Blog; Seasons Greetings from Space Warps: Some Refined Lenses, and a Big Thank You! Phil, Aprajita and Anupreeta Dec 19, 2013 http://blog.spacewarps.org/2013/12/19/seasons-greetings-from-space-warps-some-refined-lenses-and-a-big-thank-you/ "Well, Space Warps Refine has been running for just over a week, and it’s had a fantastic response from you all. THANK YOU! With over 140,000 classifications of the 3679 images, we have very good data on almost all of them – and some exciting new lens candidates are popping out of the pipeline!"

Blog: It’s good to Talk! Why we need to hear from you to find Space Warps by Aprajita June 14, 2013
by Aprajita http://blog.spacewarps.org/2013/06/14/its-good-to-talk/ "Most excitingly, some of you have started discussing a few lens candidates that we think have been missed by the algorithms"

Blog: Trailer: Results from CFHTLS April 23, 2015 by Phil Marshall http://blog.spacewarps.org/2015/04/23/trailer-results-from-cfhtls/ " We’re currently in the process of posting two papers from the CFHTLS project, but one (that describes the system) is stuck in the works for being too massive. (Insert gravitational lensing joke here.)" 😃 !!!

Blog: Space Warps: New Candidate Gravitational Lenses in the CFHTLS! April 24, 2015 by Aprajita " It’s good news: in addition to finding 80 previously published candidate gravitational lenses, you helped discover 28 new candidate gravitational lenses (and another 30 objects that might turn out be lenses). Nice work, people!"

A,G arc around galaxy group pr 1.0

http://talk.spacewarps.org/#/subjects/ASW0004dv8 talk

enter image description here

used as an example in blog http://blog.spacewarps.org/2013/08/15/x-marks-the-spot-new-gravitational-lens-candidates-from-space-warps/ "Here, the collective mass of the foreground group of yellow galaxies (primarily the two bright galaxies) is large enough to bend the light of a blue galaxy lying behind forming a beautiful blue arc. There are some fainter and smaller yellow galaxies spread across the field that are also likely to be members of the galaxy group. Such galaxy groups (and the more massive clusters of galaxies) mark the most massive and dense regions of dark matter in the Universe. In contrast, the background blue galaxy that is being lensed into an arc is of much lower mass. It’s blue because it has many younger stars, and only just forming the bulk of its stars."

We think this probably wasn’t picked up by the robotic ArcFinder because it has such low surface brightness, and the field is so crowded. "

http://blog.spacewarps.org/2013/08/15/x-marks-the-spot-new-gravitational-lens-candidates-from-space-warps/" On a quick glance, the nearby bright star might have grabbed your attention sooner than the potential lensed arc. Just to the left of the star in the image below, there’s a nice clear arc next to the yellow lensing galaxy. Other similarly coloured yellow galaxies in this image that may form a galaxy group."

enter image description here

"On initial inspection, this looks to be like the examples above, a blue arc around a yellow galaxy. However, if you look closely at the arc, it’s not as smooth as the blue arcs in the examples above. The lensed blue feature actually comprises three blue emission peaks that are aligned in a “cusp”-like configuration around the primary lensing galaxy. Also there is a neighbouring small galaxy to the right of the primary lens that may also contribute to the gravitational lens. To verify this we would need to make a lens model to try and explain the image features we see. Using custom software, we program in the position, extent and mass of a lens (a single galaxy or group of galaxies), then place a virtual distant blue galaxy behind it, and then try to reproduce the shape and light of the lensed blue arc or features"

http://blog.spacewarps.org/2013/12/19/seasons-greetings-from-space-warps-some-refined-lenses-and-a-big-thank-you/ "Here’s another good one: a binary lens? The blue arc looks like its composed of three merging images of a small blue background galaxy, strongly lensed by the lower red galaxy. But what’s that yellow object? It’s a little bigger than a star would be, so it’s probably another massive galaxy – and its colour suggests that it’s at a lower redshift than the lens galaxy. If it is in the foreground, then it is lensing both the blue arc, and the red lens! So-called “compound lenses” like these are very interesting: we might be able to learn about the mass of the yellow galaxy as well as the red one. With enough examples of systems like this we might even be able to say something about how fast the Universe is expanding…

Tom’s written a paper on this that you might find interesting." http://arxiv.org/abs/1203.2758 http://arxiv.org/pdf/1203.2758v2.pdf (no pictures!) Constraining the dark energy equation of state with double source plane strong lenses
