What Do We Mean by Malmquist Bias?
Martin A. Hendry, John F. L. Simmons, Andrew M. Newsam
In this paper we review the two main approaches to the problem of Malmquist bias which have been adopted in the cosmology literature, and show how these two formulations of the pro…
Bias in Velocity Field Recoveries
Andrew Newsam, John F. L. Simmons, Martin Hendry
We investigate the effect of using different distance estimators on the recovery of the peculiar velocity field of galaxies using Potent. An inappropriate choice of distance estima…
Potent and Max-Flow Algorithms
John F. L. Simmons, Andrew Newsam, Martin Hendry
Although Potent purports to use only radial velocities in retrieving the potential velocity field of galaxies, the derivation of transverse components is implicit in the smoothing…
