Cosmic variance in the nanohertz gravitational wave background
Elinore Roebber, Gilbert Holder, Daniel Holz +1
We use large N-body simulations and empirical scaling relations between dark matter halos, galaxies, and supermassive black holes to estimate the formation rates of supermassive bl…
Disentangling redshift-space distortions and nonlinear bias using the 2D power spectrum
Elise Jennings, Risa H. Wechsler, Samuel W. Skillman +1
We present the nonlinear 2D galaxy power spectrum, , in redshift space, measured from the Dark Sky simulations, using galaxy catalogs constructed with both halo occupation…
The dark matter of galaxy voids
P. M. Sutter, Guilhem Lavaux, Benjamin D. Wandelt +2
How do observed voids relate to the underlying dark matter distribution? To examine the spatial distribution of dark matter contained within voids identified in galaxy surveys, we…
Voids in the SDSS DR9: observations, simulations, and the impact of the survey mask
P. M. Sutter, Guilhem Lavaux, Benjamin D. Wandelt +3
We present and study cosmic voids identified using the watershed void finder VIDE in the Sloan Digital Sky Survey Data Release 9, compare these voids to ones identified in mock cat…
Sparse sampling, galaxy bias, and voids
P. M. Sutter, Guilhem Lavaux, Nico Hamaus +3
To study the impact of sparsity and galaxy bias on void statistics, we use a single large-volume, high-resolution N-body simulation to compare voids in multiple levels of subsample…
On the Rates of Type Ia Supernovae in Dwarf and Giant Hosts with ROTSE-IIIb
Robert M. Quimby, Fang Yuan, Carl Akerlof +2
We present a sample of 23 spectroscopically confirmed Type Ia supernovae that were discovered in the background of galaxy clusters targeted by ROTSE-IIIb and use up to 18 of these…
