Comme la plupart des galaxies massives, la Voie lactee heberge en son centre un trou noir supermassif. Contrairement aux noyaux actifs, celui-ci brille par la faiblesse de sa contrepartie radiative, la source Sgr A?, dont la luminosite est inferieure de pres de neuf ordres de grandeur a la luminosite limite d’Eddington. Plusieurs traces indirectes suggerent cependant que le trou noir galactique a connu des episodes d’activite plus intense dans le passe. La reflexion des rayons X emis lors des… Expand

Activité du trou noir supermassif au centre de la Galaxie
Le centre de la Galaxie abrite un trou noir supermassif, Sagittarius A*. Sa proximite en fait un laboratoire privilegie pour etudier les phenomenes d’accretion a l’œuvre autour des trous noirs etExpand

Examining molecular clouds in the Galactic Centre region using X-ray reflection spectra simulations
In the centre of our Galaxy lies a supermassive black hole, identified with the radio source Sagittarius A^⋆. This black hole has an estimated mass of around 4 million solar masses. AlthoughExpand
Echoes of multiple outbursts of Sagittarius A⋆ revealed by Chandra
Context. The relatively rapid spatial and temporal variability of the X-ray radiation from some molecular clouds near the Galactic center shows that this emission component is due to the reflectionExpand

Near-infrared flares from accreting gas around the supermassive black hole at the Galactic Centre
TLDR
High-resolution infrared observations of Sagittarius A* reveal ‘quiescent’ emission and several flares, and traces very energetic electrons or moderately hot gas within the innermost accretion region. Expand
X-ray Echo from the Sagittarius C Complex and 500-year Activity History of Sagittarius A*
This paper presents the Suzaku results obtained for the Sagittarius (Sgr) C region using the concept of X-ray reflection nebulae (XRNe) as the echo of past flares from the super massive black hole,Expand
The Origin of Diffuse X-Ray and γ-Ray Emission from the Galactic Center Region: Cosmic-Ray Particles
The inner couple of hundred parsecs of our Galaxy are characterized by a significant amount of synchrotron-emitting gas. Many of the best studied sources in this region exhibit a mixture of 6.4 keVExpand
Acceleration of petaelectronvolt protons in the Galactic Centre
TLDR
Deep γ-ray observations with arcminute angular resolution of the region surrounding the Galactic Centre are reported, which show the expected tracer of the presence of petaelectronvolt protons within the central 10 parsecs of the Galaxy, and it is proposed that the supermassive black hole Sagittarius A* is linked to this PeVatron.
