Why does the Jeans Swindle work?
M. Falco, S. H. Hansen, R. Wojtak +1
When measuring the mass profile of any given cosmological structure through internal kinematics, the distant background density is always ignored. This trick is often refereed to a…
Spatial Anisotropy of Galaxy Kinematics in Sloan Digital Sky Survey Galaxy Clusters
Andreas Skielboe, Radoslaw Wojtak, Kristian Pedersen +2
Measurements of galaxy cluster kinematics are important in understanding the dynamical state and evolution of clusters of galaxies, as well as constraining cosmological models. Whi…
Physical properties underlying observed kinematics of satellite galaxies
Radoslaw Wojtak, Gary A. Mamon
We study the kinematics of satellites around isolated galaxies selected from the Sloan Digital Sky Survey (SDSS) spectroscopic catalog. Using a model of the phase-space density pre…
