Local primordial non-Gaussianity from the large-scale clustering of photometric DESI luminous red galaxies
We use angular clustering of luminous red galaxies from the Dark Energy Spectroscopic Instrument (DESI) imaging surveys to constrain the local primordial non-Gaussianity parameter fNL.
To beta or not to beta: can higher-order Jeans analysis break the mass-anisotropy degeneracy in simulated dwarfs?
A non-parametric higher-order Jeans analysis method, GravSphere, was recently used to constrain the density profiles of Local Group dwarf galaxies, classifying them into those that are more likely to have an inner dark matter cusp and those that are likely to have a core (Read et al.).

A Lightcone Catalogue from the Millennium-XXL Simulation
A Monte Carlo HOD method is used to assign galaxies to the halo lightcone catalogue, and we evolve the HODs to reproduce a target luminosity function; by construction, the luminosity function of galaxies in the mock is in agreement with the Sloan Digital Sky Survey (SDSS) at low redshifts and the Galaxy and Mass Assembly (GAMA) survey at high redshifts.

A unified model for the spatial and mass distribution of subhaloes
N-body simulations suggest that the substructures that survive inside dark matter haloes follow universal distributions in mass and radial number density.

The orbital PDF: general inference of the gravitational potential from steady-state tracers
We develop two general methods to infer the gravitational potential of a system using steady-state tracers, i. e., tracers with a time-independent phase-space distribution.

Simulating the joint evolution of quasars, galaxies and their large-scale distribution
The cold dark matter model has become the leading theoretical paradigm for the formation of structure in the Universe.

Theoretical Models of the Halo Occupation Distribution: Separating Central and Satellite Galaxies
In agreement with earlier results for dark matter subhalos, we find that the mean occupation function <N> for galaxies above a baryonic mass threshold can be approximated by a step function for central galaxies plus a power law for satellites, and that the distribution of satellite numbers is close to Poisson at fixed halo mass.
