Genus Topology of the Cosmic Microwave Background from the WMAP 3-Year Data

J. Richard Gott, Wesley N. Colley, Chan-Gyung Park +2

We have independently measured the genus topology of the temperature fluctuations in the cosmic microwave background seen in the Wilkinson Microwave Anisotropy Probe (WMAP) 3-year…

Map Projections Minimizing Distance Errors

J. Richard Gott, Charles Mugnolo, Wesley N. Colley

It is useful to have mathematical criteria for evaluating errors in map projections. The Chebyshev criterion for minimizing rms (root mean square) local scale factor errors for con…

A Rapid Microlensing Event in the Q0957+561 A,B Gravitational Lens System

Wesley N. Colley, Rudolph E. Schild

We re-analyze brightness data sampled intensively over 5 nights at two epochs separated by the quasar lens time delay, to examine the nature of the observed microlensing. We find s…
