Optimal Moments for Velocity Fields Analysis
Hume A Feldman, Richard Watkins, Adrian Melott +1
We describe a new method of overcoming problems inherent in peculiar velocity surveys by using data compression as a filter with which to separate large-scale, linear flows from sm…
Numerical study of the cosmological velocity field as a function of density
Alvaro Dominguez, Adrian L. Melott
We report on a new study of the velocity distribution in N-body simulations. We investigate the center-of-mass and internal kinetic energies of coarsening cells as a function of ti…
Did a gamma-ray burst initiate the late Ordovician mass extinction?
A. Melott, B. Lieberman, C. Laird +6
Gamma-ray bursts (hereafter GRB) produce a flux of radiation detectable across the observable Universe, and at least some of them are associated with galaxies. A GRB within our own…
Simulated Versus Observed Cluster Eccentricity Evolution
Stephen Floor, Adrian Melott, and Patrick Motl
The rate of galaxy cluster eccentricity evolution is useful in understanding large scale structure. Rapid evolution for 0.13 has been found in two different observed cluster…
Quantifying the Bull's Eye Effect
Brian C. Thomas, Adrian L. Melott, Hume A. Feldman +1
We have used N-body simulations to develop two independent methods to quantify redshift distortions known as the Bull's Eye effect (large scale infall plus small scale virial motio…
Optimal Moments for the Analysis of Peculiar Velocity Surveys II: Testing
Hume A. Feldman, Richard Watkins, Adrian L. Melott +1
Analyses of peculiar velocity surveys face several challenges, including low signal--to--noise in individual velocity measurements and the presence of small--scale, nonlinear flows…
