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

The gravitational wave signals from cosmic events measured by LIGO-Virgo from 2015 to 2017. Of the eleven confirmed transient detections (boxes), ten are mergers of black holes and one is inspiral of neutron stars (bottom right). The heat map shows the energy in time and frequency for each of these cosmic events. The gravitational waves (yellow curves) are the predictions to Einstein’s general theory of relativity for the observed signal. The grey curves below them are a model-independent reconstruction of the signal recorded in LIGO. (Credit: Center for Relativistic Astrophysics)
