Rings: High Resolution Imaging of a Spectacular Gravitational Lens (I couldn't agree more with the title for that proposal abstract!) Red: WFC3/IR F160W Green: WFC3/UVIS F775W Blue: WFC3/UVIS F555W North is 26.33° counter-clockwise from up. |
