The high velocity gradient observed in the compact cloud CO-0.40-0.22, at a projected distance of 60 pc from the centre of the Milky Way, has led its discoverers to identify the closeby mm continuum emitter, CO-0.40-0.22*, with an intermediate mass black hole (IMBH) candidate. We describe the interaction between CO-0.40-0.22 and the IMBH, by means of a simple analytical model and of hydrodynamical simulations. Through such calculation, we obtain a lower limit to the mass of CO-0.40-0.22* of few… Expand

The Fifth Candidate for an Intermediate-mass Black Hole in the Galactic Center
We report the results of high-resolution molecular line observations of the high-velocity compact cloud HCN-0.085-0.094 with the Atacama Large Millimeter/submillimeter Array. The HCN J=4-3, HCO$^+$Expand
An energetic high-velocity compact cloud: CO−0.31+0.11
We have discovered an energetic high-velocity compact cloud CO$\, -0.31+$0.11 in the central molecular zone of our Galaxy. CO$\, -0.31+$0.11 is located at a projected distance of ∼45 pc from theExpand
Indication of Another Intermediate-mass Black Hole in the Galactic Center
We report the discovery of molecular gas streams orbiting around an invisible massive object in the central region of our Galaxy, based on the high-resolution molecular line observations with theExpand
Light, medium-weight, or heavy? The nature of the first supermassive black hole seeds
Observations of hyper-luminous quasars at z > 6 reveal the rapid growth of supermassive black holes (SMBHs > 109M ) whose origin is still difficult to explain. Their progenitors may have formed asExpand
Resonant Dynamical Friction in Nuclear Star Clusters: Rapid Alignment of an Intermediate-mass Black Hole with a Stellar Disk
We investigate the dynamical evolution of an intermediate-mass black hole (IMBH) in a nuclear star cluster hosting a supermassive black hole (SMBH) and both a spherical and a flattened disk-likeExpand
Unique Multimessenger Signal of QCD Axion Dark Matter.
The projected reach of the LISA interferometer and next-generation radio telescopes such as the Square Kilometre Array is studied to infer the dark matter density and, consequently, to predict the radio emission. Expand


Signature of an Intermediate-Mass Black Hole in the Central Molecular Zone of Our Galaxy
We mapped the high-velocity compact cloud CO-0.40-0.22 in 21 molecular lines in the 3 mm band using the Nobeyama Radio Observatory 45 m radio telescope. Eighteen lines were detected fromExpand
La Freccia Rossa: an IR-dark cloud hosting the Milky Way intermediate-mass black hole candidate
The dynamics of the high-velocity compact molecular cloud CO-0.40-0.22 have been interpreted as evidence for a ∼10^5 M_⊙ black hole within 60 pc of Sgr A*. Recently, Oka et al. have identified aExpand
Gemini and Hubble Space Telescope Evidence for an Intermediate-Mass Black Hole in ω Centauri
The globular cluster ω Centauri is one of the largest and most massive members of the galactic system. However, its classification as a globular cluster has been challenged making it a candidate forExpand
Mass models of NGC 6624 without an intermediate-mass black hole
An intermediate-mass black hole (IMBH) was recently reported to reside in the centre of the Galactic globular cluster (GC) NGC 6624, based on timing observations of a millisecond pulsar (MSP) locatedExpand
A Black Hole in the Galactic Center Complex IRS 13E
The IRS 13E complex is an unusual concentration of massive, early-type stars at a projected distance of ~0.13 pc from the Milky Way's central supermassive black hole Sagittarius A* (Sgr A*). BecauseExpand
The nuclear cluster of the Milky Way: total mass and luminosity
Like many other late-type galaxies, the Milky Way contains a nuclear star cluster. In this work we obtain the basic properties of its dominant old stellar population. Firstly, we derive itsExpand
Millimetre-wave emission from an intermediate-mass black hole candidate in the Milky Way
It is widely accepted that black holes with masses greater than a million solar masses (M⊙) lurk at the centres of massive galaxies. The origins of such ‘supermassive’ black holes (SMBHs) remainExpand
Re-evaluation of the central velocity-dispersion profile in NGC 6388
Context. The globular cluster NGC 6388 is one of the most massive clusters in our Milky Way and has been the subject of many studies. Recently, two independent groups found very different resultsExpand
Very large telescope kinematics for omega Centauri: Further support for a central black hole
The Galactic globular cluster. Centauri is a prime candidate for hosting an intermediate- mass black hole. Recent measurements lead to contradictory conclusions on this issue. We use VLT- FLAMES toExpand
