Reionization time of the Local Group and Local-Group-like halo pairs [PDF]
, 2022 International audiencePatchy cosmic reionization resulted in the ionizing UV background asynchronous rise across the Universe. The latter might have left imprints visible in present day observations.

Morphological transformation of dwarf galaxies in the Local Group [PDF]
, 2015 In the Local Group there are three main types of dwarf galaxies: Dwarf Irregulars, Dwarf Spheroidals, and Dwarf Ellipticals. Intermediate/transitional types are present as well.

Chains of Group Localizations [PDF]
Communications in Algebra, 2011 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]
Monthly Notices of the Royal Astronomical Society: Letters, 2013 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

Galaxies, 2019 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.

Automorphisms of locally compact groups [PDF]
Pacific Journal of Mathematics, 1978 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
Open Astronomy, 2003 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 ...

TYPOLOGY OF SOME LOCAL GROUPS OF CERAMICS OF THE EARLY BRONZE PERIOD OF ARMENIA [PDF]
Banber Arevelagitut'yan Instituti, 2019 The changes in morphology of vessels of Shengavit culture chronology became evident period of time. New forms emerge in the advanced and late stages. New forms are becoming more diverse, it can be conditioned with lifestyle.
