PARAMETERS OF THE TRANSIENT SIGNALS DETECTED IN THE DECAMETER SURVEY OF THE NORTHERN SKY
Journal Title: Odessa Astronomical Publications - Year 2016, Vol 29, Issue
Abstract
Decameter all-sky Survey has been running at UTR-2 radio telescope over the past few years, about 70% of observational data are processed. The Survey is aimed at searching for pulsars and transient sources. Present work shows results of processing aforementioned part of data in order to find transient sources. The processing allowed detecting more than 500 signals. Distributions of the signals’ parameters (dispersion measures, galactic latitudes, “signal-to-noise-ratios” etc.) are obtained, which give reason to consider the vast majority of these pulses the signals from cosmic sources.

THE RELATIVE WAVELENGTH INDEPENDENCE OF IR LAGS IN ACTIVE GALACTIC NUCLEI: IMPLICATIONS FOR THE DISTRIBUTION OF THE HOT DUST
We show that, contrary to simple predictions, most AGNs show at best only a small increase of lags in the J, H, K, and L bands with increasing wavelength. We suggest that a possible cause of this near simultaneity of the...
STABILITY OF STELLAR SYSTEMS ORBITING SGR A*
Path equations of different orbiting objects in the presence of very strong gravitational fields are essential to examine the impact of its gravitational effect on the stability of each system. Implementing an analogous...
SEASONAL VARIATIONS OF THE IONOSPHERE SCINTILLATIONS PARAMETERS OBTAINED FROM THE LONG OBSERVATIONS OF THE POWER COSMIC RADIO SOURCES AT THE DECAMETER WAVE RANGE
Observations of the four power cosmic radio sources were carried out on the radio telescope (RT) URAN-4 during 1987-1990 and 1998-2007 at the frequencies 20 and 25 MHz. Effects of ionosphere and in particular existence o...
ON THE CONCEPT OF THE ENHANCED FON CATALOG COMPILATION
We suppose to compile the enhanced version of FON (Photographic Survey of the Northern Sky) catalog of stellar positions and B-magnitudes in the sky region from -20 to 90 degrees on declination. The photographic base of...
