We review our current understanding to the accretion and ejection processes in Sgr A*. Roughly speaking, they correspond to the quiescent and flare states of the source respectively. The high-resolution {\it Chandra} observations to the gas at the Bondi radius combined with the Bondi accretion theory, the spectral energy distribution from radio to X-ray, and the radio polarization provide us strict constraints and abundant information to the theory of accretion. We review these observational…

Extreme warm absorber variability in the Seyfert galaxy Mrk 704
Context. In about half of Seyfert galaxies, the X-ray emission is absorbed by an optically thin, ionized medium, the so-called “Warm Absorber”, whose origin and location is still a matter of debate.
A self-consistent hybrid Comptonization model for broad-band spectra of accreting supermassive black holes
The nature of the broad-band spectra of supermassive accreting black holes in active galactic nuclei (AGNs) is still unknown. The hard X-ray spectra of Seyferts as well as of Galactic stellar-mass
An overview of the high-energy emission from the Galactic Center
The Galactic Center is a prominent source in X-rays and gamma-rays and the study of its high-energy emission is crucial in understanding the physical phenomena taking place in its dense and extreme
Detection of Microvariability in a New Class of Blazar-Like AGN
Recent research has lead to the possible discovery of a new class of gamma-ray emitting active galactic nuclei (AGN). These objects – the very radio-loud narrow-line Seyfert 1 galaxies (NLSy1s)–
SDSS J143244.91+301435.3: a link between radio-loud narrow-line Seyfert 1 galaxies and compact steep-spectrum radio sources?
We present SDSSJ143244.91+301435.3, a new case of radio-loud narrow line Seyfert 1 (RL NLS1) with a relatively high radio power (P1.4GHz=2.1x10^25 W Hz^-1) and large radioloudness parameter
