Measuring the X-ray luminosities of SDSS DR7 clusters from RASS
Lei Wang, Xiaohu Yang, Shiyin Shen +8
We use ROSAT All Sky Survey (RASS) broadband X-ray images and the optical clusters identified from SDSS DR7 to estimate the X-ray luminosities around candidate cluste…
On the cross-section of Dark Matter using substructure infall into galaxy clusters
David Harvey, Eric Tittley, Richard Massey +6
We develop a statistical method to measure the interaction cross-section of Dark Matter, exploiting the continuous minor merger events in which small substructures fall into galaxy…
Weighing Galaxy Clusters with Gas. II. On the Origin of Hydrostatic Mass Bias in LambdaCDM Galaxy Clusters
Kaylea Nelson, Erwin T. Lau, Daisuke Nagai +2
The use of galaxy clusters as cosmological probes hinges on our ability to measure their masses accurately and with high precision. Hydrostatic mass is one of the most common metho…
Predicting Merger-Induced Gas Motions in Lambda-CDM Galaxy Clusters
Daisuke Nagai, Erwin T. Lau, Camille Avestruz +2
In the hierarchical structure formation model, clusters of galaxies form through a sequence of mergers and continuous mass accretion, which generate significant random gas motions…
Weighing Galaxy Clusters with Gas. I. On the Methods of Computing Hydrostatic Mass Bias
Erwin T. Lau, Daisuke Nagai, Kaylea Nelson
Mass estimates of galaxy clusters from X-ray and Sunyeav-Zel'dovich observations assume the intracluster gas is in hydrostatic equilibrium with their gravitational potential. Howev…
