The Optical Gravitational Lensing Experiment. Follow-Up Observations of the Macho Microlensing Event in the Galactic Bulge
M. Szymanski, A. Udalski, J. Kaluzny +3
We present follow-up observations of a gravitational microlensing candidate found by the MACHO collaboration in the Galactic bulge. The photometric data cover a period near the max…
The Optical Gravitational Lensing Experiment. Variable stars in the Sculptor dwarf speroidal galaxy
J. Kaluzny, M. Kubiak, M. Szymanski +3
The central area of the Sculptor dwarf galaxy was surveyed for variable stars as a side-program of the OGLE project. Light curves in the V band were obtained for 226 RR Lyr stars a…
Results from the Optical Gravitational Lensing Experiment (OGLE)
B. Paczynski, K. Z. Stanek, A. Udalski +6
The analysis of the first three years of the OGLE data revealed 12 microlensing events of the Galactic bulge stars, with the characteristic time scales in the range $ 8.6 < t_0 < 8…
Evidence for the Galactic Bar from the Two Color Photometry of the Bulge Red Clump Stars
K. Z. Stanek, M. Mateo, A. Udalski +4
The Optical Gravitational Lensing Experiment (OGLE, Udalski et al.~1994a; Paczyński et al.~1994b -- these proceedings; and references therein) is an extensive photometric search fo…
The Optical Gravitational Lensing Experiment. Deep Photometry of the Sagittarius Dwarf Spheroidal Galaxy
Mario Mateo, A. Udalski, M. Szymanski +3
We present deep CCD photometry of a field in the newly discovered dwarf spheroidal galaxy in Sagittarius (hereafter Sgr), and of a nearby control field. These data (totaling ~3.5 h…
The Optical Gravitational Lensing Experiment. the Early Warning System
A. Udalski, M. Szymanski, J. Kaluzny +4
The discoveries of 17 microlensing event candidates have been reported over the last year by three teams conducting unprecedented mass photometric searches in the direction of the…
The Optical Depth to Gravitational Microlensing in the Direction of the Galactic Bulge
A. Udalski, M. Szymanski, K. Z. Stanek +6
We present the analysis of the first two years of the OGLE search for gravitational lenses towards the Galactic bulge. We detected 9 microlensing events in an algorithmic search of…
