13. Pulsar Highlights - A Dozen new MSPs in Globular Clusters
A Canadian and American team of Astronomers have used the 305-m wide Arecibo radio dish, the world's largest and most sensitive radio telescope, to uncover a dozen new super-fast-spinning pulsars. The team directed their search for these rare and exotic stars by pointing the Arecibo radio telescope towards massive star clusters, called Globular Clusters, orbiting our Milky Way galaxy. ... One of the most exotic residents in the Globular cluster system are the millisecond pulsars. ...

18. The spectral energy distribution of PKS 2004-447: a compact steep-spectrum
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. ...

In spite of the lack of rich clusters around us and the presence of large volumes completely free from galaxies (voids), the mean luminosity densities and the mean density of hydrogen mass in the Local Universe is one and a half - twice as high as their mean global values. However, the mean local density of the baryon mass is only 2% of the critical density of the Universe, which is twice as less as the baryon density from the nucleosynthesis data (local paradox of the baryon mass). ...
