Old Galactic open clusters
(Preview)
Title: The old Galactic open clusters FSR1716 and Czernik23 Authors: Charles Bonatto, Eduardo Bica Open clusters older than ~ 4 Gyr are rare in the Galaxy. Affected by a series of mass-decreasing processes, the stellar content of most open clusters dissolves into the field in a time-scale shorter...

First Massive Galaxies
(Preview)
First results from the GOODS NICMOS survey, the largest Hubble Space Telescope programme ever led from outside of the United States, reveal how the most massive galaxies in the early Universe assembled to form the most massive objects in the Universe today. Dr Chris Conselice from the University o...

Quasar 3C334
(Preview)
Title: Are 3C249.1 and 3C334 restarted quasars? Authors: Andrzej Marecki This Research Note follows up a Letter in which I posit that J1211+743 is a restarted radio source. This means that its structure, where the jet points to the relic lobe, is only apparently paradoxical. Here, I propose the sam...

Title: Metal-poor Galaxies in the Local Universe Authors: Eva K. Grebel (ARI/ZAH, Heidelberg University) A galaxy's mean metallicity is usually closely correlated with its luminosity and mass. Consequently the most metal-poor galaxies in the local universe are dwarf galaxies. Blue compact d...
