Project Description

Scientific goals

• To search for scalar gravitational wave signals in scalar-tensor theory using data from a network of detectors. Set upper limits in the absence of the detection.
• To constrain gravity theory in strong gravity field.
• To understand how to optimally use network analysis methods with real data for the gravitational wave tests.

Data sets

• S5 and S6.

Analysis approach

• Coherent network analysis.
• Input data: h(t)
• Output
  • reconstructed time series for h+(t), hx(t), ho(t)
  • Background analysis on reconstructed ho(t)
  • auxiliary outputs, such as estimates of line amplitudes and phases, that can be helpful for diagnostics
