There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Matter overdensity (top row) and ionized fraction (bottom row) for the three regions simulated in the Renaissance Simulations. The red triangles represent the locations of galaxies that are detectable with the Hubble Space Telescope. Its successor, the James Webb Space Telescope, will detect many more distant galaxies, shown by the blue squares and green circles. These first galaxies reionized the universe only 1 billion years after the Big Bang, shown in the image with ionized (blue) bubbles around the galaxies. Image: Brian W.
