J/ApJ/714/1441 Linearity of the cosmic expansion field (Sandage+, 2010)
The linearity of the cosmic expansion field from 300 to 30000 km/s and the bulk motion of the Local Supercluster with respect to the cosmic microwave background. Sandage A., Reindl B., Tammann G.A. <Astrophys. J., 714, 1441-1459 (2010)> =2010ApJ...714.1441S
ADC_Keywords: Galaxies, nearby ; Clusters, galaxy ; Radial velocities ; Supernovae ; Stars, distances Keywords: cosmic background radiation - cosmological parameters - distance scale - galaxies: distances and redshifts - stars: kinematics and dynamics Abstract: Particularly accurate relative distances are compiled and homogenized for (1) 246 Type Ia supernovae and 35 clusters with v<30000km/s, and (2) relatively nearby galaxies with 176 tip of the red-giant branch and 30 Cepheid distances. The 487 objects define a tight Hubble diagram from 300-30000km/s implying individual distance errors of ≲7.5%. Here the velocities are corrected for Virgocentric steaming (locally 220km/s) and -if v220>3500km/s- for a 495km/s motion of the Local Supercluster toward the warm cosmic microwave background (CMB) pole at l=275, b=12; local peculiar motions are averaged out by large numbers.
