Zeldovich pancakes in observational data are cold
T. Brinckmann, M. Lindholmer, S. H. Hansen +1
The present day universe consists of galaxies, galaxy clusters, one-dimensional filaments and two-dimensional sheets or pancakes, all of which combine to form the cosmic web. The s…
A new method to measure the mass of galaxy clusters
Martina Falco, Steen H. Hansen, Radoslaw Wojtak +3
The mass measurement of galaxy clusters is an important tool for the determination of cosmological parameters describing the matter and energy content of the Universe. However, the…
Dynamical signatures of infall around galaxy clusters: a generalized Jeans equation
Martina Falco, Gary A. Mamon, Radoslaw Wojtak +2
We study the internal kinematics of galaxy clusters in the region beyond the sphere of virialization. Galaxies around a virialized cluster are infalling towards the cluster centre…
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…
