Matter in the Universe is arranged in a cosmic web, with a filament of matter typically connecting each neighbouring galaxy pair, separated by tens of millions of light-years. A quadrupolar pattern of the spin field around filaments is known to influence the spins of galaxies and haloes near them, but it remains unknown whether filaments themselves spin. Here, we measure dark matter velocities around filaments in cosmological simulations, finding that matter generally rotates around them…

Observational search for primordial chirality violations using galaxy angular momenta
We search for evidence of primordial chirality violation in the galaxy data from the Sloan Digital Sky Survey by comparing how strongly directions of galaxy angular momenta correlate with left and

An observed correlation between galaxy spins and initial conditions
The directions of the galaxy angular momenta can be predicted from the initial conditions of the early Universe through the tidal torque. In simulations, these directions are well preserved through
Angular momentum growth in protogalaxies
An analysis by Doroshkevich (1970) which shows that the angular momentum of galaxies grew to first order (in proportion to t) during the linear phases of protogalactic evolution is expanded. This
The Cosmic Web: Geometric Analysis
The lecture notes describe the Delaunay Tessellation Field Estimator for Cosmic Web analysis. The high sensitivity of Voronoi/Delaunay tessellations to the local point distribution is used to obtain
Angular momentum and the absence of vortices in the cores of fuzzy dark matter haloes
Scalar Field Dark Matter (SFDM), comprised of ultralight (& 10 eV) bosons, is distinguished from massive (& GeV), collisionless Cold Dark Matter (CDM) by its novel structure-formation dynamics as
Deviations from tidal torque theory: Evolution of the halo spin–filament alignment
The alignment between halo spins and the cosmic web is still poorly understood despite being a widely studied topic. Here, we study this alignment within the context of tidal torque theory (TTT) and
Vortices and waves in light dark matter
In a galactic halo like the Milky Way, bosonic dark matter particles lighter than about 100 eV have a de Broglie wavelength larger than the average inter-particle separation and are therefore well
Second-order Fermi Reacceleration Mechanisms and Large-Scale Synchrotron Radio Emission in Intracluster Bridges.
The role of second-order Fermi mechanisms for the reacceleration of relativistic electrons interacting with turbulence in these peculiar regions is explored for the first time and steep spectrum and volume filling synchrotron emission can be generated in the entire intracluster bridge region.
A gravitational lensing detection of filamentary structures connecting luminous red galaxies
We present a weak lensing detection of filamentary structures in the cosmic web, combining data from the Kilo-Degree Survey, the Red Cluster Sequence Lensing Survey, and the Canada-France-Hawaii
And yet it flips: connecting galactic spin and the cosmic web
We study the spin alignment of galaxies and haloes with respect to filaments and walls of the cosmic web, identified with DisPerSE , using the Simba simulation from z = 0 − 2. Massive haloes’ spins
