PG 1115+080: variations of the A2/A1 flux ratio and new values of the time delays
V. S. Tsvetkova, V. G. Vakulik, V. M. Shulga +15
We report the results of our multicolor observations of PG 1115+080 with the 1.5-m telescope of the Maidanak Observatory (Uzbekistan, Central Asia) in 2001-2006. Monitoring data in…
Time delays in PG1115+080: new estimates
V. G. Vakulik, V. M. Shulga, R. E. Schild +13
We report new estimates of the time delays in the quadruple gravitationally lensed quasar PG1115+080, obtained from the monitoring data in filter R with the 1.5-m telescope at the…
Microlensing Effects in Atmospheres of Substars
L. A. Berdina, A. A. Minakov
The purpose of the present work is the study of focusing properties of atmospheres of substars that is necessary for adequate interpreting of observational data and for solving the…
Spatial and Temporal Variations of Light Curves in Gravitationally Lensed Sources
A. A. Minakov, V. G. Vakulik
Effects of macro-and microlensing on the spatial and temporal characteristics of images of remote sources, observed through the inner regions of lensing galaxies are discussed. A p…
Color Effects Associated with the 1999 Microlensing Brightness Peaks in Gravitationally Lensed Quasar Q2237+0305
V. G. Vakulik, R. E. Schild, V. N. Dudinov +9
Photometry of the Q2237+0305gravitational lens in VRI spectral bands with the 1.5-m telescope of the high-altitude Maidanak observatory in 1995-2000 is presented. Monitoring of Q22…
