Most current theories for magnetospheric emission can be grouped into polar cap, outer gap, and nebular models. These models, at least in some cases, need not be mutually exclusive; the Crab pulsar (among others), for example, shows clear evidence for pulsed emission from the magnetosphere and unpulsed emission from the surrounding nebula. ... This suggestion is strengthened by observation of a distinct soft emission component, consistent with the cooling scenario, from several of these pulsars. ...

SWIRL DISTRIBUTION ON THE LUNAR SURFACE: LOCATIONS ANTIPODAL TO THE YOUNG BASINS? ... There are two main classes of hypothesises of the swirl origin: formation of the swirls in the regions antipodal to large impact basins (1), and formation of the swirls in result of cometary impacts (2). ... The Orientale basin is youngest. ... Fig. ... On the other hand, there are two cases of absence of correlation between swirl areas and regions antipodal to impact basins (for small swirl formations). ...

Arecibo Galaxy Environment Survey (AGES) The M74 group is a gas-rich galaxy group located at roughly 10 Mpc and is similar in makeup to the Local Group. M74 dominates the surrounding region and is accompanied by several dwarf galaxies, some of which are star-forming. ... We have decided upon a drift mapping approach to scan the entire region. We have defined 5 constant declination scans 5 in length, separated by approximately one full ALFA footprint. ... START TIME (AST) . END TIME (AST) . ...

... As is known, the observed distribution of massive stars in the direction of the Galactic center looks very peculiar: the vast majority of all massive stars are concentrated towards the central 1 pc or so (Genzel et al. ... In order to compare the observed distribution of X-ray sources in the Galactic center with what would be expected from the population synthesis computations, we have considered two hypothetical scenarios for the location of the starburst. ...
