Fast generation of mock galaxy catalogues in modified gravity models with COLA

Bartolomeo Fiorini, Kazuya Koyama, Albert Izard +3

We investigate the viability of producing galaxy mock catalogues with COmoving Lagrangian Acceleration (COLA) simulations in Modified Gravity (MG) models employing the Halo Occupat…

Dynamical friction in Bose-Einstein condensed self-interacting dark matter at finite temperatures, and the Fornax dwarf spheroidal

S. T. H. Hartman, H. A. Winther, D. F. Mota

The aim of the present work is to better understand the gravitational drag forces, i.e. dynamical friction, acting on massive objects moving through a self-interacting Bose-Einstei…

Testing Low-Redshift Cosmic Acceleration with Large-Scale Structure

Seshadri Nadathur, Will J. Percival, Florian Beutler +1

We examine the cosmological implications of measurements of the void-galaxy cross-correlation at redshift combined with baryon acoustic oscillation (BAO) data at $0.1<z<2.…

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…
