Next: The Stellar Population in Up: NICMOS Science Previous: NICMOS Coronagraphic Surveys-Preliminary Results . ... Searching around young stars . ... We are using NICMOS to search for very low-mass stellar and sub-stellar companions around nearby, young, main-sequence stars. ... NICMOS, coronagraph, young stars, brown dwarfs . ... We present images of a possible companion, probably a low-mass M star, to the star HD102982 which demonstrates our ability to detect substellar objects. ...

The direct detection of gravitational waves is one of those events long-expected by physicists that are nevertheless a significant occurrence which excites the world scientific community as if something unexpected has happened. ... Many rumors leaked ahead of the conference, and the fact that something (that is, a signal corresponding to gravitational waves) was discovered by LIGO (Laser Interferometer Gravitational-Wave Observatory) was discussed on the sidelines. ... arXiv:1602.03868 . ...

... ASTEROID’S MOONS : DISCOVERY BY RADAR . ... Moons of known asteroids have a low position ambiguity, which makes their discovery with powerful ground-based radar much easier than the discovery of new asteroids or other objects of Solar System. ... The other technique is a direct detection of radar echo from an asteroid moon. ... However, the diameter of a ground-based fully-steerable reflector is limited by 120-150 m to make it possible to perform two different functions: focusing and tracking (fig. ...

It could be that SETI signals have arrived at the Earth, but are lower then the noise level, and our receivers cannot detect them. ... Fig. ... It follows that two zones form around the star with civilization X: "Zone Yes", where its SETI signal can be detected, and "Zone No", where its signals are hidden by noise (Fig. ... In practice, it is more efficient to use a time factor, since the problem of SETI contact does not limit the duration of the signal element and semantic text. ...

... Scientists from G. I. Budker Institute of Nuclear Physics- Syberian Branch of the Russian Academy of Science, Novosibirsk State University, Novosibirsk State Technical University, Samara State Aerospace University (SSAU) and Image Processing Systems Institute (IPSI) of the Russian Academy of Science, became the first people in the world obtained terahertz non-diffractive twisted Bessel beams and used them for the first time the formation of surface electromagnetic waves on the metal surface. ...

Nowadays at the Department the experimental and theoretical investigations, including astronomical and ionospheric observations, active experiments with space vehicles are taking place. ... Solar Corona physics and erruptive phenomenae. ... Stellar astronomy. ... The Department has organized and put into practice more then 50 expeditions for observation of Solar ecllipces, aurorae polaris, comets, meteor streams, controlled space experiments, and also for investigations of geophysical characteristics. ...
