Observational constraints on inflation with the nonlinear sigma-fields in light of Planck 2015
Koh, Seoktae; Lee, Bum-Hoon; Tumurtushaa, Gansukh
We study an inflation model with a nonlinear sigma field which has SO(3) symmetry. The background solution of the nonlinear sigma field is linearly proportional to the space coordinates while keeping the homogeneous and isotropic background spacetime. We calculate the observable quantities, including the power spectra of the scalar and tensor mode…

On the Distance Measurements toward Young Milky Way Objects. I. Study of IC 2944
Krełowski, J.; Strobel, A.; Bondar, A. +1 more
We compare distances to a very young stellar aggregate, IC 2944, using three methods: direct parallaxes of Gaia, spectrophotometric parallax and our method based on intensities of interstellar CaII lines. The discrepancies between spectrophotometric distances and those, based on CaII K and H lines, were already reported. The interstellar CaII H an…
Initial analysis of ion fluxes in the magnetotail of Mars based on simultaneous measurements on Mars Express and Maven
Zelenyi, L. M.; Connerney, J. E. P.; Dubinin, E. M. +4 more
Simultaneous operation of two Mars satellites, equipped with instruments for the study of the plasma environment close to Mars, the European satellite Mars Express and American satellite MAVEN, allows one to investigate the influence of the interplanetary environment on the Martian magnetosphere and atmospheric losses, induced by the solar wind, f…
Energy budget during an isolated substorm using measurements of multi satellites and geomagnetic indices
Dunlop, M. W.; Ma, Yuduan; Yang, Jian +1 more
Measurements of multi satellites and geomagnetic indices are used to investigate the energy budget during an isolated substorm. The calculation of the energy transfer from the solar wind to the magnetosphere (parameter
Optical imaging and spectral study of FR-I type radio galaxy: CTD 086 (B2 1422+26B)
Pandge, M. B.; Sahu, Sheetal K.; Navale, N. R. +1 more
We present optical imaging and spectroscopic studies of the Fanaroff & Riley class I (FR I) radio galaxy CTD 086 based on Hubble Space Telescope (HST) and Sloan Digital Sky Survey (SDSS) observations. We use isophote shape analysis to show that there is no stellar disk component within CTD 086 and further that the morphological class of the ga…

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…
