Anisotropic Counts-in-Cells in Redshift Space: A New Route to Cosmological Constraints from Galaxy Surveys
Paweł Drozda, Wojciech A. Hellwing, Maciej Bilicki
We introduce a novel extension of the volume-averaged correlation function (VACF) framework by replacing the traditional spherical smoothing kernels with anisotropic, ellipsoidal w…
Skewness as a Probe of Gravity: Real and Redshift Space Counts-In-Cells
Paweł Drozda, Wojciech A. Hellwing, Maciej Bilicki
We study the counts-in-cells reduced skewness for dark matter, halo, and galaxy distributions in both real and redshift space, using the ELEPHANT ($\textit{Extended LEnsing P…
Iteratively Comparing Gravitational-Wave Observations to the Evolution of Massive Stellar Binaries
Vera Delfavero, Richard O'Shaughnessy, Krzysztof Belczynski +2
Gravitational-wave observations have the capability to strongly differentiate between different assumptions for how binary compact objects form. In this work, we show how to carefu…
Galaxy and halo angular clustering in LCDM and Modified Gravity cosmologies
Paweł Drozda, Wojciech A. Hellwing, Maciej Bilicki
Using a suite of -body simulations we study the angular clustering of galaxies, halos, and dark matter in and Modified Gravity (MG) scenarios. We consider…
Differentiating small-scale subhalo distributions in CDM and WDM models using persistent homology
Jessi Cisewski-Kehe, Brittany Terese Fasy, Wojciech Hellwing +3
The spatial distribution of galaxies at sufficiently small scales will encode information about the identity of the dark matter. We develop a novel description of the halo distribu…
