The Proper Motion of Sgr A * : II . The Mass of Sgr A
We report measurements with the VLBA of the position of Sgr A* with respect to two extragalactic radio sources over a period of eight years. The apparent proper motion of Sgr A* relative to J1745–283 is 6.379 ± 0.024 mas y −1 along a position angle of 209.60 ± 0.18 degrees, almost entirely in the plane of the Galaxy. The effects of the orbit of the Sun around the Galactic center can account for...

15 صفحه اولA kind of fuzzy upper topology on L-preordered sets
Considering a commutative unital quantale L as the truth value table and using the tool of L-generalized convergence structures of stratified L-filters, this paper introduces a kind of fuzzy upper topology, called fuzzy S-upper topology, on L-preordered sets. It is shown that every fuzzy join-preserving L-subset is open in this topology. When L is a complete Heyting algebra, for every completel...
