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 $G \mu = 10^{-7}$ wakes remain locally stable until a redshift of $z = 6$, and for a value of $G \mu = 10^{-14}$ they are stable beyond a redshift of $z = 20$. We study a global stability criterion which shows that wakes created by strings at times after $t_{eq}$ are identifiable up to the present time…

Dark matter distribution induced by a cosmic string wake in the nonlinear regime
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…
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…
Searching for cosmic strings in CMB anisotropy maps using wavelets and curvelets
We use wavelet and curvelet transforms to extract signals of cosmic strings from simulated cosmic microwave background (CMB) temperature anisotropy maps, and to study the limits on the cosmic string…
Diffusion of massive particles around an Abelian-Higgs string
We study the diffusion of massive particles in the space time of an Abelian Higgs string. The particles in the early universe plasma execute Brownian motion. This motion of the particles is modeled…
Information theoretic bounds on cosmic string detection in CMB maps with noise
TLDR
An information theoretic bound on the detection of the cosmic string tension $G\mu$ from CMB maps in terms of the resolution, noise level and total survey area of the CMB map is derived.

We study the signal of cosmic string wakes present before the time of reionization in the cross-correlation signal of 21-cm redshift and B-mode CMB polarization maps. The specific non-Gaussian signal…

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…
