Chains of Group Localizations [PDF]
We construct long sequences of localization functors L_a in the category of abelian groups such that L_a > L_b for infinite cardinals a < b less than some k. For sufficiently large free abelian groups F and a < b we have proper inclusions of L_aF into L_bF.

Galaxy pairs in the Local Group [PDF]
Abstract Current models of galaxy formation predict that galaxy pairs of comparable magnitudes should become increasingly rare with decreasing luminosity. This seems at odds with the relatively high frequency of pairings among dwarf galaxies in the Local Group. We use literature data to show that ∼30 per cent of all the satellites of the

Automorphisms of locally compact groups [PDF]
It is proved that for arbitrary locally compact groups G the automorphism group Aut (G) is a complete topological group. Several conditions equivalent to closedness of the group Int (G) of inner automorphisms are given, such as G admits no nontrivial central sequences. It is shown that Aut (G) is topologically embedded in the automorphism group Aut^(G)

Star Formation Histories with Gaia: The Galaxy and Beyond
ESA’s Gaia mission will provide accurate astrometric, photometric and spectroscopic data for millions of stars in the Galaxy and beyond. We discuss the prospects of using this vast amount of astrophysical information for understanding star formation ...

Several decades of observations of the most massive and most luminous stars have revealed a complex upper HR Diagram, shaped by mass loss, and inhabited by a variety of evolved stars exhibiting the consequences of their mass loss histories.

Neolithic Culture: the issues of interpretation
In Soviet science, the prevailing viewpoint was that the Neolithic culture corresponded to a group of related tribes. A.A. Formozov and M.V. Voyevodsky also distinguished larger communities: cultural areas, zones, provinces.
