The Secondary Spin Bias of Dark Matter Haloes
James W. Johnson, Ariyeh H. Maller, Andreas A. Berlind +2
We investigate the role of angular momentum in the clustering of dark matter haloes. We make use of data from two high-resolution N-body simulations spanning over four orders of ma…
The Ultraviolet Detection of Diffuse Gas in Galaxy Groups
John T. Stocke, Brian A. Keeney, Charles W. Danforth +5
A small survey of the UV-absorbing gas in 12 low- galaxy groups has been conducted using the Cosmic Origins Spectrograph (COS) on-board the Hubble Space Telescope (HST). Targets…
Likelihood Non-Gaussianity in Large-Scale Structure Analyses
ChangHoon Hahn, Florian Beutler, Manodeep Sinha +3
Standard present day large-scale structure (LSS) analyses make a major assumption in their Bayesian parameter inference --- that the likelihood has a Gaussian form. For summary sta…
