... We compare our results with the GRANAT X-ray observations of the Galactic center (Churazov et al. ... It is instructive to compare our results for the Galactic center starburst with what might be expected for a continuous star formation, with the average rate characteristic for the whole Galaxy. For this continuous star formation model, we would expect to observe in the region of around the Galactic center about 10% of the total number of X-ray sources in the Galaxy. ...

Small Galaxy Groups ASP Conference Series, Vol. ... It is generally accepted that they are related to the nuclear rings formed in barred galaxies at the inner Linblad resonance (ILR), although according to Buta and Crocker (1993), in some cases they were found in non-barred spirals, so in general a presence of large-scale non-axisymmetric gravitational potential is not a rigid condition for the nuclear bar to be formed. Typical length of nuclear bars is 1 - 2 kpc for H 0 = 75km=s=Mpc. ...
