The radio source Sagittarius A* in the Galactic center emits a polarized spectrum at millimeter and submillimeter wavelengths that is strongly suggestive of relativistic disk accretion onto a massive black hole. We use the well-constrained mass of Sgr A* and a magnetohydrodynamic model of the accretion flow to match both the total flux and polarization from this object. Our results demonstrate explicitly that the shift in the position angle of the polarization vector, seen at wavelengths near…

Resolved magnetic-field structure and variability near the event horizon of Sagittarius A*

Interferometric observations at 1.3-millimeter wavelength are reported that spatially resolve the linearly polarized emission from the Galactic Center supermassive black hole, Sagittarius A*.

Toward 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

An Accretion-induced X-Ray Flare in Sagittarius A*

The recent detection of a 3 hr X-ray flare from Sgr A* by Chandra provides very strong evidence for a compact emitting region near this supermassive black hole at the Galactic center. The

The Polarized Image of a Synchrotron-emitting Ring of Gas Orbiting a Black Hole

Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field in the emitting

Stochastic Acceleration in the Galactic Center HESS Source

Stochastic acceleration of electrons interacting resonantly with a turbulent magnetic field in a small accretion torus appears to be the likely mechanism responsible for much of Sagittarius A*'s

The linearly polarized millimeter and submillimeter emission in Sagittarius A* is produced within 10 Schwarzschild radii of the supermassive black hole at the Galactic center and may originate from a

The impact of Faraday effects on polarized black hole images of Sagittarius A

We study model images and polarization maps of Sagittarius A* at 230 GHz. We post-process GRMHD simulations and perform a fully relativistic radiative transfer calculation of the emitted synchrotron

Modulated X-Ray Emissivity near the Stress Edge in Sagittarius A*

Sgr A* is thought to be the radiative manifestation of a ~3.6 × 106 M☉ supermassive black hole at the Galactic center. Its millimeter/submillimeter spectrum and its flare emission at IR and X-ray

Decomposing the internal faraday rotation of black hole accretion flows

Electron Acceleration around the Supermassive Black Hole at the Galactic Center

The recent detection of variable infrared emission from Sagittarius A* combined with its previously observed flare activity in X-rays provide compelling evidence that at least a portion of this

The recent detection of significant linear polarization at millimeter and submillimeter wavelengths in the spectrum of Sagittarius A* (if confirmed) will be a useful probe of the conditions within

Sagittarius A* Polarization: No Advection-dominated Accretion Flow, Low Accretion Rate, and Nonthermal Synchrotron Emission

The recent detection of polarized radiation from Sgr A* requires a nonthermal electron distribution for the emitting plasma. The Faraday rotation measure must be small, placing strong limits on the

Explaining the spectrum of Sagittarius A* with a model of an accreting black hole

THE radio source at the centre of our Galaxy1, Sagittarius A* (Sgr A*), seems to be a low-luminosity version of active galactic nuclei—a massive black hole that is accreting gas from the surrounding

The effects of redshifts and focusing on the spectrum of an accretion disk around a Kerr black hole

The spectrum of X-rays produced by an accretion disk around a black hole is influenced markedly by Doppler shifts, gravitational redshifts, and the gravitational lens effect. These influences can be

Two possible explanations for the low luminosity of the supermassive black hole at the center of our Galaxy are (1) an accretion rate of the order of the canonical Bondi value (~10-5 M☉ yr-1) but a
