Focusing of Quasar Radiation in the Gravitational Field of a Microlens-Star Inside a Macrolens- Galaxy. 2. Intensity Contours Structure of the Radiation Source Visible Image
In the approximation of Sobolev and paraxial optics methods, the focusing effect of a complex gravitational lens formed by the gravitational fields of a macrolens-galaxy and a microlens-star was analyzed. The problem is solved for an arbitrary location of the microlens along the source – macrolens –...

In the approximation of Sobolev and paraxial optics methods, the focusing effect of a complex gravitational lens formed by the gravitational fields of a macrolens-galaxy and a microlens-star was analyzed. The problem is solved for an arbitrary location of the microlens along the source – macrolens – observer route. Intensity contours of images were constructed and magnification factor of a complex lens was calculated. It was shown that the microlens renders the greatest influence on the focusing effect when it is located on the macrolens – observer route. The obtained results can be used in solving the inverse problem of parameters recovery of dark matter by observing the microlensing effect. В приближениях методов Соболева и параксиальной оптики проведен анализ эффекта фокусировки сложной гравитационной линзы, образованной полями тяготения макролинзы-галактики и микролинзы-звезды. Найдены решения задачи при произвольном расположении микролинзы вдоль трассы источник – макролинза – наблюдатель. Построены изофоты изображений и рассчитан коэффициент усиления сложной линзы. Показано, что наибольшее влияние на эффект фокусировки микролинза оказывает в том случае, когда она расположена на участке трассы макролинза – наблюдатель. Полученные результаты могут быть использованы при решении обратной задачи восстановления параметров скрытой массы по наблюдениям эффекта микролинзирования.

It was shown that the microlens renders the greatest influence on the focusing effect when it is located on the macrolens – observer route.
