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 ...

Microlensing Discovery and Characterization Efficiency in the Vera C. Rubin Legacy Survey of Space and Time

The Astrophysical Journal Supplement Series
The Vera C. Rubin Legacy Survey of Space and Time will discover thousands of microlensing events across the Milky Way, allowing for the study of populations of exoplanets, stars, and compact objects.

Dynamical Origin of the Vertical Metallicity Gradient of the Milky Way Bulge

The Astrophysical Journal
A vertical metallicity gradient (VMG) in the Milky Way bulge is well-established. Yet, its origin has not been fully understood under the Galactic secular evolution scenario.
