The Global 21 cm Signal of a Network of Cosmic String Wakes
Oscar F. Hernández
In previous works we discussed the 21 cm signature of a single cosmic string wake. However the 21 cm brightness temperature is influenced by a network of cosmic string wakes, and n…

A Bayesian Framework for Cosmic String Searches in CMB Maps
Razvan Ciuca, Oscar F. Hernández
There exists various proposals to detect cosmic strings from Cosmic Microwave Background (CMB) or 21 cm temperature maps. Current proposals do not aim to find the location of strin…

The 21 cm Signature of Cosmic String Wakes
Robert H. Brandenberger, Rebecca J. Danos, Oscar F Hernandez +1
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 c…
