Detectability of ringdown for high mass SMBH [1.0 yr]
FoM
Science investigation and Observational requirement: SI5.1 OR5.1 from Science requirement document.
Compute the maximum remnant mass \(M_{ m max}\) such that at least three RD modes are detectable with \(SNR>8\) at \(D_L=3 m Gpc\).
- OK 5.42 [1 5 10] : Detectability of ringdown for high mass SMBH
Capability to detect 3 ringdown modes of a source with mass > 5. 10^8 total mass
Summary
We use low frequency cutoff 2e-05 Hz, and merging MBHB binary of mass ratio 2.0 at redshift 0.5088612761824212 and using the SNR threshold 8.0
We should be able to detect at least three modes with:
- M_max > \(5.10^8\) (green)
- M_max > \(1.10^8\) (yellow)
-
M_max > \(10.10^8\) (blue)
-
The range of masses for 22 mode is [ 5.23e+04 - 5.42e+08 ] \(M_{\odot}\)
-
The range of masses for 33 mode is [ 1.00e+00 - 8.61e+08 ] \(M_{\odot}\)
-
The range of masses for 21 mode is [ 1.28e+05 - 4.76e+08 ] \(M_{\odot}\)
-
The range of masses for 44 mode is [ 1.00e+00 - 1.17e+09 ] \(M_{\odot}\)
