Sagittarius A$^*$ in the Galactic center harbors a supermassive black hole and exhibits various active phenomena. Besides quiescent emission in radio and submillimeter radiation, flares in the near infrared (NIR) and X-ray bands are observed to occur frequently. We study a time-dependent model of the flares, assuming that the emission is from a blob ejected from the central object. Electrons obeying a power law with the exponential cutoff are assumed to be injected in the blob for a limited…

An inverse Compton scattering origin of x-ray flares from Sgr A
The X-ray and near-IR emission from Sgr A* is dominated by flaring, while a quiescent component dominates the emission at radio and submillimeter (sub-mm) wavelengths. The spectral energy
A Leptonic Model of Steady High-Energy Gamma-Ray Emission from Sgr A$^*$
Recent observations of Sgr A* by Fermi and HESS have detected steady {gamma}-ray emission in the GeV and TeV bands. We present a new model to explain the GeV {gamma}-ray emission by inverse Compton

Aims. The radiative counterpart of the supermassive black hole at the Galactic center (GC), Sgr A � , is subject to frequent flares that are visible simultaneously in X-rays and the near-infrared
X-Ray Flares from Sagittarius A * and Black Hole Universe
Sagittarius (Sgr) A* is a massive black hole at the Milky Way center with mass of about 4.5 million solar masses. It is usually quite faint, emiting steadily at all wavelengths including X-rays.
Statistical and theoretical studies of flares from Sagittarius A⋆
Abstract Multi-wavelength flares have routinely been observed from the supermassive black hole, Sagittarius A⋆ (Sgr A⋆), at our Galactic center. The nature of these flares remains largely unclear,

The accretion flow around the Galactic Center black hole Sagittarius A* (Sgr A*) is expected to have an electron temperature that is distinct from the ion temperature, due to weak Coulomb coupling in
Sgr A* flares: Tidal disruption of asteroids and planets?
It is speculated that one such disruption may explain the putative increase in Sgr A ∗ luminosity, and is estimated that asteroids larger than ∼10 km in size are needed to power the observed flares, with the maximum possible luminosity of the order of 10 39 erg s −1.
