CE is even considered by some as a mandatory phase in the formation of BH-BH, BH-NS or NS-NS mergers in binary evolution.

We find that the SN material fallback causes the convection-asymmetry kick to effectively retain similar number and mass of BHs in clusters as for the standard, momentum-conserving kick.

We use population synthesis simulations of isolated binary stars to explore some of the stellar physics that could be constrained with multiband events, and we show that specific formation pathways might be overrepresented in multiband events compared to ground-only detections.

We study the expected spin misalignments of merging binary black holes (BHs) formed in isolation by combining state-of-the-art population synthesis models with efficient post-Newtonian evolutions, thus tracking sources from stellar formation to gravitational-wave detection.
