Context. The next generation of gravitational wave (GW) observatories would enable the detection of intermediate-mass black holes (IMBHs), an elusive type of BH expected to reside in the centres of massive clusters, dwarf galaxies, and possibly the accretion discs of active galactic nuclei. Intermediate-mass ratio inspirals (IMRIs), which are composed of an IMBH and a compact stellar object, constitute one promising source of GWs detectable by this new generation of instruments. Aims. We study… 
Merger Rates of Intermediate-mass Black Hole Binaries in Nuclear Star Clusters
Repeated mergers of stellar-mass black holes in dense star clusters can produce intermediate-mass black holes (IMBHs). In particular, nuclear star clusters at the centers of galaxies have deep enough
Hunting for intermediate-mass black holes with LISA binary radial velocity measurements
Despite their potential role as massive seeds for quasars, in dwarf galaxy feedback, and in tidal disruption events, the observational evidence for intermediate-mass black holes (IMBHs) is scarce.
Breaching the Limit: Formation of GW190521-like and IMBH Mergers in Young Massive Clusters
The LIGO-Virgo-Kagra Collaboration (LVC) discovered recently GW190521, a gravitational wave (GW) source associated with the merger between two black holes (BHs) with mass 66 and >85 M ⊙. GW190521


Intermediate-mass Black Holes from High Massive-star Binary Fractions in Young Star Clusters
Black holes formed in dense star clusters, where dynamical interactions are frequent, may have fundamentally different properties than those formed through isolated stellar evolution. Theoretical
GW190521 May Be an Intermediate-mass Ratio Inspiral
GW190521 is the first confident observation of a binary black hole merger with total mass . Given the lack of observational constraints at these masses, we analyze GW190521 considering two different
GW190521: A Binary Black Hole Merger with a Total Mass of 150  M_{⊙}.
It is inferred that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65  M⊙, which can be considered an intermediate mass black hole (IMBH).
Intermediate mass black hole formation in compact young massive star clusters
Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carried out with
Intermediate-Mass Black Holes
We describe ongoing searches for intermediate-mass black holes with M_BH ~ 100-10^5 M_sun. We review a range of search mechanisms, both dynamical and those that rely on accretion signatures. We find
Evidence of Nonluminous Matter in the Center of M62
Theoretical models suggest that intermediate-mass black holes (IMBHs) may form and reside in the centers of globular clusters. IMBHs are still elusive to observations, but the accelerations of
The missing link in gravitational-wave astronomy: discoveries waiting in the decihertz range
The gravitational-wave astronomical revolution began in 2015 with LIGO’s observation of the coalescence of two stellar-mass black holes. Over the coming decades, ground-based detectors like laser
Intermediate mass black holes in globular clusters: effects on jerks and jounces of millisecond pulsars
Globular clusters may host intermediate mass black holes (IMBHs) at their centres. Here we propose a new method for their identification using millisecond pulsars (MSPs) as probes. We show that
The Japanese space gravitational wave antenna: DECIGO
The objectives of the DECi-hertz Interferometer Gravitational Wave Observatory (DECIGO) are to open a new window of observation for gravitational wave astronomy and to obtain insight into significant
