Astronomical Image Processing for High-Accurate Astrometry Data
Akhmetov, V. S.; Dmytrenko, A. M.
This article presents the main results of the initial processing of some of the astronomical images obtained from the archive of the digitized photographics survey of the whole sky SuperCOSMOS. Using of the median filtering and gausian convolution procedure with the adaptive kernel allows to carry out the initial processing of astronomical images …
Supervised Automatic Identification of Extragalactic Sources in the WISExSUPERCOSMOS Catalogue
Khramtsov, V.; Akhmetov, V.
We present new catalogue of ∼8,500,000 extragalactic objects as a result of automatic classification of WISE and SuperCOSMOS (SCOS) cross-identification product. The main goal is to create a set of candidates in extragalactic objects due to colour (photometric) features through machine learning techniques. Extragalactic sources were separated from…
X-ray Emission and Orientation of Selected PF Galaxy Clusters
Tugay, A. V.; Dylda, S. S.; Panko, E. A.
X-ray counterparts for 35 galaxy clusters contained in the PF catalogue of galaxy clusters and groups were found in XMM-Newton archive. 22 ones (all from ACO catalogue) have extended elliptic X-ray haloes appropriate for determination of orientation. Position angles and eccentricities were calculated and compared with cluster orientations optical …
Modern CCD Observations of Selected Minor Planets for the Connection of Dynamic and Kinematic Coordinate Systems
Maigurova, N.; Pomazan, A.
One of the methods of determining the orientation parameters of the dynamic and kinematic coordinate systems is to use of long-term series of ground-based observations of selected asteroids. For achievement of the best accuracy of the link parameters the high precision and uniformly covering the asteroids orbit observations are necessary. The anal…

Catalog of Positions and B Magnitudes of Stars in the Circumpolar Region of Northen Sky Survey (fon) Project
Andruk, V. M.; Pakuliak, L. K.; Golovnia, V. V. +4 more
The catalog of star positions and B-magnitudes for the circumpolar region (from 58° to 90° in declination) of Northern Sky Survey project has been created under the motto of the rational use of resources accumulated in UkrVO JDA (Joint Digital Archive) in MAO NASU. The total amount of processed plates is 477. Digitizing of astronegatives has been …
Catalog of Astronomical Positions of Saturn's Moons Obtained by Photographic Observations at the Mao Nasu in 1961-1991
Andruk, V. M.; Pakuliak, L. K.; Yizhakevych, O. M.
In the framework of UkrVO national project the new methods of plate digital image processing are developed. The photographic material of the UkrVO Joint Digital Archive (JDA, http://194.44.35.19/vo-mao/DB/ archivespecial.php) is used for the solution of classic astrometric problem - positional and photometric determinations of objects registered o…
X-Ray Spectral Properties of the Isolated AGNs: NGC 1050, NGC 2989, ESO 317-038, ESO 438-009
Vasylenko, A. A.; Babyk, Iu. V.; Vavilova, I. B. +1 more
We have analyzed the spectral data obtained by XMM-Newton, Swift, Chandra, and INTEGRAL space observatories for several isolated AGNs from 2MIG catalogue, for which the available X-ray data were accessed. Among these objects were CGCG 179-005, NGC 6300, NGC 1050, NGC 2989, WKK 3050, ESO 438-009, and ESO 317-038. We determined corresponding spectra…
Catalogues of the Faint Objects in the Areas with Gamma-Ray Bursts
Andruk, V. M.; Pakuliak, L. K.; Golovnia, V. V. +5 more
The results of GRB observations are being published in the GCN Circulars in real-time. To study all the objects in the sky areas around the GRBs we identified them on the digitized MAO Double Wide angle Astrograph (DWA) plates (D/F=40/200) within a circle with the radius of dozens of arcminutes. We selected only GRBs with the positional accuracy b…
The Kinematics Parameters of the Galaxy Using Data of Modern Astrometric Catalogues
Akhmetov, V. S.; Fedorov, P. N.; Velichko, A. B. +1 more
Based on the Ogorodnikov-Milne model, we analyze the proper motions of XPM2, UCAC4 and PPMXL stars. To estimate distances to the stars we used the method of statistical parallaxes herewith the random errors of the distance estimations do not exceed 10%. The method of statistical parallaxes was used to estimate the distances to stars with random er…
