Wavefront retrieval through random pupil plane phase probes: Gerchberg-Saxton approach

Eugene Pluzhnik, Dan Sirbu, Ruslan Belikov +2

A pupil plane wavefront reconstruction procedure is proposed based on analysis of a sequence of focal plane images corresponding to a sequence of random pupil plane phase probes. T…

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…
