Detecting intermediate mass ratio inspirals [1.0 yr]
FoM
Science investigation and Observational requirement: SI2.4 OR2.4b from Science requirement document.
Detection of MBHBs with source-frame primary mass in the range \(10^4-10^6\) M\(_\odot\), \(q=0.01\) and formation redshift in the range \(z = 2-3\) with SNR\(>30\).
- OK 89.41016594118838 [50 75 90] : SO2 Detecting intermediate mass ratio inspirals
Assuming detection threshold 30. Detectability is OK if probability of detection > %75
Summary
MBHB with waveform IMRPhenomHM of
- mass in 1.000000e+04-1.000000e+06 solar mass (log uniform)
- mass ratio in [100] (log uniform),
- redshift in [2, 3] (uniform in comoving volume)
- t0 in [0.10 - 0.95] (uniform)
- chi in [0.00 - 0.99] (uniform))
Conducting monte-carlo over 10000 trials, randomizing spins, sky position and orientation
Assuming SNR threshold for detection: 30.0
