| 英文摘要 | We present an analysis of the fluctuation of the local hubble flow using 350 galaxies in the local volume (d < 5 mpc, hereafter lv) with accurate measurements of distances, positions and radial velocities, and compare the results with the theoretical prediction of the local hubble flow induced by density perturbations. this allows us to set a useful constraint on the local omega parameters: omega(m) similar to 0.6 and omega(lambda) similar to 0.7, which may serve as compelling evidence for the existence of dark energy in the local universe. |
