Marked correlation functions in perturbation theory
Alejandro Aviles, Kazuya Koyama, Jorge L. Cervantes-Cota +2
We develop perturbation theory approaches to model the marked correlation function constructed to up-weight low density regions of the Universe, which might help distinguish modifi…
Collapse of spherical overdensities in superfluid models of dark matter
S. T. H. Hartman, H. A. Winther, D. F. Mota
We intend to understand cosmological structure formation within the framework of superfluid models of dark matter with finite temperatures. Of particular interest is the evolution…
Hybrid : general, unified, non-linear matter power spectrum in redshift space
Benjamin Bose, Hans A. Winther, Alkistis Pourtsidou +4
Constraints on gravity and cosmology will greatly benefit from performing joint clustering and weak lensing analyses on large-scale structure data sets. Utilising non-linear inform…
SCALAR: an AMR code to simulate axion-like dark matter models
Mattia Mina, David F. Mota, Hans A. Winther
We present a new code, SCALAR, based on the high-resolution hydrodynamics and N-body code RAMSES, to solve the Schrödinger equation on adaptive refined meshes. The code is intended…
Beyond BAO: improving cosmological constraints from BOSS with measurement of the void-galaxy cross-correlation
Seshadri Nadathur, Paul M. Carter, Will J. Percival +2
We present a measurement of the anisotropic void-galaxy cross-correlation function in the CMASS galaxy sample of the BOSS DR12 data release. We perform a joint fit to the data for…
Emulators for the non-linear matter power spectrum beyond CDM
Hans Winther, Santiago Casas, Marco Baldi +4
Accurate predictions for the non-linear matter power spectrum are needed to confront theory with observations in current and near future weak lensing and galaxy clustering surveys.…
