DOI: 10.1093/mnras/stad977
Abstract: Natal supernova kicks, the linear momentum compact remnants receive during their formation, are an essential part of binary population synthesis (BPS) models. Although these kicks are well-supported by evidence, their underlying distributions and incorporation into… read more here.

DOI: 10.1093/mnras/stx2123
Abstract: The cosmic merger rate density of black hole binaries (BHBs) can give us an essential clue to constraining the formation channels of BHBs, in light of current and forthcoming gravitational wave detections. Following a Monte… read more here.

DOI: 10.1093/mnras/sty339
Abstract: We obtain new and precise information on the double white dwarf (DWD) population and on its gravitational-wave-driven merger rate, by combining the constraints on the DWD population from two previous radial-velocity-variation studies: One based on… read more here.

DOI: 10.1103/physrevd.101.043015
Abstract: We derive a lower bound on the merger rate of primordial black hole (PBH) binaries by estimating the maximal fraction of binaries that were perturbed between formation in the early universe and merger, and computing… read more here.

DOI: 10.1103/physrevd.105.023004
Abstract: I investigate the roles of cluster dynamics and massive binary evolution in producing stellarremnant binary black hole (BBH) mergers over the cosmic time. To that end, dynamical BBH mergers are obtained from long-term direct N-body… read more here.

DOI: 10.1103/physrevd.105.043525
Abstract: We study the merger rate of primordial black holes (PBHs) in self-interacting dark matter (SIDM) halo models. To explore a numerical description of the density proļ¬le of SIDM halo models, we use the result of… read more here.
