The last few years have produced large and rapid advances in our understanding of the galactic center. New information has come via a variety of methods, including high spatial resolution radio and infrared continuum mapping, and line observations in the micron through centimeter wavelength range.

The innermost central part of the Galaxy has very complicated morphology and kinematics. We make an emphasis on the dynamical nature of the ‘mini-spiral’. Two cases are considered: (i) the putative black hole lies at the center of the dense stellar cluster and (ii) it is off the center.

This chapter examines the next four novels in Gregory Benford's Galactic Center series: Great Sky River (1987), Tides of Light (1989), Furious Gulf (1992), and Sailing Bright Eternity (1995). The novels span vast expanses of spacetime and nine years of Benford's career.

The supermassive black-hole in the center of the Milky Way, located in the radio source Sgr A*, is one of the most interesting astronomical objects (see [126] for an extensive review). It is now in a state of relative inactivity [201] but it might well be a non-stationary source. For instance, there are interesting hints of a much stronger emission few

Massive stars in the galactic center
New Astronomy Reviews, 2000We review quantitative spectroscopic studies of massive stars in the Galactic Center clusters. Thanks to the impressive evolution of IR detectors an the new generation of line blanketed models for the extended atmospheres of hot stars we are able to accurately derive the physical properties of the massive stars in these clusters.
