Probing the imprint of interacting dark energy on very large scales
(American Physical Society, 2015)
The observed galaxy power spectrum acquires relativistic corrections from light-cone effects, and these corrections grow on very large scales. Future galaxy surveys in optical, infrared and radio bands will probe increasingly ...
Nonlinear modulation of the HI power spectrum on ultra-large scales. I
(IOP Science, 2015)
Intensity mapping of the neutral hydrogen brightness temperature promises to provide a three-dimensional view of the universe on very large scales. Nonlinear effects are typically thought to alter only the small-scale ...
