Signatures of Bulge Triaxiality from Kinematics in Baade's Window/

HongSheng Zhao, D. N. Spergel, R. M. Rich

We study a sample of 62 Baade's Window (1,-4) K giants that have published proper motions, radial velocity and metallicity. We construct the velocity ellipsoids for the metal rich…

Microlensing by the Galactic Bar

HongSheng Zhao, David N. Spergel, R. Michael Rich

We compute the predicted optical depth and duration distribution of microlensing events towards Baade's window in a model composed of a Galactic disk and a bar. The bar model is a…

Lick Optical Spectra of Quasar HS 1946+7658 at 10 km/sec Resolution: Lyman-Alpha Forest and Metal Absorption Systems

X. -M. Fan, D. Tytler

We present optical spectra of QSO HS~1946+7658 with either high resolution (FWHM=10 km/s) or high signal to noise ratio (SNR=40-100). We find 113 Lyman alpha and six metal line sys…
