Nonnegligible mismodeling of astrophysical backgrounds and foregrounds may affect the details on the prediction for such unresolved population of point sources within the
galactic bulge; see, e.g., [261].
In this work, the total potential [[PHI].sub.T] is composed by three components, representing the
galactic bulge, disk and bar:
This should ultimately lead to a more precise estimate of the age of the
galactic bulge. They might also determine if star formation processes in the bulge billions of years ago were different from what's seen in the younger disk of our galaxy.
Remarkably, there is a strong correlation between the mass of the SMBH and that of the
galactic bulge (or its luminosity, or stellar velocity-dispersion) over a wide range of the mass.
A study result shows that the mass of a supermassive black hole is approximately proportional to that of the central part of the galaxy (
galactic bulge).
New details are emerging about the structure of the
galactic bulge surrounding the black hole core.
Microlensing events detected by the OGLE or MOA groups in the
galactic bulge are studied for caustic behaviour in the microlensing lightcurve to detect the presence of planets around the lens star.
Among the topics are the evolution and nucleo-synthesis of extremely metal-poor AGB stars, the second release of the Torun Catalogue of galactic post-AGB stars, double chemistry in
galactic bulge planetary nebulae, and the role of AGB stars in the global gas and dust budget of the Large Magellanic cloud.
Generally, the black hole's mass was seen to be about 1,000th that of the mass of the surrounding
galactic bulge.
Specific topics covered include the UV spectrum of the
galactic bulge, helium and the hot horizontal branch, binary population synthesis and sdB stars at different metallicities, and hypervelocity stars.
