  1. Light and GW Emission from the First Detected BNS Merger

    Artist depict of a massive binary system (NASA). Overlaid: MESA evolutionary tracks LIGO Scientific Collaboration and Virgo Collaboration (LVC), PRL 2017 LVC+FERMI+… ApJL 2017 (MultiMessengerPaper)
  2. Artist depict of a massive binary system (NASA). Overlaid: MESA

    evolutionary tracks LIGO Scientific Collaboration and Virgo Collaboration (LVC), PRL 2017 Instrumental glitch in the Livingston detector data. Similar glitches are registered roughly once every few hours in each of the LIGO detectors with no temporal correlation between the LIGO sites. Their cause remains unknown.
