The preliminary detection of the Galactic Center black hole Sgr A* in X-rays by the Chandra mission, as well as recent mm-VLBI measurements, impose strict constraints on this source. Using a relativistic jet model for Sgr A*, we calculate the synchrotron and synchrotron self-Compton emission. The predicted spectrum provides an excellent fit to the radio spectrum and the the X-ray observations. Limits on the infrared flux and the low X-ray flux require a high-energy cut-off in the electron…

Jets in XRB Low/Hard States: Models of XTE J1118+480 Suggest a Strong Signature from Radio through X-Ray
Observations reveal the presence of powerful jets in the Low/Hard states of several black hole candidate X-ray binaries, so it is important to consider what signatures these outflows will have in the
AGNJET v2.0: Towards self-consistent MHD+RT jet models for XRBs and AGN
Collimated outflows are a common feature observed in many astrophysical systems including x-ray binaries (XRBs), active galactic nuclei (AGN), young stellar objects (YSOs) and gamma ray bursts
Properties of the radio-emitting gas around Sgr A*
We show that the radial profiles of the temperature and density of the electrons as well as the magnetic field strength around the massive black hole at the galactic centre, Sgr A*, may be
Simulating the emission and outflows from accretion discs
The radio source Sagittarius A* (Sgr A*) is believed to be a hot, inhomogeneous, magnetized plasma flowing near the event horizon of the 3.6 × 106 M⊙ black hole at the galactic centre. At a distance
Rapid X-ray flaring from the direction of the supermassive black hole at the Galactic Centre
TLDR
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.
Non-uniform model for the synchrotron radiation of Sgr A* and other low-luminosity galactic nuclei
A model for non-uniform source of synchrotron radiation with a power-law radial distribution of the magnetic field and relativistic-electron density along one-or two-sided jets is described.
Event-horizon-scale structure in the supermassive black hole candidate at the Galactic Centre
TLDR
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.
A new multiwavelength lepto-hadronic model of astrophysical jet emission
In the last few years, the rapid development of gamma-ray observations has open a new window on X-ray binaries (XRBs) sources. In this talk we introduce a new lepto-hadronic model that is based on
Towards the event horizon -- the supermassive black hole in the Galactic Center
The center of our Galaxy hosts the best constrained supermassive black hole in the universe, Sagittarius A* (Sgr A*). Its mass and distance have been accurately determined from stellar orbits and
Galactic X-ray binary jets
Abstract With their relatively fast variability time-scales, Galactic X-ray binaries provide an excellent laboratory to explore the physics of accretion and related phenomena, most notably outflows,
