The Galaxy Center in X-rays At the center of our Galaxy there is a black hole 4-million-fold more massive than the Sun. Wang et al. (p. 981; see the Perspective by Schnittman) report x-ray data on the accretion flow around this supermassive black hole, revealing how it interacts with its surroundings. The data rule out the possibility that the quiescent (that is, flare-free) x-rays observed are produced by coronal emission from a population of stars at the center of the Galaxy and also rule out… 

The quiescent X-ray spectrum of accreting black holes

The quiescent state is the dominant accretion mode for black holes on all mass scales. Our knowledge of the X-ray spectrum is limited due to the characteristic low luminosity in this state. Herein,

The Curious Behavior of the Milky Way's Central Black Hole

X-ray observations of the supermassive black hole at the galactic center help explain the unusually inefficient accretion of surrounding gas, and help constrain some of the leading theoretical models for the behavior of material accreting onto the giant black hole.

The multiwavelength spectrum of NGC 3115: hot accretion flow properties

NGC 3115 is the nearest galaxy hosting a billion solar mass black hole and is also a low-luminosity active galactic nucleus (LLAGN). X-ray observations of this LLAGN are able to spatially resolve the

The high SNR rate in the Galactic Center: origin of the cosmic rays excess?

Abstract The center of our Galaxy hosts a Super-Massive Black Hole (SMBH) of about 4 × 106 M⊙. Since it has been argued that the SMBH might accelerate particles up to very high energies, its current

Cosmic rays from the nearby starburst galaxy NGC 253: the effect of a low-luminosity active galactic nucleus

NGC 253 is a nearby starburst galaxy in the Sculptor group located at a distance of 3.5 Mpc that has been suggested by some authors as a potential site for cosmic-ray acceleration up to ultra-high

An X-ray chimney extending hundreds of parsecs above and below the Galactic Centre

It is proposed that huge X-ray structures extending hundreds of parsecs above and below the Galactic plane constitute exhaust channels through which energy and mass, injected by a quasi-continuous train of episodic events at the Galactic Centre, are transported from the central few parsecS to the base of the Fermi bubbles.

Modelling the thermal X-ray emission around the Galactic centre from colliding Wolf-Rayet winds

Abstract The Galactic centre is a hotbed of astrophysical activity, with the injection of wind material from ~30 massive Wolf-Rayet (WR) stars orbiting within 12″ of the super-massive black hole

Stellar winds near massive black holes – the case of the S-stars

The Galactic center provides a unique laboratory to study the interaction of a supermassive black hole (SMBH) with its gaseous and stellar environment. Simulations to determine the accretion of

An energetic hot wind from the low-luminosity active galactic nucleus M81*

For most of their lifetime, super-massive black holes (SMBHs) commonly found in galactic nuclei obtain mass from the ambient medium at a rate well below the Eddington limit1, which is mediated by a

UNIVERSAL BEHAVIOR OF X-RAY FLARES FROM BLACK HOLE SYSTEMS

X-ray flares have been discovered in black hole systems such as gamma-ray bursts, the tidal disruption event Swift J1644+57, the supermassive black hole Sagittarius A* at the center of our Galaxy,

Rapid X-ray flaring from the direction of the supermassive black hole at the Galactic Centre

The discovery of rapid X-ray flaring from the direction of Sagittarius A* provides compelling evidence that the emission is coming from the accretion of gas onto a supermassive black hole at the Galactic Centre.

Viewing the Shadow of the Black Hole at the Galactic Center

There exists a realistic expectation of imaging the event horizon of a black hole within the next few years, and it is shown that the shadow of Sgr A* may be observable with very long baseline interferometry at submillimeter wavelengths, assuming that the accretion flow is optically thin in this region of the spectrum.

Event-horizon-scale structure in the supermassive black hole candidate at the Galactic Centre

Observations at a wavelength of 1.3 mm set a size of microarcseconds on the intrinsic diameter of Sagittarius A*, suggesting that the bulk of Sgr A* emission may not be centred on the black hole, but arises in the surrounding accretion flow.

FADING HARD X-RAY EMISSION FROM THE GALACTIC CENTER MOLECULAR CLOUD Sgr B2

The observation of a clear decay of the hard X-ray emission from the molecular cloud Sgr B2 during the past seven years is reported, thanks to more than 20 Ms of INTEGRAL exposure, and it is found that the period of intense activity of Sgr A* ended between 75 and 155 years ago.

Non-Thermal Insights on Mass and Energy Flows Through the Galactic Centre and into the Fermi Bubbles

We construct a simple model of the star-formation- (and resultant supernova-) driven mass and energy flows through the inner ∼200 pc (in diameter) of the Galaxy. Our modelling is constrained, in

Bondi flow from a slowly rotating hot atmosphere

A supermassive black hole in the nucleus of an elliptical galaxy at the centre of a cool-core group or cluster of galaxies is immersed in hot gas. Bondi accretion should occur at a rate determined by

What Is the Accretion Rate in Sagittarius A*?

The radio source Sagittarius A* at the center of our Galaxy is believed to be a 2.6×106 M black hole that accretes gas from the winds of nearby stars. We show that limits on the X-ray and infrared
