On the microlensing optical depth of the Galactic bar
On the microlensing optical depth of the Galactic bar
The microlensing probability (optical depth τ) towards the Galactic Centre carries information about the mass distribution of the Galatic bulge/bar, and so it can be used to constrain the very uncertain shape parameters of the bar. We find τ depends on the bar mass, radial profile, angle, axis scalelengths and …
