Binary neutron-star mergers will predominantly produce black-hole remnants of mass ∼ 3 – 4     M ⊙ , thus populating the putative low-mass gap between neutron stars and stellar-mass black holes. If these low-mass black holes are in dense astrophysical environments, mass segregation could lead to “second-generation” compact binaries merging within a Hubble time. In this paper, we investigate possible signatures of such low-mass compact binary mergers in gravitational-wave observations. We show…

Black hole - neutron star mergers: the first mass gap and kilonovae
Observations of X-ray binaries indicate a dearth of compact objects in the mass range from $\sim 2-5$ $M_{\odot}$ and the existence of this (first mass) gap has been used to advance our understanding
Exploring the Lower Mass Gap and Unequal Mass Regime in Compact Binary Evolution
On August 14, 2019, the LIGO and Virgo detectors observed GW190814, a gravitational-wave signal originating from the merger of a $\simeq 23 M_\odot$ black hole with a $\simeq 2.6 M_\odot$ compact
Outliers in the LIGO black hole mass function from coagulation in dense clusters
The advanced LIGO O3a run catalogue has been recently published, and it includes several events with unexpected mass properties, including mergers with individual masses in the lower and upper mass
GW190814: Gravitational Waves from the Coalescence of a 23 Solar Mass Black Hole with a 2.6 Solar Mass Compact Object
We report the observation of a compact binary coalescence involving a 22.2–24.3 M ⊙ black hole and a compact object with a mass of 2.50–2.67 M ⊙ (all measurements quoted at the 90% credible level).

Stochastic Gravitational-Wave Backgrounds: Current Detection Efforts and Future Prospects
The collection of individually resolvable gravitational wave (GW) events makes up a tiny fraction of all GW signals that reach our detectors, while most lie below the confusion limit and are
Black holes merging with low mass gap objects inside globular clusters
Recently, the LIGO-Virgo collaborations have reported the coalescence of a binary involving a black hole and a low-mass gap object (LMGO) with mass in the range ∼ 2.5−5M . Such detections, challenge

Post-Newtonian Dynamics in Dense Star Clusters: Highly Eccentric, Highly Spinning, and Repeated Binary Black Hole Mergers.
Modelling the relativistic accelerations and gravitational-wave emission in isolated binaries and during three- and four-body encounters finds that nearly half of all binary black hole mergers occur inside the cluster, with about 10% of those mergers entering the LIGO/Virgo band with eccentricities greater than 0.1.

On the black hole from merging binary neutron stars: how fast can it spin?
The merger of two neutron stars will in general lead to the formation of a torus surrounding a black hole whose rotational energy can be tapped to potentially power a short gamma-ray burst. We have
We use dynamical mass measurements of 16 black holes in transient low-mass X-ray binaries to infer the stellar black hole mass distribution in the parent population. We find that the observations are

Distinguishing types of compact-object binaries using the gravitational-wave signatures of their mergers
This work considers population-synthesis predictions for plausible merging binary distributions in mass space, along with measurement accuracy estimates from the main gravitational-wave parameter-estimation pipeline, and finds that for the model compact-object binary mass distribution, it can always distinguish binary neutron stars and black-hole--neutron-star binaries.
