The dark matter fraction in the total mass of the Q2237+0305 galaxy was estimated to be less than 50% at the distance of 0.8Kpc from its nucleus. The upper limit for the a possible presence of the dark matter substructures was estimated for the PG 1115+080 lensing galaxy. The new more reliable estimates of the time delays in PG1115+080 and H1413+117 was obtained. Product Description popup.authors Александров А.О. Бєрдіна Л.А. Баннікова О.Ю. Вакулік В.Г. Дудінов В.М.
