An investigation of the spectral energy distribution (SED) of the compact steep-spectrum (CSS) source and possible radio-loud narrow-line Seyfert 1 galaxy (NLS1), PKS 2004-447, is presented. ... Analysis of a non-contemporaneous, low-resolution optical spectrum suggests that the narrow-line region (NLR) is much more reddened than the X-ray emitting region suggesting that the gas-to-dust ratio in PKS 2004-447 may be very different than in our own Galaxy. ...

... We are exploring the evolution of massive binary star populations for a nuclear starburst occuring in the conditions similar to the Milky Way galaxy, in its central part, on a time scale of 10 Myr. ... Our results include the number of X-ray transients (NS + main sequence star), super-accreting black holes (BHs), and binaries consisting of a BH + supergiant, all as functions of time. ...

... Einstein data for SNR are available as images on magnetic tape or diskette and as tables of counting rates. ... In seven cases, with coverage from 35% to 90%, we have calculated an HRI rate for the entire SNR by using the observed IPC data and assuming the ratio of HRI to IPC rates was the same for the observed and the unobserved parts of the remnant. ... Positions of the bright bulge sources and remnants in the galactic plane are known and the rates in table 2 are free of the effects of these. ...
