Hong et al. (2014) use 2MASS near-infrared
photometry and high signal-to-noise HI 21-cm data from the Arecibo, Green Bank,
Nancay, and Parkes telescopes to calculate the redshift-independent distances
and peculiar velocities of 2018 bright inclined spiral galaxies over the whole
sky. This project is part of the 2MASS Tully-Fisher survey (2MTF), aiming to
map the galaxy peculiar velocity field within 100 Mpc. - The image shows the
sky coverage of the 2018 2MTF galaxies in Galactic coordinates with an Aitoff
projection; red points are galaxies with positive peculiar velocities and blue
points those with negative peculiar velocities. The bulk flow direction
determined from the 2MTF sample is presented by the green circle; the size of
the circle indicates the 1 sigma error.
