predictions with the LIGO observational results.

Left: Redshifted total merger mass distribution for models M10
(red) and M23 (magenta). The O2 LIGO sensitivity is marked; the most
likely detections are expected when models are closest to the sensitivity
curve. We also mark LIGO/Virgo BH-BH merger detections (vertical
positions have no meaning), all of which fall within the most likely
detection region: M_{tot,z} ∼ 20–100 M_{sun}

Right: Source frame BH-BH merger-rate density of our models for the local Universe (z = 0). The
current LIGO O1/O2 BH-BH merger rate is 12–213 Gpc^{−3} yr^{−1}
(blue double-headed arrow). Note that our models with fallback-attenuated
BH natal kicks (M10, M20) are at the LIGO upper limit, while our
models with high BH natal kicks are at the LIGO lower limit (M13,
M23). Models with small (M26) and intermediate (M25) BH kicks fall
near the middle of the LIGO estimate.

This website will be kept updated with new models and observations as they
appear.
