The Search for Black Holes of Intermediate Masses with Ground-based and Space-borne Observatories and the Virtual Observatory Data
Resumo
Black holes, mysterious objects, have attracted scientists for several decades. Today we confidently observe two types of black holes, the black holes of stellar masses that occur as the result of the collapse of massive stars and supermassive blackholes in the central parts of galaxies. However in the late eighties of the XXth century astronomers found observational evidences for one more type of black holes, the black holes of intermediate masses. In this article we discuss how modern ground-based and space-borne telescopes and the Virtual observatory help astronomers to search and discover the black holes of this particular type.

The Sun in Terahertz Waves
Resumo
Hundred years ago astronomers had access to only the optical wavelength band. However in the XX century developing science and technology opened for scientists many new wavelength bands (radio, X-rays, gamma rays etc.), which allowed us to look much farther and deeper. In this article we discuss how our knowledge about the lower layers of the solar atmosphere progressed due to the sub-terahertz and terahertz observations.
