We refined the fundamental parameters of the components, the orbital periods, and the conditions of photospheric heating of the secondary component by the ultraviolet radiation of the hot component. ... The observations of the star clusters associated with ultra-luminous x-ray sources (ULXs) in four galaxies on the 6-meter and VLT telescopes have shown that all the ULXs are located within 200pc of very young star clusters (younger than 5 million years). ...

Study of galaxies in a nearby Lynx-Cancer Void: project and first results Pustilnik S.A. and Tepliakova A.L. (SAO) Dwarf galaxies residing in the very low density environment (voids) are expected in the frame of modern cosmological CDM models to form later and to evolve more slowely in respect of their counterparts in a more typical environment. The available data on evolution of void population are rather scarce and indirect. ...
