The Vanishing & Appearing Sources during a Century of Observations project: I. USNO objects missing in modern sky surveys and follow-up observations of a "missing star"
Beatriz Villarroel, Johan Soodla, Sébastien Comerón +19
In this paper we report the current status of a new research program. The primary goal of the "Vanishing & Appearing Sources during a Century of Observations" (VASCO) project is to…
A method of immediate detection of objects with a near-zero apparent motion in series of CCD-frames
V. E. Savanevych, S. V. Khlamov, I. B. Vavilova +9
The paper deals with a computational method for detection of the solar system minor bodies (SSOs), whose inter-frame shifts in series of CCD-frames during the observation are comme…
The evolution of the luminosity-temperature-mass relations of hot gas in Chandra clusters at 0.4 < z < 1.4
Iu. Babyk, I. Vavilova
We analyzed the luminosity-temperature-mass of gas (L_{X} - T - M_{g}) relation for sample of galaxy clusters that have been observed by the Chandra satellite. We used 21 high-reds…
The Dark Matter Haloes of Chandra X-ray Galaxy Clusters and Baryons Effect
Iu. Babyk, I. Vavilova, A. Del Popolo
We present results based on Chandra observations of a large sample of 129 hot galaxy clusters. We measure the concentration parameter c_200, the dark mass M_200 and the baryonic ma…
High-order 3D Voronoi tessellation for identifying Isolated galaxies, Pairs and Triplets
A. Elyiv, O. Melnyk, I. Vavilova
Geometric method based on the high-order 3D Voronoi tessellation is proposed for identifying the single galaxies, pairs and triplets. This approach allows to select small galaxy gr…
Non-metric Generalizations of Relativistic Gravitational Theory and Observational Data Interpretation
A. N. Alexandrov, I. B. Vavilova, V. I. Zhdanov
We discuss theoretical formalisms concerning with experimental verification of General Relativity (GR). Non-metric generalizations of GR are considered and a system of postulates i…
