Fermi-LAT Gravitational Waves Table

This page displays the outcomes of the Fermi-LAT automatic follow-up analysis pipeline used to search for electromagnetic counterparts of gravitational waves (GW). For a detailed explanation of the analysis techniques, please refer to 2017ApJ...841L..16V. Furthermore, the Fermi-LAT Collaboration has published additional papers on GW events such as GW150914, LVT151012 and GW151226, GW170104, and GW170817

All analysis results presented here should be considered preliminary, unless otherwise stated. If you have any questions, please write to Niccolò Di Lalla.

Table Legend

  • Trigger Name: LIGO-Virgo-KAGRA event name
  • Date: LIGO-Virgo-KAGRA event date
  • Time: LIGO-Virgo-KAGRA event time
  • GraceDB: LIGO-Virgo-KAGRA link to the GraceDB webpage
  • FAR [Hz]: LIGO-Virgo-KAGRA False Alarm Rate. Used to describe the significance of the event

  • Has Remnant?: LIGO-Virgo-KAGRA probability that the system ejected a non-zero amount of neutron star matter
  • FTI TS max: Fermi-LAT maximum value of the Test Statistic for the Fixed Time Interval analysis
  • ATI TS max: Fermi-LAT maximum value of the Test Statistic for the Adaptive Time Interval analysis
  • Flux UB [erg/cm2/s]: Fermi-LAT Bayesian flux Upper Bound at 95% of credibility interval for the fixed time interval analysis

Table Legend

  • Trigger Name: LIGO-Virgo-KAGRA event name
  • Date: LIGO-Virgo-KAGRA event date
  • Time: LIGO-Virgo-KAGRA event time
  • GraceDB: LIGO-Virgo-KAGRA link to the GraceDB webpage
  • FAR [Hz]: LIGO-Virgo-KAGRA False Alarm Rate. Used to describe the significance of the event
  • Highest Probability: LIGO-Virgo-KAGRA most probable source association. Can be BNS (binary neutron star), BBH (binary black hole), NSBH (neutron star black hole), Terrestrial (instrumental or environmental origin) or Burst (unmodeled event)
  • Has NS?: LIGO-Virgo-KAGRA probability that at least one of the compact objects was a neutron star'
  • Has Remnant?: LIGO-Virgo-KAGRA probability that the system ejected a non-zero amount of neutron star matter
  • Has MassGap?: LIGO-Virgo-KAGRA probability that at least one of the compact objects has mass in the range 3-5 solar masses
  • Inst. Coverage: Fermi-LAT coverage of the 90% LVK localization map at the GW trigger time
  • FTI TS max: Fermi-LAT maximum value of the Test Statistic for the Fixed Time Interval analysis
  • ATI TS max: Fermi-LAT maximum value of the Test Statistic for the Adaptive Time Interval analysis
  • Flux UB [erg/cm2/s]: Fermi-LAT Bayesian flux Upper Bound at 95% of credibility interval for the fixed time interval analysis
  • Analysis Report: Fermi-LAT link to the analysis report webpage
