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…
Study of CO2/H2O Ice Abundance Ratios in Nearby Galaxies with the Akari Near-Infrared Spectroscopy

Near-infrared Polarimetric Study of the N159/N160 Star-forming Complex in the Large Magellanic Cloud
Kwon, Jungmi; Tamura, Motohide; Jeong, Woong-Seob +4 more
We present near-infrared polarimetric results for the N159/N160 star-forming complex in the Large Magellanic Cloud with SIRPOL, the polarimeter of the Infrared Survey Facility. We separated foreground sources using their visual extinction derived from near-infrared photometric data. The 45 young stellar candidates and 2 high-excitation blobs were …
FIR View of Disks of Weak-Line T Tauri Stars
Doi, Yasuo; Takita, Satoshi; Arimatsu, Ko +2 more
We have observed ~60 Weak-line T Tauri stars (WTTSs) toward the Chamaeleon star forming region using the AKARI Far-Infrared Surveyor (FIS) All-Sky maps. We could not detect any significant emission from each source even at the most sensitive WIDE-S band. Then, we have performed stacking analysis of these WTTSs using the WIDE-S band images to impro…
