Constraining the progenitors of luminous quasars at the peak of quasar activity (new OR low freq) [1.0 yr]
FoM
Science investigation and Observational requirement: new OR from low frequency study.
Detection of MBHBs with source-frame mass in the range \(10^7-10^8\) M\(_\odot\) and formation redshift in the range \(z = 2.5-3.5\) with SNR\(>10\).
- GREAT 99.0718286777604 [50 75 90] : SO2 Constraining the progenitors of luminous quasars at the peak of quasar activity (new OR low freq)
Assuming detection threshold 50. Detectability is OK if probability of detection > %75
Summary
MBHB with waveform IMRPhenomHM of
- mass in 1.000000e+07-1.000000e+08 solar mass (log uniform)
- mass ratio in [1, 10] (log uniform),
- redshift in [2.5, 3.5] (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: 50.0
