The Optical Gravitational Lensing Experiment. a Hunt for Caustic Crossings in Qso 2237+0305. *
In 1998 The Optical Gravitational Lensing Experiment (OGLE) successfully implemented automated data reductions for QSO 2237+0305. Using a new image subtraction method we achieved a differential photometry scatter of 1–5% for images A–D respectively. Combined with a time sampling of 1–2 times a week this is sufficient for early detection of caustic crossings. Nearly real time photometry of QSO 2...
متن کاملThe Optical Gravitational Lensing Experiment Monitoring of Qso 2237+0305 *
We present results from 2 years of monitoring of Huchra's lens (QSO 2237+0305) with the 1.3 m Warsaw telescope on Las Campanas, Chile. Photometry in the V band was done using a newly developed method for image subtraction. Reliable subtraction without Fourier division removes all complexities associated with the presence of a bright lensing galaxy. With positions of lensed images adopted from H...
متن کاملQSO-Galaxy Association and Gravitational Lensing
The amplification caused by gravitational light bending by compact objects in a foreground galaxy can affect the apparent number density of background QSOs, as well as their distribution in the fields of galactic halos. In this work we investigate the number enhancement of QSOs in the fields of galactic halos caused by point mass lensing effect and singular isothermal lensing effect, and apply ...
متن کاملQSO mass constraints from gravitational lensing studies of quasar pairs
New constraints on the mass of quasars are derived from gravitational lensing studies of the QSO pairs Q1548+114 A & B and Q1148+0055 A & B, for which new ground-based and Hubble Space Telescope (HST) direct imagery have been obtained. In the case of Q1548+114 A & B, QSO A has been resolved into its host galaxy and a close companion. The nondetection with HST of a secondary lensed image of the ...
متن کاملThe Optical Gravitational Lensing Experiment. Cepheids in Star Clusters from the Magellanic Clouds
We present Cepheids located in the close neighborhood of star clusters from the Mag-ellanic Clouds. 204 and 132 such stars were found in the LMC and SMC, respectively. The lists of objects were constructed based on catalogs of Cepheids and star clusters, recently published by the OGLE-II collaboration. Location of selected Cepheids on the sky indicates that many of them are very likely cluster ...
