The interaction between a supermassive black hole (SMBH) and the surrounding material is of primary importance in modern astrophysics. The detection of the molecular 2 pc circumnuclear disk (CND) immediately around the Milky Way SMBH, SgrA*, provides a unique opportunity to study SMBH accretion at subparsec scales. Our new wide-field CS(J = 2 − 1) map toward the Galactic center (GC) reveals multiple dense molecular streamers that originated from the ambient clouds 20 pc further out, and that… 

The Nuclear Filaments inside the Circumnuclear Disk in the Central 0.5 pc of the Galactic Center

We present CS(7–6) line maps toward the central parsec of the Galactic center, conducted with the Atacama Large Millimeter/submillimeter Array. The primary goal is to find and characterize the gas

The Circumnuclear Disk Revealed by ALMA. I. Dense Clouds and Tides in the Galactic Center

Utilizing the Atacama Large Millimeter/submillimeter Array, we present CS line maps in five rotational lines (J u = 7, 5, 4, 3, 2) toward the circumnuclear disk (CND) and streamers of the Galactic

High-speed molecular cloudlets around the Galactic center's supermassive black hole.

It is shown that molecular cloudlets, all together with a mass of several 10 M ⊙, exist around Sgr A*.

Time evolution simulations for the galactic centre circumnuclear disc

The supermassive black hole at the Galactic Centre is surrounded by the so-called Circumnuclear Disc (CND) with a sharp inner edge at 1.5 pc. Both its outer extent and the total mass contained within

Tidally-disrupted Molecular Clouds falling to the Galactic Center

Abstract We found a molecular cloud connecting from the outer region to the “Galactic Center Mini-spiral (GCMS)” which is a bundle of the ionized gas streams adjacent to Sgr A*. The molecular cloud

Effects of Turbulence in the Circumnuclear Disk

A circumnuclear disk (CND) of molecular gas occupies the central few parsecs of the Galactic Center. It is likely subject to turbulent disruptions from violent events in its surrounding environment,

Feeding of active galactic nuclei by dynamical perturbations

There possibly was an active galactic nuclei (AGN) episode in the Galactic Centre (GC) about 6 Myr ago, powerful enough to produce the Fermi bubbles. We present numerical simulations of a possible

Simulations of the Milky Way’s central molecular zone – I. Gas dynamics

We use hydrodynamical simulations to study the Milky Way's central molecular zone (CMZ), i.e. the star-forming nuclear ring at Galactocentric radii $R\lesssim200$ pc. The simulations comprise the gas

A Magnetic Field Connecting the Galactic Center Circumnuclear Disk with Streamers and Mini-spiral: Implications from 850 μm Polarization Data

Utilizing James Clark Maxwell Telescope 850 μm SCUPOL dust polarization data, we investigate the configuration of the magnetic (B) field in the circumnuclear disk (CND) of the Galactic center. The

Observational constraints on the feeding of supermassive black holes

Supermassive black holes grow at the centre of galaxies in consonance with them. In this Review Article, we discuss the mass-feeding mechanisms that lead to this growth in active galactic nuclei




The supermassive black hole (SMBH), Sgr A*, at the Galactic center is surrounded by a molecular circumnuclear disk (CND) lying between 1.5 and 4 pc radii. The irregular and clumpy structures of the

The interstellar region within the few central parsecs around the super-massive black hole, Sgr A* at the very Galactic center is composed by a number of overlapping molecular structures which are

Chemical features in the circumnuclear disk of the Galactic center

Aims. The circumnuclear disk (CND) of the Galactic center is exposed to many energetic phenomena coming from the supermassive black hole Sgr A* and from stellar activities. These energetic activities

Modelling the formation of the circumnuclear ring in the Galactic centre

Several thousand solar masses of molecular, atomic and ionized gas lie in the innermost ~10 pc of our Galaxy. The most relevant structure of molecular gas is the circumnuclear ring (CNR), a dense and
