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…
Q2237+0305 source structure and dimensions from light curves simulation
V. G. Vakulik, R. E. Schild, G. V. Smirnov +2
Assuming a two-component quasar structure model consisting of a central compact source and an extended outer feature, we produce microlensing simulations for a population of star-l…
Observational determination of the time delays in gravitational lens system Q2237+030
V. Vakulik, R. Schild, V. Dudinov +4
We present new brightness monitoring observations of the 4 components of gravitationally lensed system Q2237+0305, which show detection of an intrinsic quasar brightness fluctuatio…
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…
Microlensing of a Ring Model for Quasar Structure
Rudolph Schild, Viktor Vakulik
Microlensing observations of the Q0957+561 A,B have consistently shown evidence for structure in the quasar that has not been evident in available microlensing models, where the lu…
