We present a radiative transfer model for the circumstellar dust shell around a Large Magellanic Cloud (LMC) long-period variable (LPV) previously studied as part of the Optical Gravitational Lensing Experiment (OGLE) survey of the LMC. OGLE LMC LPV 28579 (SAGE J051306.40-690946.3) is a carbon-rich asymptotic giant branch (AGB) star for which we have Spitzer broadband photometry and spectra from the SAGE and SAGE-Spec programs along with broadband UBVIJHKs photometry. ...

B?rbel Koribalski (ATNF) + HIPASS and ZOA teams . The properties shown below were derived from the measurd HI properties. Displayed here are the Local Group velocities of all sources from -300 to +8000 km/s (bins are 100 km/s). Displayed here are the distances of all sources (assuming Ho = 75 km/s/Mpc). ... Displayed here are the HI masses of all sources (assuming point source distribution). Extended galaxies and pairs/groups need to be re-measured. ...

... The sky distribution of the BCGs from the HSS sample is shown in Fig. 6 together with BCGs from the SBS and Case surveys (Izotov et al. [ 1993b ]; Pustilnik et al. ... First, we compare the apparent magnitude distributions of the three samples. ... The similar behaviour of the faint end of the apparent magnitude distributions infers that the Northern BCG sample may have a similar completeness down to this limiting magnitude. ...

Aboriginal and Torres Strait Islander people developed complex knowledge systems around the sun, moon, and stars. Stellar positions and properties (such as declination, colour, brightness, and scintillation) were important for navigation, calendars, economics, and time-keeping. Transient astronomical phenomena (including comets, meteors, eclipses, and aurorae) reinforced sacred law and cultural practices and served as a moral charter. ...

... R-band images obtained at 0.8 arcsec seeing conditions have allowed us to separate foreground star from point-like extragalactic source and estimate their brightness separately. ... To study the nature and properties of the source, we observed it under high spatial resolution. ... CONCLUSION RTT150 optical observations with sub-arcsecond seeing and low resolution spectra confirm the hypothesis of superposition of a radio source onto a `normal' F/G galactic star proposed by [1]. ...

... ICND-96, Saratov, Russia. ... And though a number of efficient methods of digital sound compression is developed by far, there is still a need in new efficient methods. In this report we study a possibility of application of fractal methods to compression of speech signals. ... In this method, a speech frame is divided into larger pieces called domains, and smaller ones called regions, and an optimal set of affine transformations of domains into regions is calculated. ...

... This will be an introductory course on Artin $L$-functions (no prerequisites assumed).
