Reversing Arrested Development: A New Method to Address Halo Assembly Bias
William Smith, Andreas Berlind, Manodeep Sinha
Halo assembly bias is a phenomenon whereby the clustering of dark matter halos is dependent on halo properties, such as age, at fixed mass. Understanding the origin of assembly bia…
Corrfunc --- A Suite of Blazing Fast Correlation Functions on the CPU
Manodeep Sinha, Lehman H. Garrison
The two-point correlation function (2PCF) is the most widely used tool for quantifying the spatial distribution of galaxies. Since the distribution of galaxies is determined by gal…
The 21cm bispectrum during reionization: a tracer of the ionization topology
Anne Hutter, Catherine A. Watkinson, Jacob Seiler +3
We compute the bispectra of the 21cm signal during the Epoch of Reionization for three different reionization scenarios that are based on a dark matter N-body simulation combined w…
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…
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…
Spatial Clustering of Dark Matter Halos: Secondary Bias, Neighbor Bias, and the Influence of Massive Neighbors on Halo Properties
Andrés N. Salcedo, Ariyeh H. Maller, Andreas A. Berlind +5
We explore the phenomenon commonly known as halo assembly bias, whereby dark matter halos of the same mass are found to be more or less clustered when a second halo property is con…
