Rotation curves of spiral galaxies in clusters are compared with their counterparts in the field using three criteria: (1) inner and outer velocity gradients, (2) M/L gradients, and (3) Burstein's mass type methodology. Both H伪 emission-line rotation curves and more extended Hi rotation ...
9. FIGURE CAPTIONS 1) Rotation curves of spiral galaxies under the generalized Einstein action. The numbers on the curves indicate the values of a in Eq. (2.23). The prediction of Newtonian theory for a = 2 is also given by a broken curve for comparison. 2) Scale factor of universe as...
However, the implied central face-on opacity of tau = 2-4 for the most luminous galaxies is embarrassingly high compared with studies of edge-on galaxies, which yield central face-on opacities equal to at most t = 1 in the optical band. I show that the controversy can be resolved by ...
We have investigated the stellar light distribution and the rotation curves of high-luminosity spiral galaxies in the local Universe. The sample contains 30 high-quality extended H alpha and HI rotation curves. The stellar disk scale-length of these obje
摘要: We decompose the rotation curves of 34 local bright spiral galaxies into baryonic and dark matter components. Analysis of the resulting dark-to-luminous matter distributions shows that they are self-s关键词: CiteSeerX citations Rotation Curves of Spiral Galaxies Yoshiaki Sofue Vera Rubin ...

Low surface brightness galaxy rotation curves in the low energy limit of Rn gravity: no need for dark matter? We investigate the possibility that the observed flatness of the rotation curves of spiral galaxies is not evidence for the existence of dark matter haloes... S Capozziello,VF Cardone...
We have compiled high-resolution position-velocity diagrams observed along the major axes of nearby spiral galaxies in the CO line emission, and derived rotation curves for the inner regions of the galaxies. We have combined the inner rotation curves with the outer H I and optical rotation curves...
