We compute a microlensing map for the Galactic bar. The predicted event rate and event duration distribution are consistent with the 55 events recently reported by the MACHO and OGLE collaborations. Most of the events are due to lensing by stars in the near end of the bar_ Lens mass functions with about 30-60 per cent of the lens mass as brown dwarfs are rejected at 20'-60' levels_ To make our model useful for other workers, we tabulate the optical depth of the bar and average event duration…

On Microlensing Event Rates and Optical Depth toward the Galactic Center

The dependence of microlensing timescale frequency distributions and optical depth toward the Galactic center on Galactic model parameters is explored in detail for a distribution of stars consisting

Gravitational Microlensing and the Structure of the Inner Milky Way

We analyze the first-year MACHO collaboration observations of microlensing toward the Galactic center using a new direct likelihood technique that is sensitive to the distribution of the events on

Microlensing Maps for the Milky Way Galaxy

At any instant, there are ~1000 microlensing events to sources brighter than 20 mag in the Milky Way. Large-scale maps of the microlensing optical depth and the mean timescale are constructed for a

Microlensing constraints on the Galactic bulge initial mass function

Aims. We seek to probe the Galactic bulge IMF starting from microlensing observations. Methods. We analyse the recent results of the microlensing campaigns carried out towards the Galactic bulge

The Initial Mass Function of the Inner Galaxy Measured from OGLE-III Microlensing Timescales

We use the timescale distribution of ∼3000 microlensing events measured by the OGLE-III survey, together with accurate new made-to-measure dynamical models of the Galactic bulge/bar region, to

Large-Scale Model of the Milky Way: Stellar Kinematics and the Microlensing Event Timescale Distribution in the Galactic Bulge

We build a stellar-dynamical model of the Milky Way's barred bulge and disk, using a newly implemented adaptive particle method. The underlying mass model has been previously shown to match the

An Inner Ring and the Microlensing toward the Bulge

All current bulge-disk models for the inner Galaxy fall short of reproducing self-consistently the observed microlensing optical depth by a factor of 2 (>2 σ). We show that the least mass-consuming

Rates for Parallax-shifted Microlensing Events from Ground-based Observations of the Galactic Bulge

The parallax effect in ground-based microlensing (ML) observations consists of a distortion to the standard ML light curve arising from the Earth's orbital motion. This can be used to partially

A new model for the Milky Way bar

Abstract We use Schwarzschild's orbit-superposition technique to construct self-consistent models of the Galactic bar. Using χ2 minimisation, we find that the best-fit Galactic bar model has a

Microlensing Optical Depth Revisited with Recent Star Counts

More reliable constraints on the microlensing optical depth can come from a better understanding of the Galactic model. Based on well-constrained Galactic bulge and disk models constructed from
