Dynamical Mechanism of Episodic Gas Accretion to the Central Region of Spiral Galaxies

The Astrophysical Journal
We performed N -body/smoothed particle hydrodynamics simulations of isolated spiral galaxies with various bulge-to-disk mass ratios ( M _bulge / M _disk ) from 0.02 to 0.2 to investigate mass transport from galactic scales (10 kpc) down to circumnuclear ...

Technetium in Galactic Bulge AGB Stars

, 2007
Technetium has been of high interest in AGB studies for many decades due to its radioactive nature. Here we report on observations of technetium in galactic bulge AGB variables. ..

Kinematics and stellar populations of the galactic bulge.

, 1993
In order to measure radial and/or rotation velocities and obtain metallicities for the stellar population of the Galactic bulge, several hundred spectra of giants have been obtained.
