... We show how wavelength-dependent time delays between continuum flux variations of active galactic nuclei (AGNs) can be used to test the standard black hole--accretion disc paradigm, by measuring the temperature structure T(R) of the gaseous material surrounding the purported black hole. ... We assume that the observed time delays are indeed caused by a classical accretion disc structure, and derive a redshift-independent luminosity distance to NGC 7469. ...

... 2005: . ... Orbital period of an X-ray transient source in the system CI Cam. For the first time, the orbital motion of a compact component of the X-ray transient CI Cam has been found, the orbital period (19.41 days) and eccentricity (0.62) have been determined, masses of stars of the system have been estimated. The compact component of the system is most likely to be a white dwarf. Archive . ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...
