Scientific problems addressed by the Spektr-UV space project (world space Observatory—Ultraviolet)
Werner, K.; Strassmeier, K. G.; Lammer, H. +29 more
The article presents a review of scientific problems and methods of ultraviolet astronomy, focusing on perspective scientific problems (directions) whose solution requires UV space observatories. These include reionization and the history of star formation in the Universe, searches for dark baryonic matter, physical and chemical processes in the i…
Detail studies of the physical properties in the outer regions of galaxy clusters using Suzaku observations
Babyk, Iu. V.
A detailed physical analysis of five nearby galaxy clusters using Suzaku observationsis presented. The low and stable level of the instrumental background at large radii facilitate the determination of the main physical characteristics in clusters at the virial radius. The temperatures, metal abundances, and entropy profiles have been constructed …
Large-scale fluctuations in the number density of galaxies in independent surveys of deep fields
Baryshev, Yu. V.; Shirokov, S. I.; Lovyagin, N. Yu. +1 more
New arguments supporting the reality of large-scale fluctuations in the density of the visible matter in deep galaxy surveys are presented. A statistical analysis of the radial distributions of galaxies in the COSMOS and HDF-N deep fields is presented. Independent spectral and photometric surveys exist for each field, carried out in different wave…
Characteristics of GPS sources in the Planck survey
Volvach, A. E.; Kardashev, N. S.; Larionov, M. G. +1 more
Two series of 22.2 and 36.8-GHz observations of 43 GHz-Peaked Spectrum (GPS) radio sources from the Planck survey have been carried out using the 22-m radio telescope of the Crimean Astrophysical Observatory in 2014-2015, with the aim of studying the variability of these sources. The interval between the two series of observations was about nine m…
Long-term variability of active galactic nuclei from the "Planck" catalog
Volvach, A. E.; Kardashev, N. S.; Larionov, M. G. +1 more
A complete sample of 104 bright active galactic nuclei (AGNs) from the "Planck" catalog (early results) were observed at 36.8 GHz with the 22-m radio telescope of the Crimean Astrophysical Observatory (CrAO).Variability indices of the sources at this frequency were determined based on data from theWMAP space observatory, theMetsa¨ hovi RadioObserv…
IR photometry and models for the dust envelopes of two carbon stars
Bogdanov, M. B.; Taranova, O. G.
The results of JHKLM photometry of two carbon stars are presented: the irregular variable NQ Cas and the Mira star BD Vul. Data on the mean fluxes supplemented with mid-IR observations with the IRAS, AKARI, andWISE satellites are used to compute spherically symmetrical model dust envelopes for the stars, consisting of particles of amorphous carbon…
