Abstract:
Cosmicflows-2 is a compilation of distances and peculiar velocities
for over 8000 galaxies. Numerically the largest contributions come
from the luminosity-line width correlation for spirals, the
Tully-Fisher relation (TFR), and the related fundamental plane
relation for E/S0 systems, but over 1000 distances are contributed by
methods that provide more accurate individual distances: Cepheid, tip
of the red giant branch (TRGB), surface brightness fluctuation, Type
Ia supernova, and several miscellaneous but accurate procedures. Our
collaboration is making important contributions to two of these
inputs: TRGB and TFR. A large body of new distance material is
presented. In addition, an effort is made to ensure that all the
contributions, both our own and those from the literature, are on the
same scale. Overall, the distances are found to be compatible with a
Hubble constant H0=74.4±3.0km/s/Mpc. The great interest going
forward with this data set will be with velocity field studies.
Cosmicflows-2 is characterized by a great density and high accuracy of
distance measures locally, falling to sparse and coarse sampling
extending to z=0.1.
Description:
Cosmicflows-2 is a compilation of 8315 distances (determined by six
distinct methods; Table1) within 5224 entities: 3625 of these
distances in 534 groups and 4690 singles. A precursor catalog by Tully
et al. (2008, cat. J/ApJ/676/184) has retroactively been called
Cosmicflows-1.
