This page computes the closed-form chirp mass of the first directly detected binary black hole merger, GW150914, from its published component masses. It runs deterministically in your browser with no install, so a researcher can check the number directly before reaching for a cluster. GDBS is a bridge to HPC, not a replacement for it.
M_c = 28.72 solar masses vs LIGO 28.6 (0.4% agreement)
The closed-form chirp mass computed from the published component masses gives 28.72 solar masses against the LIGO value of 28.6 solar masses. Status: Verified - reproduced against the external published reference with no calibration.
The chirp mass is computed in closed form from the measured component masses:
M_c = (m1 m2)^(3/5) / (m1 + m2)^(1/5)
Evaluating this expression on the published GW150914 component masses yields 28.72 solar masses. The computation is deterministic and runs in-browser with no install.
This is the closed-form chirp mass from the measured component masses. The full matched-filter plus chi-squared plus ringdown pipeline is the separate LIGO analysis engine. This is a bridge to HPC, not a replacement for a production search.
Run the same closed-form computation yourself - deterministic, in your browser.
