Primordial black holes in the Dark Ages: Observational prospects for future 21cm surveys
Katherine J. Mack, Daniel H. Wesley
We consider the signatures of a population of primordial black holes (PBHs) in future observations of 21cm radiation from neutral hydrogen at high redshift. We focus on PBHs in the…
New no-go theorems for cosmic acceleration with extra dimensions
Daniel H. Wesley
We describe new no-go theorems for producing four-dimensional accelerating universes from warped dimensional reduction. The new theorems improve upon previous results by including…
Magnetogenesis from Cosmic String Loops
Diana Battefeld, Thorsten Battefeld, Daniel H. Wesley +1
Large-scale coherent magnetic fields are observed in galaxies and clusters, but their ultimate origin remains a mystery. We reconsider the prospects for primordial magnetogenesis b…
Observing cosmic string loops with gravitational lensing surveys
Katherine J. Mack, Daniel H. Wesley, Lindsay J. King
We show that the existence of cosmic strings can be strongly constrained by the next generation of gravitational lensing surveys at radio frequencies. We focus on cosmic string loo…
