The 6th Focus Workshop of the Center for the Gravitational-Wave Universe focuses on the Gravitational wave in astronomy and physics.

This workshop covers three following topics:

1- Electromagnetic follow-up Strategy (EM-GW):

 The recent discovery of gravitational waves (GWs) by the Advanced LIGO and VIRGO Observatories, sourced from the compact object mergers opened a new window in astronomy and cosmology. Transit gravitational waves which emit electromagnetic emissions can provide significant insights into the cosmic expansion history and rich physical context of cosmological and astrophysical phenomena. In this workshop, we focus on the concept and observing methods of Electromagnetic counterparts of gravitational wave sources.

2-  Systematics in Parameter Estimation (PE):

     For 90 gravitational waves observed so far, various physical and astronomical information of gravitational wave sources were obtained through parameter estimation. However, gravitational wave signals contain a lot of noise, and it is important to quickly get the  parameters with valid physical information in the noise. In this process, it is necessary to discuss the study of the systematic error caused by the waveform considering various physical effects, and it is also important to compare the results according to the pipeline used. In this workshop, we discuss an introduction to the most commonly used parameter estimation pipelines and the latest research results.

3- Prospects of GRB/Kilonova modeling:  

    The groundbreaking multi-messenger event, GW170817A, has opened a new window for broadening our understanding on the relativistic jet and the origin of heavy elements. In addition, the recent very-high-energy GRB afterglows have provided other pieces for completing the picture of the relativistic jet. To complete the broad, seamless picture of such events, the collaborative research and vigorous discussion are required, and this workshop meets such demands.  In this workshop, we will not only review on the latest results but also discuss the groundwork for pushing the frontiers of knowledge.
