The angular momentum of dark matter haloes controls their spin magnitude and orientation, which in turn influences the galaxies therein. However, the process by which dark matter haloes acquire angular momentum is not fully understood. We present an extension to the genetic modification technique which allows us to control the angular momentum of any region in the initial conditions. Using a suite of simulations, we investigate whether changes to the angular momentum of a specified region in…

Asymmetry in Galaxy Spin Directions—Analysis of Data from DES and Comparison to Four Other Sky Surveys

The paper shows an analysis of the large-scale distribution of galaxy spin directions of 739,286 galaxies imaged by DES. The distribution of the spin directions of the galaxies exhibits a large-scale

Spin Alignment of Dark Matter Halos: Fast Halos

We investigate the spin alignment of dark matter halos by considering a mechanism somewhat similar to tidal locking; we dub it tidal-locking theory (TLT). While tidal torque theory (TTT) is

The causal effect of environment on halo mass and concentration

Understanding the impact of environment on the formation and evolution of dark matter haloes and galaxies is a crucial open problem. Studying statistical correlations in large simulated populations

QuasarNet: A new research platform for the data-driven investigation of black holes

QuasarNet demonstrates the power of ML, in analyzing and exploring large datasets, and also offers a unique opportunity to interrogate the theoretical assumptions that underpin accretion and feedback models.

Statistical exploration of halo anisotropic clustering and intrinsic alignments with the mass-Peak Patch algorithm

The anisotropy or triaxiality of massive dark matter haloes largely defines the structure of the cosmic web, in particular the filaments that join the haloes together. Here, we investigate such



GenetIC—A New Initial Conditions Generator to Support Genetically Modified Zoom Simulations

We present genetIC, a new code for generating initial conditions for cosmological N-body simulations. The code allows precise, user-specified alterations to be made to arbitrary regions of the

Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to investigate the

Testing tidal-torque theory – II. Alignment of inertia and shear and the characteristics of protohaloes

We investigate the cross-talk between the two key components of tidal-torque theory, the inertia (I) and shear (T) tensors, using a cosmological N-body simulation with thousands of well-resolved

Testing tidal-torque theory: I. spin amplitude and direction

We evaluate the success of linear tidal-torque theory (TTT) in predicting galactic-halo spin using a cosmological N-body simulation with thousands of well-resolved haloes. The protohaloes are
