The Wouthuysen Field Absorption Trough in Cosmic Strings Wakes
Oscar F. Hernandez
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 interg…
The 21 cm Signature of Shock Heated and Diffuse Cosmic String Wakes
Oscar F. Hernandez, Robert H. Brandenberger
The analysis of the 21 cm signature of cosmic string wakes is extended in several ways. First we consider the constraints on from the absorption signal of shock heated wakes l…
The High-Redshift Neutral Hydrogen Signature of an Anisotropic Matter Power Spectrum
Oscar F. Hernandez, Gilbert P. Holder
An anisotropic power spectrum will have a clear signature in the 21cm radiation from high-redshift hydrogen. We calculate the expected power spectrum of the intensity fluctuations…
Angular 21 cm Power Spectrum of a Scaling Distribution of Cosmic String Wakes
Oscar F. Hernandez, Yi Wang, Robert Brandenberger +1
Cosmic string wakes lead to a large signal in 21 cm redshift maps at redshifts larger than that corresponding to reionization. Here, we compute the angular power spectrum of 21 cm…
Higgs Central Exclusive Production
J. R. Cudell, A. Dechambre, O. F. Hernández
We tune the calculation of central exclusive Higgs production to the recent CDF central exclusive dijet data, and predict the cross section for the exclusive production of Higgs bo…
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…
