... 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. ...

... Studies of the pathlength fluctuations through the troposphere using geostationary satellite. ... Relationships that connect the temporal structure function of fluctuations measured with the temporal spatial structure functions of pathlength through the troposphere were obtained. ... On the base of experimental data there were determined the parameters of temporal structure function of pathlength through the troposphere (exponent, structure coefficient). ...

... As a result of BTA observations of 23 chemically peculiar stars with strong magnetic fields, it was found that in 22 of them the longitudinal magnetic field, measured from the hydrogen line cores are considerably lower (by about 1/3) than the value measured from metal lines in the same spectra. ... New approaches need to be developed in order to interpret the data. ... The Zeeman spectrum of a star with a strong magnetic field, 53 Cam. ...

The following topics are included: acquaintance with a LabView software most often applied in laboratories to automation of experiment, a photolithography without which the modern manufacturing techniques of low-dimensional structures is impossible, as well as the tasks allowing students to master bases of low-temperature experiment, a technique of a high pressure, work with low-dimensional semiconductor structures. ...

To understand the impact of low metallicities on giant molecular cloud (GMC) structure, we compare far-infrared dust emission, CO emission, and dynamics in the star-forming complex N83 in the Wing of the Small Magellanic Cloud (SMC). ... This allows us to resolve the relative structures of H2, dust, and CO within a GMC complex, one of the first times such a measurement has been made in a low-metallicity galaxy. ...
