Astronomers Find a Rare 'Einstein Cross' -by spacewriter
This latest Einstein Cross has some interesting statistics. The main galaxy doing the lensing lies about 5.998 billion light-years away. The distant galaxy that it’s lensing is more than 11.179 billion light-years away. Thus, the foreground lensing galaxy is giving an amazing look at a galaxy in the early Universe.
The astronomy team determined the distance to the more distant galaxy by doing a spectral analysis of the light in each image. Based on color information contained in the DESI Legacy Survey, the team thinks that the lensing galaxy is in a galaxy group. They found at least seven other members of the same group. They describe those galaxies as “passive”, which could mean they are all older or elliptical. However, there’s not enough information to completely describe the galaxy group.
In their paper, the astronomers point out this is the first time data from a real gravitational lensing system got modeled in this way using GIGA-Lens. They write, “This concretely demonstrates a very promising future of modeling of strong lensing systems that are expected to be discovered in the next decade , in a fast, robust, and scalable way.
