I was born on April 12, 1958, in Moscow, USSR, and I have a Russian nationality. I graduated the Lomonosov Moscow State University in 1981, obtained there my Ph.D.degree in 1984 (the topic of the dissertation: "Stellar populations and evolution of galaxies") and a degree of Doctor of Physical-Mathematical Sciences in 1994 (the dissertation "Stellar population of galactic nuclei"). Since 1984 I hold a permanent position at the Sternberg Astronomical Institute (Moscow). ...

Dynamical chaos in the problem of magnetic jet collimation O. Yu. ... In the paper of Bisnovatyi-Kogan (2007) magnetic collimation resulting from torsional oscillations of a cylinder with elongated magnetic field and periodically distributed initial rotation around the cylinder axis was considered. ... Space and time periods of oscillations depend on the conditions of jet formation: the length-scale, the amplitude of the rotational velocity, and the strength of the magnetic field. ...

... Сегодня: 10 апреля 2016 г. После Большого взрыва Вселенная в течение чрезвычайно короткого промежутка времени находилась в состоянии хаоса - к такому выводу пришла группа физиков, разработавшая модель, которая описывает самые ранние этапы эволюции Вселенной. ... Предположения, что после Большого взрыва Вселенная на короткое время перешла в состояние хаоса, высказывались и раньше, однако авторы новой работы, по их словам, представили новые исчерпывающие доказательства правомерности такой версии. ...

It is shown that in this very general framework the well established anti-correlation between variability amplitude and wavelength can only be understood as an effect of an underlying spectral component which remains stable on long time-scales, and is redder than the variable component. ...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...
