I was running a PyCBC simulation of black hole mergers and I found a very peculiar question. When I was simulating two black holes colliding I observed that the peak positive amplitude of the merger varies sometimes. It should intuitively increase with the increase of mass but for some masses, it decreases.
I have plotted a scatter plot of these amplitudes y-Axis - Amplitude x-Axis - Mass M1 Assuming Mass m2 is kept constant at 10 solar masses
Frequency is 60hz
sample rate is 1/4096
spinz is 0.1
The y-axis is in the order of 10-19
Why does this Happen?
