... Our recent observations with the Hubble Space Telescope (August 29, 2014) led to revealing a highly isolated dwarf spheroidal galaxy KKs 3 situated at a distance of 2.12 0.07 Mpc from the Milky Way. The dSph galaxy locates on the southern sky (RA=02 h 24 m 44.4 s , Dec.= ... Over the last decade, about 30 dSph galaxies have been discovered inside the Local Group through systematic search in the vicinity of M31 and more that a dozen dSphs were discovered in the nearby group around M81. ...

Next: The sample description Up: Spectral survey of Case Previous: Spectral survey of Case . Several large objective-prism surveys have been done during last two decades. ... Other surveys, such as Tololo (Smith et al. ... 1993 ], [ 1994 ]; Thuan et al. ... Thus we carried out the follow-up spectroscopy for those Case candidates, which left behind the scope of the previous slit-spectroscopy studies, in order to combine all available data and produce the BCG sample in the zone of Case survey. ...

New polar ring galaxies catalogue. ... A host galaxy like S0 or E, the polar component is like spirals or irregular galaxies ( gas -rich and bluer) Not only narrow annuli, but also extended disc-like rings Warped and inclined rings Only 20 large-scale polar rings + 6 inner rings were kinematically confirmed from the Whitmore et al. list: - HI maps (Cox et al; Sparke et al. ) - optical-long slit spectroscopy (Reshetnikov et al) - optical ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
