We study the distribution of dark matter in the nonlinear regime in a model in which the primordial fluctuations include, in addition to the dominant primordial Gaussian fluctuations generated by the standard $\Lambda CDM$ cosmological model, the effects of a cosmic string wake set up at the time of equal matter and radiation, making use of cosmological $N$-body simulations. At early times the string wake leads to a planar overdensity of dark matter. We study how this non-Gaussian pattern of a… 
Cosmic String Wake Detection using 3D Ridgelet Transformations
Three-dimensional ridgelet statistics are used to search for the signals of cosmic string wakes in the distribution of dark matter. We compare N-body simulations of the dark matter distribution in
Cosmic filaments from cosmic strings
Cosmic strings are generically predicted in many extensions of the Standard Model of particle physics. We propose a new avenue for detecting cosmic strings through their effect on the filamentary

In this paper, we describe the results of N-body simulation runs, which include a cosmic string wake of tension Gμ= 4 × 10−8 on top of the usual Λ CDM fluctuations. To obtain a higher resolution of
Extracting the signal of cosmic string wakes from 21-cm observations
A cosmic string wake produces a distinct non-Gaussian signal in 21-cm intensity maps at redshifts above that of reionization. While the string signal is (locally) larger in amplitude than the signal
On the possible enhancement of the global 21-cm signal at reionization from the decay of cosmic string cusps
We consider cosmic string cusp annihilations as a possible source of enhancement to the global background radiation temperature in 21-cm photons at reionization. A soft photon spectrum is induced via
Intermediate mass black hole seeds from cosmic string loops
We demonstrate that cosmic string loops may provide a joint resolution of two mysteries surrounding recently observed black holes. For a string tension in an appropriate range, large radius string
Planck limits on cosmic string tension using machine learning
We develop two parallel machine-learning pipelines to estimate the contribution of cosmic strings (CSs), conveniently encoded in their tension (Gμ), to the anisotropies of the cosmic microwave
A Cosmological Lithium Solution from Discrete Gauged Baryon Minus Lepton Number
We propose the infrared gauge symmetry of our sector includes an unbroken discrete gauged subgroup of baryon minus lepton number of order 2 × 3 colors × 3 generations. We UV complete this at a scale

Disruption of Cosmic String Wakes by Gaussian Fluctuations
We study the stability of cosmic string wakes against the disruption by the dominant Gaussian fluctuations which are present in cosmological models. We find that for a string tension given by $G \mu
Signature of cosmic string wakes in the CMB polarization
We calculate a signature of cosmic strings in the polarization of the cosmic microwave background. We find that ionization in the wakes behind moving strings gives rise to extra polarization in a set
Cosmic String Wakes
Accretion of matter onto wakes left behind by horizon-sized pieces of cosmic string is investigated, and the effects of wakes on the large-scale structure of the universe are determined. Accretion of
Cosmic string loop distribution on all length scales and at any redshift
We analytically derive the expected number density distribution of Nambu-Goto cosmic string loops at any redshift soon after the time of string formation to today. Our approach is based on the
Spectral Analysis of Microwave Background Perturbations Induced by Cosmic Strings
Using a simple analytic model based on seed superposition we obtain the spectrum of microwave background perturbations induced by cosmic strings on all angular scales larger than about 2 armin. We

We present the first field-theoretic calculations of the contribution made by cosmic strings to the temperature power spectrum of the cosmic microwave background (CMB). Unlike previous work, in which
The 21 cm signature of cosmic string wakes
We discuss the signature of a cosmic string wake in 21cm redshift surveys. Since 21cm surveys probe higher redshifts than optical large-scale structure surveys, the signatures of cosmic strings are
Wouthuysen-Field absorption trough in cosmic string wakes
The baryon density enhancement in cosmic string wakes leads to a stronger coupling of the spin temperature to the gas kinetic temperate inside these string wakes than in the intergalactic medium
Microwave anisotropy due to cosmic strings
There has been much interest in the cosmological consequences of line-like topological defects (‘cosmic strings’) which may be produced in a phase transition in the early Universe1–8. Such strings
Dissipationless clustering of neutrinos in cosmic-string-induced wakes.
TLDR
This work studies the dissipationless clustering of neutrinos in cosmic-string-induced wakes using an analysis based on the Gilbert equation, i.e., taking into account the velocity dispersion of neutRinos.
