Intrinsic Shapes of Very Flat Elliptical Galaxies
Intrinsic Shapes Flat Elliptical Galaxies
2011/1/11
Photometric data from the literature is combined with triaxial mass models to derive variation in the intrinsic shapes of the light distribution of elliptical galaxies NGC 720, 2768 and 3605. The infe...
A Series Solution to the Luminosity Distance in a Flat LCDM Universe
Cosmological distances Numerical methods
2010/11/15
Cosmological observations indicate that our universe is flat and dark energy (DE)
dominated at present. The luminosity distance plays an important role in the investigation
of the evolution and stru...
Rigidity of noncompact complete Bach-flat manifolds
Bach-flat manifolds zero scalar curvature
2010/3/19
Let $(M,g)$ be a noncompact complete Bach-flat manifold with positive Yamabe constant. We prove that $(M,g)$ is flat if $(M, g)$ has zero scalar curvature and sufficiently small $L_{2}$ bound of curva...
